The Quanta LB4M – Cheap White Box Switching?

Quanta LB4M

Hey,” said my friend, “are you interested in buying an Ethernet switch? 48 1Gbps copper ports and two 10Gbps fiber uplinks. Very cheap. Layer 2 only, though.” A few minutes later, we were doing business out of the trunk of his automobile. And you thought that was just a cliché, right?

And so a largely unbranded Quanta LB4M switch has entered my life (and my home network). Let’s spin it up and see what this hunk o’ junk has to offer.

Quanta LB4M Specs

First off, the switch is sporting a pretty reasonable spec. The full specifications are in this PDF – it’s the QSSC-LB400GR model. This 1U switch has a 96Gbps backplane, optional redundant PSUs (mine only has one, though) all built around the Broadcom BCM 56514 chip (two of them, I believe). It’s stackable, in theory, and according to the data sheet it supports a whole bunch of IPv4 and IPv6 protocols. Cool, and phenomenal value for the price (check out eBay to see lots of similar auctions if you’re interested).

It seems that the LB4M is a classic merchant silicon ODM (Original Design Manufacturer) type box, rebranded for sale (from what I can see) by HP and Dell, and possibly others. It’s a little hard to tell, to be honest, but Quanta assures me that the just sell the hardware platform and it’s up to the vendor to put software on it. Ah yes, the software – let’s look at that.

Layer 3 Capabilities

Yeah, but no. The switch says this about itself:

(quanta) #show ver
Switch: 1

System Description............................. FASTPATH Switching
Machine Type................................... LB4G 48x1G 2x10G
Machine Model.................................. LB4M

Additional Packages............................ FASTPATH QOS

The word “Switching” is the key here. This is definitely (as advised by my friend) a layer 2 device. That’s rather odd given that the data sheet clearly said it was a Layer 2 / Layer 3 device with multiple protocol support; however this is clearly something that has to be enabled in software, and the software we have does not support it.

Software and CLI

The switch is apparently running VxWorks5.5.1 / FASTPATH, about which the documentation on the interwebs is flaky at best. Interestingly there is a manual on the web for a L2/L3/QOS Quanta LB4M which has all the lovely routing features that the spec sheet promises. However, based on web searches it seems that nobody has that elusive version of code for which the massive manual was created. In fact everything about the manual is wrong compared to what I have, down to the default console port speed setting, so heaven only knows where the routing code is! (if you know, please tell me!).

In terms of CLI, it’s not often that I recommend trying the web interface on a device, but this is one of those moments. I can safely confirm that I hate the command line interface with a passion. I have been assured that users of certain HP/Dell devices will find a wincing familiarity with the whole system, though others say if you know Cisco IOS you’ll feel right at home. Well, I have a passing familiarity with IOS and I did not feel at home. Your mileage, as they say, may vary.

Web Interface

Well, it’s functional if not pretty. The port status picture at the top is Java based, and I had to add a security exception to allow it to run.

Quanta Fastpath WebUIThe web interface is a little bit clunky, but at least everything is there for you to find eventually.


I’ve enabled LLDP on four ports. This has to be done on a per port basis, so I did so on the four ports that I have configured as a port-channel to my Juniper EX3200. Curiously, one (and sometimes two) of them don’t show up on the Juniper as LLDP neighbors (though all four links are up and apparently part of the port-channel). I have no idea what’s going on and I wish it worked properly, but hey, I guess it’s just LLDP. I confirmed that the Juniper (hostname “noisy”) is sending LLDP packets, but nothing is being received form the Quanta:

john@noisy> monitor traffic interface ge-0/0/15
Listening on ge-0/0/15, capture size 96 bytes

21:33:09.673205 Out LLDP, name noisy, length 60
21:33:38.094759 Out LLDP, name noisy, length 60
21:34:06.146594 Out LLDP, name noisy, length 60

Out of interest, yesterday three of the links showed in LLDP. Today, after shutting the ae0 interface down and re-enabling it tonight, only two of the four show up! Obviously a correctly-functioning interface would look like this:

john@noisy> monitor traffic interface ge-0/0/8
Listening on ge-0/0/8, capture size 96 bytes

21:36:30.539813  In LLDP, name quanta, length 60
21:36:43.606446 Out LLDP, name noisy, length 60
21:36:59.340468  In LLDP, name quanta, length 60
21:37:09.914005 Out LLDP, name noisy, length 60

Help Me Out?

I’m assuming that whoever had this switch in the past was one of the big data center owners – an Amazon, Facebook, Google or similar. My suspicion is that they wrote their own OS to run on the Quanta LB4M hardware, and before selling them on they put on this rather crippled OS so it would run. If you work for any of those folks and can confirm or deny that you have or had Quanta LB4Ms in your data centers, I would simply love to hear from you just so I know if I’m right about the OS. Maybe you’ve even heard of this wonderful routing code for the LB4M that I’m being teased about.

Meanwhile the switch it up, it’s a heck of a switch for the price, and I’m going to start testing it shortly. I’m hopeful that things like the LLDP oddity are just that – an oddity – and not an indication of more serious underlying problems.

Side Note

My switch came with two 10G SFP+ SR optics in the uplink ports (49 + 50); why did I not use those to link to the EX3200? Because my poor little EX3200 does not have the necessary additional modules to do so, and looking on ebay they are just a touch pricy. While I’d love a 20Gbps link between my switches simply for nerd value, I think I can live with a (currently) 4Gbps port-channel for the moment.

If you’ve used one of these switches, I’d welcome your thoughts and experiences.

  1. Hi, you can use the EX-UM-2X4SFP module for EX3200 to host up to 2 x 10G SFP+ transceivers; that module can house up to 2 x 10G SFP+ transceivers (either Singlemode, or Multimode) on EX3200. you can buy the module from ebay for only $430 from here: http://www.ebay.com/itm/Juniper-EX-UM-2X4SFP-4-Port-SFP-Module-w-2x-10G-slots-for-EX3200-EX4200-/381042729480?pt=US_Network_Switch_Modules&hash=item58b7eaa208

    For the 10G SFP+ Multimode SR Transceiver, you can also buy it from ebay for $95 per unit (you can buy 2 x units for each EX-UM-2X4SFP module on EX3200): http://www.ebay.com/itm/Juniper-Original-EX-SFP-10GE-SR-EX-Series-10GB-SFP-SFPP-10GE-SR-740-021308-/190959589446?pt=US_Network_Switches&hash=item2c76141846

    I already has this configuration and it works great.

    EX3200 and EX4200 are the best Ethernet switches that ever made; i even running BGP on them!

    • If this were at work, where the pockets are deeper, purchasing the module and SFPs would not be an issue. However, since this is for my home network I cannot in all conscience pay around $630 for some (admittedly cool) uplinks in comparison to grabbing 4 Cat 5e cables from my “bucket-o-network-cables” and plugging them in. And that’s primarily why my EX3200 continues to have no 10G module 😉

      • you are right; you don’t even need a 2 x 10G SFP+ Link Aggregation Group (20G LAG) for a home network, as all your home traffic will not reach 20G.

        the most important thing that you are having EX3200 switch that has all Layer-2 and Layer-3 protocols that you can test on the built-in 1G RJ-45 copper ports, and use it as a big Core switch for your LAN-enables devices!

        • Exactly so. I use the EX3200 as the core switch/router for the home and lab environments.

          I’m almost tempted to pick up another of the LB4M switches just to physically isolate all my lab devices, but maybe that’s going a little too far, especially as in my house the line between “lab” and “home network” is distinctly blurred 😉

          • With a switch so cheap, to me it makes sense to have multiple ones if you need them. 🙂 At some point, it is worth it to have as just a warm/hot spare (and spare PS). Honestly, while I have several Cisco and Juniper switches in my lab at home, when going for a “cheap” gigabit switch, I opted for a low-cost Dell with 16 ports, because it was cheap and quiet. If I could get a quiet 24 or 48 port gig switch for just a little more, I would have jumped on it. You didn’t mention how loud you thought the switch was. I could infer a little as the switch was named quanta instead of “noisy2”. 🙂 I never put my EX4200/3200’s where people are, cause like Huey Lewis said in back to the future, “I’m afraid you’re just too darned loud!”

            Ref: http://www.youtube.com/watch?v=YmoU1bAzDiE


          • Haha 😉 Noise-wise it’s about average. Noisy is right below it in the rack (give or take some cable management) and it’s all in a closet under the stairs so at that point I don’t worry too much about the noise so long as it doesn’t whine or buzz. It certainly has a complement of fans, and I have seen others complaining about how noisy the switch is on the intarwebs. I guess it’s about the same as the EX3200 from what I can tell, but after a while the intense white noise in the closet fills my head and I can’t brain any more anyway.

  2. also you can use SFP+ DAC 10G Copper cables, if you don’t want to use Fiber. it is available from Juniper in 1, 3, 5, and 7 meters long, and it has SFP+ connector from each side, Juniper part#s:





    you can find them for cheap prices on ebay, or find 3rd party equivalent of these DAC cables for cheaper prices

  3. Disclaimer: I work for Cumulus Networks

    John, you are playing with Broadcom’s OS called ICOS or Fastpath and as you can see it has some issues around support and features. It is the barest of bare-metal OS. Some of the major vendors have played around with repackaging this and also the ODMs have used it as the OS when there was nothing else.

    Now I think most of them prefer Cumulus over ICOS because we are a fully supported Linux OS with lots of features and automation tools but alas we do not run on that platform (it is really old, even for 1G). It is great that you point out the shortcomings because sometimes people wonder what the value of having a supported OS that runs across multiple bare-metal platforms is. Bare-metal was not successful even in many of the large datacenters because the OS and ecosystem were missing. All things Google made for themselves internally. FB is doing the same now and is very open about it.

    I have heard rumors of two of the big IaaS guys using platforms like this and going away from it because of the problems and lack of support. I don’t think Google would have used that particular switch. They had custom optics. See http://www.wired.com/2012/09/pluto-switch/all/ to read more…

    If you even would like to see what we have done for bare-metal with hands-on, we have a great online lab of real bare-metal switches with a self-paced guide and KB articles that will walk you through ZTP with Ansible and Puppet, sFlow, etc. Reach out to me on twitter and I can get you some time in the Cumulus Work Bench.

    best regards,


    • I will do that, thank you!

      Would you believe that as I drove into work this morning I was listening to the latest Software Gone Wild podcast (http://blog.ipspace.net/2014/10/cumulus-linux-in-real-life-on-software.html) with Matt Stone talking to Ivan Pepelnjak about Cumulus. The first thing I did when I got into the office was to check your HCL on the offchance that Cumulus had ever supported a limping old switch like mine! It’s a crazy small world sometimes.

      Thanks for your response and insights on my lump-o-metal!

      • John,

        Truth is stranger than fiction. That was a great podcast btw.

        There must be a lot of those switches out there because we get asked if we support it a lot! I know that there is L3 support on it also but I have not heard anything very good about the quality of the protocols. Believe it or not though, some people are using it. I know of a production Hadoop cluster in Japan. I will take Quagga anyday myself.

        • Hey Todd,

          Any chance we could sway a Cumulus developer (or anyone else out on the interwebs for that matter) to port a version for this switch with some crowdsourced funds? As there are a TON of these switches to be had second-hand, I honestly think you would win over a ton of netdev types with support for this switch as it would become the go to switch for home labs, ergo, you will have a lot of smart people wanting to get their hands on Cumulus software to play with it for a home lab. You port it and charge $99 for a perpetual license for this switch only and I think you’ve got marketing and make a few tens of thousands of dollars in sales.

          Or if crowdsourcing is the way to go, let me know how much I need to raise on kickstarter….although I think you’r marketing team should kick in a bit o’ change! 🙂


          • I’m in! Good idea. Would love to know if it’s even possible.

            (And this switch pre-dates ONIE of course…)

          • I just stumbled upon this blog post, is there any news on that front if this is even possible?


    • I’ve wondered that. I have yet to find the exact same switch in Dell or HP branding, though it looks awfully like they have similar devices. If anybody has insight into this, that would be very cool!

  4. EX3200/4200 are nosiy since they both have a powerful hi-frequency CPU for handling L2, and L3 protocols (OSPF, BGP, MPLS, etc…) and hi-performance dedicated ASIC packet forwarding engin (pfe), and therefore a redundant “noisy” fan system is installed on both of them to cool down CPU, PFE, and the PS. Note that i used cisco, hp , and dell, and no one can offer a switch that has all features available on Juniper EX4200/3200 with their budget range (EX3200/4200 is like a small Juniper MX router!! you can have a whole BGP routing table on each of them with up to 256,000 entries!!)

    If you don’t need advanced protocols like BGP and MPLS, you can use the quiet and Fanless Juniper EX2200-C-12T-2G switch; this switch has 12 x 1G RJ-45 ports + 2 x 1G dual personality ports (each can be used either as 10/100/1000 or SFP transceiver), it supports L2 , and L3 like static routing, RIP, OSPF, IGMP querier mode, etc…, it is the most compact feature-packed switch out there, and no other brand; cisco, hp, nor dell have a little switch like this with all these features.

    For quanta switch; i think it is useless, as you can use GNS3 1.1 software with a PC or server with multiple ports to emulate a switch or a router with the feature you want

    • The Quanta switch is far from useless, especially at the price (go look on ebay – they are seriously cheap). You simply can’t argue with a switch with this kind of port count and backplane for the money. I need L2 ports as much as I need L3; in fact I need way more L2 ports than L3 functions because I run a home network with a large number of devices attached to it. Thus even as a layer 2 multi-vlan switch is has a purpose, and since my EX3200 only has 24 ports, I’m better off using the cheaper Quanta ports for access then trunk the vlans over to the EX3200 for any routing. Would I prefer it if the Quanta routed, even if it were static routing? Sure. That doesn’t, IMO, make it useless though.

      By the way, I’m very happy with my EX3200 from a feature perspective. I also have a couple of SRX firewalls attached for lab purposes, and since they also have a pretty full feature set as well as firewalling capabilities (including multiple routing-instances and logical tunnel interfaces to allow you to build some pretty impressive topologies with very little hardware), I’m pretty set for Juniper L3 😉

      • Yes Quanta is pretty cheap, but as alternative you can get a cheap HP web-managed L2 switch with VLAN support, it is around $60 – $70 for 48 ports (HP 1810 series), and trunk it to your EX3200 (i did this configuration before), and since you are having Juniper SRX you can use it as a you home core router, and the other SRX as your core home Firewall ; i have 2 x SRX100 + 2 x EX4200 (Juniper unique EX4200 Virtual Chassis!!) + 4 x EX2200 + 3 x HP 1810 switches, one SRX100 i’m using it as an MPLS VPN end-point connected to the telecom company, and the other SRX100 as a Firewall. the 2 x EX4200 Virtual Chassis is used as Core switch and “IGMP Querier” for my converged Network (single triple-play network; Video, Voice, and Data Network), EX2200 and HP 1810 switches with IGMP snooping are trunk-ed to the EX4200 Virtual Chassis core switch, IPTV systems, Access Points, and workstations are connected to EX2200 and HP 1810 switches (access Layer switches).

        i will have Juniper MX5 router soon, to attach it to my network.

        After a long experience with playing with Cisco, HP, Dell, Juniper, Brocade, i found that Juniper is the best and second to non when it comes to triple-play/multi-play hi-speed Networks.

        So since you are having SRX devices in your home network you can use them as Core Router/ Firewall, and implement the fore-mentioned scenario,

        • Hi Abdellatif,

          If yopu can find an HP 1810-48 for the price point you mention ($75-$100), then that is certainly a cheap alternative. From looking around ebay for those, I couldn’t find the 48 port version for less than $400. Perhaps you have a better source or maybe the market has shifted on these and an excess that might have existed previously is now dried up. The Quanta switches, although their CLI leaves a little to be desired, are still a great switch with full VLAN abilities and a Web GUI if you prefer. While I would love to see Cumulus Linux on this switch, it’s not a bad switch for the price. What John needs to do is sell off his EX3200 and get an EX3300 to be his core switch/router and then hang a couple of Quanta LB4M’s off of it and have them connected via 10G. Just to mention, I’ve heard that Quanta is a multi-vendor ODM (original device manufacturer) and makes several of the Juniper switches as well. Of course, we all know that it is the JUNOS OS and the feature set that makes a Juniper switch better than the rest. This is a real testament to how valuable JUNOS really is. While everyone is still focused on interacting via CLI, JUNOS has got most people beat, but it will be interesting to see how this advantage shifts as SDN-controlled, CLI-less, programmatic infrastructures become the norm.


          • I brought 2 of the Quanta LB4M switches as well. Not sure what to do with them right now. I curious about the Juniper EX3300 switch. Is there a specific model of the EX3300 you would recommend? Please advise.

  5. Any model of EX3300 would do, but since even the 24 port model has 4 x 10Gig ports built-in, you could hang off 4 of the quanta switches to give yourself a massive amount of layer-2 switch ports (192 1gig ports may be a bit overkill for a home lab) and have each of the Quanta switches connected via a 10gig connection to the EX3300, which could do all of your routing for you, since it is layer 3 capable. Or you could go with 2 Quanta switches with a LAG of 2 x 10Gig connections to the EX3300 giving yourself a oversubscription ratio of just 2.4:1. The reason I suggested the EX3300 was because of the built-in 10gig ports and Layer 3 capabilities.

    Hope that helps!


    • It helps somewhat.. So here is my situation. I have 2 SAN Servers that I want connected to my VM Host using a 10gbe connection. I purchased the Quanta LB4M (has two 10gbe SFP+ uplink ports) and 2 Brocade 1020-R SFP+ network cards. One of my SAN Servers and VM Host is connected to the 10gbe SFP+ ports on the LB4M. So do I really need the Juniper EX3300 at all? Please advise.

      • Hi PG and NSG,

        when i worked with JUNOS, i found that it is the most efficient and feature-backed Network OS you could find out there; it also a way better than Cisco’s IOS.

        in fact, JUNOS depends on 802 IEEE standards, and will not cage you in to Cisco’s proprietary standards. Also JUNOS has “block-based” CLI, which make you feels that you working with object oriented programming languages like Java or C#.

        also if you can check JUNOS web interface you will find that 80 – 90% of the configurations can be done from that GUI (except some complex QoS/CoS and routing configurations).

        for PG question; let me tell you a scenario that i made recently to my client; i gave him the following:

        – iSCSI storage with two controllers, each controller has 2 x 10G SFP+ slots

        – 2 x Juniper EX3300-24T switches

        – multiple rack-mount server with 2 x 1G Ethernet each

        now, each 2 x 10G SFP+ on each storage controller was grouped together using LACP, and connected to 2 x 10G SFP+ LACP on each EX3300 switch using 10G DAC cables (SFP+ Twinax cable), the reaming 2 x 10G SFP+ slots on each EX3300 switch was utilized for “Virtual Chassis” connection between the 2 x EX3300 switches (a Juniper High availability feature on the switches level), each 1G port of each server is connected to each EX3300 switch; now all the servers are communicating with the storage in fully highly available connectivity; high availability on storage controllers level (dual controllers), on link level (LACP), on switches level (2 x EX3300 single VC), and on server connection level (2 x 1G link on each server).

        Load Balancing:

        if you have multiple VMs on each server you can configure your VMs to load balance between the 2 x 1G ports on each server,

        you can configure the 2 x storage controllers as Active/Active fashion, then you can assign a specific number of LUNs per each controller, so if one controller fails, all of its LUNs will failover to the reaming controller,

        the communication between the storage and the EX3300 switches will load balance and failover because we are using LACP between them.

        Now, regarding NSG question; there was a used HP 1810-48 switch on ebay on that day, but unfortunately it seems it sold out,

      • Hi PG,

        No, you can do what you want to do with the Quanta switches without the need for the Juniper switch. If you added another Quanta switch, you could LAG 8 x 1Gig connections (some switches don’t support more than 8 connections in a LAG) or so between the two switches and then connect your other SAN to one of the other 10gig ports. You will still have one additional 10gig port available if you want to connect another VM server. You may ask why not connect the two Quanta switches via the 10Gig connection, but you would be one port short for that and wouldn’t be able to get both of your SANs connected via 10Gig. No need for the Juniper unless you want to route, in which case, you will need something (like a EX3300 or similar) to provide the Layer 3 routing since John (the OP) points out, L3 capable code for the Quanta switches is quite elusive…We’ll keep our fingers crossed for a skunkworks port of Quagga or Cumulus (w/Quagga) or the like. 🙂


        • Hi NSG,

          I have 2 of the Quanta switches already.. So do I need a third or fourth one to do what you described above? They are cheap on Ebay. Just need to figure out how to do what you described in the WEB GUI of the Quanta switch.

  6. LB400GR switch:

    Configure the management ports switch:

    LOgin Admin,

    enable to enter the Privileged EXEC command mode,

    Disable DHCP for the management port:

    serviceport protocol none,

    Configure the management port IP address:

    serviceport ip ip-address netmask [gateway]


    serviceport ip

    show -running-config, then,

    write memory.

    Enable GUI http.


  7. Talking about “cheap”: Let´s throw in a fanless layer 2 24 port 1 GbE switch with 2 SFP+ 10GbE ports for 299$: Mikrotik CRS226-24G-2S+RM

  8. It would be great if someone detailed the instructions for creating a 8 port aggregation between 2 Quanta LB4m switches.

    Additionally I have noticed that it takes 20 to 25 seconds for a computer to establish a network connection to the LB4M switch. My computers are running Windows 8.1. It did not do this on my old network switch. Is there a setting on the switch to improve the connectivity time. I have enabled jumbo frames on all the ports on the LB4M switch. Need help….

    One more thing.. It would be great if folks post some of the settings that they have changed that would optimize this switch running in a home production environment.

    • 20-25 seconds sounds like standard Spanning Tree behavior on a port if it does not know it’s an Edge port. RSTP Edge ports are the equivalent of the old Cisco “portfast” feature, pretty much. I haven’t tested it on my LB4M yet (though I should shortly) but you should be able to configure the port as Edge, and it should come up as fast as you’re expecting. In the UI this is in System > Switching > Spanning-Tree > CST Port Configuration/Status. Pick your port number at the top and wait for the refresh, then scroll down to Auto Edge, and enable it. I’ll try to confirm shortly, but this looks like it should do the right thing.

    • Regarding the aggregation, would you prefer command line or web interface directions? It’s not difficult to do, but it’s also not as easy as it perhaps should be.

      • Thanks you so much for your quick response. As far setting up a LAG, can you provide the Web GUI instructions first. It would be nice to know the CLI commands as well.

      • Enabling Auto Edge helped… Now I am down to 5 seconds… Any other settings you recommend changing to optimize the switch? Please advise.

    • I’m guessing here that the Admin Edge option (which I had not spotted) might be even better. I interpret Auto-Edge as the switch making a best swipe at whether it’s an edge port or not (presumably based on not seeing a BPDU within a few seconds or something). Admin Edge sounds like the option to manually force it to be an Edge port. Try it – it might be even faster!

      • A quick check seems to confirm that this is the case. The config changes to:

        interface 0/2

        spanning-tree edgeport

        …which looks good. Thanks for finding that!

  9. John,

    Can you provide me the detail instructions on creating a dynamic link aggregation via the web interface and how to test the setup. Additionally it would be nice to know the CLI commands as well.

  10. Has anyone tried to put Indigo on these with success? I managed to brick one and it just powers up with the fans at full speed with nothing on the console. Hoping I can recover it at some point by finding the right pins for a console or link to the flash.

  11. Hi,

    Can someone provide some help on enabling HTTP Admin mode on the Quanta LB4M switch. I can’t access the web interface. I’ve been searching through the serial interface but have yet to find the option to enable it.

    • I don’t think there’s a specific command to enable the web interface. My management set up is using an in-band interface (so is accessed via the regular ethernet ports) and looks like this:

      network protocol none
      network parms
      network mgmt_vlan 255

      (I happen to use vlan255 and trunk to elsewhere for the gateway). You should, I imagine, be able to do something like this:

      network protocol none
      network parms
      network mgmt_vlan 1

      …then plug in to an access port on vlan 1 so access it. If you want to use the mgmt port, that’s the “serviceport”, so your config might look like this (with a static IP again):

      serviceport protocol none
      serviceport ip

      Then plug into the mgmt port. I will tell you that I have had a whole heap of problems with the serviceport, especially if you try and have inband mgmt as well as using the serviceport. If a config like the above won’t get you access on the dedicated mgmt port, you might try going into config mode and try adding the network config I mentioned above and see if you can access it inband instead. Let us know how you get on!

    • You might also want SSH when you’re up and running:

      ip ssh server enable
      ip ssh protocol 2

      And if you are feeling brave and want to disable telnet:

      no ip telnet server enable

  12. This switch consumes 70w which makes them a crime to run in most countries. You are very likely better off getting a less-featured fan-less mikrotik crs226 if tco is a concern.

  13. So that is me in the video.

    The switches all came out of Microsoft Azure and were built with containers filled with C6100 3 node servers by Quanta/Dell. There is a dual PS and single PS version of the switch. I think there is no spanning tree on these so careful connecting both 10GB ports.

    Quanta just announced a new FANLESS 48 port 1G with 4x 10 GB and full OS all L2 and some L3 for about $680 street price. 0 fan and 0 noise for home.

    quanta pn is 1P02ZZZ0003

    I am going to try and re-do the security and wifi networks here around them. we sneak all of that stuff in a cloaset.

    • Nice! Thanks for identifying yourself and sharing that info. The lack of fans would definitely be appreciated, though I should probably ditch my Juniper EX as well for the same reason. Well, and the servers. Gah.

  14. Does anyone have any recomondations for 48x SFP as low price or used model?

    I’d like to give access to all my neighbours, without connecting the houses electricly (lightning safety and stuff)…

    For certain nerd “value” I bought a symetric fiber uplink some years ago… Theres still a lot capacity left, so I could share with them easily.

    Kind regards

  15. Actually LB4m’s command is equal to “NetApp® 10G Cluster-Mode Switch”
    If you seacrh CLI with NetAPP CN1610 by google, you will get what you wnat

  16. How good are these for just being a ‘dumb’ L2 switch? We have an older Dell 2748, but need more ports and the Quanta looks like it might be a good fit on the cheap.

  17. Hi there,
    I’m new with this switch, bought it at the web. Now, I tryed to connect to my LAN. The switch starts up, gets a local IP address, but I cannot access the web interface.
    What I have to do to access it? May you can help?
    Thank you!
    Cheers, Sebastian

    • Hey everybody,

      sorry to warm up this threat but I bought an LB4M on an secondhand-IT-Dealer and have some big problems with the WEG-GUI:
      I configurated
      (network protocol none
      network parms
      network mgmt_vlan 1)
      many times the in-band interface, but it dosen´t work and I can´t open the GUI in my browser. What can I do ?

      thanks for helping,
      and greetings from Hamburg/ Germany

  18. Hi Guys
    The web interface if this switch is very similar to RackSwitch G8124-E which is now Lenovo.
    So to me this is a White box switch/bare metal switch.

  19. Hi,
    just got 8x of the LB4M switches.
    I need to LAG the 2x 10Gbps SPF+ ports to 2x Arista 7050S 52-port SPF+ switches.
    I created the LAG on Arista & LB4M, the LAG came up and no error, but it is not passing any VLAN.
    I set up the VLAN on the LB4M using the GUI.

    Can someone help with this?
    Please & Thanks.
