    Netgear Switches - things I found

    Dear all;

    Just been playing about with some Netgear Switches I bought, they do have 'quirks' lol but I'll try and note down some here in case it helps others (EduGeek has given me massive load of help before)..I will update this thread as I get to grips with the things.

    I have bought GS724TP, GS724TPS, GSM7328S and GSM7328FS

    1) Watch the depth of the GSM724TPS (310mm) add your stacking HDMI cables and Mains Plug it won't fit a lot of my wall cabinets (I had to buy right angled mains plugs)

    2) Firmware updating on the switches isn't the most intuitive, I used the Smartwizard discovery tool to update the firmware I took a while to find out why the switch firmly stuck to the previous firmware version. Turned out I needed to unzip the firmware file first as a .ROS file (my bad - I should RTFM lol) but it seems the Smartwizard utility will upload anything and try to apply without giving a meaningful error message, so keeps you scratching your head with what's gone wrong.

    3) The web browser on the GS724TS / TPS is absolutely atrocious , to the point I was worried about whether I made the wrong choice of switch for my school, it was slow, locked up often and very unresponsive. I later tried Google Chrome (20.0.1132.57 m) and the difference is massive (I was using IE 8-9 before) now the web console is actually usable.

    4) I have read on Netgear Forums that STP (Spanning tree) is on globally by defualt on GS724TP/TPS..which have cause people network slow downs and high switch CPU utilisation , so indeed looking at the GS724TP/TPS I have STP is on by defualt. I have turned off the settings for now.

    Thanks for shareing your experiences, we have a few Netgears around and I have shared some of them:

    1) Yes - have had the same issue, only fit in one of our cabinets, the rest needed spacers and right angled cables. PoE is trouble.

    3) Found the same thing, good to know that a different browser fixes it as it is practiclly unusable in IE which their forums are no help with. Its nice to know that in this age of 'universal access' interfaces that they are still developed to need a specific browser.

    No worries Synack, least I can do.

    One less important Nitpick I have is the GS724TP and GS724TPS looks completely different (presumably from 2 different OEMs)

    Also Version 2 22/07/2012 of things I found:

    1) Watch the depth of the GSM724TPS (310mm) add your stacking HDMI cables and Mains Plug it won't fit a lot of my wall cabinets (I had to buy right angled mains plugs)

    2) Firmware updating on the switches isn't the most intuitive, I used the Smartwizard discovery tool to update the firmware I took a while to find out why the switch firmly stuck to the previous firmware version. Turned out I needed to unzip the firmware file first as a .ROS file (my bad - I should RTFM lol) but it seems the Smartwizard utility will upload anything and try to apply without giving a meaningful error message, so keeps you scratching your head with what's gone wrong.

    3) The web browser on the GS724TS / TPS is absolutely atrocious , to the point I was worried about whether I made the wrong choice of switch for my school, it was slow, locked up often and very unresponsive.

    5) If you have older firmware on your GSM7328FS (8.0.3.15) your AX743 module will not work see thread: Netgear GSM7328FS and AX743 module
    upgrade your Core switch to a later firmware.

    All switch manufacturers seem to be using the same methods for connecting switches @ 10Gbps together using SFP+ modules, HDMI or CX4 on the rear of the switch. I think this is to maintain the highest density possible, but it does mean deeper cabinets are required.

    Also, older HP switches used the IEC C13 power, but newer HP's use the IEC C15. I'm not entirely certain what the difference is other than the shape and the temperature limits.

    What's odd though, is none of the major manufacturers seem to be offering 10GBase-T over CAT6 or CAT7 modules, but only the three options above. I personally use SFP+ modules, as the other two are copper. Fiber's definitely the future, no matter how far they're able to exceed speeds using copper.

    Fiber is always the future, it's always more extendable, electricly isolated and where the bleeding edge is. For really close in links copper is the present though, given its other comercialised uses it is well tested (HDMI) and cheap as anything in comparison. I agree that Fibre is always better from a technology standpoint but cost wise coper always has it won for the extremely short runs.

    I've found that by buying Fiber modules (for the rear of the switch, such as J9008A) and direct attach Fiber cables , the cost isn't that much higher than the copper alternative. It then opens other options to install a second 10GbE SFP+ fiber transceivers, such as the J9150A for longer distances. It's these modules that are considerably more expensive (at the moment)

    Depends on the switches you're dealing with, a lot of the lower end gear has the HDMI variety built right in so your extra cost is very low and included upfront.

    It's funny though, you wouldn't think to use HDMI to connect network switches. Interestingly HDMI 1.0 to 1.2 supports 4.95 Gbit/s, but HDMI 1.3 supports 10.2 Gbit/s according to Wikipedia. It didn't say what HDMI 1.4 supports (if any different). You kind of have to wonder is there any need for USB 3.0 if HDMI 1.3 exceeds it? 5 Gbit/s vs 10.2 Gbit/s. Even FireWire revision 1394d is 6.4Gbit/s, but I don't think I've even seen one of these!

    HDMI v1.4a is 15.2Gb/s. I use a HDMI cable to send audio from my PC to an AV receiver because TOSLink and S/PDIF do not have enough bandwidth for DTS-HD MA/TrueHD.

    USB serves a different purpose so we probably couldn't do without it.

    It's all about the protocols in use, the hardware signaling is digital and can handle different stuff though as when it's used for stacking. Just look at Displayport and the encapsulation of USB and display traffic over it. Also Lightpeek/Thunderbolt and its encapsulation of PCI-E, USB, network etc.

    These exist thanks to different backwards compatibility, product differentiation and patent avoidance, Displayport only exists to avoid HDMI and many different usb connectors exist also to avoid tripping over insane patent laws. We are drifting a tad off topic though sorry OP

    That's ok, and I thought I could plug my Netgear into my Plasma and watch something lol...but being digital, I suppose it can be used for networking, HDMI 1.4a is meant to carry 2x1080p 3D streams as well as HD audio afterall, and that is a hell lot of data..

    Yeah, going to wind down a bit today(ticked off my list the fustrating Firmware upgrade on my Netgear GS724s and also can't upgrade my GSM7328FS firmware to test my AX743 modules till Monday) might read up on VLANs and Access Control Lists tonight. Monday got 4 DL 380 G7s to build, play with my MSA P2000 SAN and mount as many edge switches as I can...only without school kids and teachers can I get any of this done lol!

    Right, after the excitment of the Olympics I've decided to have a little think about the Netgear stuff again:

    Also Version 3 29/07/2012 of things I found:

    1) Watch the depth of the GSM724TPS (310mm) add your stacking HDMI cables and Mains Plug it won't fit a lot of my wall cabinets (I had to buy right angled mains plugs)

    2) Firmware updating on the switches isn't the most intuitive, I used the Smartwizard discovery tool to update the firmware I took a while to find out why the switch firmly stuck to the previous firmware version. Turned out I needed to unzip the firmware file first as a .ROS file (my bad - I should RTFM lol) but it seems the Smartwizard utility will upload anything and try to apply without giving a meaningful error message, so keeps you scratching your head with what's gone wrong.

    3) The web browser on the GS724TS / TPS is absolutely atrocious , to the point I was worried about whether I made the wrong choice of switch for my school, it was slow, locked up often and very unresponsive. I later tried Google Chrome (20.0.1132.57 m) and the difference is massive (I was using IE 8-9 before) now the web console is actually usable.

    4) I have read on Netgear Forums that STP (Spanning tree) is on globally by defualt on GS724TP/TPS..which have caused people network slow downs and high switch CPU utilisation , so indeed looking at the GS724TP/TPS I have STP is on by defualt. I have turned off the settings for now.

    5) If you have older firmware on your GSM7328FS (8.0.3.15) your AX743 module will not work see thread: Netgear GSM7328FS and AX743 module
    upgrade your Core switch to a later firmware.

    6) Gs724TS / GS724TPS have really noisey fans that seem to be stuck and full speed (no speed adjustments in the web management) googling this it looks like they take standard 40mm fans and standard power headers so will look at trying some Scythe Mini-Kaze Ultra (SY124020L) to test. Although they don't output as much airflow as stock fans.

    7) Management Console on GSM7328s : Any changes you make needs to be saved (Maintenance>Save Configuration) although it does prompt you when you revoke a reboot, if there is a powercut or you just pull the plug it will lose all your current changes.
