    Indeed, I have 4 Finisar ones (who I believe manufacture the branded ones for HP) but recent firmware updates have meant they are just gatherering dust on the spares shelf.

    Thats my choice though and you may chose differenty
    My thoughts exactly. I've never seen an HP unit fail, but have seen netgear ones go up in smoke (literally), seen d-link ones do strange and not-so wonderful things, and 3com ones have just been a complete disaster to me. I've never had problems with Cisco though.

    They don't come with any in, so you'd have to buy one or 2 - I'd go for 2, to provide redundancy in the key part of your network.

    Thank you all for your help with this been great help. I know the bursar will die of shock when he see's the figures but i think it will be a good move in the long run.

    Just as a side note we've only had 3 netgear switches fail in 8 years and all have been replaced under warrenty but i'm starting to see some slow down on the 5 year old main switches so now is a good time to replace before they fail one busy coursework deadline day.

    We have a complete Netgear network (FE doesn't have the cash which has been thrown at secondary schools :-))

    We have had a few failures but warranty replacement has been good. The layer 3 switches are relatively cheap so we just have spares sitting in the racks at key points, ready configured so that if a switch does fail we can just swap over to the spare.

    I think everyone can tell horror stories about a brand - I've seen a stack of 3Com switches go up in smoke one after the other, for example - but it would be good to get genuine technical reasons for buying another platform.

    as mentionmed above - 3com suck too! As for genuine technical reasons - would be nice but real world experience will do for me!

    J8702A Procurve 24-port 10/100/1000PoE Module x3
    J8706A Procurve 24-port Mini-GBIC module x1
    J4858C Procurve Mini-GBIC x20
    J8712A Procurve 875W power supply x2
    J4899C Procurve 48-port Switch x8

    Our whole network is now 3com, including wireless points. We also install 3com in some of our primary schools. The only issue we've had with 3com is when lightning hit the building and blew random ports on some of the switches (which i'm fairly sure would happen with all makes of switch :P). Also, one of the antenna for a wireless access point didnt fit on it, but they replaced that fairly quickly.

    We've been quite lucky with cisco kit over the years, although we recently had a very old 3500XL stackable switch die after being unplugged and removed from the equipment rack.

    The 3500XL's don't have line cards just a couple of GBIC slots. When we plugged it back into the switch stack the tell tale lights that indicate a faulty switch came on......on further inspection, error codes pointed to ESD damage to one of the internal components.

    What's odd is that you can't get to any internal cicrcuitry without pulling the cover off......and that's never been done. improper insertion and removal of gbics would cause ESD damage to the gbics only.

    Very bizarre occurance as wouldn't have thought you'd need to take ESD precaustions for handling the switch itself. Dust could have been an issue as it was caked in it....but other than that i can't believe ESD damage from handling was to blame - but then the fault only occured after it was removed so there you go. There are some switches that have an ESD point for attaching anti-static wrist strap, but not the 3500XL.

    My advice is to take care when handling whatever switch TS chooses to buy.

    Is it worth adding Procurve Manager Plus to the mix or is the free Manager version ok?

    Depends if you prefer to do things via the console or via a nice GUI. I bought the full version but then the license details went missing before I could set it up. I've managed just fine without it really.

    Yes, the console is easy enough. Especially when you have a TFTP server and can have your switches TFTP their configs to themselves.

    Out of interest what's the difference between the 2650 and the 2610 \ 2810 switches, as far as I can tell the 2650 and 2626 seem to be the older models and the newer replacements are the 2610 \ 2810 (which if you have the 24 port models are fanless )
