    New Core Switch

    Our current core switch is dead/dying

    I am looking at getting a new HP Procurve modula switch to replace it.

    I am looking at getting the 4208vl switch, 4 J9033A modules and these mini gbics MGBLX1.

    Is anyone currently using this switch?
    Is there are good or bad points I need to look out for?
    Is there anything I can look at for a comparison?

    If there is anyone that has got one and wouldn't mind me having a look in the Bexleyheath, Dartford area that would be brilliant.

    Thanks in advance

    I've never tried using anyone elses, but HP's paper work very clearly states that you must use HP mini gbics.

    As for HP stuff, we've got loads of it. Doesn't give very many issues, although we have had 2 POE switches die recently.

    EDIT: Just checked, the mini gbics I'm using are J4858C

    You must buy HP mini-gbics, other ones won't work. Also be careful if uou're tempted to pick the up second hand, as the older revisions of the HP ones don't work either!
    What size network have you got and how many switches you going to be connecting to this? Also, are you going to be using VLANS and if so would this also act as the router?

    I have this exact model. It's alright, but it is NOT a routing switch. It is really little more than an edge switch on steroids. If I had my way, I would replace it with something in the 5000 series. No money in the budget for that, however.

    Rather than trying to spec this up yourself, I would strongly recommend you put together a little document of what you want to do with your core switch, size of network etc and get a few HP Procurve resellers, or even HP direct to specify exactly what you need. Get this in writing, as once I got a verbal spec off HP, ordered through a reseller and found some of the modules were wrong. As I had no documentary evidence that HP had mis-specified we had to take quite a hit on a re-stocking fee as we didn't realise until we'd opened the packaging.

    Thanks for al the advice so far.

    We don't use vlans but may do in the future.

    We currently have 3com switches with CISCO gbic converters. We will be connecting to 12 other switches via fibre but want room to expand. I have just had a look at the HP mini-gbic 1000base-LX and they are between £300 - £500 which is alot more that the one I was looking at.

    I did look at the 5000 series but the modules are £2,000 compared to the £700 for the 4000 series.

    I may have to look at other options to keep the cost down but I think modula switches are the way to go.

    Don't go off advertised price for this stuff, go to an HP Procurve main partner and they will get you education pricing, which is a lot better. Even after that, haggle ;-)

    Any specific reason for using LX rather than SX gbics?

    I have a 5406. The modules are expensive but They cram in a lot of ports. I didn't particularly need a 24 port GBIC module but at least I can say there is plenty room for expansion

    Just payed just over £1700 for a 24port gigabit power other ethernet module and you can get some decent bidding pricing for those switches from HP resellers usually.

    We've got one, not using routing at the minute, but it's an excellent switch. The one thing that irks me is you have to have POE which when twinned with gigabit is fairly expensive feature. I'm sure they could make a non POE version much cheaper if they wanted.

    3Com have been bought out by HP, 3Com as such no longer exists. Most of their switches have been rebranded as HP, some discontinued.

    I think what'd help is an indication of how many edge switches you'll be connecting, amount of machines on the network etc... ie. give us a sense of scale to work with.

    We have a 5406zl here and it works flawlessly, including routing.

    Also, as mentioned, it may be worth your while to switch to SX gbics, as they cost a fair amount less - it may work out cheaper to buy SX Gbics, and new fibre media converters.
