    Require New Switches

    I've had the network audited for free by the LA IT team and they have recommended that I upgrade all our switches as they're now hitting 8+ years. That, and they don't support IPv6 and whole host of other new features you might get in todays switches.

    My current switches are 3Com Switch 3300SM Super Stack (with a fibre connection) and 3300 (without fibre connections), and are daisy chained. This is located in 2 locations. The 3rd location is just a single 3300SM Super Stack switch.

    My only problem I can foresee is getting in the right switches that will work with our current fibres.

    From what I can see the connections we have is this:

    From patch panel
    File:LC-optical-fiber-connector-hdr-0a.jpg - Wikipedia, the free encyclopedia


    To Switch
    File:MTRJ-optical-fiber-connector-hdr-0a.jpg - Wikipedia, the free encyclopedia


    So, on that basis, what switches do you guys recommend? Everyone says HP ProCurves but nobody states which model or whether I should get them managed or unamanged. Any ideas?

    Not sure of the exact models etc but I personally would always look at the HP ProCurve range. Cracking management software along with a lifetime guarantee, superb stuff!

    You can convert the connectors from your patch panel to the mini gbit on a new switch by changing the patch lead so that's no biggy really.

    Not a real need to worry about ipv6 atm though I wouldnt have thought.

    Can you give us an idea of number of ports in each location?

    Regarding the fibre, that shouldn't be an issue, as LC is pretty much standard and is what is used by the SFP modules used in most switches now, so you'd just need new patch leads (you'll need to know what type of fibre you've got).

    For models, I'd be looking at putting in gigabit switches now - so 5406zl switches where you've got high densities of ports (48+), and 2910s where you need up to 48 port density. You then only need the SFP modules to plug in the fibres. This will allow you to use your existing fibres (which I am going to guess are OM1 type). It also allows you to think about replacing your fibres with OM3 and then utilise 10Gbit backbones between switches.

    I don't know, if his existing switching gear is 8 years old, that gives an idea of the life expectancy of the new stuff, and can you say that ipv6 won't be important in the next 8 years?

    Agree with HP Procurve....I have 5406 at the core, and combinations of 4204/4208 and 2810 24/48 at the edge....

    Make sure you get Routing + and all the bells and whistles in the config. Also, use the bundling options for the 5400 and 4200 series....

    In first location (the core) I have 120 ports but could do with more as some classes don't require a connection yet, even though they already have network points in them.
    Second location is, again, 120 ports and could possibly do with some more.
    Third location is only a 24 port and this is enough as that part of the building only has 20 network points.

    Cabling is Cat 6 but how do I go about finding what type of fibre cables I have in place?

    Is it recommended to go for the HP 5406zl as the core and in other locations go for something like 2910? I'm think 2 x 5406-zl (1st and 2nd location) and a 2910 for the 3rd location. What do you think?

    Can I remote manage the HP switches through the web interface or do the switches require some sort of HP's management software?

    You can get up to 140 network ports on a 5406zl (if you want 1gbit fibre connections anyway - this is done by having 5x 24 port modules and 1 20 port module with 4 SFP slots). Or 120 if you want 10Gbit fibre, done by having 5 x 24 port modules and 1 x 10Gbit module. If you want extra expansion space, you could go for a 5412zl, which can give you upto 284 ports (1gbit fibre) or 264 ports with 10Gbit fibre. (Same as above, just add 6 more 24 port modules).

    The way to find out what type of fibre you have is to look on the patch leads and read what the fibre size is. It'll say something like 50/125 62.5/125 or something like that on it.

    I'd say your plan is fine, unless you want a bit more expansion capability, in which case go for 5412zl's instead.

    You can remote manage them via the web interface (although this doesn't allow full capabilities to manage them), via the CLI (ie. telnet into them) which gives full capabilities, or via HPs Procurve Manager software (which costs extra for full capabilities).

    What kind of budget do you have?! I think ProCurves would be my first choice. I've come in to a school with Allied Telesis GS950's mostly and already had a power supply failure on one. Had to send it back to get repaired. Very lucky as it only had a 2yr warranty which is rubbish in my opinion. Web browser interface management is fairly good though.

    Cisco switches - too expensive!! but HP stuff is really good although I've not had any experience with any really - my favorite switches are Nortel Switches - they are fairly cheap too - the 5500 range are of excellent quality, we have one at the college with a 3 year uptime

    Cheers Localzuk! The fibre size is 50/125.

    Can I use my current patch leads for the HP switches or would I need to purchase new ones? If so, what sort of patch leads would I need to look for?

    What switches are required to populate the HP 5406? And is it possible you could show me a link of what the 20 port module with 4 SFP slots looks like?

    I'm guessing the management software isn't cheap, right? *gulps*

    Interesting, 50/125 is either OM2 or OM3.

    Patch leads - you'll need new ones (rated 50/125), as you'll need to go from LC - LC rather than LC - MTRJ.

    All the different modules can be looked at here - HP E5400 zl Switch Series - Accessories, supplies & services

    It also looks like they've added a 20/2 port 10gbit module too.

    The management software depends on the number of switches to manage - 50 devices is about a grand IIRC.

    The fibre was put in place approx. 6 years ago.

    In the 10gbit module would I connect my servers into it as well (if I had fibre NICs) as well as the other fibre connections from different locations?

    You could put your servers on 10Gbit, yes. However, on an individual server, you're unlikely to need that. Gigabit copper, or a couple of gigabit copper ports trunked would do the job fine.
