localzuk Posted July 26, 2007 Posted July 26, 2007 Just some warning for anyone planning on buying one of these switches (they differ from the normal 2626 as they have PoE on every port)... They are huge!!! Even bigger than a 2650!! I have been very lucky that the cabinet it has gone in is mounted to some blocks of wood before being mounted to the wall. I haven't measured it yet, but be ye warned!!
Geoff Posted July 26, 2007 Posted July 26, 2007 Yes, the PWR series are 48.3cm (19 inch) deep as apoosed to the 2650's 43cm (16.9 inch). Also remember the PWR switches throw about 3x as much heat as the non-PWR switches when unloaded. When all ports are loaded, this increases to over x10. I highly recommend you monitor and adequately cool/ventilate your cabinets if your using PoE switches.
localzuk Posted July 26, 2007 Author Posted July 26, 2007 I just have the one of these, in a well ventilated room. I shall be monitoring it closely though!! Also, I will only actually be using 10 of the ports as PoE at the moment, the rest will be empty.
Geoff Posted July 26, 2007 Posted July 26, 2007 Good. It would be a shame to have your new switch melt
DMcCoy Posted July 26, 2007 Posted July 26, 2007 I have a 5412 with 6 PoE modules. Only have two of the little PSU modules at the moment though, although it needs both to turn the 10Gb module on due to the number of used slots, the fibre being the last. Room has air con and there will only be a few PoE ports used for wifi, the bunde comes with them all as PoE anyway.
tom_newton Posted July 26, 2007 Posted July 26, 2007 I have had one of those (think its a 2626... too far to walk across and check) with 12 IP phones taaking PoE, and without air-con the server room hits 34C. I didnt notice it as being particularly huge when I installed it, but hot and noisy it certainmly is.
DrFrankenMouse Posted July 26, 2007 Posted July 26, 2007 Yes, the PWR series are 48.3cm (19 inch) deep as apoosed to the 2650's 43cm (16.9 inch). And which joker at HP had the bright idea of putting the console port at the back :angryfire:

And which joker at HP had the bright idea of putting the console port at the back :angryfire: Here here! That was my main problem. That console cable added an hour to my install time as I had to move the supporting joists in the cabinet forward to fit this monstrosity in. And with all that spare front panel space it would make sense to have at the front!
john Posted July 26, 2007 Posted July 26, 2007 Yes, the PWR series are 48.3cm (19 inch) deep as apoosed to the 2650's 43cm (16.9 inch). And which joker at HP had the bright idea of putting the console port at the back :angryfire: Hate to say it, but you should have bought Netgear, they are now moving a alot to the front panel to make it easier
localzuk Posted July 26, 2007 Author Posted July 26, 2007 Ah, but netgear aren't anywhere near as good...
Geoff Posted July 26, 2007 Posted July 26, 2007 Yes, the PWR series are 48.3cm (19 inch) deep as apoosed to the 2650's 43cm (16.9 inch). And which joker at HP had the bright idea of putting the console port at the back :angryfire: Err, your supposed to configure it *then* put it in the rack.
john Posted July 26, 2007 Posted July 26, 2007 Ah, but netgear aren't anywhere near as good...I have not had any issues with my Netgear Kit, the ProSafe kit is all very good kit and I am very happy with it.
Oops_my_bad Posted July 26, 2007 Posted July 26, 2007 Only issue we have had with most of our prosafe stuff is blown ports 8O And having to get our heads around the weird VLAN terminology (different to cisco/HP apparently)
john Posted July 26, 2007 Posted July 26, 2007 Hmm mine's all been good, but they now have lifetime warranty so if they die you get them changed, just like the HP ones.
DrFrankenMouse Posted July 26, 2007 Posted July 26, 2007 Err, your supposed to configure it *then* put it in the rack. Well I kind of figured that's what I had to do but the manufacurers instruction gave the opposite impression. Mounting switch (i.e placing it in a 'telco' rack) is step 4 , whereas connect a console to switch is step 8. HP seem to think its OK to connect devices to the switch before configuring it. Infact the configuration is said to be 'optional'. As for me, I just wanted to get it in the cabinet ASAP then configure and then attach devices. So why, when all other managed switches have front facing ports, does 2600 series have ones at the back? Re-grrrr It needlessly lengthens the profile of the switch as you have to keep the serial lead connected permanently cos there's no way you can just attach and detach as and when you need like with other switches. Maybe some people are lucky enough to have cabinets with 360 access Sorry I'll carm down now.
DMcCoy Posted July 26, 2007 Posted July 26, 2007 They do automatically get an ip address though. I rarely have to configure any edge ones with the serial cable.
Oops_my_bad Posted August 2, 2007 Posted August 2, 2007 Hmm mine's all been good, but they now have lifetime warranty so if they die you get them changed, just like the HP ones. interesting... do you know if that covers prosafe stuff you bought *before* the lifetime guarantee came into effect?
