Confused about 3Com POE switch
We recently had a new IT build that was completely out of our control and we had little say over the back end kit that was supplied. Needless to say we usually do all the procurement ourselves and it all works but this time it was done for us the the LEA and we've had all sorts of problems.
The one thing I need clarification on it the switch situation they've left us in.
We had supplied 2 x 3COM 5500G-EI (3CR17255-91) 48 port and 24 port and on the front they say POE. The problem is we cannot get POE enabled at all on any ports.
When we go to the console it and use the POE link it tells us "POE is not supported on the equipment or the port".
A quick look at the manual indicates that we might need a separate module to make POE work but I'm a bit unsure on this and cannot find a definitive answer. Some sites say that the POE only needs an add in if the existing POE devices are drawing too much power and I can't find the part number to check (the manual lists some numbers but when searched for they do not appear to be what I want but could be this).
I have managed to get POE working by adding one of our own switches to the cab but this has to be put back soon and I need the supplied ones to work.
Hope you guys can shed some light on this.
