Hi all,
Voice over IP (VoIP) is a technology being considered where I work (a
University). We have a very large network with Cat5 outlets for data
and voice, but the voice is patched back to a regular telephone system.
It would be nice to be able to connect all Cat5 outlets into an
PoE-capable Ethernet switch, then simply configure each port to the
voice or data VLAN. However, there are some issues that I'd like your
opinions on. If a typical wiring closet has 192 outlets (and our
network has LOTS of closets), and these are all patched into a PoE
switch stack, then that equates to about 6KW of power requirements
(rough figures from various sites). Does this mean
- I need to route a major power supply to the wiring closet?
- I need a colossal UPS to provide a decent amount of runtime? (By the
way, regular phone systems are protected by UPSes. Anyone know how
long they are meant to run in the UK? I'm assuming there's some kind of
regulation)
- That much power is going to generate a lot of heat. Do I need air
conditioning, which itself must be protected by the UPS?
- That much power represents a fire risk(?) - do I need a fire
suppression system?
Suddenly a humble wiring closet needs the kind of very expensive
environment previously reserved for server rooms.
Any opinions greatly appreciated.
Kind regards,
Anwar
