REDUNDANT POWER
SYSTEM
3Com has tested and qualified a Redundant Power System (RPS) solution designed for the Switch 5500 family
by Eaton Powerware Corporation, a leading global provider of power quality and management solutions.
The P
o
werware DC RPS systems come in either 3RU or 6RU form-factors, delivering up to 9,000W of DC power
to a stack of Switch 5500 units. The 3RU RPS unit houses up to three hot-swappable rectifiers supplying up to
4,500W of power that supports up to eight separately-fused DC outputs, while the 6RU unit can house up to
six hot-swappable rectifiers provisioning a total of 9,000W.
The RPS supports SNMP management, including MIB II, which is easily accessible through the built-in
RJ-45 or serial port. It is full
y compatible with the IEEE 802.3af Power over Ethernet standard, providing
supplemental power for the 3Com Switch 5500G PWR models.
With this RPS, all 384 10/100/1000 ports on a stack of eight Switch 5500G PWR 48-port units can receive
the industry standard 15.4W of power per port, with N+1 power redundancy.
The RPS ships with the power input fully configured and can be connected to a UPS with battery backup.
