SPECIFICATIONS
(CONTINUED)
3Com has tested and qualified a Redundant Power System (RPS) solution
designed for the Switch 5500G family by Eaton Powerware Corporation,
a leading global provider of power quality and management solutions.
The Powerware DC RPS systems come in either 3RU or 6RU form-factors,
delivering up to 9,000W of DC power to a stack of Switch 5500G 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 fully compatible
with the IEEE 802.3af Power over Ethernet standard, providing supple-
mental 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. For more details, refer to
