RPS-500p Redundant Power Supply
Tip
Extreme Redundant Power Supplies (RPS) do not support the ability for the RPS to be
connected to an operational switch. Connecting an RPS to an operational switch can have an
adverse eect on the switch. It is best practice that both the switch and the RPS be powered
down prior to cabling them together. Once the cabling is completed, turn on the RPS, then
turn on the switch.
The RPS-500p (model 10923) is a 500 watt DC power redundant power supply for use with Extreme
802.3at PoE-compliant stackable or standalone switches. The RPS-500p is a standalone unit that can
be rack mounted in a standard 19-inch rack.
The power supply provides power backup to an Extreme stackable or standalone fixed switch. If for
some reason the switch loses power from its internal power supply, the RPS-500p can provide up to
500 watts maximum operating power to support switch operation and the 55 VDC necessary to
support 55 VDC/data connections to PDs (powered devices). The RPS-500p has one 2x7 power
connector.
