RPS-500p Redundant Power Supply
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.
The power supply ships with the following:
•
AC power cord
•
RPS cable (1 meter long)
•
Four rubber feet (for flat surface installation)
•
Two rack mount brackets
•
Eight flathead screws (M3x6mm)

•
Summit X440 switches (all models that are compatible with external power supplies)
•
ExtremeSwitching X440-G2 switches (most models)
•
Summit X450-G2 switches (non-PoE models)
The RPS-500p is compatible with both PoE and non-PoE switches.
The RPS-500p is compatible with the following Extreme Networks switches:
•
ExtremeSwitching 220-24p-10GE2 switch
