STK-RPS-1005PS Redundant Power Supply

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 effect 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 STK-RPS-1005PS provides load sharing, backup, or additive PoE power to some Extreme Networks 802.3at PoE-compliant stackable switch models. If the switch loses power from its internal power supply, the STK-RPS-1005PS can provide up to 1005 W maximum operating power (180 W system power and 740 W PoE power) to support switch operation and the 55 VDC necessary to support 55 VDC/data connections to powered devices.

The STK-RPS-1005PS is compatible with the ExtremeSwitching X440-G2-48p-10GE4 switch.
