STK-RPS-1005PS 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 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 power supply ships with the following:
• AC power cable
• RPS cable
• Four rubber feet (for
flat surface installation)
