Redundant Power System LED
The Redundant Power System (RPS) LED shows the RPS status (Ta ble 3-2 ). Certain switches in the
switch cluster use a specific RPS model:
•Cisco RPS 300 (model PWR300-AC-RPS-N1)—Catalyst 2900 LRE XL, Catalyst 2950,
Catalyst 3524-PWR XL, and Catalyst 3550 switches
•Cisco RPS 60 0 (mo del PWR600-AC-RPS) —Catal yst 2900 XL and Catalyst 3500 XL switches,
except the Catalyst 2900 LRE XL and Catalyst 3524-PWR XL switches
Refer to the appropriate switch hardware documentation for RPS descr ipti ons specif ic for t he s wit ch.

The RPS could be in standby mode. To put the RPS in Active mode, press the Standby/Active button on the
RPS, and the LED should turn green. If it does not, one of these conditions could exist:
•One of the RPS power supplies could be down. Contact Cisco Systems.
•The RPS fan could have failed. Contact Cisco Systems.
