Redundant With Reboot
If the Cisco RPS fails or is disconnected, the external device will not power cycle because
its internal power supply has not been disturbed. When both the Cisco RPS and internal
power supply are powered, the LED on the Cisco RPS front panel and the RPS LED on the
external device both blink green.
If you cannot afford the 30-second interruption, unplug the external device AC power cord
and use only the Cisco RPS with the Y-cable. There is no downtime when using the
Cisco RPS with the Y-cable.
