RPS Connector on the Catalyst 2912 XL, 2924C XL, 2924 XL, 2924MF XL, and 2924M XL Switches
The Cisco RPS 600 (model PWR600-AC-RPS) provides a quasi-redundant power
source for four external devices that use up to 150W DC each. Use a one-to-one
cable (one connector at each cable end) to connect four external devices to the
four DC output power modules. The power source is quasi-redundant because
there are two AC input power modules for the Cisco RPS and one DC output
power module for each external device. The AC input to the Cisco RPS is fully
redundant, but the DC output to the external devices is not.
Warning
Attach only the Cisco RPS (model PWR600-AC-RPS) to the RPS 600
receptacle.
Note
Do not connect the switch power cord to an AC outlet if the switch is also
connected to a powered-on RPS. The switches do not support the
fully-redundant configuration described in the RPS documentation. The
redundant-with-reboot configuration is not recommended.
For more information on the Cisco RPS 600, refer to the Cisco Redundant Power
System Hardware Installation Guide.
RPS Connector on the Catalyst 2912 LRE and 2924 LRE XL Switches
The RPS is a 300W redundant power system that can support six external network
devices and provides power to one failed device at a time. It automatically senses
when the power supply of a connected device fails and provides the necessary
power to the failed device to prevent loss of network traffic. When the device
internal power supply has been brought up or replaced, the RPS automatically
stops powering the device.
Warning
Attach only the Cisco RPS (model PWR300-AC-RPS-N1) to the RPS 300
receptacle.
