Warning
Attach only the following Cisco RPS model to the RPS receptacle: RPS2300. Statement 370
Connect the switch and the redundant power system to different AC power sources.
Use the CAB-RPS2300-E cable for the RPS.
Cisco RPS 2300
Cisco RPS 2300 is a redundant power system that can support six external network devices and provide
power to one or two failed devices at a time. It senses when the internal power supply of a connected
device fails and provides power to the failed device, preventing loss of network traffic. For more
information, see the
Cisco Redundant Power System 2300 Hardware Installation Guide
http://www.cisco.com/en/US/products/ps7148/prod_installation_guides_list.html
The Cisco RPS 2300 has two output levels, 52 V and 12 V, with a total maximum output power of 2300
W.
All supported and connected switches can simultaneously communicate with the RPS 2300. You can
configure these RPS 2300 features through the switch software:
•
Enable RPS active or standby mode for each connected switch
•
Configure switch priority for RPS support
•
List the connected switches and the power supply module sizes
•
Obtain reports when a switch is powered by the RPS
•
Obtain status reports for the RPS power supply module
•
Read and monitor backup, failure, and exception history
Fan Modules
The switch has three internal hot-swappable 12-V fan modules. The air circulation system consists of
the fan modules and the power supply modules. The airflow patterns vary depending on the power supply
configuration.
shows the airflow patterns for the 24-port and 48-port switches. The blue arrow shows cool
air flow, and the red arrow shows warm air flow. When the fan modules are operating properly, a green
LED is on at the top left corner of the fan assembly (viewed from the rear). If the fan fails, the LED turns
to amber. The switch can operate with two operational fans, but the failed fan should be replaced as soon
as possible to avoid a service interruption due to a second fan fault.
Note
Three fans are required for proper cooling.
