In a mixed stack with Catalyst 3750-X and 3750-E switches, one or more Catalyst 3750-E switches can
be connected to a Cisco Redundant Power System 2300, also known as the RPS 2300. You can use the
power rps command to configure and manage an RPS 2300 connected to a Catalyst 3750-E switch.
The RPS name is a 16-character maximum character string. In a standalone switch, the name applies to
the connected redundant power system. In a switch stack, the name applies to the redundant power
system ports connected to the specified switch. For example, if a stack of nine switches is connected to
three redundant power systems and you enter the power rps 1 name "abc" command, the name of the
redundant power system connected to switch 1 is abc, and the names of the other redundant power
systems are not changed.
If you do not want the RPS to provide power to a switch connected to the specified RPS port but do not
want to disconnect the RPS cable between the switch and the redundant power system, use the power
rps switch-number port rps-port-id mode standby command.
You can configure the RPS port priority from 1 to 6. Specifying a value of 1 assigns the port and its
connected devices the highest priority and specifying a value of 6 assigns the port and its connected
devices the lowest priority. If multiple switches connected to the RPS need power, it provides power to
the switches with the highest priority. If the RPS still has power available, it can then provide power to
the switches with lower priorities.
The no power rps user EXEC command is not supported. To return to the default settings, use these
commands:
•
To return to the default name setting (no name is configured), use the power rps switch-number port
rps-port-id name global configuration command with no space between the quotation marks.
•
To return to the default RPS port mode, use the power rps switch-number port rps-port-id active
command.
•
To return to the default RPS port priority, use the power rps switch-number port rps-port-id
priority command.
This example shows how to configure the name of the RPS 2300 that is connected to a switch as the serial
number:
Switch> power rps name serialnumber
This example shows how to configure the mode of RPS port 1 as standby on a switch:
Switch> power rps port 1 mode standby
This example shows how to configure the priority of RPS port 3 with a priority value of 4 on a switch:
Switch> power rps 1 port 3 priority 4
You can verify your settings by entering the show env power or the show env rps privileged EXEC
command.
