Configuring the Cisco Redundant Power System 2300

	Command	Purpose
Step 4
	system mtu bytes	(Optional) In a mixed hardware stack, change the MTU
		size for all Fast Ethernet interfaces on the Catalyst 3750
		members.
		The range is 1500 to 1998 bytes; the default is
		1500 bytes.
		Note This command does not apply to
		Catalyst 3560-E switches.
Step 5
	end	Return to privileged EXEC mode.
Step 6
	copy running-config startup-config	Save your entries in the configuration file.
Step 7
	reload	Reload the operating system.
Step 8
	show system mtu	Verify your settings.

If you enter a value that is outside the allowed range for the specific type of interface, the value is not accepted.

This example shows how to set the maximum packet size for a Gigabit Ethernet port to 7500 bytes:

Switch(config)# system jumbo mtu 7500

Switch(config)# exit

Switch# reload

This example shows the response when you try to set Gigabit Ethernet interfaces to an out-of-range number:

Switch(config)# system mtu jumbo 25000

Configuring the Cisco Redundant Power System 2300

You can configure and manage the Cisco Redundant Power System 2300, also known as the RPS 2300.

Note The Catalyst 3750 and 3560 switches do not support the power rps user EXEC command. You cannot configure the redundant power system (RPS) name, RPS port name, or RPS port priority on these switches.

Follow these guidelines:

•The RPS name is a 16-character-maximum string.

•On a Catalyst 3560-E or a standalone Catalyst 3750-E switch, the RPS name applies to the connected RPS 2300.

•In a switch stack, the RPS name applies to the RPS ports connected to the specified switch.

•If you do not want the RPS 2300 to provide power to a switch, but do not want to disconnect the RPS cable between the switch and the RPS 2300, use the power rps switch-numberport rps-port-idmode standby user EXEC command.
