hw-module beacon
Note The hw-module beacon command is enabled only on the uplink modules of the WS-C4500X-32.
To control the beacon LED in conjunction with the beacon button, enter the hw-module beacon
command:
hw-module beacon [on | off]
Syntax Description
Defaults none
Command Modes global configuration
Command History
Usage Guidelines Either press the beacon button on the front side of the switch or enter the hw-mod beacon command, so the
switch is identifiable when the operator walks around the isle to the back side of the switch. (The LED and
the CLI function as switch identifiers when multiple units are present.)
Pressing the blue beacon LED switch toggles the beacon LED state.
Examples If numerous WS-C4500X-32 chassis are in close proximity and you want to remove a transceiver from
one chassis’ port 11, you can identify it with the hw-module beacon on command:
Switch# hw-module beacon on
Switch#
*Feb 16 13:12:24.418: %C4K_IOSMODPORTMAN-6-BEACONTURNEDON: Beacon has been turned on
The WS-C4500X-32 whose beacon was turned on is the switch you are looking for.
After you complete the necessary service on a switch with the beacon LED turned on, you should either
press the beacon button to turn it off, or enter the hw-module beacon off command to turn the LED off.
Switch# hw-module beacon off
Switch#
*Feb 16 13:12:18.083: %C4K_IOSMODPORTMAN-6-BEACONTURNEDOFF: Beacon has been turned off
on Turns on the LED.
off Turns off the LED.
