After the power-supply led-blink command is executed, the LED of the corresponding power supply
blinks for a period of time to show you the location of the power supply. You can configure the time when
the LED blinks and how long the LED keeps blinking. If you execute the command without specifying the
power supply ID, the LEDs of all power supplies blink one by one in the ascending order of the power
supply IDs.
After you allocate IDs to the AC power supplies, and reboot the switch after a period of time, the
following rules apply:
• If the locations of the AC power supplies do not change or some AC power supplies are removed
during this period of time, the IDs of the AC power supplies do not change after the switch reboots;
• If the locations of the AC power supplies are changed or some new AC power supplies are installed
during this period of time, the AC power supplies are allocated new IDs randomly after the switch
reboots.
To allocate IDs for AC power supplies:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the time when the
LED of the specified power
supply blinks and how long
the LED keeps blinking.
• In standalone mode:
power-supply led-blink
[ module id ] [ blink-time value ]
[ delay-time value ]
• In IRF mode:
power-supply led-blink chassis
chassis-number [ module id ]
[ blink-time value ] [ delay-time
value ]
Optional.
Use either command.
By default, the LED blinks for 3
seconds as soon as the command
is executed.
3. Allocate new IDs for the
specified AC power supplies.
• In standalone mode:
power-supply module old-id-list
new-id new-id-list
• In IRF mode:
power-supply module chassis
chassis-number old-id-list
new-id new-id-list
Use either command.
By default, the system allocates IDs
for AC power supplies randomly.
Each AC power supply can be
allocated with only one ID, but
different AC power supplies
cannot have the same ID.
