Configuring the Savepower LED Option

The savepower LED option provides the ability to configure a timer for turning off the chassis LEDs as well as the configured slot LEDs.There is one systemwide timer; all the selected slots will have the chassis LEDs turned off for the same amount of time.

Syntax: [no] savepower led [slot-id] < MM/DD[/[YY]YY] <HH:MM> now > duration [HH:<MM> [recur]

Schedules a timer for turning off the chassis LEDs and config­ ured slot LEDs. The LEDs are turned off for the configured time period and duration.

If a slot is specified, the LEDs for that slot are turned off. This is enabled by the timer command, however, if a timer is already running, the feature is enabled immediately.

The all option can be specified for the slot-id. All the switch

LEDs are turned off.

<MM/DD[/[YY]YY] <HH:MM>>: Specifies the date and time to start the timer.

now: Instantaneously turns off the LEDs. The configured timer is canceled and all the configured modules go into power-saving mode immediately.
