Enabling and
Disabling Power to
Slots
You can enable or disable power to any slot in your chassis, and the EME
does not turn on power to the module in the disabled slot. Modules in
disabled slots are not allocated power. All slots are enabled by default.
You enable or disable power to slots by entering the
set power mode
command at the EME prompt using the following syntax:
set power slot <slot #> mode enable
set power slot <slot #> mode disable
In the following example, power is enabled to slot 2:
CB9000> set power slot 2 mode enable
Slot 2 enabled
CB9000>
If there is:
■
Sufficient power available to meet the requirements of the new
module, the EME enables power to the specified slot and reduces the
power budget by the amount of power that module consumes.
■
Insufficient power to meet the requirements of the new module, the
module remains in power-pending state until sufficient power
becomes available.
A module that was powered off due to a lack of sufficient available
power is in
power pending state
. The EME automatically powers on the
module again when sufficient power becomes available.
