Conserving Power
To conserve power and ensure that more critical components are the least affected by a power
fluctuation, you can power off components in a specified order, using the powerOffListSet command.
The available power is compared to the power demand to determine if there is enough power to operate.
If there is less power available than the demand, the power-off list is processed until there is enough
power for operation. By default, the processing proceeds from slot 1 to the last slot in the chassis. As
power becomes available, slots are powered up in the reverse order.
The powerOffListShow command displays the power off order.
Blade Terminology and Compatibility
Before configuring a chassis, familiarize yourself with the director CP blade and port blade
nomenclature, as well as the port blade compatibilities. Often in procedures, only the abbreviated names
for CP and port blades are used (for example, the FC4-16 blade). Table 5-1 includes CP and port blade
abbreviations and descriptions.

Some FRUs in the chassis may use significant power, yet cannot be powered off through software. For
example, a missing blower FRU may change the power computation enough to affect how many slots
can be powered up.
