ports 16–31 with an FC4-48, the FC4-48 faults. To correct this, reinsert the FC4-32 and issue
portSwap
to restore the original area IDs to ports 16–31.
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.
NOTE: 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.
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 54 includes CP and port blade abbreviations and
descriptions.
