Configuring Directors

If a previously configured FR4-18i blade is removed and another or the same FR4-18i blade is inserted into

the same slot, then the ports use the previous configuration and come up enabled.

If a previously-configured FR4-18i blade is removed and an FC4-48, FC4-32, FC4-16, FC8-48, FC8-32,

FC8-16, or FC10-6 blade is plugged in, then—other than the port’s EX_Port configuration—all the

remaining port configurations previously applied to the FR4-18i FC_Ports can be used. The EX_Port

configuration on those ports is disabled before the FC4 or FC8 port blade becomes operational. When a

blade is present in the slot, then any requested port configuration is validated against the blade’s

capabilities before accepting the request.

To summarize:

•

When an FC4-16, FC4-32, FC8-16, FC8-32, FC10-6, or FC4-16IP blade is replaced by an FR4-18i

blade, the FC configuration of the previously configured FC_Ports continues to be used, and all

FC_Ports on the FR4-18i blade are persistently disabled.

•

When an FR4-18i blade is replaced by an FC4-16, FC4-32, FC8-16, FC8-32, or FC10-6 blade, then the

EX_Port configuration is removed from any ports that were configured as EX_Ports (equivalent to

disabling the EX_Port configuration using the

portCfgEXPort

command). All remaining port

configurations are retained.

FC4-48 and FC8-48 blade exceptions

The FC4-48 blade is compatible only with the CP4 processor blade, FC4-16/32 port blade,

FR4-18i, and FC4-16IP iSCSI blade.

Because the area IDs are shared with different port IDs, the FC4-48 and FC8-48 blades support only F, G

and E_Ports. They do not support FL_Ports.

Port swapping on an FC4-48 or FC8-48 is supported only on ports 0–15. For the FC4-32 and FC8-32

blades, port swapping is supported on all 32 ports. This means that if you replace a 32-port blade where

a port has been swapped on ports 16–31 with a 48-port blade, the 48-port blade faults. To correct this,

reinsert the 32-port blade 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.
