Fr4-18I Blade Exceptions; Fc4-48 And Fc8-48 Blade Exceptions; Conserving Power - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

To enable a port blade:
Connect to the switch and log in as admin.
1.
2. Issue the bladeEnable command with the slot number of the port blade you want to enable:
switch:admin> bladeenable 3
Slot 3 is being enabled
FR4- 1 8i blade exceptions
Note the following port blade exceptions:
• You have inserted the FR4- 1 8i blade into a slot that was previously empty or contained an FC4-48,
FC4-32, FC8-48, FC8-32, FC4- 1 6, FC10-6, or FC4- 1 6IP.
• You have turned on the power of the chassis and the FR4- 1 8i blade in that slot was not active prior to
the power-on.
If the FR4- 1 8i blade is operational and the Director is rebooted, after the successful bootup of the system
the blade continues operations using the previous configurations.
If a previously configured FR4- 1 8i blade is removed and another or the same FR4- 1 8i blade is inserted into
the same slot, the ports use the previous configuration and come up enabled.
If a previously-configured FR4- 1 8i blade is removed and an FC4-48, FC4-32, FC4- 1 6, FC8-48, FC8-32,
FC8- 1 6, or FC10-6 blade is plugged in,—other than the port's EX_Port configuration—all the remaining
port configurations previously applied to the FR4- 1 8i 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, any requested port configuration is validated against the blade's capabilities before accepting
the request.
To summarize:
• When an FC4- 1 6, FC4-32, FC8- 1 6, FC8-32, FC10-6, or FC4- 1 6IP blade is replaced by an FR4- 1 8i
blade, the FC configuration of the previously configured FC_Ports continues to be used, and all
FC_Ports on the FR4- 1 8i blade are persistently disabled.
• When an FR4- 1 8i blade is replaced by an FC4- 1 6, FC4-32, FC8- 1 6, FC8-32, or FC10-6 blade, the
EX_Port configuration is removed from any ports that were configured as EX_Ports (equivalent to
disabling the EX_Port configuration by issuing 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- 1 6/32 port blade,
FR4- 1 8i, and FC4- 1 6IP 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 the portSwap command 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.
