Disabling and enabling port blades Port blades are enabled by default. In some cases, you will need to disable a port blade to perform diagnostics. When diagnostics are executed manually (from the Fabric OS command line), many commands require the port blade to be disabled. This ensures that diagnostic activity does not interfere with normal fabric traffic. To disable a port blade: 1. Connect to the switch and log in as admin. 2. Enter the bladeDisable command with the slot number of the port blade you want to disable: switch:admin> bladedisable 3 Slot 3 is being disabled To enable a port blade: 1. Connect to the switch and log in as admin. 2. Enter the bladeEnable command with the slot number of the port blade you want to enable: switch:admin> bladeenable 3 Slot 3 is being enabled B-Series MP Router blade (FR4-18i) exceptions You may wish to persistently disable B-Series MP Router blade ports that are not configured so they cannot join the fabric when the following scenarios apply: • You have inserted the blade into a slot that was previously empty or contained an FC4-48, FC4-32, FC4-16, or FC4-16IP. • You have turned on the power of the chassis and the B-Series MP Router blade in that slot was not active prior to the power-on. If the B-Series MP Router blade is operational and the switch is rebooted, then after the successful boot up of the system the blade will continue operations using the previous configurations. If a previously configured B-Series MP Router blade is removed and another or the same B-Series MP Router blade is inserted into the same slot, then the ports will use the previous configuration and come up enabled. If a previously-configured B-Series MP Router blade is removed and an FC4-48, FC4-32, or FC4-16 blade is plugged in, then-other than the port's EX_Port configuration-all the remaining port configurations previously applied to the B-Series MP Router FC_Ports can be used. So the EX_Port configuration on those ports will be disabled before the FC4-48, FC4-32, or FC4-16 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 or FC4-32 blade is replaced by an B-Series MP Router blade, the FC configuration of the previously configured FC_Ports will continue to be used, and all FC_Ports on the B-Series MP Router blade will be persistently disabled. • When an B-Series MP Router blade is replaced by an FC4-16 or FC4-32 blade, then the EX_Port configuration will be 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 will be retained. FC4-48 blade exceptions The FC4-48 blade is compatible only with the FC4 control processor blade, FC4-16/32 port blade, B-Series MP Router, and FC4-16IP iSCSI blade. Because the area IDs are shared with different port IDs, the FC4-48 blade only supports F, G and E_Ports. Port swapping on an FC4-48 is supported only on ports 0-15. For the FC4-32 blade port swapping is supported on all 32 ports. This means that if you replace an FC4-32 where a port has been swapped on Fabric OS 5.3.0 administrator guide 209
