7Managing interface modulesAfter you enter this command, the system enters monitor mode on the interface module. To bootfrom the primary image in flash memory on the interface module, enter the following command atthe monitor prompt.LP MONITOR> boot system flash primarySyntax: boot system flash primaryChanging priority of slots for interface modulesYou can prioritize the slots in which the interface modules are installed. The priority range is 1 (low)– 8 (high). You can set one, some, or all slots to the same priority or each slot to a different priority.If you assign the same priority to all slots, the lowest-number slot has the highest priority, while thehighest-numbered slot has the lowest priority.By default, the priority of all slots is 1, which is the lowest priority. If the supply of power to therouter falls below a minimum threshold, the slots will likely lose power because of their low priority.In this scenario for an 8-slot router, slot 8 will lose power first, then slot 7, slot 6, and so on until slot1 loses power.To set the priority of slot 1 to the highest priority (8), enter the following command.Brocade(config)# lp-slot-priority 1 8Syntax: lp-slot-priority • The parameter indicates that the slot number for which you are changing thepriority. You can specify 1 – 4 for 4-slot routers, 1 – 8 for 8-slot routers, 1 – 16 for 16-slotrouters, or 1 – 32 for 32-slot routers.• The parameter indicates the priority of the slot if the router loses power. You canspecify a value of 1 – 8, where 1 is the lowest priority and 8 is the highest priority. You can setone, some, or all slots to the same priority or each slot to a different priority.Disabling and re-enabling power to interface modulesYou can disable and re-enable power to a specified interface module, or to all interface modules.For example. to disable power to the interface module in slot 1, enter the following command at thePrivileged EXEC level of the CLI.Brocade# power-off lp 1To disable power on all interface modules, enter the following command:Brocade# power-off lp allIn this output example, there is one interface module in slot 2, which is powered off.Brocade# power-off lp allSlot 2 is powered off.rw_power_off_lp: write 00030000 to RW_MBRIDGE_CARD_POWER_OFF_REGSyntax: power-off lp all• The parameter indicates the slot number for which you are disabling the power.You can specify 1 – 4 for 4-slot routers, 1 – 8 for 8-slot routers, 1 – 16 for 16-slot routers, or 1– 32 for 32-slot routers.• The all parameter allows you to power off all interface modules.To re-enable power to the interface module in slot 1, enter the following command at the PrivilegedEXEC level of the CLI.344 Brocade MLX Series and Brocade NetIron XMR Hardware Installation Guide53-1002373-02
