Managing interface modules
7
After you enter this command, the system enters monitor mode on the interface module. To boot
from the primary image in flash memory on the interface module, enter the following command at
the monitor prompt.
LP MONITOR> boot system flash primary
Syntax: boot system flash primary
Changing priority of slots for interface modules
You 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 the
highest-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 the
router 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 slot
1 loses power.
To set the priority of slot 1 to the highest priority (8), enter the following command.
Brocade(config)# lp-slot-priority 1 8
Syntax: lp-slot-priority <slot-number> <priority>
• The <slot-number> parameter indicates that the slot number for which you are changing the
priority. 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 <priority> parameter indicates the priority of the slot if the router loses power. You can
specify a value of 1 – 8, where 1 is the lowest priority and 8 is the highest priority. You can set
one, some, or all slots to the same priority or each slot to a different priority.
Disabling and re-enabling power to interface modules
You 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 the
Privileged EXEC level of the CLI.
Brocade# power-off lp 1
To disable power on all interface modules, enter the following command:
Brocade# power-off lp all
In this output example, there is one interface module in slot 2, which is powered off.
Brocade# power-off lp all
Slot 2 is powered off.
rw_power_off_lp: write 00030000 to RW_MBRIDGE_CARD_POWER_OFF_REG
Syntax: power-off lp <slot-number> all
• The <slot-number> 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 Privileged
EXEC level of the CLI.
