Managing the interface modules

After you enter this command, the system enters the interface module’s monitor mode. For
example, to boot from the primary IronWare image in the interface module’s flash memory, enter
the following command at the monitor prompt:
LP MONITOR> boot system flash primary
Changing priority of chassis slots for interface modules
You can prioritize the BigIron RX Series chassis slots in which the interface modules are installed.
The priority range is 1 – 8, where 1 is the lowest priority and 8 is the highest priority. You can set
one, some, or all chassis slots to the same priority or each chassis 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 chassis slots is 1, which is the lowest priority. If the supply of power to
the chassis falls below a minimum threshold, the chassis slots will likely lose power because of
their low priority. In this scenario for an BigIron RX-8 chassis, slot 8 will lose power first, then slot 7,
slot 6, and so on until slot 1 loses power.
For example, to set the priority of chassis slot 1 to the highest priority (8), enter the following
command:
BigIron RX(config)# lp-slot-priority 1 8
Syntax: lp-slot-priority <slot-number> <priority>
The <slot-number> parameter indicates that the chassis slot number for which you are changing
the priority. You can specify slots 1 – 4 for BigIron RX-4, 1 – 8 for BigIron RX-8 or 1 – 16 for BigIron
RX-16.
The <priority> parameter indicates that the priority of the chassis slot if the chassis 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 chassis slots to the same priority or each chassis slot to a different priority.
Disabling and reenabling power to the interface modules
If needed, you can disable power to a specified interface module and then reenable it. For example,
to disable power to the interface module in chassis slot 1, enter the following command at the
Privileged EXEC level of the CLI:
BigIron RX# power-off lp 1
Syntax: power-off lp <slot-number>
The <slot-number> parameter indicates the chassis slot number for which you are disabling the
power. You can specify slots 1 – 4 for BigIron RX-4, 1 – 8 for BigIron RX-8 or 1 – 16 for BigIron
RX-16.
For example, to reenable power to the interface module in chassis slot 1, enter the following
command at the Privileged EXEC level of the CLI:
BigIron RX# power-on lp 1
Syntax: power-on lp <slot-number>
The <slot-number> parameter indicates the chassis slot number for which you are re-enabling the
power. You can specify slots 1 – 4 for BigIron RX-4, 1 – 8 for BigIron RX-8 or 1 – 16 for BigIron
RX-16.
