Changing Priority Of Slots For Interface Modules; Disabling And Re-Enabling Power To Interface Modules - Brocade Communications Systems MLX Series Installation Manual

Brocade(config)# lp boot system tftp 123.123.123.123 primary all
Syntax: lp boot system tftp <ip-address> <filename> [all | <slot-number>]
•
The ip-address parameter specifies the IP address of the TFTP server from which the interface modules will be booted.
•
The filename parameter specifies the name of the image from which to boot the interface modules.
•
The all | slot-number parameter specifies that the automatic boot applies to all interface modules in the router or to an interface
module in the specified router slot number. 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.
Configuring an automatic interactive boot
To configure an automatic interactive boot for all interface modules, enter the following command at the global CONFIG level of the CLI.
Brocade(config)# lp boot system interactive all
Syntax: lp boot system interactive [all | <slot-number>]
The all | slot-number parameter specifies that the automatic boot applies to all interface modules in the router, or to an interface module in
the specified slot number. 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.
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 (What about the monitor prompt?)
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
