In this output example, there is one interface module in slot 2, which is powered off.
device# 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.
device# power-on lp 1
To re-enable power on all interface modules, enter the following command.
device# power-on lp all
In this output example, there is one interface module in slot 3 and slot 3 is powered on.
device# power-on lp all
Slot 3 is powering on.
rw_power_on_lp: write 00070004 to RW_MBRIDGE_CARD_POWER_OFF_REG
Syntax: power-on lp [ slot-number | all ]
• The slot-number parameter indicates the slot number for which you are re-enabling 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 on all interface modules.
Monitoring Link Status
Software and hardware error conditions can bring down fabric links. When all links connecting a traffic manager to a backplane are down,
the traffic manager will drop incoming traffic. If the port is still up, the traffic manager will continue to drop data. NetIron R05.3.00 and
later solve this problem continuously running a software task on the LP that monitors link status. If it detects that if the fabric links
between the traffic manager and the backplane are down, the software shuts down the ports connected to that traffic manager, resulting
in no continuous traffic drop. If all of the following criteria are met, the software brings the ports back up:
• all the links come back up
• at least 30 percent of the total links are in the "up" state
• the port is enabled and there are no additional blocking conditions
Enabling monitoring link status
This feature is included by default in NetIron R05.3.00 and later; no configuration is required to enable it.
Disabling monitoring link status
To disable the link status monitoring feature, enter the following command:
no system-monitoring tm port-control
