In this output example, there is one interface module in slot 2, which is powered o.
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-o 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 o 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
trac manager to a backplane are down,
the trac manager will drop incoming trac. If the port is still up, the trac 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 trac manager and the backplane are down, the software shuts down the ports connected to that trac manager, resulting
in no continuous trac 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
conguration 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
