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. Extreme NetIron software
R05.3.00 and later solved this problem by continuously running a software task on the LP that monitors link status. If it detects that 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 the Extreme NetIron software 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
Displaying fabric link status
To display the fabric link status, enter the following command:
MLX#show sfm-links 1
SFM#/FE# | FE link# | LP#/TM# | TM link# | link state
----------+-----------+---------+-----------+---------
1 / 1 | 13 | 2 / 1 | 13 | UP
1 / 1 | 17 | 2 / 2 | 01 | DOWN
1 / 1 | 14 | 2 / 1 | 01 | UP
Syntax: show sfm-links sfm-number | all [ errors ]
