Chapter 12: Troubleshooting
Ethernet Line Cards
232
A quick and easy way to check the overall heath of the Ethernet line cards
in the chassis is by examining the SBx STATUS LEDs on the controller
card. (If the chassis has two controller cards, you may use the LEDs on
either card.) There are twelve LEDs, numbered 0 to 11, but the AT-
SBx3106 Chassis uses only LEDs 0 to 5, (LEDs 6 to 11 are always off.) A
solid green LED indicates that the card in the corresponding slot is
operating normally. The Ethernet line card in slot 2 of the chassis, for
example, is operating properly when the SBx STATUS LED 2 on the
controller card is solid green.
If you suspect a problem with an Ethernet line card or controller card, try
the following:
If all the L/A LEDs on the card are off, try pressing the eco-friendly
button on the active master controller card to verify that the LEDs
on the line cards are on.
Check the card's status LED in the SBx STATUS LEDs on the
controller card. If the LED is flashing amber, the card is initializing
its management software. Wait one to two minutes for the card to
complete the process. If the LED does not change to green, try
installing the line card in a different slot. If the problem remains, the
card cannot complete the initialization process. Try installing the
card in another chassis with a different controller card.
If the card's status LED in the SBx STATUS LEDs on the controller
card is solid amber, the card might not be able to boot up because
the controller card does not have its load file. This can happen if a
line card requires a newer version of the management software
than what is currently on the controller card. To correct the
problem, update the management software on the controller card
to the latest release.
A line card may not boot properly if the load file has not be set
correctly with the SET CARD PREFLOAD command on the active
master controller card.
Here are some other steps to try:
Check that the card is completely installed in the slot and that the
front plate is flush with the front of the chassis.
Try resetting the card with the RESTART CARD command. The
example of the command restarts the card in slot 2:
officer SEC>> restart card 2
You will be prompted as follows - enter y for YES:
Do you really want to restart card 2 (Y/N)? y
