Table 6-2 Troubleshooting Miscellaneous Line Card Issues
Problem Solution
Insufficient power
• When multiple line cards are inserted in the
7600 chassis, some cards may not be able to
power up due to insufficient power. If the
power required by the line card exceeds the
power available in the system, the line card is
denied power and is shut down. In such a
case, use the show power command to verify
how much power is used and available.
• Execute the command in the configuration
mode to deny power to a line card.
Router# configure terminal
Router(config)# no power enable module
<slot_number>
On doing this, the power consumed by the line
card before turning it OFF, is returned to the total
power available in the system. This is handy in
bringing up another line card. If you have
manually disabled power to a line card, you can
enable it with the following config mode
command:
Router(config)# power enable module
<slot_number>
Line card image not bundled in the IOS image • For a line card to bootup, the line card image
has to be bundled in the IOS image. Not all
line cards are supported with every image. A
line card does not bootup if its image is not
bundled with the system image. Execute the
show power and dir sup-microcode
commands to determine if the line card image
is bundled with the IOS image.
Find Master Timer expiry
• This problem occurs when the RP does not
process the Find Master Messages in time, or
line card crashes or is unable to download the
image from the supervisor.
• If one of the CPUs is not able to load the
image from the SP, try with a different image
and if the issue persists, replace the flexwan.
If any of the CPUs has crashed, collect the
crash information data to analyze further.
Faulty hardware
Note Bad hardware can also be a reason for the
line card not booting up. There are no
specific pointers which indicate that the
line card hardware is bad. But if none of
the above reasons match the failure of the
line card, it could a bad hardware issue.
• This following message indicates that the
module software cannot read the module
hardware version. This condition indicates a
hardware error.
