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

 

 

• This following message indicates that the

 

 

 

 

 

 

 

 

 

 

module software cannot read the module

 

 

 

 

 

 

 

 

 

 

hardware version. This condition indicates a

 

 

 

 

Note

Bad hardware can also be a reason for the

 

hardware error.

 

 

 

 

 

 

 

line card not booting up. There are no

 

00:02:51: %CWPA-2-BAD_HWVERS: Unable to

 

 

 

 

 

 

 

specific pointers which indicate that the

 

 

 

 

 

 

 

 

 

determine board hardware version

 

 

 

 

 

 

 

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.
