Troubleshooting Chapter 7 Troubleshooting the Installation Table 7-2 Troubleshooting Miscellaneous Line Card Issues Problem Insufficient power Solution • 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 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: Line card image not bundled in the IOS image Find Master Timer expiry 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. Router(config)# power enable module • 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. • 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. • This following message indicates that the module software cannot read the module hardware version. This condition indicates a hardware error. 00:02:51: %CWPA-2-BAD_HWVERS: Unable to determine board hardware version Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide 7-4 OL-5052-14
