Appendix A Troubleshooting the Boot Process
CSS 11503 and CSS 11506 Boot and Module
Verification
OL-6037-01
If there is a component failure, the CSS 11501 attempts the boot process three
times. If the boot is unsuccessful, the CSS generates the following log message
and saves the message in the boot.log file:
CHMGR: Slot slot/subslot had diagnostic failures - NOT STARTING UP
If this problem occurs for a CSS 11501, contact TAC for technical assistance.
After the CSS 11503 or CSS 11506 completes the Offline DM boot process, the
CSS displays the main banner and starts the Online Diagnostic Monitor (OnDM).
During OnDM, the SCM downloads software to each of the modules and boots
the modules. The SCM verifies that each module is functioning.
If there is a module failure, the SCM attempts to boot the module three times. If
the SCM is unsuccessful, the CSS generates the following log message and saves
the message in the boot.log file:
CHMGR: Slot slot/subslot had diagnostic failures - NOT STARTING UP
The SCM disables the slot and no longer recognizes it. If you use the show chassis
command, the slot does not appear. If a module failure occurs:
1. Power down the CSS.
Reseat the module.
2.
Power on the CSS.
3.
If reseating the module does not correct the failure, replace the module.
For additional information on troubleshooting the modules during normal CSS
operation, see the Cisco 11500 Series Content Services Switch Hardware
Installation Guide.
