Symptom Recommended Action
At boot up, the following 
message appears:
CHMGR: Slot slot/subslot 
had diagnostic failures - 
NOT STARTING UP
When there is a failure on a CSS 11501 
component, the CSS 11501 attempts the boot 
process three times. If the boot is unsuccessful, 
the CSS generates a log message and saves it in 
the boot.log file. Obtain technical assistance. 
Refer to “Preface”. For information on log 
files, refer to the Cisco Content Services Switch 
Administration Guide.
