User receives the "Pinnacle Synch Failed" error message at bootup due to either a mis-seated module or a hardware issue

[TCC_2]

Resolution

At bootup, an output similar to this is seen:

In Local Test Mode, Synch Failed. Retries: 4
Local Test Mode encounters Minor hardware problem in Module # 1
Running System Diagnostics from this Supervisor (Module 1)
This may take up to 2 minutes....please wait
Pinnacle Synch Failed. Retries: 4
Minor hardware problem in Module # 1
Use 'show test 1' to see results of tests.

To resolve this issue, perform these steps:

1. Power off the switch.  

2. Check the supervisor engines and all the switching modules to ensure they are firmly seated in the chassis backplane.  

3. Check the ejector levers on the left and right sides of the modules to ensure they are fully engaged (pressed completely against the front panel of the module).  

4. Check the thumb screws on the left and right sides of the modules to ensure they are screwed into the card cage and are tightened hand tight.  

5. Power the chassis back on.  

6. If the Pinnacle Synch Failed message still appears, perform these steps:  

   1. Power off the switch and remove all switching modules and the supervisor engine.      

   2. Re-insert the supervisor engine into the chassis and power on the switch.      

   3. If the Pinnacle Synch Failure message does not occur again, power off the switch, insert one module at a time and power the switch on.      

   4. Repeat this process by adding one module at a time until the problem module is found.
