Hello colleagues, I have installed a redundant Supervisor III in my Cat5509. The problem is that the switch doesn4t see the module, it says that Module 2 is empty. The system status LED on the module is RED, which probably means that one of the self tests has failed. I am not sure how to find out what the problem is. Is there a way to determine why the module isn4t recognized ? Thanks in advance for your help.
