CBS 3120X-S switch stack member down

I have a 3 member CBS3120X-S stack in a HP C7000 enclosure (switches 1, 3, and 5). Switch 1, (the previous stack master) is not showing up in the stack and all the ports are down. Switch 3 has taken over as master, but I don't know what happened to switch 1.  The system and stack lights are green and I am not seeing any messages in the log. I reset switch 1 and that did not resove the issue. I disconnected the stack cable and reset the switch again (pulled it out and pushed it back in) and connected to it with a console cable. I get nothing on the console, not even rommon mode. I was connected at the default baud rate that worked when I connected the conole of the other switches in the stack, so I don't think is a serial configuration issue. If this is CBS hardware problem, I don't understand why the system light is green.

The only thing that has happened recently is power was shut down and then later restored to this enclosure. I would appreciate any ideas in resolving this. Thanks!

CBS 3120X-S switch stack member down

It appear the switch is bad. I inserted it in another chassis and go the same, nothing on the console, and the system and stack lights green. I don't know what is wrong with it.The only thing I didn't try was different baud rates. We leave everything at the default 9600 so I don't think that is the prolblem. I replaced the bad switch, but is there anything else i can try b
