Catalyst 2960-X | not booting | Showing " brom> " prompt

Hi,

 

I have a 2960-X switch which was in stack configuration. Users complained about network connectivity and while checking the stack i got below error.

 

Switch1#sh switch 
Switch/Stack Mac Address : 1c1d.8605.1d00
                                           H/W   Current
Switch#  Role   Mac Address     Priority Version  State 
----------------------------------------------------------
 1       Member 1c1d.864a.4180     1      4       Ready               
*2       Master 1c1d.8605.1d00     1      4       Ready               
 3       Member 1c1d.864a.4880     1      4       Ready               
 4       Member 1c1d.8674.7a00     1      4       Ready               
 5       Member 0000.0000.0000     0      0       Removed 

 

So i consoled to the 5th Switch, however it didn't respond to any inputs.

All the switchport LED's connected to user machines were showing Solid GREEN Light. Now i removed it from stack and Power-Cycled the switch and got below error.

Executed reset command, which didn't help in resolving the issueGoogling for Cisco documentation didn't help much either apart from finding a thread ( http://goo.gl/BHDXOg )which suggested that switch has gone bad and has to replaced.

 

Any pointers / suggestions  / explanations would be of great help.

 

Thanks,

Hi Madhu,

Thanks for the input. What i observed is that there no Cisco documentation on this issue apart from few discussions in support forum.
