This message typically means a hardware failure.

If you plug a console into the switch and watch it boot, you should see a particular message indicating POST failure on a specific line, something like this:

POST: PortASIC CAM Subsystem Tests : Begin

TCAM (asic:5) walking-one test failed

Write: 80_00000000_00000000-00_00010000_00000000

Read: 80_00000000_00000000-00_04000000_00000000


POST: PortASIC CAM Subsystem Tests : End, Status Failed

POST: CAM test failed

If this switch is under contract, it should be RMA'd

Call cisco the 2960 has a limited lifetime warranty. If you don't have a contract I think replacement time is like 10 days.
