Catalyst 2960-X series booting loop

[shsong21]

Cisco 2960-x switch boots repeatedly after a power failure.
The log below is what I find suspicious.
Please help me.

POST: MA BIST : End, Status Failed

POST: BIST failed

I am waiting your good answer.

Thanks so much.

Hi There!

I would recommend for you to install the Cisco Recommended IOS, since yours is quite a bit old.

Install it via xmodem, if you change the baud rate to 115200 it wont take that long.

If the issue persists it could be a possible hardware issue.

Hardware is dead.  Contact Cisco TAC and arrange for an RMA.

Oh, dear.  This does not bode well.
