[Oliver.Gao36]

Hi all,
I was facing an issue after 2960X switch upgrading IOS to a higher version, after rebooting.
my switch always hangs at

CPU rev: B
Image passed digital signature verification
Board rev: 5
Testing DataBus...
Testing AddressBus...
Testing Memory from 0x00000000 to 0x1fffffff...| S

can someone help to give me solution?

Try performing a hard reboot (pull the power cable).
If things don't improve, contact TAC and organize for an RMA.

i tried. but looks that this cannot solve the issue. seems i will have to open a TAC support.

what was the version it was running before..looks like you hitting with Memory Bug, time for RMA.

[Oliver.Gao36]

previous running IOS version was 15.2.5E, running under bundled mode.

i just downloaded 15.2.7 via TFTP, and set boot system with this version, then performed reloading.

after that, the switch always hangs at testing memory, so unlucky....

Another bad day..time for RMA if you have contract.
