Hej,

I've got a couple of S4128s, and today one was shutdown during a power outage. After the power  came back, the device was not working properly. System led was blinking slowly.  No interfaces came up. 

Attached a serial cable, saw the switch name and login prompt, and drew a sigh of relief. However, as I tried to log in, any valid username I entered never resulted in asking for a password—just something (forgot the exact wording) indicating that the username did not exist. So, I tried the defaults in case something had reset the user/passwords—the same result. 

I then rebooted the device and watched the boot process. It seemed normal. The only item that did pop up was a couple of messages indicating a filesystem or block errors on the storage. 

In the usual case, I'd run fsck.ext(whats used) on the device, however, not sure how I would go about doing that on the switch. Any tips? or do I have to reinstall the OS?
