Cisco Catalyst 3750G - Loops on POST
good day everyone,
i have a 3750 cisco switch that keeps looping on POST for some reason. the following is what i have tried:
ctrl-break to get into ROMMON mode
and that's about all i can do. i cannot get into the IOS or boot in rommon mode to change the config register. any ideas what i can do to start from scratch with this switch? any help is appreciated, thank you all.

So what happens when you press ctrl-break?
ASKER
it continues right through and goes back to uncompressing the flash file.
ASKER
i will give this a try, i will get back to you soon. thank you.
ASKER
that did no work either:
this is what i can capture as the window scrolls up while going through POST:

that's what i thought. so the message:
POST: PortASIC CAM Subsystem Tests : End, Status Failed
which deals with where mac-addresses are kept means the memory could be bad?

Yes, I would call Cisco and try to get it replaced.
Been doing some reading, if you have a smartnet: go to cisco.
If you don't, get one, register it, wait for a day and go to cisco.
You can get a smartnet even if the device is purchased earlier. And it's cheaper than buying a new one.
