Question

Cisco Catalyst Switch 3560 is not working - looking for advice

Hi community,

I am using Cisco Catalyst 3560G which was not in use for a while.

When I start the switch, firstly it hangs during boot then I reset it multiple times and then the page (see below) appears on the console but I'm not able to run any command.

Secondly, all ports are not responding: when I check them no ports or led up when I connect it.

What should I do? Does it is related to hardware failure or a firmware issue? Possibly, something else. Please advise!

It appears that you are in RONMON mode for that switch, which limits functionality and features. if powercycling the switch does not boot to the iOS then you will need to reload the iOS version onto the switch.

In order to recover from rommon you will need to re-install an OS on the switch.

This is accomplished via a TFTP download. The commands can be found on the Cisco website. You will need to have a TFTP server running on a PC you connect to the switch. I recommend using Pumpkin from the Klever group.
