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!
