Just picked up a used Cisco catalyst 2924c-xl switch. Once the switch has posted I have four dead ports (amber) and the system LED is also amber. I've done a 'write erase' and also loaded the latest IOS. Logs show ports 5-8 are dead.."looped-back packet not received". System light was amber as well as ports 5-8 before I did anything and nothing has changed since IOS load or write erase. Cisco troubleshooting doc says Firmware could be corrupt and links to article on how to reload IOS. I don't need all the ports so dead ports are no big deal. I'm just concerned about the amber System LED. Post showed everything else posted successfully. Any ideas or is this switch bad? Thanks in advance!
