I have already tried rebooting it and updating to the latest ios (12.2(52)SE - IP-BASE) but I still have access to only the first 8 ports. I have 16 servers connected to these dead ports (all running at 1000 in Auto mode). At least 24 of these dead ports have functioning equipment attached.
Thanks

Hi Eric,
The only thing that I can think of is that the hardware has been damaged in some way. It sounds like some ASICs have become defective, as often 8 ports are controlled by one ASIC.
But I do not have any definitive answer.
Did anything special happen when these ports became unresponsive?

These are my DR servers. The data center did some "testing and splicing unused fibers" and during that timeframe I lost 40 ports, however, the firewall and vpn are still up along with my APC Remote Controlled power outlets so I was able to telnet into the switch and reset power with the APC but to no avail. I have not done a reset to factory defaults yet ...

Usually it will tell you in the log if you have rebooted if there is a hardware error . You can try a "show diag result" and see if the ports show as faulty . If so it's RMA time. What do they look like when you do a show int status " ?

Hi Eric,
When dealing with fibre, I get nervous when someone decides to do some splicing near the live connection. Can you check if the fibres were not terminated incorrectly or left spliced?

All cable work was done outside of our locked rack cabinet. This data center has hundreds of racks. There is only one feed into our cabinet which goes to a switch> firewall> cisco3750. The switch and firewall are both functioning fine. Only the Cisco lost 40 ports.

It is certainly suspect when it does not detect any hardware issue and all the ports look normal just in a notconnect state . Take a live good known device and move it to one of the suspect ports and see if it comes up.
