4500 switch dead ports / no Poe

[jonathang]

Hi

I have a Cisco 4500. Recently some of the ports seem to have "died"/ will not supply Poe to phones. Some work for data only. Other do not work at all.

The switch has been restarted, this made no difference.

Anyone any ideas before I get a new blade?

2.  Wait for 61 seconds;

3.  Command:  sh cable tdr interface ; and

4.  Post the output

Hi thanks.

Turned out tone a card fault. Poe was continually restarting. New card on way from Cisco.
