I have a switch 4507 which has default
PoE Enabled.today first time I am testing this feature.But it is not detecting any device as Wireless Access point or IP phone.Any immediate help will be appreciated.
one power supply is off.
What is important is that the linecards look like the wrong type:
WS-X4548-GB-RJ45V this support PoE you have WS-X4548-GB-RJ45 and the missing V is for PoE
you can see in the link of first Massimiliano's post: all linecards supporting PoE have a final V in the part number.
Hope to help
