And Yet Another PoE Problem

Ivan Villagomez · ‎09-20-2011

hi Guys

I just received 12 Cisco IP Cameras 2600 i was configuring them on the same port of my switch 3750-X and out of the 12 Cameras, 5 are sending me the next debug:

Ive tried rebooting the switch, upgradin the IOS to latest version, etc.

I know the problem is not the port as i connect another camera and it works.

Do you have any suggestions?

%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/9: Power Controller reports power Tstart error detected

Hmmmm ... I've seen this error message a few days ago.

Can you try something for me?

1. Command: test cable tdr int Gi1/0/9;

2. Wait for about 5 to 7 seconds;

3. Command: sh cable tdr int Gi1/0/9; and

4. Please post the complete output.

Interface Speed Local pair Pair length Remote pair Pair status

--------- ----- ---------- ------------------ ----------- --------------------

Gi1/0/9 auto Pair A N/A N/A Normal

Pair B N/A N/A Normal

Pair C 2 +/- 10 meters N/A Short

Pair D 3 +/- 10 meters N/A Short

This ouput is with the camera connected.

I believe you just solved the issue.

Look at Pair C and Pair D.

Pair C controls PoE and Pair D controls GigabitEthernet. The result is coming up as "Short". Ideal result should be "Normal".

The distance of 2 and 3 metres respectively tells me that the cable directly connected to the switch could be faulty and needs to be replaced.

Can you investigate this?
