[solved] ProCurve E2920 48PoE random network ports not working

[MikeKesler]

We are using four ProCurve E2920 48 Port PoE Switches, Version WB.15.11.0003, ROM WB.15.04, with J9731A Extension Modules and J9150A Gbic Modules.

One of the switches lost connectivity on Ports 46 and 48 - both ports show up as:

Port Table:
Port Status: Down

Tx Errors: 0

Tx Util%: 0

Rx Util%: 0

Type 100/1000T

Current Mode: 1000FDx

Config Mode: Auto

Port Properties:

Port: 48

Enabled: Yes

Mode: Auto

Flow Control: Disabled

Broadcast Limit: 0

LACP Status: Disabled

If we plug in a network cable into either one of these ports, nothing happens - Link does not come up, it doesn't even detect a connected cable.

After resetting the router several times, Port 46 came back to life, but Port 48 still fails. However, since a couple of days, we are also having the same problem on another E2920 48 Port PoE Switch with the same setup - This time, Port 2 died and hasn't come back yet.

Any ideas of what could be wrong and what we could try to resolve this issue?

Regards, Mike

[Edit: Turns out the switches are defective and are to be replaced]

Do a 

"show interface brief".

And a

"show interfaces transceivers"

And post the results here.

From Switch 1 (with Port 46 (sometimes) and 48 not working):

What if you manually set the misbehaving ports to 100Mb Full. 

What happens?

(On both sides of each link, of course).

[MikeKesler]

We tried that, unfortunately it didn't change anything at all.

I also opened a support case with hp and send them the "show tech all" output. They now determined the switches to be defective and are going to replace them. So the case is pretty much closed as of today. :)
