We have two HP Procurves with GBIC connectors on each end. They are plugged in with fiber on each side. The only issue is the link lights on both ends blinks green with no activity. On both sides they turn green for 2 seconds then turn off. Repeating this over and over.

What could be the cause of this?

Do we need to configure anything within the router?

Hi,

Check to make sure that the ports are enabled and configured correctly.  Double check your settings on the switch.

DO you have any problems ? or are you only concerned about the blinking ?

If its just the blinking can you paste the config for the ports the gbics are in at either end ?

Does the fault light blink too?
If it is going on and off ever 1.6 seconds, then it indicated that its a faulty port.

Also, Have you tested the fiber link? / has it worked previously?
It could be an issue of length or possible flaws in the fibre, and the switch is not negotiating it correctly.

The vendor installed cheap GBICs.
