Alcatel Unleashed

Hi,
I have receioved the following error on one of my OS9700 switches.

INTERFACE warning SFP/XFP Rx Power=0.000 mW on slot=5 port=2, crossed DDM threshold for low alarm.

This is a link to a remote site (a 10G link) - does this mean the port reset for some reason & what could be the cause ?
Thanks

I'd interpret that as that the RX Level is 0.00mW which means the switch is not receiving any "light" on 5/2.

Do you have link/connection on this port?

If unsure open a SR.
