Server signal fail SSF

[Parry]

Hello Guys

I am a Hardware telcoms engineer. My job is to repair SDH nokia
synfonet cards.
At the moment, i am trying to repair a STM-16 WDM optical interface
card.
The NMS is showing an Alarm called SSF in my test bed.
can anyone tell me why am i getting this alarm. This card is only
powered up in the chasis. It is not connected in a network. Im testing
it standalone.

Plz respond.

Without any documentation?

If you are testing it standalone I assume you have no fiber
connected to it. This means the NMS will see Loss of Signal
(LOS). The VC-4 in the STM-16 will report SSF (server signal
fail) as a consequence of the LOS of the optical signal, i.e.
the server signal.

Cheers, Huub.

SSF means Server Signal Fail.

To clear the alarm you have to repair the server signal.

It is as easy/simple as that.
