Title: Another odd outage
Post by newnham on Mar 15th, 2008 at 5:36pm
Hey guys. Again I come to you with another wird outage problem. The last time a replacement of the modem was needed, wich BW sent very quickly (THANKS).
Now I am suspecting a BUC or LNB problem, and wouldn't be surprised at all if one of these caused the original failure.

For about 3 weeks now my systems has been going from 96 QRF to 1-15 QRF. When this happens, if I swap my TX and RX cables, the modem completley goes black when I plug the RX into the TX. I did this with the power off, when I didn't get any power i quickly unscrewed both cables and when I unscrewed the bottom cable it came back on. I did this several times and it would go off and on (powering down each time). I have no idea qwhats going on. When the cables are switched, and the light comes back on, I will switch them back and it will work. I got tired of doing that and now it loses all signal, will stay down for hours, and miraculously will come back again. Normally I would think something is blocking the signal, bad weather, or something moved my dish. But this power thing has me believing something else is going on. Does anyonehave any Ideas???

I can't quite follow all your cable swapping - which is a bad idea to begin with. What I can say though, is that these modems have cable-fault protection. Anytime there's a short on either cable, the modem shuts itself down (goes black) as a self-protection measure.

Hi will
U have a ticket open @ our end with no updates
Pls note the BUC is not an issue and infact pls do NOT swap cables as you're detoriating te co-ax edges of the BUC and/or LNB. Kindly liaise with us on the help desk
regards
