Problem Description:2009-12-02 03:13
The 10 G link CE3 - ZH2 is down.
Input power level of optical Amplifier mCE22-A7 is 0.
One of the two power feeds for the 2 Sorrento racks failed at 01:40
At 03:13 the optical Amplifier mCE22-A7 crashed.
Deltanet replaced the optical amplifier.
Everything is back to normal.
Deltanet will go to Cern and replace the optical amplifier.
We asked Cern to check the power supply of our Sorrento racks.
There was a power problem at Cern - which is fixed now.
But the optical amplifier in one rack didn't recover.
