Ticket Description: Hardware failure at DWDM node Zurich-Irchel

Problem Description:

A failure occured on the Sorrento DWDM amplifier node (mZH13) at the SWITCH PoP Uni Zurich Irchel. The system reports: mZH12 rack2, power2 alarm.

The link "Lambda-10GE CH17 to swiCE3" was therefore down.

After the replacement of the power supplies, some reconfiguration of the modules was needed to bring the links up again.
