Option 2 further provides the ability to be used as a redundant power supply for the radio links. The AirLaser
IP1000plus is first inserted as in the variant 1 in the terminal unit (see above). The backup is connected to
the port TP2 on the AirLaser IP1000plus. The AirLaser IP1000plus thus takes over the power supply to the
backup, and data switching in the event of an interruption of the optical link.
If the AirLaser IP1000plus or the power supply fails through a technical defect, the backup system can be
plugged to the second port of the PoE injector unit. In parallel, the cable must be removed at TP1 and TP2 of
AirLaser IP1000plus and connected by the enclosed coupling.
