connector (rear view).
3 Plug the power cord for PSU2 into the power receptacle on the left
connector (rear view).
4 Plug the other end of each power cord into separate grounded AC
power sources.
Caution
To obtain power supply redundancy, make sure that you connect the
second power supply to a separate AC circuit.
5 Fasten the power cord with the clamp.
