Switch Connection
Caution: The redundant power supply should be
disconnected from its power source before connecting
to the switch. Directly connecting a powered RPS to
the switch may cause damage to the switch's internal
power supply.
Insert one end of the DC power cable into the
receptacle on the switch and the other end into the
redundant power supply.

be damaged if using a 14-pin cable instead of the
correct 22-pin DC power cable.
