2.3 Power Connection
Connect the -48V dc power supply as shown in
shielded. For power supply redundancy, attach each pair of connectors to a separate power
source. If only one power source is available, to create power supply redundancy, join the two
sets of connectors in parallel to each other.
Warning: To fully power down the unit equipped with -48V dc connectors, shut off power at
the connecting power source. Do not disconnect dc connectors at terminal blocks on rear of
chassis while power is being supplied to the unit.
