Paradyne Hotwire 8620 GranDSLAM Installation Guide manual 2-11, Procedure

2. Installation

Using Two DC Power Sources for Power Redundancy

Procedure

✔Make sure that the DC power source wires are not powered (that is, the circuit breakers are open).

✔The ends of the power source wires (14–18 AWG or 2.5 mm2 solid or stranded wire) must be stripped of insulation to about 1/2 inch (12.7 mm) in length before inserting the wires into the appropriate terminal on the –48V input terminal block.

To supply two DC power sources to the 8620 chassis for power redundancy:

1.Insert the following wires in the appropriate terminal and securely fasten each wire by tightening the screw directly above it. The insulation should be fully within the terminal block and no bare wire should be exposed outside of the block.

2.Clearly label these four power source wires as –48V A, RTN A, –48V B, and RTN B respectively.

Insert Power Source . . .	Into the . . .
