Installing and Connecting the Hardware
Supplying Power
The HotWire 8600 DSLAM chassis is available in two versions:
dc power (±40.0 to ±60.0 Vdc; maximum current draw is 2 amps)
ÐThe dc version has two separate dc inputs, A and B, to provide power redundancy.
ac power (100 ± 250V; 50 ± 60 Hz; maximum current draw is 3 amps @ 110 Vac)
ÐThe ac version can provide power redundancy if a separate ± 48 Vdc source is connected to the B input terminal.
Using a Single DC Power Source
"Procedure
To supply ±48 Vdc power to the 8600 chassis from a single ±48 Vdc power source:
Make sure that the dc power source wires are not powered (i.e., the circuit breakers are open).
The ends of the power source wires (14 AWG ± 18 AWG solid or stranded wire) must be stripped of insulation. If the wires are not stripped, strip the tip of each wire (about
1.Insert the following wires in the appropriate terminal and securely fasten each wire by tightening the screw above it. The insulation should be fully within the terminal block and no bare wire should be exposed outside of the block.
NOTE:
You should clearly label these power source wires as ±48V and RTN respectively.
