Supplying Power
The Hotwire 8610 DSLAM chassis is available in two versions:
H
dc power (– 40.0 to – 60.0 Vdc; maximum current draw is 2 amps)
— The dc version has two separate dc inputs, A and B, to provide power
redundancy.
H
ac power (100–250V; 50–60 Hz; maximum current draw is 3 amps @ 110 Vac)
— The ac version can provide power redundancy if a separate – 48 Vdc source is
connected to the B input terminal.
CAUTION:
It is recommended that the following procedures be performed by a qualified
electrician.
Using a Single DC Power Source
"
Procedure
To supply – 48 Vdc power to the 8610 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 (14–18 AWG solid or stranded wire) must
be stripped of insulation. If the wires are not stripped, strip the tip of each wire
(about 1/2-inch in length) before inserting the wire into the appropriate terminal
on the – 48V input terminal block. Ensure that each wire is fully inserted into
the terminal (until it can go no further).
1. Insert the following wires into Terminal A 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.
