Using AC Power with DC Power Backup
Procedure
✔
Make sure that the DC power source wires are not powered (i.e., the circuit
breakers are open).
✔
The ends of the DC power source wires (14–18 AWG solid or stranded wire)
must be stripped of insulation. If they are not stripped of insulation, strip the tip
of each wire (about 1/2-inch in length) before plugging the wire into the
appropriate connector on the – 48V input terminal block. Ensure that each wire
is fully inserted into the terminal (until it can go no further).
To supply both AC and DC power to the Hotwire 8610 DSLAM chassis for power
redundancy:
1. Plug the AC power cord into the IEC 320 receptacle labeled AC INPUT.
2. Insert the wires for the DC power source into 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.
3. Dress the wires under the 8610 chassis to the left and behind the front left
support foot.
4. Plug the other end of the AC power cord into the AC outlet.
5. Power the Hotwire 8610 DSLAM chassis.
6. Make sure the PWR A and PWR B LEDs on the front panel are both ON
(green).
Insert Power Source B’s . . . Into the . . .
Negative side –48V B input terminal.
Positive side RTN B (return) terminal.
