Using a Single DC Power Source
Procedure
✔
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).
To supply –48 VDC power to the Hotwire 8610 DSLAM chassis from a single
–48 VDC power source:
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.
2. Dress the wires under the 8610
chassis to the left behind the
support foot.
3. Power the Hotwire 8610 DSLAM
chassis.
4. Make sure the PWR A LED on
the front panel is ON (green).
Insert Power Source A’s . . . Into the . . .
Negative side of the power source –48V A input terminal.
Positive side of the power source RTN A (return) terminal.
