Using Two DC Power Sources for Power Redundancy
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 to about 1/2-inch in length before plugging the wires
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 two DC power sources to the Hotwire 8610 DSLAM 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.
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 and PWR B
LEDs on the front panel are both
ON (green).
Insert Power Source . . . Into the . . .
Negative side of the first power source
(Power Source A) –48V A input terminal.
(Optional) Negative side of the second
power source (Power Source B) –48V B input terminal.
Positive side of the first power source
(Power Source A) RTN A (return) terminal.
(Optional) Positive side of the second
power source (Power Source B) RTN B (return) terminal.
