Chapter 3 Power Supply Installation
Installing a DC Power Supply
Installing the DC Power Supply in the Switch
Before installing the power supply, see the
Installation Guidelines, page 3-7
.
Step 1
Turn off DC power. To ensure that power is off, change the circuit breakers to the OFF position, and tape
the circuit-breaker switches in the OFF position.
Step 2
Remove the plastic safety cover from the power supply terminal blocks (
Figure 3-7
).
If you are not replacing a DC power supply, go to
Step 5
.
Step 3
Use a number-2 Phillips screwdriver to remove the DC-input power wires from the power terminals.
Step 4
Press the release latch at the right side of the power supply module inward, and pull the power supply out.
Step 5
Insert the power supply in the power supply slot, and gently push it into the slot (
Figure 3-14
). When
correctly installed, the DC power supply (excluding the extraction handle) is flush with the switch rear
panel.

Step 6
Connect the input power as described in the
“Wiring the DC Input Power Source”
section.
Wiring the DC Input Power Source
Step 1
Using a wire-stripping tool, strip each of the four wires from the DC-input power source to the
appropriate length for the terminals.
Warning
Use copper conductors only.
Statement 1025
Step 2
Using a Panduit crimping tool, crimp the fork-type terminals to the copper conductor, 90C, 12-AWG DC
power input wires.
Step 3
Connect the DC-input power terminals to the terminal blocks. See
Figure 3-15
or
Figure 3-16
. Make sure
to match the polarity (negative to negative, positive to positive) when connecting the wires to the
terminal blocks. Connect the ground wire to a grounded metal rack or to earth ground if the switch is not
in a grounded rack.
