Power Supply Module Installation
Step 4
Use a Phillips screwdriver to loosen the two captive screws at the lower edge that secure the power
supply module to the switch chassis (
Figure 11
).
Step 5
Remove the power supply module from the power slot by pulling on the extraction handle.
Step 6
Insert the new power supply into the power supply slot, and gently apply pressure while pushing the
module into the slot (
Figure 11
). When correctly inserted, the power supply is flush with the switch rear
panel.

Step 7
Align the two captive screws with the screw holes in the switch rear panel. Using a ratcheting torque
screwdriver, torque each screw to 10 lbf-in. (160 ozf-in.).
Step 8
Connect the input power as described in the
“Wiring the DC-Input Power Source”
.
Wiring the DC-Input Power Source
To wire the DC-power supply module to a DC-input power source, follow these steps.
Step 1
Using a wire-stripping tool, strip each of the four wires coming from the DC-input power source to the
appropriate length for either the round eyelet or the fork-type terminals.
Step 2
Using a Panduit crimping tool, crimp the terminals to the 16-gauge DC-power input wires.
Step 3
Connect the DC-input power terminals to the terminal blocks as shown in
Figure 12
. Make sure to match
the polarity (negative to negative, positive to positive) when connecting the wires to the terminal blocks.
