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.
