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 3-5.

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 3-4).

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 3-11). 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 3-12or Figure 3-13. 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.
