Chapter 3 Power Supply and Fan Module Installation

Installing a DC Power Supply

Step 5 Use the ground screw to attach the single-ground lug to the switch rear panel. Use two ground screws to attach the dual-hole lug to the switch rear panel (Figure 3-10).

Step 6 Using a ratcheting torque screwdriver, torque the ground-lug screws to 60 lbf-in. (960 ozf-in.).

Step 7 Connect the other end of the grounding wire to an appropriate grounding point at your site or to the rack.

Installing the DC Power Supply in the Switch

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.
