Chapter 3 Power Supply and Fan Module Installation Installing a DC Power Supply Installing the DC Power Supply in the Switch See the Installation Guidelines, page 3-5. Step 1 Step 2 Step 3 Step 4 Step 5 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. 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. Use a number-2 Phillips screwdriver to remove the DC-input power wires from the power terminals. Press the release latch at the right side of the power supply module inward, and pull the power supply out. 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.

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 Step 3 Using a Panduit crimping tool, crimp the fork-type terminals to the copper conductor, 90C, 14-AWG DC power input wires. Connect the DC-input power terminals to the terminal blocks. See Figure 3-12 or 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. OL-19593-02 Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 3-11
