Chapter 3 Power Supply Installation

Power Supply Module Installation

Step 5 Use a ratcheting torque screwdriver to tighten the ground screws to 30 in-lb (± 2 in-lb).

Step 6 Attach the other end of the ground wire to a grounded bare metal surface, such as a ground bus or a grounded bare rack.

Installing the Power Supply Module in the Switch

Step 1 We recommend that power be off at the AC or DC circuits. Locate the circuit breakers, turn them OFF, and tape them in the OFF position.

Note If the power is not off at the AC or DC circuit breaker, do not touch the power-input terminal.

Step 2 Use a Phillips screwdriver to loosen the two captive screws of the blank power supply module and gently pull it out. See Figure 3-6and Figure 3-7.
