Chapter 4 Maintenance and Upgrade Procedures for the ASA 5500-X

Removing and Installing the Power Supply

Note If only one power supply is installed, make sure that it is installed in slot 0 (left slot) and that slot 1 (right slot) is covered with a slot cover.

To connect the DC power supply on the appliance, follow these steps:

Step 1 Make sure that the chassis ground is connected on the chassis before you begin installing the DC power supply.

Step 2 Turn off the circuit breaker to the power supply.

Step 3 From the front of the appliance, verify that the power switch is in the Standby position.

Step 4 Move the circuit-breaker switch handle to the Off position, and apply tape to hold it in the Off position.

Step 5 Use a 10 gauge wire-stripping tool to strip each of the three wires coming from the DC input power source. Strip the wires to 0.27 inch (7 mm) + 0.02 inch (0.5 mm). Do not strip more than the recommended length of wire because doing so could leave the wire exposed from the DC power supply connection. (See Figure 4-22.)

We recommend that you strip the wire to 0.27 inch (7 mm).

Warning An exposed wire lead from a DC input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC input power source wire extends from the terminal block plug. Statement 122

Step 6 Identify the positive, negative, and ground feed positions for the DC power supply connection. The recommended wiring sequence is as follows (see Figure 4-23 on page 4-18):

•Ground lead wire (middle)

•Positive (+) lead wire (left)

•Negative (–) lead wire (right)
