Removing and Replacing a Power Supply Unit

Reconnecting AC-Input Power Supply Unit

The following procedures explain how to reconnect an AC-input power to the SCE 2000 platform.

If you are reconnecting DC-input power, proceed to Reconnecting DC-Input Power Supply Unit (on page 4-18).

To reconnect the AC-input power to the SCE 2000 platform, complete the following steps:

Step 1 Plug the AC-input power cable into the AC-input power receptacle on the AC-input power supply

Figure 4-14: Connecting the AC Power

Note For AC-input power, we recommend powering the SCE 2000 platform from a 120 VAC, 15A receptacle U.S. (240 VAC, 10A international) at the power source.

15 A branch circuit protection is recommended.

Step 2 Plug the AC power supply cable into the AC power source. Step 3 Turn the on/off switch to the on (⏐) position.

Step 4 Look at the IN and OK LEDs on the power supply unit and the corresponding Power LED on the front panel. If the new AC-input power supply unit is operating properly, these LEDs will be glowing green.

Step 5 Ensure that the power supply is properly aligned and the installation screw is tightened.

This completes the steps for reconnecting the AC-input power supply to the SCE 2000 platform.

Reconnecting DC-Input Power Supply Unit

The following procedures explain how to reconnect a DC-input power to the SCE 2000 platform.

Warning Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that power is removed from the DC circuit. To ensure that all power to the power supply unit is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Note that the power to the relevant power supply unit should be off, not necessarily all power to the SCE 2000 platform. One DC-input power supply can be running when the other power supply is being removed or replaced.
