Chapter 4 Installation and Maintenance

Power Supply Overview

The dual power supply units supply hot-swappable, redundant power. Redundant power is useful as a failover; if a situation occurs where one power supply is down (for instance, a power supply fails or a new power supply needs to be installed), the SCE 1000 can continue to run properly using the other power supply.

Each power supply has fans that cool the power supply unit. These fans also help to cool the internal components of the SCE 1000, as they direct the air flow to the outside through vents in the rear of the power supply unit.

The faceplates of both power supplies have a handle, an on/off switch, and one captive installation screw. An AC-input power receptacle is available on the AC-input power supply and a DC-input terminal block is available on the DC-input power supply.

Note that the power supply units are asymmetrical, with a screw in only one corner of the unit. Therefore, both power supply units can be fastened only if both units are inserted in the proper orientation. This also prevents the accidental installation of one DC unit and one AC unit. (Refer to the following figures).

The handle of the AC unit is at the bottom of the unit.

The handle of the DC unit is at the top of the unit.
