Power Supply - DEC AlphaServer 1000A Owner's Manual

Power Supply

The following procedures describe how to install and remove the primary and
optional power supplies. The primary power supply resides in the bottom position,
the secondary power supply in the top position. The procedures for installing and
removing both power supplies are similar, unless otherwise noted.
Installing the Power Supply
To install a power supply, refer to Figure 5-15, and follow these steps:
1. If you are installing a second power supply, remove the four screws that secure
the protective shield at the back of the system unit. Remove the shield and store
it with the screws for future use.
2. Slide the power supply over its tabs and toward the back panel so that it aligns
with the screw holes in the system unit frame. The primary power supply slides
directly into the lower position from the side of the system unit. The secondary
power supply slides down from above the system unit and rests upon a ledge.
3. Tighten the two screws that secure the internal end of the power supply.
4. Tighten the four screws that secure the power supply to the outside of the unit.
Do not use the screws that secured the protective shield.
5. Connect all internal and external cables to the power supply. If you are
installing a second power supply, an additional internal cable is required for
connecting the two supplies. Each power supply connects directly to an AC
outlet.
