Connecting the System to Electrical Power

4-10 Express5800/320Ma: System Installation Guide

Connecting the System to a UPS

1. Locate two black power cords and two labels, A and B.

2. Attach an A label to one power cord. Connect the power cord according to the

system you have:

• Rack-mounted system: Connect one end of the cable to the receptacle on the

top CPU- I ⁄ O enclosure. Connect the other, country-specific, end to the UPS.

• Pedestal system: Connect end of the cable to the receptacle on the right

CPU- I ⁄ O enclosure. Connect the other, country-specific, end to the UPS.

CAUTION

Make sure the power interlock mechanism is unlocked

when you insert the power cord. On rack-mounted

systems, the unlocked position is vertical and on pedestal

systems the unlocked position is horizontal. In Figure 4-1

and in Figure 4-2, the interlock mechanism, located

beneath the power connector, is shown in the unlocked

position. In Figure 4-3 and in Figure 4-4, the interlock

mechanism is shown in the locked position.

3. Attach a B label to the second power cord. Connect the power cord according to

the system you have:

• Rack-mounted system: Connect one end of the cable to the receptacle on the

top CPU- I ⁄ O enclosure. Connect the other end to a second, separate, power

source.

• Pedestal system: Connect end of the cable to the receptacle on the left

CPU- I ⁄ O enclosure. Connect the other end to a second, separate, power

source.

4. From the front of the system, make sure that the CPU- I ⁄ O enclosures are fully

inserted in the shelf unit by tightening, if necessary, the thumbscrews. Then, at the

rear of the system, turn the power interlock mechanisms into the locked position.

To configure the system to communicate with a UPS in the case of a power outage,

see the Express5800/320Ma: Software Installation and Configuration Guide.
