Chapter 2 - Installation Quick Start

Powering Up

Before powering-on the MultiArray verify the following information:

• Verify that both power cords are attached to the unit and to a live AC outlet. Both of the

power cords must be plugged in for the system to operate properly.

• Verify that the slide switch on all four power modules is set for the appropriate AC voltage

(either 115V or 230V).

• Verify that the power switch for each of the four power modules is on before master power

switches are turned on.

To power-on the MultiArray:

• Press the Master Power switches on the front of the chassis to the On Position. Then, ensure

that the populated subsegments are also powered up. See Figure 2-18.

• Once the unit has been powered, refer to the Power-Up Notes that follow prior to loading any

software.

Power-Up Notes

Note 1: For the CD-ROM and Floppy drives to be initialized on each SBC, toggle the BCD

display to match the segment. Power-on that segment. Once it has booted, change the BCD

display to the next segment and power it on. Continue this process until all populated segments

are on.

Note 2: If the disk is changed in the CD-ROM or floppy drive, the only SBC that will recognize it

will be the segment selected on the BCD display. The disk (CD or floppy) must be ejected and

reinserted for each segment in order for that segment to see the new disk.

Troubleshooting Power-Up

This system contains two sets of dual power supplies. The right set powers the first five

segments and the left set powers segments 6-9. If a group of segments does not power up,

check that the power switches for each power system are turned on. All individual power supply

module switches should be left on and the master power switches used to turn power to the

segments on and off.
