8.Connect the hard disk SCSI cable (50-pin) to the connector on the A5000/A4000 circuit

board.

• Connect the ﬂat cable from the hard disk (the ﬂat, thin cable) to the corresponding connector on the sam-

pler’s main circuit board (marked “C” in the illustration below, “SCSI CN9” on the circuit board itself).

The connector is “keyed” so that it will only go in one way.

9.Connect the hard disk power cable (long) to one of the power connectors in the A5000/

A4000.

• Connect the hard disk power cable to any of the available power connectors— CN1, CN2, or CN4.

• If no expansion board or ZIP drive is installed, all three connectors will be available. Any of these con-

nectors can be used.

• If at any time you need to disconnect any of these connectors, do so while pressing the release clip on the

plug. Do not apply excessive force.
