INSTALLATION
Steps:
1. Turn off the computer and all attached peripheral equipment, such as printers and monitors.
2. Disconnect the AC power cable from the computer.
3. Remove the screws attaching the computer’s cover, and remove the cover from the system.
4. Remove the drive from the ESD (Electro Static Discharge) bag, carefully placing the drive on your work surface.
5. Configure the disk drive jumpers as necessary. Refer to table below for more details.
6. Remove SCSI terminator resitor packs (2) in all drives on the SCSI bus except for the last drive in the chain.
7. Remove and retain any hardware that may be attached to the selected bay.
8. Connect the cables; align the colored striped edge of the interface cable to pin 1 of the drive SCSI interface connector.
9. Partially insert the drive into the drive bay. Select an unused power connector from the power supply and connect it to the drive. If there are no unused
power connections on the power supply, you can purchase a “Y” cable adapter from your dealer . This connector will allow you to add another power
connection for your new drive.
10. Now that the drives are jumpered, connected, and have power cables attached, secure the drive or the mounting frame with four 6-32x.25 screws.
CAUTION: Do not use screws of excess length when attaching the drive. Damage to the drive’s circuit board could result. The maximum insertion in
bottom holes is .25”, the maximum insertion for side holes is .125”.
