Step 2: Prepare for installation
Opening your computer
1. Turn the system off.
2. Unplug the power cord from the wall outlet.
3. Remove all cables from the back of your computer, labeling them if necessary.
4. Remove the cover from your computer. (Consult your user's guide for instructions if needed.)
Unpackaging your hard drive
1. Remove the drive from the anti-static package that it was shipped in.
2. Handle the drive by the sides only.
3. Do not touch the main computer chip board.
4. Do not drop. A drop from only 1/4 inch could permanently damage your hard drive.
5. If available, use an ESD (Electronic Static Discharge) wrist strap while handling your drive.
6. Place the drive carefully on a static free area.
Step 3: Jumper settings
The jumper settings are found on the hard drive on the opposite end of the interface connector (see
diagram page 12). They are physical settings that must be changed for different uses of a hard drive.
SCSI ID Jumpers
Each SCSI device will need to have its own SCSI ID. You can use ID 0 through ID 15, reserving ID 7 for
your controller card. Follow the table below to set an ID on your SCSI drive.
