4. Installing jumpers on the active/passive termination

jumper block. If you removed the terminating resistors from

the drive according to the instructions in step 2, skip this step.

If you are either:

• using Fast SCSI transfer rates, or

•

not

using Fast SCSI transfer rates, and both ends of the I/O

cable are terminated by resistors of equal value,

use

active

termination by installing a jumper on pins 1 and 2

of the active/passive termination jumper block, as specified in

the following table.

Pins 1 and 2

Pins 2 and 4

Pins 5 and 6

If the host adapter contains 220/330-ohm resistors that cannot

be removed and replaced with 110-ohm resistors, set the drive

termination power to 220/330 ohms. Remove the jumper from

pins 1 and 2 and install jumpers on pins 2 and 4 and pins 5

and 6 of the active/passive termination jumper block. Then,

replace the 110-ohm terminators provided with the drive with

220/330-ohm terminators.
