ST3390N, ST3655N Installation Guide, Rev. A 1

Read before you begin...

Application. Your drive is designed for IBM AT and compatible personal computers, Sun, Macintosh and other SCSI systems.

Turn off the system power before attempting any installation.

Static discharge. Observe the following precautions:

• Keep the drive in its static-shielded bag until you are ready to complete the installation. Do not attach any cables to the drive while it is in its static-shielded bag.

• Handle the drive by its edges or frame.

• Do not touch the I/O connector pins or the circuit board.

• Before handling any components, put on a grounded wrist

strap, or ground yourself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet.

• Use antistatic padding on all work surfaces.

• Avoid static-inducing carpeted areas.

Drive handling. The drive is extremely fragile—handle it with care. Do not attach labels to any part of the drive.

Inspection. Once you are familiar with the handling precautions listed above, inspect the drive. If it appears to be damaged, call your distributor or dealer immediately.

Warranty. See your authorized Seagate Maintenance and repair. Seagate drives do not require mainte-

nance. The head/disc assembly is sealed; if you break the seal, you void the warranty. Seagate customer service centers are the only facilities authorized to repair Seagate drives. Seagate does not sanction any third-party repair facilities.

Shipping. Keep your original box and packing materials for transporting or shipping your drive. The box has a

Approved Package

container voids the warranty. Call your authorized Seagate distributor to purchase additional boxes.

label. Shipping a drive in a nonapproved

distributor or dealer.

Configuring the drive

Select the appropriate drive features by installing or removing jumpers on the drive circuit board according to the instructions in Figure 1 on page 6 and Figure 2 on page 7. Refer to your host adapter documentation for terminator specifications and configuration instructions.

1. Setting the SCSI ID. Each device on the bus must have a unique SCSI ID. If you are installing only one drive, use SCSI ID 0 (no jumper installed). If you install a second drive, you can use any ID (SCSI ID 1 is recommended). SCSI ID 7 is usually reserved for the SCSI host adapter. To set the

ST3390N, ST3655N Installation Guide, Rev. A 3

SCSI ID, install jumpers on the SCSI ID jumper block as shown in Figure 1 on page 6.

2. Installing or removing terminating resistors. SCSI I/O termination consists of three resistor packs, called terminators, that plug into sockets on the printed circuit board. The terminating resistors are shown in Figure 1.

If you are installing only one drive, leave the terminators installed. If you are installing multiple drives, remove the terminators from all drives except the drive connected to the end of the cable.

3. Installing jumpers on the terminator power source jumper block. If you removed the terminating resistors in step 2, install

a jumper on pins 2 and 4 of the terminator power source jumper block shown in Figure 1.

Note. Installing a jumper on pins 2 and 4 of the terminator

power source jumper block does not disconnect the terminating resistors from the circuit. If your application requires no terminating resistors, you must unplug them from the drive circuit board as discussed in step 2.

To select the drive power connector as the termination power source for the resistor packs, install a jumper on pins 1 and 3 of the terminator power source jumper block.

To select the SCSI connector as the termination power source for the resistor packs, install a jumper on pins 1 and 2 of the terminator power source jumper block.

To provide terminator power to the SCSI connector from the drive power connector only, install a jumper on pins 3 and 4 of the terminator power source jumper block.

To provide terminator power to the SCSI connector and the drive terminator packs, install jumpers on pins 1 and 2 and pins 3 and 4 of the terminator power source jumper block.

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.

Fast SCSI SCSI Termination Terminator

specification Install active/passive

termination jumpers

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.
