Jumper setting
--------------
x = Jumpers set from factory
10-pin and 14-pin version have the same pin definition for pins 1-10.
The 14-pin version has 4 additional pins (11-14)
Master/Slave Jumper
-------------------
1-2 OPEN Master
CLOSED Slave
If only one drive is installed, configure the drive as a master. If
there are two drives installed on the bus, one must be configured as
a master and the other as a slave. No more than two drives can be
connected on the AT bus.
To configure the drive as a slave, install a jumper on pins 1 and 2
of the the 12-pin user configuration jumper block.
To configure the drive as a master, leave pins 1 and 2 of the options
jumper block open.
3-4 Head Configuration
----------------------
3-4 CLOSED 5 Heads
OPEN 7/9 Heads
Slave-Present Jumper
--------------------
5-6 OPEN Slave not installed
CLOSED Slave installed
If both the master and the slave are Swift AT interface drives, you
do not need this jumper. This is because the master can detect the
presence of the slave using the interface DASP-signal state.
If the drives in your application do not implement the DASP-signal,
install the jumper on the master drive only, (The slave drive ignores
this jumper).
To tell the master that a slave is present, install a jumper on pins
5 and 6 of the options jumper block on the master drive.
ECC Jumper
----------
7-8 OPEN 4 ECC Bytes
CLOSED 7 ECC Bytes
This jumper setting selects the number of ECC bytes transferred to or
from the host during read long and write operations. (The media
always uses seven ECC bytes. The jumper only controls the number of
bytes transferred.)
- If you install a jumper on pins 7 and 8 of the options jumper
block, seven ECC bytes are transferred.
- If you do not install a jumper on pins 7 and 8 of the options
jumper block, four ECC bytes are transferred.
Factory Test Jumper
-------------------
9-10 OPEN Normal Operation
CLOSED Factory Test
Pins 9 and 10 are used for testing during the manufacturing process;
they are not for field use.
11-12/13-14 Factory Use
------------------------
Some PWA's have these pins

Swift LED kit 75912397 allows connection to a remote LED.
Swift LED kit 95913369 has an LED for attachment to the system front
bezel or a 5.25-inch frame kit.

UNACCEPTABLE! UNACCEPTABLE!
The drive may be mounted in the following positions:
1. Horizontally, with the drive's PC board on the top drive.
2. Horizontally, with the drive's PC board on the bottom of the
drive.
3. Vertically, on either side.
Do not mount the drive vertically on either end.
For optimum performance, format the drive in the same orientation as
it is be mounted in the host system.
Caution: To avoid potential service problems, observe the following
precautions:
- Handle the drive by the edges or frame. Do not pressure on the top
cover or touch the circuit board.
- Do not remove or cover factory-installed labels. They contain in-
formation needed to service the product.
- Do not put labels over the breather holes on the top surface of
the drive. The breather holes must remain clear to allow air
circulate.
- If a label, oher than a factory-installed label, has been placed
over the breather holes, remove it. Do not poke holes through the
label. This damages the filter underneath, allowing contaminants to
enter the drive.
- Do not use solvents to remove the adhesive residue from drive
labels. Small amounts of solvent may get into the unit and contami-
nate the disc.
- Do not plug a live DC power cable into the drive power connector.
This damages the connector contacts.
