Jumper Setting
==============
Jumpers are used for drive address setting, write cache disabling and
auto re-allocation disabling.
Jumper position and the function are as shown below. Pin pitch is
2mm.

NOTES
1. Jumpers for JP1, 2, and 3 should not be selected concurrently.
2. JP1 is for Master, JP2 is for Slave, JP3 is for Cable Selection
mode.
3. To enable Cable Selection mode, the JP3 jumper must be installed.
In the Cable Selection mode, the drive address is determined as
follows:
- When CSEL signal (pin 28) is grounded or at a low level, the
drive address is 0 (master).
- When CSEL signal is open or at high level, the drive address
is 1 (slave).
4. Position JP4, JP6 and JP7 are reserved.
5. A jumper for JP5 is used to disable write-cache (default).
Write cache jumper is checked during the initial POR check. Write
cache is disabled when a jumper is fitted and in this case a
'Set features'command to switch Write cache 'on'or 'off' will be
aborted by the drive.
Default Setting
---------------
The default jumper setting at shipment is as follows.

The drive will operate in all axis (6 directions).
The maximum allowable penetration of the mounting screws is 1 3.5mm
2 6mm.
The recommended mounting screw torque is 3 0.5 [KgF.cm].
Identification Labels
---------------------
The following labels are affixed to every hard disk drive shipped
from the manufacturing location in accordance with appropriate hard
disk drive assembly drawing.
- A label contaning the IBM logo, IBM part number and the statement
"Made by IBM Japan Ltd.".
- A label containing the drive model number, date code, formatted
capacity, place of manufacture, and UL/CSA/TUV logos.
- A bar code label containing the drive serial number.
- An user designed label per agreement.
The labels may be integrated with the other labels.
Cabling
-------
The maximum cable length from the host system to the HDD, plus the
circuit pattern length in the host system, cannot exceed 18
inches (45.7 cm). For higher data transfer application (>8.3MB/sec)
the cable length should be shorter than 18 inches (45.7cm) since data
transfer characteristics depends on the driver circuits of the system
and hard drive, and or cabling.
Connectors
----------
There is a choice of 2 power connections to this drive. One DC power
connector is designed to mate with AMP part 1-480424-0 (using AMP
pins P/N 350078-4). The other (3 pin) DC power connector is designed
to mate with MOLEX 5480-03 (using MOLEX pins 5479). Equivalent
connectors may be used. Pin assignments are shown below.
+-----+ +-------+
|3 2 1| |4 3 2 1|
+-----+ +-------+
| | +- +5V | | | +-- +12V
| +--- +12V | | +---- GND
+----- GND | +------ GND
+-------- +5V
AT Signal Connector
-------------------
The AT signal connector is a 40-pin connector.
The drive uses single-ended drivers and receivers. The connector is
designed to mate with 3M part 3417-7000 or equivalent.
NOTE
It is intended that the hard disk drive should only be in electrical
contact with the chassis of the PC at a designated set of mounting
holes. Other electrical contact may degrade error rate performance.
As a result of this it is recommended that there should be no metal
contact to the hard disk drive except at the mounting holes or the
side rails into which the mounting holes tapped.

Automatic Power Down Sequence
-----------------------------
A hard reset will disable the automatic power down sequence.
Format Track
------------
A drive will not perform a physical format. Instead it will simply
write a data pattern of all zeros to the sectors which have been
specified by the Format Track command. LBA mode for format track is
not supported.
