Electromagnetic interference (EMI) considerations
The drive models described herein, as delivered, are designed
for system integration and installation into a suitable enclosure
prior to use. As such, the drive models described herein are
supplied as subassemblies and are not subject to Subpart J of
Part 15 of the FCC Rules and Regulations nor the Radio
Interference Regulations of the Canadian Department of Communications. However, the units have been tested using proper
shielding and grounding and found to be compliant with the
Class A limits of the FCC Rules and the Regulations of the
Canadian Department of Communications.
2 Hawk 2XL Family Installation Guide, Rev. C
_______________________________________________________________________________________________________________________
The physical design characteristics of the drive models described herein, serve to minimize EMI radiation when installed
in an enclosure that provides reasonable shielding. As such, the
drive(s) are capable of meeting the Class B limits of the FCC
Rules and the Regulations of the Canadian Department of
Communications.
Note. It is the end users' responsibility to assure that the drive
models described herein meet the appropriate EMI requirements of their system. Shielded I/O cables may be
required if the enclosure does not provide adequate
shielding. If I/O cables are external to the enclosure,
shielded cables should be used, with the shields grounded
to the enclosure or to the host controller, but not both.
The equipment is designed to provide reasonable protection
against such interference in a residential installation. However,
there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause interference
to radio or television, which can be determined by turning the
equipment on and off, you are encouraged to try one or more of
the following corrective measures:
• Reorient the receiving antenna.
• Move the device to one side or the other of the radio or TV.
• Plug the computer into a different AC power outlet so that the
receiver and computer are on different branch outlets. That is,
circuits controlled by different circuit breakers.
If necessary you should consult your dealer or an experienced
radio/television technician for additional suggestions.

Drive configuration
You can easily install your new Seagate disc drive as your first
ever hard drive, a replacement or as a second driv e in a computer system with an existing hard disc drive.
Installation involves the following steps:
• Drive configuration
• Mounting
• Informing the computer about your drive and how you want it
divided into partitions.
Before you physically mount your new disc drive in your computer, you need to check the jumper plug settings that determine how the drive operates. Ref er to Table 1 to find the Figure
specified applicable to your model drive for the particular configuration functions of interest. Note that there are some connector pins sticking out from the drive's printed circuit board
(PCB) that are labeled J2 and J6 (called "jumper plug headers").
Model "W" additionally has J1-Auxiliary. Some systems may
have a cable connected to J1-Auxiliary that allows remote setting of drive ID by switches or within the computer logic. It also
provides a connection to a remote drive activity LED. Jumpers
may be used on J1-Auxiliary.
Note the small jumper plugs connected across pairs of pins in
some places on these connectors (Figures 3a through 3e show
these jumper plugs enlarged).
Hawk 2XL Family Installation Guide, Rev. C 11
_______________________________________________________________________________________________________________________
Caution. Note that the jumper plugs used on J2 are shaped
differently and are smaller than those used on J6 or
J1-Auxiliary. Do not use J2 plugs on J6 or J1-Auxiliary as this will damage the internal contacts so they
will not subsequently stay on J2.
The presence or absence of these jumper plugs in various
places gives your drive information about how it is to operate in
your system specifically. Each figure shows a diagram of one
of these jumper headers, together with a brief description of
the operational feature each jumper position controls.
If this is your first hard drive, or if it replaces your existing hard
drive, you may not need to reposition any jumpers. However,
check the figures against your drive to see if it is configured as
it should be for your system. Consult your computer documentation for information on configuring your drive. Your dealer is
the best source for help on this. Seagate also provides support
service for customers if your dealer can't help.
Set Drive ID
Look at Figures 3a, 3b or 3c. If your new drive will be the only
hard drive, assign it as "Drive ID 0," which requires no drive ID
jumpers installed. If y our new drive is to be a second hard drive,
assign it as "Drive ID 1" by placing one of the extra jumper
plugs supplied in the enclosed plastic bag (one of the larger
plugs) on the "Drive ID 1" position, as shown in the figure. Do
not remove cover from area shown shaded in the figure.
Double check drive ID settings for your drive or drives.

("X" means the function selection can be made with jumpers on
that connector;
"Y" means the signal is available to host through that connec-
tor).
Notes[ ] for Table 1:
[1] Use either J6 or J1-Aux, but not both.
[2] I/O connector J1 plugs directly into host. No jumper can be
installed on J1. The host supplies the logic state of these
function signals; causing the selection of these functions.
[3] The host can drive a remotely located Drive Activity LED
using this signal.
[4] Use either J1 or J6, but not both.
[5] Jumper plugs can be used on J1-Auxiliary pins 1-2, 3-4, 5-
6 and 7-8 to set drive ID if desired, but usually a connector/
cable is plugged to J1-Auxiliary to run these signals to the
host for remote ID selection.
[6] The host selects drive ID through J1.
