Western Digital AC2540 Quick Installation page 3

Mounting Hardware
Inspect the bay to see whether it is a 3.5-inch or 5.25-inch bay. The
Western Digital hard drive fits into a 3.5-inch bay. If installing the
Western Digital hard drive in a 5.25-inch bay, you must install the
5.25-inch mounting hardware that is provided. You might also need
to install the system manufacturer's drive rails. Consult your
operating system manual for installation into a 3.5-inch bay.
Installing the 5.25 Mounting Hardware
This step is not required for hard drive installations into a 3.5-inch
drive bay.
1. Gently place the hard drive horizontally (circuit board side down) on
top of the ESD bag placed on a flat, padded surface.
2. Attach the mounting brackets to the hard drive using the screws
provided. For proper grounding, be sure to use ALL FOUR
screws.

Drive Rails (Optional)
Some computer systems have 5.25-inch drive bays that require
unique sliding drive rails to complete the hard drive installation.
Because each system manufacturer has a different type of drive rail,
rails are not included with Western Digital hard drives.
If your system requires drive rails, contact the computer system
manufacturer. The following list provides phone numbers for
common system manufacturers.

Install Your New Hard Drive
1. Thread the cable through the empty drive bay and slide in the
Western Digital hard drive.
2. Attach the end of the 40-pin interface cable to the 40-pin
connector on the back of the Western Digital hard drive. Match
pin socket 1 on the IDE cable (indicated by a color stripe on the
cable) to pin 1 on the Western Digital hard drive. See Figure 3.
3. Attach the computer system power supply cable to the 4-pin power
connector on the back of the Western Digital hard drive. The
4-pin connector is keyed to ensure proper insertion.
Figure 3. Attaching IDE Cable to the Hard Drive
4. Single Installations: Attach the end of the 40-pin IDE cable from
the Western Digital hard drive to the IDE connector on the
motherboard or controller card. Match pin socket 1 on the IDE
cable (indicated by a color stripe on the cable) to pin 1 on the
motherboard or controller card.
Dual Installations: Connect the two hard drives by using a
three-connector IDE interface cable. A three-connector IDE
interface cable is included in this package. Match the orientation
of pin socket 1 on the 40-pin three- connector IDE cable to pin 1
on the drive connector. See Figure 3.
Tips:
Install single drives at the end of the 40-pin IDE cable. The
40-pin IDE cable should be no longer than 18 inches.
The master/slave is determined by jumper configuration, not
by the order of the drive on the cable.
5. Mount the Western Digital hard drive in the drive bay using the
four mounting screws provided. For proper grounding, be sure to
use ALL FOUR screws.
If an extra power connector is not available, purchase a Y-adapter
from your computer dealer.
6. Check all cable connections. Replace the system cover, but don't
screw it on yet. If you can't get the new drive to work, you may
need to check the connections.
7. Plug in your computer. See the Software Installation section for
hard drive setup instructions.
