Western Digital AC2540 Installing the 5.25 Mounting Hardware, Drive Rails Optional

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.

System Manufacturers:

AST	817-232-9824
Compaq	713-518-2000
Dell	512-338-4400
Digital	603-884-5111
Gateway 2000	605-232-2000
HP	208-323-2551
IBM	800-IBM4YOU
NEC	415-528-6000
Packard Bell	801-579-0161

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.
