[. . . ] CAUTION: Before you perform this procedure, see "Safety First-- For You and Your Computer. " NOTICE: Before disconnecting a device from the computer, wait 10 to 20 seconds after disconnecting the computer from its electrical outlet. Before removing a component from the system board, verify that the standby power light on the system board has turned off. To locate this light, see "System Board Components. " 1 Turn off the computer and devices, disconnect them from their electrical outlets, and wait 10 to 20 seconds, lay the computer on its right side, and open the computer cover. If you are replacing a drive that is already installed in the computer, continue with step 3. If you are installing a new drive, go to step 5. Disconnect the DC power cable and interface cable from the back of the drive you are replacing. Remove the drive from the chassis drive bay. a b 2 3 4 Squeeze together the tabs at each side of the drive to disengage the drive bracket from the chassis. Slide the drive bracket upward, and remove it from the chassis (see the following figure). 67 w w w. c o m Removing a Hard Dr ive 5 Unpack the replacement drive and prepare it for installation. NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer. See the documentation that accompanied the drive to verify that the drive is configured for your computer. Change any settings necessary for your configuration. 6 If the replacement drive does not have bracket rails attached, remove the rails from the old drive by removing the four screws that secure the rails to the drive. Then attach the bracket rails to the replacement drive (see the following figure). 68 NOTE: If you are not replacing an existing drive and the new drive does not have bracket rails attached, install the extra rail set that is located inside your computer in an empty drive bay. Refer to the documentation in your drive upgrade kit for information on setting devices to the Cable Select jumper position. General Guidelines With the two EIDE interface connectors on the system board, your computer can support up to four EIDE drives: · · The primary EIDE system-board connector should be cabled to EIDE hard drives The secondary EIDE connector should be cabled to EIDE CD, DVD, tape, DAT, and zip drives To locate the EIDE interface connectors on the system board, see "System Board Components" or "Interior Service Label. " Each EIDE interface connector on the system board supports the following: · · · · Two devices, master and slave LBA PIO Mode 3 and Mode 4 Ultra ATA/100 (backward-compatible with ATA/66 and ATA/33) EIDE Cables To transfer data at full speed, Ultra ATA/100 hard drives require an 80conductor cable like that used with ATA/66 drives. The 80-conductor cable has a 40-pin connector like the ATA/33 cable, but it has twice as many wires within the cable. If you use an ATA/33 cable with Ultra ATA/100 hard drives, the drives will operate properly, but data will transfer at ATA/33 speeds. 74 NOTICE: Dell recommends that you use only EIDE cables purchased from Dell. Cables purchased elsewhere are not guaranteed to work with Dell computers. SCSI Device Installation Guidelines This section describes how to configure and install SCSI devices in your computer. To install a SCSI device, you can use one or both of the following SCSI controllers: · The SCSI connector on the system board. To locate the SCSI system board connector, see "System Board Components" or "Interior Service Label. " NOTE: The system board SCSI controller will support hard drives only. Do not connect CD or DVD drives, tape drives, DAT drives, and so on. An add-in SCSI controller can be installed in your computer for this purpose. · A SCSI controller card installed in your computer. SCSI ID Numbers Internal SCSI devices must have a unique SCSI ID number from 0 to 15. If you are using the SCSI connector on the system board and a SCSI controller card installed in your computer, you will have two separate SCSI buses operating. Each SCSI bus will have a set of SCSI ID numbers from 0 to 15. When SCSI devices are shipped from Dell, the default SCSI ID numbers for are assigned as follows: Default SCSI ID Settings System Board Controller Device Controller Boot hard drive ID 7 0 Optional Controller Card Device Controller Boot hard drive CD or DVD drive tape or DAT drive ID 7 0 5 6 NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number. 75 w w w. [. . . ] c o m NOTICE: If you use a blunt, nonconductive object to pry the battery out of its socket, be careful not to touch the system board with the object. Be sure that the object is inserted between the battery and the socket before you attempt to pry out the battery. Otherwise, you may damage the system board. Pry the battery out of its socket with your fingers or with a blunt, nonconductive object, such as a plastic screwdriver. 5 Install the new battery. Orient the battery with the side labeled "+" facing up (see the following figure). [. . . ]
