3) Tighten the captive screw on the cable-management-arm bracket to the server. 4) Reinstall the fan in fan bay 7. 30. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 106. Installing internal drives If you add different types of drives, your system can read multiple types of media and store more data. Several types of drives are available, such as: v Diskette v Hard disk v CD-ROM v Tape, including digital linear tape (DLT), super digital linear tape (SDLT), and linear tape-open (LTO) Note: The server supports both internal and external tape drives. Your server contains hardware that enables you to replace a failed hard disk drive without turning off the server. Therefore, you have the advantage of continuing to operate your system while a hard disk drive is removed or installed. These drives are known as hot-swap drives. Each hot-swap drive has two indicator lights (see "Server controls and indicators" on page 4). If the amber hard disk drive status light for a drive is lit continuously, that individual drive is faulty and requires replacement. When the hard disk drive status light indicates a drive fault, you can replace a hot-swap drive without turning off the server. Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive tray. The drive must have a single connector attachment (SCA) connector. Hot-swap-drive trays come with hot-swap drives. Internal drive bays Internal drives are installed in bays. The following illustration identifies the bays for the tower and rack models. Standard drive cage, hot-swap drive bays 1 - 6 Optional drive cage, hot-swap drive bays 7 - 12 (Optional SCSI backplane required) Non-hot-swap drive bay A Non-hot-swap drive bay B Non-hot-swap drive bay C Non-hot-swap drive bay D v Your server comes with one integrated drive electronics (IDE) CD-ROM drive and one 3.5-inch, 1.44 MB diskette drive. v The CD-ROM drive bay (bay B, right front) supports 5.25-inch, half-high, removable-media drives. A CD-ROM drive comes preinstalled in the server. Chapter 4. Customer replaceable units 73
