Notes: 1. To minimize the possibility of damage to the hard disk drives when you are installing a hard disk drive in a rack model, install the server in the rack before installing the hard disk drives. 2. You do not have to turn off the server to install hot-swap drives in the hot-swap drive bays. However, you must turn off the server when performing any steps that involve installing or removing cables. Working with hot-swap drives The hot-swap drives are attached to a hot-swap hard disk drive backplane. The backplane is a printed circuit board behind the drive bays. For more information about drive bays and drive installation, see "Installing internal drives" on page 44. The low voltage differential (LVD) SCSI hot-swap hard disk drive backplane supports a maximum of six slim-high, hot-swap hard disk drives. 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. Each hot-swap drive has two indicator LEDs (see the User's Guide on the IBM xSeries Documentation CD). If the amber hard disk drive status LED for a drive is lit continuously, that drive is faulty and requires replacement. When the hard disk drive status LED indicates a drive fault, you can replace the drive without turning off the server. For increased security, the hot-swap drives and filler panels are locked in the server by the hot-swap lock bar. The hot-swap lock bar cannot be released, allowing installation and removal of the hot-swap drives and filler panels, unless the key lock on the server side cover is unlocked. Note: All drives being used in the server should have the same speed rating: mixing speed ratings will cause all drives to operate at the lower speed. The hard disk drives that are connected to the standard backplane are attached to channel A. Notes: 1. Table 5 on page 48 lists the SCSI identifiers (IDs) for the standard LVD SCSI backplane and hard disk drives. 2. Cable identifiers are printed on the cables that come with your server and options. Use these identifiers to connect the cables to the correct connectors. 3. For additional information about cabling, see "Cabling an optional SCSI adapter" on page 43 and "System-board option connectors" on page 91 46 IBM xSeries 225 Types 8649: Hardware Maintenance Manual and Troubleshooting Guide
