1 3.5 inch diskette drive 2 CD-ROM drive 3 Media bays 1 and 2 4 Hot-swap hard disk 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 the 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 on the front of the server. If the amber hard-disk status light for a drive is lit continuously, that individual drive is faulty and needs to be replaced. When the hard-disk 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-swapdrive trays come with hot-swap drives. Internal drive bays Internal drives are installed in bays. • Your server comes with one CD-ROM drive and one 3.5-inch, 1.44 MB diskette drive. • The left front bays support 5.25-inch, half-high, removable-media drives. Any two adjacent 5.25-inch, half-high bays can be converted to a single full-high bay. Note: The server EMI integrity and cooling are both protected by having the left front bays covered or occupied. When you install a drive, save the filler panel from the bay, in case you later remove the drive and do not replace it with another. • You cannot install hard disk drives in the left front bays. You can install hot-swap hard disk drives only in the hot-swap hard disk drive bays on the right front side of the server. Installing options 67
