Internal Drive Bays; Installing A Hot-Swap Hard Disk Drive - IBM 866631Y - Netfinity 7100 - 8666 Hardware Maintenance Manual

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.
v The server comes with one integrated drive electronics (IDE) CD-ROM drive and
one 3.5-inch, 1.44 MB diskette drive.
v 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.
v 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.
v If you are installing a device with a 50-pin connector in one of the left front
bays, you will need a 68-to-50-pin converter (option number 32G3925).
v Your server supports ten 1-inch (26 mm) slim-high or seven 1.6-inch (42 mm)
half-high, 3.5-inch hot-swap hard disk drives in the hot-swap bays.
v The hot-swap bays connect to a hard disk drive (HDD) backplane. The backplane
is a printed circuit board behind the bays.
Some drives have a special interface called small computer system interface, or SCSI.
Using this interface, you can attach multiple drives to a single SCSI controller.
Notes:
1. Any information about SCSI drives also applies to other SCSI devices, such as
scanners and printers.
2. If you plan to install both internal and external SCSI devices, you must follow
the instructions in "Connecting external options" on page 65, in addition to the
instructions in this section.
An additional 16-bit, two-drop SCSI cable comes with the server. It is located in the
bottom of the server media bay and is restrained with a cable clamp.
If you want to install SCSI devices in the removable media bays:
1. Locate the internal SCSI connector on the power backplane.
2. Use the 16-bit two-drop SCSI cable located in the bottom of the server media
bay.
3. Connect the SCSI device(s) in the removable media bay to the internal SCSI
connector on the power backplane.
Note: If you are installing a 5.25-inch device, you can obtain an optional SCSI
adapter to control the SCSI hot-swap backplane.
