Power And Signal Cables For Internal Drives - IBM System x3200 Installation Manual

Power and signal cables for internal drives

The server uses cables to connect parallel IDE, simple-swap SATA, and SAS
devices to the power supply and to the system board. (For the location of the
system-board connectors, see the User's Guide on the IBM System x
Documentation CD.) Review the following information before you connect power
and signal cables to internal drives:
v The drives that are preinstalled in the server come with power and signal cables
v When you install a drive, make sure that one of the signal cable drive connectors
v If you have only one IDE device on a cable, it must be set as a master device.
v If two IDE devices are used on a single cable, one must be designated as the
The following cables are provided:
v Power cables: Four-wire power cables connect the drives to the power supply.
v Signal cables: Signal cables are typically flat cables, also called ribbon cables,

is connected to the drive and that the connector at the other end of the signal
cable is connected to the system board.
master device and the other as the subordinate device; otherwise, the server
might not recognize some of the IDE devices. The master and subordinate
designation is determined by switch or jumper settings on each IDE device.
At the end of these cables are plastic connectors that can be attached to
different drives; these connectors vary in size. Use either a four-wire power cable
or SATA power cable with SATA drives, but do not use both at the same time
(use one or the other).
that connect parallel IDE, SATA, SAS, and diskette drives to the system board.
Two or three types of signal cables come with the server:
– IDE: The wider IDE signal cable has three connectors. One of these
connectors is attached to the drive, one is a spare, and the third is attached to
the primary or secondary IDE connector on the system board. The spare
connector can be used to connect an additional IDE drive to the server.
The CD-ROM drive is attached to an ATA 100 signal cable. ATA 100 signal
cables are color-coded. The blue connector is attached to the system board.
The black connector is attached to the master IDE device. The gray middle
connector is attached to the subordinate IDE device.
– (Optional) Diskette drive: The narrower signal cable has two connectors.
One is attached to the diskette drive, and the other is connected to the
connector (FDD1) on the system board.
– Simple-swap SATA: Simple-swap SATA models come with four SATA cables
that are already connected to the system board and the back panel at the rear
of the simple-swap drives.
– Hot-swap SATA: Hot-swap SATA models come with a single data cable that
connects the SAS/SATA controller to the hot-swap backplane. This cable
provides inherent connectivity for the four SATA drives that the server
supports. Therefore, additional cabling is not required for these drives.
– SAS: Hot-swap SAS models come with a single data cable that connects the
SAS/SATA controller to the hot-swap backplane. This cable provides inherent
connectivity for the four SAS drives that the server supports. Therefore,
additional cabling is not required for these drives.
For more information about the requirements for SAS cable and connecting
SAS devices, see the documentation that comes with these devices.
