Power And Signal Cables For Internal Drives - IBM 436854u - System x3200 M2 5U Mini Tower Server User Manual

Power and signal cables for internal drives

The server uses cables to connect SATA-attached, simple-swap SATA, hot-swap
SAS, and hot-swap SATA devices to the power supply and to the system board.
(See "System-board internal connectors" on page 16 for the locations of
system-board connectors.) 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 When you route a cable, make sure that it does not block the airflow to the rear
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 or a compatible adapter or controller that
you have installed.
of the drives or over the microprocessor or DIMMs.
At the ends 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 SATA attached, SATA, SAS, and diskette drives to the system
board. Two or three types of signal cables come with the server:
– SATA attached (for optical drives): The flat SATA-attached signal cable has
two connectors. One of these connectors is attached to the optical drive, and
one is attached to one of the connectors on the system board.
– (Optional) USB diskette drive: The narrower signal cable has two
connectors. One is attached to the diskette drive, and the other is attached to
the connector (J11) 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 backplate at the rear
of the simple-swap drive cage.
– Hot-swap SAS/SATA: Hot-swap SAS/SATA models come with one or two
(depending on the model) data cables that connect the SAS/SATA controller to
the hot-swap backplane. The data cable provides inherent connectivity for the
SAS or SATA drives that the server supports. Therefore, additional cabling is
not required for these drives.
For more information about the requirements for SAS/SATA cable and
connecting SAS/SATA devices, see the documentation that comes with these
devices.
