Power and signal cables for internal drives<br />
The server uses cables to connect SATA attached, simple-swap SATA, hot-swap<br />
SATA and hot-swap SAS devices to the power supply and to the system board.<br />
(See “System-board internal connectors” on page 24 for the location of<br />
system-board connectors.) Review the following information before connecting<br />
power and signal cables to internal drives:<br />
v The drives that are preinstalled in the server come with power and signal cables<br />
attached. If you replace any drives, remember which cable is attached to which<br />
drive.<br />
v When you install a drive, make sure that one of the signal cable drive connectors<br />
is connected to the drive and that the connector at the other end of the signal<br />
cable is connected to the system board or a compatible adapter or controller that<br />
you have installed.<br />
v When you route a cable, make sure that it does not block the airflow to the rear<br />
of the drives or over the microprocessor or DIMMs.<br />
The following cables are provided:<br />
v Power cables: Four-wire power cables connect the drives to the power supply.<br />
At the ends of these cables are plastic connectors that can be attached to<br />
different drives; these connectors vary in size. Use either a four-wire power cable<br />
or SATA power cable with SATA drives, but do not use both at the same time<br />
(use one or the other).<br />
v Signal cables: Signal cables are typically flat cables, also called ribbon cables,<br />
that connect SATA attached, SATA and SAS to the system board. Two or three<br />
types of signal cables come with the server:<br />
– SATA attached (for optical drives): The flat SATA-attached signal cable has<br />
two connectors. One of these connectors is attached to the optical drive, and<br />
one is attached to one of the connectors on the system board.<br />
– Simple-swap SATA: Simple-swap SATA models come with four SATA cables<br />
that are already connected to the system board and the backplate at the rear<br />
of the simple-swap drive cage.<br />
– Hot-swap SAS/SATA: Hot-swap SAS/SATA models come with one or two<br />
(depending on the model) data cables that connect the SAS/SATA controller to<br />
the hot-swap backplane. The data cable provides inherent connectivity for the<br />
SAS or SATA drives that the server supports. Therefore, additional cabling is<br />
not required for these drives.<br />
For more information about the requirements for SAS/SATA cables and connecting<br />
SAS/SATA devices, see the documentation that comes with these devices.<br />
