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
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.
v When you route a cable, make sure that it does not block the airflow to the rear
of the drives or over the microprocessor or DIMMs.
The following cables are provided:
v 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 IDE
connector on the system board. The spare connector can be used to connect an
additional IDE optical drive or tape drive to the server.
The CD or DVD drive is attached to an ATA 100 signal cable. The blue connector
is attached to the system board. The connector on the other end is attached to
the master IDE device. The middle connector attaches to an optional optical
device or tape drive.
v Simple-swap SATA: The combination signal/power cable connects to the system
board and simple-swap SATA backplate to provide signal and power to the
simple-swap SATA drives.
Simple-swap SATA models come with the combination signal/power cable
connected to the system board and the simple-swap SATA backplate.
Notes:
1. You can install the optional ServeRAID-8k Controller in the simple-swap
SATA models to get RAID level-5 support. If you install the ServeRAID-8k
Controller, you will need to switch the hard disk drive signal cable to a
different connector on the system board and connect a RAID level-5 Enabler
plug to the system board. See “Installing the ServeRAID-8k adapter” on page
57 for information on how to install and cable ServeRAID-8k Controller in
simple-swap SATA models for RAID level-5 support.
2. When you install the optional ServeRAID-8k Controller in the simple-swap
SATA models for RAID support, make sure that you remove the dust shield (if
one is present) from the signal connector on the system board before
installing the signal cable. Carefully grasp the dust shield and pull it out of the
signal connector.
v You can order an optional IBM ServeRAID-MR10is VAULT SAS/SATA Controller
that supports RAID levels 0, 1, 5, 6, 10, 50, and 60. You can install the
ServeRAID-MR10is SAS/SATA controller only in server models with eight 3.5 inch
hot-swap hard disk drives installed. For instructions on how to install the
ServeRAID-MR10is SAS/SATA controller, see “Installing the optional IBM
ServeRAID-MR10is VAULT SAS/SATA Controller” on page 60 for instructions on
how to install this adapter.
Note:
Note: The onboard RAID controller will be disabled by BIOS when the
ServeRAID-MR10is SAS/SATA controller is installed in the server.
v Hot-swap SAS or hot-swap SATA: Hot-swap SAS and hot-swap SATA models
come with a single signal cable and a single power cable that connects to the
system board and the hot-swap SAS/SATA backplane to provide signal and
power to the SAS or SATA drives. If you order the 4-drive backplane option kit to
upgrade to eight drives, the option kit comes with an additional signal cable and
power cable.
Hot-swap SAS and hot-swap SATA models come with the signal cable and power
cable connected to the system board and the hot-swap SAS/SATA backplane.
