The easiest way to install your drive

Most blade servers are designed to make it possible to easily replace the hard drive. Refer to your system’s user manual for the location of the hard drive compartment and the specific instructions regarding replacement.

Caution. Special training or tools may be needed to service some blade servers.

Refer to your system manufacturer’s support website for the most up-to- date information. Read and follow all instructions regarding the proper steps to be taken when replacing the hard drive.

What you need

•A Phillips screwdriver

•Existing drive mounting screws

•Existing blade server drive mounting framework, cage, or tray

•ATA interface adapter (built into blade servers)

Handling precautions/electrostatic discharge protection

•Disc drives are fragile. Do not drop or jar the drive. Handle the drive only by the edges or frame. Keep the drive in the electrostatic discharge (ESD) bag until you are ready to install it to minimize handling damage.

•Drive electronics are extremely sensitive to static electricity. While installing the drive, wear a wrist strap and cable connected to ground.

•Turn off the power to the blade server during installation. In most blade server host systems, you do not need to shut down the entire system chassis itself, just power to the blade server itself. Refer to the system’s documentation for information specific to your particular system.

•Do not disassemble the drive. Doing so voids the warranty. See the war- ranty information on page 2.

•Do not apply pressure or attach labels to the circuit board or to the top of the drive.

Replacing the existing hard drive

Each system has its own unique hard drive compartment. Refer to your system manual to locate the hard drive compartment and for instructions on removing and replacing the hard drive.

Warning. Ensure that power to the drive is removed or turned off. In a blade server, this typically means turning off power to the blade server itself, not the host chassis.

Note. This drive is designed for a blade server that supplies interface sig- nals and +5V power through a single 44-pin connector. Most blade servers have a fixed connector that attaches directly to the drive.

Some blade servers allow two drives to be installed and setup in a mirrored RAID configuration. If this is your situation, ensure that the storage capaci- ties and speeds of the two drives are identical to avoid potential perfor- mance and reliability problems.

Setting the jumpers

Refer to the jumper settings in Figure 1 or on your drive label to configure the drive for your system. Jumper settings can also be accessed online from our web site at www.seagate.com.

Master or single drive: Use the options jumper block shown in Figure 1 to configure the drive for operation. This jumper block is the 4-pin header adjacent to pins 1 and 2 of the I/O signal pins.

Note. For blade server operation, use cable select (default) or master.

Drive mounting

You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 2 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:

•Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.

•Use only M3 UNC mounting screws. (Reusing the existing screws may be acceptable provided the maximum screw penetration depth of 0.098 inches is not exceeded.)

•Gently tighten the mounting screws (maximum torque: 4.0 in-lb).

•Four (4) threads (0.080 inches) minimum screw engagement recom-
