Caution!

Electrostatic discharge (ESD) can damage disk drives and other components. The server can withstand normal levels of ESD while you hot-swap hard disk drives. Performing all procedures in this manual at an ESD-protected workstation. If one is not available, wear an antistatic wrist strap attached to chassis ground when handling components.

Caution!

If you install high-power drives, you must also install additional system fans. See “Installing Fans for High- Power Drives” on page 57.

10.Replace the access panel, see “Closing the System” on page 7.

11.Close the front door.

SCSI Hard Disk Drives

The system supports a variety of SCSI devices. As shipped from the supplier, the system might contain no hard disk drives. Contact your sales representative or dealer for a list of approved SCSI devices. If you install 10,000 rpm SCSI hard drives, you must install heat sinks on the drives and additional fans in the chassis. See the sections below for specific instructions.

Installing Heatsinks on High-Power Drives

If you plan to use SCSI drives whose power exceeds 15 watts, you must install heatsinks on those drives.

To Install Heatsinks on Hard Drives

1.Position each heatsink (Figure 19) so that the three screw holes in the heatsink align with the corresponding holes in the hard drive. The holes are placed so that you can position the heatsink in only one way: with the fins extending along the side and the top of the hard drive.
