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.

Drive electronics are extremely sensitive to static electricity. Keep the drive in its antistatic container until you are ready to install it. Wear a wrist strap and cable connected to ground. Discharge static from all items near or that will contact the drive. Never use an ohmmeter on any circuit boards.

Turn off the power to the host system during installation.

Always use forced-air ventilation when operating the drive.

Use caution when troubleshooting a unit that has voltages present.

Do not disassemble the drive; doing so voids the warranty.

Return the entire drive for depot service if any part is defective.

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

What you need

Screwdriver and four 6-32 UNC drive mounting screws

Forced-air ventilation to provide adequate drive cooling

Host system with Fibre Channel host adapter or backplane

Installation instructions

1. Mount the drive in the host system carrier or tray

Most Fibre Channel host systems (including enclosures) provide a way to insert the drive using a carrier or tray which allows the drive to be hot- plugged into the system’s Fibre Channel 40-pin single connector attach- ment (FC-SCA).

Mount the drive to the carrier or tray provided by the host system using four 6-32 UNC screws. Do not over-tighten or force the screws. You can mount the drive in any orientation. See Figure 1.

Note. FC drives are designed to be attached to the host system without I/O or power cables.

Note. Figure 1 shows a generic carrier. Most carriers will look different than the one shown. Many are actually small enclosures rather than brackets as shown here.

2. Insert the drive

Slide the carrier or tray into the appropriate bay in your host system. This connects the drive directly to your system’s 40-pin Fibre Channel single connector attachment (FC-SCA). The FC-SCA connector is normally located on a Fibre Channel backpanel.

Note. There are no jumpers or terminators on the drive, and power is sup- plied through the 40-pin connector.

3. Connect LEDs (optional)

Note. This is an optional step. The drive will work fine without the LEDs connected to the drive.

The drive supplies pins that you can use to connect fault and active LEDs. This allows you to monitor drive fault conditions and activity. The actual LED is external to the drive.
