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 t op of the drive.

• 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 hotplugged into the system’s Fibre Channel 40-pin single connector attachment (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.

Figure 1. Sample drive carrier

Note. Fi gure 1 shows a generic carrier . Most carriers will look dif ferent 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. Format the drive

The drive has been low level formatted at the factory. You do not need to perform another low level format on this drive unless you decide to perform certain diagnostics through the host adapter. If you do decide to perform a low level format, do not abort the format as this is likely to make the drive inoperable. A low level format, with verify turned on, may take over six hours to complete.

Protect against power failure or other power interruptions during the format. a. Turn on DC power to the host system. b. Boot the system from a system floppy, CD, or from a previously

installed hard disc drive if there is one.

c. Format the drive. Caution. Formatting a drive erases all user data. Be sure that you under-

stand this principle before formatting any hard disc drive. It is not necessary to format a drive that previously has been used to store data, unless your intention is to erase all user data.

is not responsible for lost user data.

Hot plugging the drive

This drive features hot plugging capabilities which allow you to insert and remove the drive without powering down the host system. Any time a drive is inserted or removed from a Fibre Channel loop, a short loop interruption occurs and the loop resynchronizes automatically to accommodate the added (or removed) drive.

Drive startup options

The drive’s motor will start spinning the discs based on the status of two signals set by the host adapter. These two signals are called Start_1 and Start_2. There are four options as described below.

Option Start_2 Start_1 Motor spin function

1........... Low.......Low ........Motor spins up at DC power on.

2 ........... High ...... Low ........ Motor s pins up when the host adapter sends

the SCSI Start command.

3 ........... Low.......High........ Motor spins up after a delay of 12 seconds

times the physical address of the drive.

4........... High ......High........The drive will not spin up.

Most systems that host only a couple of drives use option 1 to enable all of the drives to start up immediately when power is applied to the drives. Systems hosting larger numbers of drives may be configured to start drives at various times to avoid overloading the capabilities of the host system’s power supply.

If you want to change the startup option for the drive, pleas e refer to the documentation provided with your Fibre Channel host adapter or host system.

Troubleshooting

• Drive does not spin up. Remove and then reinsert the drive into the

drive bay on the host-supplied carrier or tray. Make sure the drive makes firm contact with the host’s FC backpanel connector. Also, check the drive startup options for the Start_1 and Start_2 signals controlled from your host adapter. See “Drive Startup Options” above for the four possible startup options.

• Computer does not seem to recognize t he drive. Verify that the drive

is enabled by the FC host adapter setup utility.
