Model ST173404FC/FCV, Fibre Channel interface disc drive

Publication Number: 83329483, Rev. B, March 2000

Handling precautions/Electrostatic discharge protection

•Disc drives are fragile. Do not drop or jar the drive and 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 circuit board or drive top.

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. Two mounting holes are in each side of the drive and there are four mounting holes in the bottom of the drive. Do not over-tighten or force the screws. You can mount the drive in any orientation. See Figure Figure 1.

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

Figure 1. Sample drive carrier

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.

[1]The drive has a 2.2K ohm resistor in series with this LED driver. Tie the minus side of an external high-efficiency LED (i.e., 2ma) to this pin. Connect the plus side of the LED to +5V.

[2]An external current-limiting resistor is required when connecting an LED to this pin. The minus side of the resistor/LED combination is con- nected to this pin. Connect the plus side to +5V.

Fault LED Signal

The drive activates the fault LED Out signal when:

•the drive detects failure of both ports

•the drive detects an internal failure

•the drive receives the appropriate fault LED command from the host

Active LED signal

The drive activates the active LED signal as indicated below.

Normal command activity	LED status
Spun down and no activity	Slow blink (20% on and 80% off)
Spun down and activity	On
(command executing)
Spun up and no activity	On
Spun up and activity	Off
(command executing)
Spinning up or down	Blinks steadily (50% on and 50% off)
Format in progress	Toggles on/off
(each cylinder change)

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