Electrostatic discharge protection Caution.
2 Cheetah 9FC Installation Guide, Rev. A grounded to avoid potentially damaging static discharges. • Do not remove any circuit boards from the drive. • Never use an ohmmeter on any circuit boards. • When installing the drive on a carrier or tray, discharge the static electricity from the carrier or tray prior to inserting it into the system. Important safety information and precautions Caution. Use forced-air ventilation when bench-testing the drive to ensure proper cooling of drive components.
Cheetah 9FC Installation Guide, Rev. A 3 • Follow the precautions listed above in “Electrostatic discharge protection.” • Do not remove any circuit boards from the drive chassis. Return the entire drive for depot repair if any circuit board is defective. Removal of circuit boards by personnel not performing depot repair will damage components and may void the warranty. • Do not remove the head and disc assembly (HDA) from the drive. Return the entire drive for depot repair if the HDA is defective.

Cheetah 9FC Installation Guide, Rev. A 13 General description Cheetah 9FC disc drives are high-speed, random-access digitaldata storage devices designed to be used within a host system with a Fibre Channel-Arbitrated Loop peripheral interface. The drive is a component for installation in an enclosure designed for the drive. The disc drive must receive adequate cooling (refer to “Providing adequate cooling”) and it must be sufficiently grounded and shielded from emissions.

Cheetah 9FC Installation Guide, Rev. A 15 Installing the Cheetah 9FC drive To install a Cheetah 9FC drive, simply plug the drive directly into your system’s Fibre Channel backpanel 40-pin single connector attachment (FC-SCA). There are no jumpers or terminators on the drive, and power is supplied through the connector. Table 1 on page 24 lists the pin descriptions of the 40-pin FC-SCA.
16 Cheetah 9FC Installation Guide, Rev. A Figure 2 shows one design approach with one or more fans used to generate air flow. The air-flow pattern can be created by the fans either pushing or drawing air. The overall flow pattern must be directed from side to side in most FC-SCA systems. Kühlung des Systems Die Gehäusekonstruktion muß eine ausreichende Kühlung des Laufwerkes gewährleisten. Die Umgebungstemperatur darf maximal 50oC betragen (30oC für der MTBF).

Air flows in the direction shown or in reverse direction (side to side) Under unit Figure 2: Suggested air flow Abbildung 2.
18 Cheetah 9FC Installation Guide, Rev. A Mounting the drive Do not touch the connector pins or any components on the control board without observing static-discharge precautions. Always handle the drive by the frame only. You may mount the drive in any orientation (horizontally, vertically, or any combination thereof); however, you must ensure that the drive receives adequate air flow for cooling. Mount the drive to the host system’s chassis using four 6-32 UNC screws.

Gemessen von der Außenfläche des Gehäuses dürfen die Schrauben maximal 3,81 mm in die Befestigungslöcher des Gehüuses hineinragen. Die Schrauben müssen gleichmäßig, jedoch nicht zu fest, angezogen werden. Wenn sich eine Schraube nicht ohne Widerstand einschrauben läßt, sind die Gewinde nicht korrekt aneinander ausgerichtet.

Cheetah 9FC Installation Guide, Rev. A 21 Inserting the drive Most systems 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 attachment (FC-SCA). Refer to your system documentation about the method they provide and follow their instructions. When installing the drive on a carrier or tray, discharge the static electricity from the carrier or tray prior to inserting it into the system.
22 Cheetah 9FC Installation Guide, Rev. A Enabling write cache Write caching is a feature that allows the drive to transfer write data to its own cache, tell the controller that the task is complete, and then actually complete the write at a later time. This improves write performance by freeing the CPU to go on to its next command. Warning.
