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.

Read the following general information topics to ensure your
drive is installed properly:

• Providing adequate cooling
• Mounting the drive
• Formatting the drive

Providing adequate cooling

The enclosure design must ensure adequate cooling for the
drive. The maximum ambient temperature is 50

o

C (30

o

C for the

rated MTBF). Refer to Figure 2 on page 17 for an illustration
showing suggested air flow patterns.

The drive’s product manual (83329210) describes how to evalu-
ate the air-flow design. The evaluation consists of ensuring that
the case temperatures of certain critical components remain
within acceptable limits during drive operation.

We recommend orienting the drive or directing the air flow in a
way that creates the least amount of air-flow resistance while
providing air flow above the circuit boards and around the head
and disc assembly (HDA). Also, choose the shortest possible
path between the air inlet and exit. This minimizes the distance
traveled by air that is heated by the drive and by other nearby
heat sources.
