Installing the Barracuda 18FC drive

To install a Barracuda 18FC drive, simply plug the drive directly into your system’s Fibre Channel backpanel 40-pin single con- nector attachment (FC-SCA). There are no jumpers or termina- tors on the drive, and power is supplied through the connector. Table 1 on page 25 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

The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature is 50oC (30oC for the rated MTBF). Refer to Figure 2 on page 18 for an illustration showing suggested air flow patterns.

The drive’s product manual (77767524) 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.
