4.2.2 Clearances

For proper cooling, a clearance of 6 millimeters should be provided above and below the carrier surfaces. Adequate airflow is needed in order to meet the operating specifications. Maximum temperatures are speci- fied for critical drive components in Table 15 on page 78.

4.2.3 Mounting

The drive can be mounted with any surface facing down.

The carrier is designed to be plugged into an auto-docking assembly. The auto-docking assembly contains an electrical receptacle that provides connections for D C power, SSA interface signals, and fault sensing and reporting signals (see 5.2, “Carrier Connector” onpage 64). The carrier design allows for positive retention of the carrier in all axes when plugged into the auto-docking assembly. In addition, the carrier retention provides a force to bottom out the carrier auto-docking connector into the auto-docking assembly and main- tain a force of 5 pounds minimum, 40 pounds maximum.

The mating connector should contain two guide pins to align the carrier receptacle during seating. These guide pins are B E R G part number 77693-014 (IBM part number 72G0343) or A M P equivalent part number 1-532808-1 (IBM part number 19G6789). The guide pin length should be 26.04 millimeters while the thread depth depends upon the thickness of the circuit board the connector is mounted to. The guide pins should be tied to the docking assembly frame ground.

Note: The connector pins must be lubricated to insure seating of the carrier into the auto-docking assembly. The type of lubricant recommended is Stauffer CL-920 or equivalent.

WARNING: The drive may be sensitive to user mounting implementation due to frame distortion effects. IBM will provide technical support to assist users to overcome mounting sensitivity.
