Figure 16. Handle Docking and Ejection System

The handle on the carrier is used for insertion into and extraction from the drawer. It also provides enough force to ensure seating of the carrier electrical receptacle with the mating connector. Referring to Figure 16, with the handle in the S T O P or open position, a carrier inserted into the auto-docking assembly will have the connector guide pins inserted into the carrier receptacle but the connector pins will not be making contact with the carrier receptacle. Moving the carrier handle to the C A M I N position and eventually to the L O C K E D position sets the auto-docking connector with the carrier receptacle and holds the carrier in all the mounting positions listed above. Moving the handle from the L O C K E D position to the E J E C T position provides leverage via the cam surface on the handle acting against the side rails to separate the connector pins from the receptacle.
