Abstract:

A computer system is provided with a chassis at least partially defining an interior and an access opening. The computer system is also provided with an interface connector mounted within or adjacent to the chassis and oriented to face the interior of the chassis. A circuit board assembly is configured for insertion into and removal from the interior of the chassis through the access opening and along an insertion axis, wherein the circuit board assembly has a connector oriented for engagement with the interface connector. The computer system also includes a mounting assembly positioned to facilitate engagement of the connector of the circuit board assembly to the interface connector along a connection access angled with respect to the insertion axis. The mounting assembly has a tray mounted for cam-activated movement with respect to the chassis along the connection axis, wherein the tray is configured with channels to receive rails of the circuit board assembly along the insertion axis and to move the circuit board assembly relative to the chassis along the connection axis to join the circuit board and interface connectors.

Abstract:

A fan tray assembly. The assembly comprises a module, housing electronic components that require cooling, and one or more fan trays having fans that direct a cooling air flow through the module. The assembly facilitates easy and fast removal and replacement of the fan trays with respect to the module. These desirable attributes are achieved by five main features of the assembly: (1) a retaining slot-and-tab engagement pivotally attaching each fan tray to one side of the module, (2) a channel-in-track automatically aligning each fan tray as it closes against the module, (3) a leaf spring releasably locking each fan tray into a closed position, (4) a floating power-and-signal connector on each fan tray electrically and mechanically engaging a corresponding receptacle on the module, and (5) a pull ring facilitating manipulation of each fan tray.
