Abstract: A method and apparatus are disclosed for managing power to a group of connectors. The individual power limits of the connectors may be selectively increased while still complying with a group power limit. In one embodiment, a group of electronic connectors disposed on a host device each include a power portion and a data portion. A mechanical barrier is moveable into a blocked position for physically blocking at least the power portion of one or more of the electronic connectors while the other electronic connectors in the group remain unblocked. A power controller automatically increases an individual power limit of one or more of the unblocked electronic connectors in response to the mechanical barrier being in the blocked position.

Abstract: Controlling an airflow passing into an electronic component cabinet includes passing an airflow into the electronic component cabinet through a first passage having a first filter, sensing a parameter of the airflow passing through the first passage, detecting a change in the parameter of the first airflow associated with a flow restriction at the first filter, and shifting a first flap from a first position allowing the airflow to pass unrestricted through the first passage, to a second position, wherein the first flap creates a flow restriction for the airflow passing though the first passage, and triggers an actuation mechanism based on the change in parameter of the first airflow. Controlling the airflow further includes opening a second flap that exposes a second passage having a second filter based on the triggering of the switch, and passing an airflow into the electronic component cabinet through the second passage.

Abstract: A tilt adjustment mechanism having an upper housing, a lower housing and a shaft assembly is disclosed. The shaft assembly receives the gears which are pressed on either end of shaft. The shaft fits through locating slots in the lower housing. Each of the gears are activated by internal gears located on each side of the upper housing. The internal gears are integrally formed with the upper housing. The upper housing is hinged on the lower housing and can rotate 20 degrees. The shaft assembly mechanism provides a torsion bar function to insure that the upper housing moves evenly with respect to the lower housing. Even motion in the upwards and downwards directions of the housing is provided by even rotational torsional motion and opposite rotational torsional motion of the shaft assembly of the tilt adjustment mechanism. The shaft assembly mechanism decouples the frictional load in the two different rotational directions about its shaft.
