Removable fan tray assembly with latching features

A fan tray mountable to a chassis, comprising:

• a generally planar fan support member having at least one aperture for allowing passage of air therethrough;
• at least one fan mounted to the fan support member such that the respective at least one fan is in registration with the at least one aperture, the at least one fan having power leads electrically connectable to a power connector;
• a generally planar side member coupled to the fan support member;
• a filter for filtering air passing through the at least one aperture, the filter being supported by a frame removably mounted to the fan support member;
• and
• a locking member pivotally mounted to the side member and pivotable between a first position and a second position, wherein the locking member obstructs removal of the filter frame from the frame support member when in the first position and the locking member does not obstruct the filter frame when in the second position,
• whereby, when the locking member is in the first position and the power connector is connected to the power leads of the at least one fan, the power connector obstructs the movement of the locking member so as to prevent movement of the locking member from the first position to the second position.

A fan tray air baffle system for use with a chassis, comprising:

• a skirt extending downward from said chassis partially enclosing a plenum;
• a generally planar fan support member having a plurality of apertures for allowing passage of air therethrough and a set of four sidewalls surrounding said fan support member forming a fan tray;
• at least two fans mounted to the fan support member, each fan being in registration with a respective one of the plurality of apertures;
• at least one elongated barrier extending from said planar fan support member to a height parallel with a top of said sidewalls and being disposed in a mounting position between the at least two fans;
• and
• at least one baffle disposed across said plenum, said at least one baffle aligned with and abutting said at least one elongated barrier when said fan tray is in a home position, to divide said plenum into a pair of plenums;
• wherein said pair of plenums are adapted to reduce the portion of a current of air produced by at least one fan on a first side of the barrier passing through at least one aperture in registration with at least one corresponding fan on a second side of the barrier when the at least one corresponding fan is not operative.

An electronics enclosure and fan tray assembly adapted to have said fan tray cool electronics in a card cage portion of said electronics enclosure, said card cage enclosed by a backplane, sidewalls, and a card cage door, and said fan tray having a rectangular parallelepiped shape, said assembly comprising:

• a set of flanges attached to a bottom of said sidewalls of said electronics enclosure;
• at least one slam lock disposed on a front panel of said fan tray, a tongue of said at least one slam lock extending toward at least one side of said fan tray;
• at least one opening in at least one sidewall aligned to receive said tongue, wherein said fan tray locks in a home position relative to said electronics enclosure;
• a bottom of said fan tray with at least one aperture to allow entry of air;
• and
• at least one fan, each fan positioned over an aperture;
• wherein said fan tray is adapted to slidably engage said set of flanges of said electronics enclosure.
