Abstract
A gantry is disclosed that mounts on rails within a server rack. The gantry provides for the stable and repeatable placement of a measurement probe that is oriented to determine the sag of a server by measuring the distances along the Z-axis from the probe to a server at different locations in a XY plane defined by the gantry.
Claims20
An apparatus including:
- a frame including a first elongated member and first mounting points on a first side and a second elongated member and second mounting points on a second side parallel to the first side, the first and second elongated members lying in a first plane defined by a first axis perpendicular to the first and second elongated members and a second axis parallel to the first and second elongated members;
- a first cross member connected between the first elongated member and the second elongated member and movable with respect to the first and second elongated members parallel to the second axis;
- a first bracket connected to the first cross member and moveable along the first cross member between the first and second elongated members;
- and
- a first range finder connected to the first bracket and oriented parallel to a third axis perpendicular to the first plane, the range finder providing data indicating a distance along the third axis.

A method for measuring chassis sag or bow, the method including:
- positioning a frame in a rack, the frame having a first range finder that is at least one of slidably or rotatably mounted on an elongated frame cross-member, the elongated frame cross-member being in a first position with respect to the frame and slidable within a plane parallel to the frame, the first range finder being configured to measure a first distance relative to the first range finder and a first chassis installed in the rack, the first distance being measured in one of a first direction perpendicular to the plane or a second direction perpendicular to the plane;
- determining a first position of the first range finder in the plane;
- measuring the first distance relative to the first range finder and the first chassis in one of the first direction or the second direction;
- and
- determining, using the first distance, at least one of a first sag value or a first bow value of the first chassis at the first position.
