## Background
BACKGROUND
The present invention relates to an apparatus and method for rack installation, and more specifically, to an apparatus for rack installation with integrated guidance, protective and weight distribution features.
Electronic equipment, such as computers or servers, may be installed in racks to provide modularity and flexibility in an organized and compact assembly. For example, data centers may have hundreds of racks arranged within large rooms, where several servers may be mounted in each rack. The racks may be organized in rows and arranged closely to one another to utilize available floor space. Thus, installing and moving the racks may be a complex task. The racks, including electronics hardware, may be very heavy, making movement and installation of the racks more difficult.
In some cases, the racks may have to be arranged and installed in a certain order due to space and/or wiring constraints. For example, in a situation where six racks are to be installed in a row adjacent to one another, the first and second racks are installed in the first and sixth positions in the row in a first step. The remaining racks are installed in similar fashion, where the third and fourth positions (i.e., most central positions) in the row are installed last. For data centers where the racks are to be tightly arranged and spaced a small distance apart, an outer rack placement that is misplaced by a small amount may adversely affect a subsequent rack installation at the row's center. After placement of the rack on the floor, feet may be used to support the racks, where the weight of the racks may cause damage to the floor due to the concentrated load from the feet to the floor.

DETAILED DESCRIPTION
Large racks of electronic equipment, such as server racks, are difficult and awkward to move, but are often positioned in close proximity to one another to efficiently utilize floor space. For example, data centers have rooms with dozens of server racks arranged in rows within where the racks are positioned adjacent to one another. Properly aligning and spacing the racks during installation and replacement can be challenging. In an embodiment, an integrated electronics rack installation apparatus improves accuracy of rack positioning to enhance installation efficiency while also protecting adjacent racks and the floor beneath the installation apparatus.
Installing the racks on elevated floors of the data center room may involve temporarily arranging a path of protective sheets on the floor for rolling of the racks to the desired location in the room. The racks typically include rolling members, such as casters, that support the racks to enable movement. In some cases, the rolling members are elevated or removed after the rack is positioned and the racks are supported by feet at the rack's base. The protective sheets protect the elevated floors from damage as the heavy racks, weighing up to 8,000 pounds, are rolled across the floor. It is also desirable to position the racks in a manner that distributes the rack weight across the floor surface to reduce impact on the floor. Once the rack is at the final location for installation, it is desirable to align and properly space the rack relative to other racks to ensure uniformity and optimal utilization of floor space. Further, in some cases the racks are not installed in a consecutive fashion, rather, the racks are installed from the outside inward along a row. This installation technique requires precision and uniformity when positioning the racks to ensure proper space is provided for the innermost (center) racks. Further, when installing and removing the racks from the tight space between other racks, it is desirable to maintain control of the racks to prevent damage to adjacent racks. Embodiments simplify the rack installation process by providing a single apparatus to be placed on a desired floor location that enables precise rack positioning using guide features, protects equipment (i.e., adjacent racks), protects the floor with a durable mat and also allows for proper weight (i.e., load) distribution via a support structure.
With reference now to FIG. 1 and FIG. 2, an embodiment of an integrated installation apparatus 100 is shown for positioning an electronics rack on a surface, such as a data center floor for example. The integrated installation apparatus 100 includes a mat 102 with guide members or guides 104 arranged substantially parallel to each other on the mat 102. A support structure, such as elongated members 106, is arranged on the mat 102 to distribute the rack's weight over a surface area of the mat 102. In an embodiment, the guides 104 also provide support and weight distribution properties. In other embodiments, additional support members may be positioned on the mat 102 to enhance weight distribution. In an embodiment, the elongated members 106 are substantially flat members of a selected thickness to support the rack. In one embodiment, the elongated members 106 are arranged substantially parallel to each other and substantially perpendicular to guides 104. After the rack is positioned in a selected position on the mat 102, the rolling members are elevated as the feet are lowered from the rack to support and secure the rack in place. Exemplary rack feet receptacles on the elongated members 106 are depicted by element 107. The guides 104 may be any suitable shape, such as an L-shaped cross-section similar to angle bars, to receive and guide the rack's rolling members. The guides 104 may also include support or reinforcement for distribution of the rack's weight. As depicted, the guides include a bottom portion 108 and a side portion 110 extending vertically from the bottom portion 108. In an embodiment, the rolling members roll along the bottom portion 108 and are guided by side portions 110 to position the rack properly on the mat 102. Stops 112 are located at the end of each guide 104 to prevent the rolling members from rolling off the guides 104. As depicted, the guides 104 and elongated members 106 are substantially perpendicular to one another. In embodiments, the support structure, including elongated members 104 and guides 104 may include any suitable number of members arranged in any suitable fashion to enable accurate positioning of the rack while providing structural support and weight distribution for the rack while protecting the mat 102. Further, the mat 102 is a durable protective member configured to protect the floor surface beneath the mat 102 from the weight of the rack installed on the apparatus.
Removable adapters 114 are connected to blocks 116 on the guides 104 to provide guidance as the rack rollers are received on a first side 115 of the mat 102. The adapters 114 may be any suitable shape and configuration, such as the L-shape cross-section, with a bottom portion 118 and a side portion 120. The adapters 114 include an angled portion 121 to receive the rack's rolling members at a range of angles and guide them to the guides 104. The adapters 114 may also include a ramped or tapered portion 122 to provide a flush surface transition to the mat 102 and enable rack movement onto the adapters 114. The integrated installation apparatus 100 also include key features 124 and 126 in the mats 102 to enable coupling to similar key features of adjacent integrated installation apparatus 100, as discussed below with reference to FIG. 5. The key features 124, 126 may be any suitable configuration and geometry to enable alignment and coupling between adjacent integrated installation apparatus 100.
The mat 102 may be made from any suitable durable hard material, such as but not limited to a plastic and/or rubber compound. In an embodiment, the mat 102 material protects the elevated floor from the rack and is coupled to the floor by a suitable mechanism, such as adhesives or fasteners. One embodiment of the mat 102 may be formed from a polycarbonate resin thermoplastic (e.g., Lexan®). The weight distribution structure, including elongated members 106, may be formed from a suitable structurally supportive material, such as but not limited to steel alloy, carbon fiber and/or plastic. In addition, the guides 104 may also be formed from a suitable structurally supportive material, such as but not limited to the following example materials, steel alloy, carbon fiber and/or plastic. In an embodiment, the guides 104 and elongated members 106 are coupled to the mat 102 by any suitable mechanism, such as but not limited to adhesives and/or fasteners. In another embodiment, the guides 104 and/or elongated members 106 are coupled to the mat 102 by being formed or molded as part of the mat 102 when the mat 102 is created from a material, such as a thermoplastic. In other embodiments, the guides 104 and/or elongated members 106 are coupled to the mat 102 after each part is formed or made. The removable adapters 114 may be formed from a suitable structurally supportive material, such as but not limited to steel alloy, carbon fiber and/or plastic.
Referring now to FIG. 3, another embodiment of an integrated installation apparatus 300 is shown. The weight distribution structure includes elongated members 302 arranged in a cross or X-shaped pattern to distribute the rack's weight across a surface area of the mat 102.
