The first and second bottom side-to-side beams each comprise an opening configured to allow a removable transport caster to pass through the opening, a first set of keyholes configured to receive and retain a set of mounting buttons of a first removable transport caster, and a second set of keyholes configured to receive and retain a set of mounting buttons of a second removable transport caster. ## Claims ### Claim 1 A data center cabinet, comprising: a base frame including a pair of front vertical posts, a first bottom side-to-side beam and a first top side-to-side beam positioned between and connected to the pair of front vertical posts, a pair of back vertical posts, a second bottom side-to-side beam and a second top side-to-side beam positioned between and connected to the pair of back vertical posts, a first pair of front-to-back beams positioned between and connected to one of the pair of front vertical posts and one of the pair of back vertical posts, and a second pair of front-to-back beams positioned between and connected to the other of the pair of front vertical posts and the other of the pair of back vertical posts; wherein the first and second bottom side-to-side beams each comprise an opening configured to allow a removable transport caster to pass through the opening, a first set of keyholes configured to receive and retain a set of mounting buttons of a first removable transport caster, and a second set of keyholes configured to receive and retain a set of mounting buttons of a second removable transport caster. ### Claim 2 (depends on 1) The data center cabinet of claim 1, wherein the first and second bottom side-to-side beams each comprise a first lock hole configured to receive a retractable spring pin of the first removable transport caster and a second lock hole configured to receive a retractable spring pin of the second removable transport caster. ### Claim 3 (depends on 1) The data center cabinet of claim 1, further comprising a first pair of adjustable leveling legs attached to the first bottom side-to-side beam and a second pair of adjustable leveling legs attached to the second bottom side-to-side beam. ### Claim 4 (depends on 1) The data center cabinet of claim 1, wherein the openings are centrally located along the side-to-side beams. ### Claim 5 (depends on 1) The data center cabinet of claim 1, comprising the first and second removable transport casters, the first and second removable transport casters each comprising: a swivel caster; and a mounting plate secured to the swivel caster, the mounting plate comprising a plurality of mounting buttons extending from a top surface of the mounting plate and configured to be received and retained in a plurality of keyholes in the data center cabinet. ### Claim 6 (depends on 5) The data center cabinet of claim 5, wherein the mounting plate comprises a retractable spring pin extending from the top surface of the mounting plate and configured to be received in a lock hole in the data center cabinet. ### Claim 7 (depends on 5) The data center cabinet of claim 5, wherein the mounting plate is secured to the swivel caster by a plurality of threaded members extending from a bottom surface of the mounting plate and through corresponding holes in the swivel caster and a plurality of lock nuts threaded onto corresponding threaded members. ### Claim 8 (depends on 5) The data center cabinet of claim 5, wherein the mounting button has neck portion and head portion, the head portion having a larger diameter than the neck portion. ### Claim 9 (depends on 8) The data center cabinet of claim 8, wherein the neck portion is configured to fit through a first portion of a corresponding keyhole and the head portion is configured to fit through a second portion of the corresponding keyhole and not the first portion. ### Claim 10 A transport caster for use with a data center cabinet, the transport caster comprising: a swivel caster; and a mounting plate secured to the swivel caster, the mounting plate comprising a plurality of mounting buttons extending from a top surface of the mounting plate and configured to be received and retained in a plurality of keyholes in the data center cabinet. ### Claim 11 (depends on 10) The transport caster of claim 10, wherein the mounting plate comprises a retractable spring pin extending from the top surface of the mounting plate and configured to be received in a lock hole in the data center cabinet. ### Claim 12 (depends on 10) The transport caster of claim 10, wherein the mounting plate is secured to the swivel caster by a plurality of threaded members extending from a bottom surface of the mounting plate and through corresponding holes in the swivel caster and a plurality of lock nuts threaded onto corresponding threaded members. ### Claim 13 (depends on 10) The transport caster of claim 10, wherein the mounting button has neck portion and head portion, the head portion having a larger diameter than the neck portion. ### Claim 14 A method of installing a transport caster on a data center cabinet, the method comprising the steps of: raising the data center cabinet; inserting the transport caster in a side-to-side beam of the data center cabinet; inserting a mounting button of the transport caster through a keyhole in the side-to-side beam; sliding the transport caster along the side-to-side beam such that the mounting button is retained in the keyhole; and lowering the data center cabinet to rest on the transport caster. ### Claim 15 (depends on 14) The method of claim 14, wherein the transport caster is slid along the side-to-side beam until a retractable spring pin of the transport caster engages a lock hole in the side-to-side beam. ### Claim 16 (depends on 14) The method of claim 14, wherein the data center cabinet is raised and lowered by adjusting a plurality of adjustable leveling legs attached to the side-to-side beam. ### Claim 17 (depends on 16) The method of claim 16, wherein the adjustable leveling legs comprise threaded shafts that are threaded into holes in the side-to-side beam. ### Claim 18 (depends on 14) The method of claim 14, wherein the transport caster is inserted through an opening in the side-to-side beam; wherein the opening is centrally located along the side-to-side beam and the transport caster is slid towards a corner of the data center cabinet. ### Claim 19 (depends on 14) The method of claim 14, wherein the transport caster is inserted through an opening in the side-to-side beam such that the transport caster is positioned below a top wall of the side-to-side beam and is moveable longitudinally along the side-to-side beam. ### Claim 20 (depends on 14) The method of claim 14, wherein the mounting button has a neck portion configured to fit through a first portion of the keyhole and a head portion, larger than the neck portion, configured to fit through a second portion of the keyhole and not the first portion.
