Modular platform system and apparatus

A system comprising:

• a rack;
• and
• a plurality of modular platforms mounted in the rack, at least one of the modular platforms including
• a modular platform shelf having a first end, the modular platform shelf configured to removably receive one or more modular platform boards, and
• a first dual plenum having a first plenum portion and a second plenum portion, the first plenum portion coupled to the first end of the modular platform shelf, and the second plenum portion adapted to interface with a second end of an another modular platform shelf of an adjacent modular platform;
• a power entry module adapted to electrically interconnect to the one or more modular platform boards;
• and a rear transition module configured to interconnect to a rear transition module interface, the rear transition module having a standoff distance sufficient to allow the power entry module to be positioned substantially between the rear transition module and a rear portion of the corresponding modular platform board.

A method of arranging modular platforms, comprising:

• providing at least a first and a second modular platform, each including a dual plenum, a modular platform shelf, a power entry module, and a rear transition module, the dual plenum of the first modular platform having a first plenum portion and a second plenum portion, the first plenum portion being coupled to and in fluid communication with a first end of the modular platform shelf of the first modular platform;
• positioning the power entry module substantially between the rear transition module and a rear portion of the corresponding modular platform board;
• providing a stand-alone plenum;
• stacking the first and second modular platforms in vertical array, wherein a second end of the modular platform shelf of the second modular platform is in fluid communication with the second plenum portion of the dual plenum of the first modular platform;
• and
• stacking the first modular platform in a vertical array with the stand-alone plenum so that the stand-alone plenum is in fluid communication with a second end of the modular platform shelf of the first modular platform.

A method of arranging modular platforms, comprising:

• providing a first, second, third, and fourth modular platform, each including a dual plenum, a modular platform shelf having a first end and a second end, a power entry module, and a rear transition module, each dual plenum of each modular platform having a first plenum portion and a second plenum portion, the first plenum portion of each dual plenum each modular platform being coupled to a first end of a corresponding to modular platform shelf;
• positioning the power entry module substantially between the rear transition module and a rear portion of the corresponding modular platform board;
• providing a stand-alone plenum;
• and
• stacking the first, second, third, and fourth modular platforms and the stand-alone plenum in a system rack, wherein each of at least three modular platform shelves are in fluid communication with a separate one of the first plenum portions and one of the second plenum portions, and at least one of the modular platforms is in fluid communication with a different one of the first plenum portions and the stand-alone plenum.
