Module to couple to a plurality of backplanes in a chassis

A method comprising:

• inserting a module in a slot in a chassis, the module including a first communication interface to couple to a first backplane and a second communication interface to couple to a second backplane, both backplanes located within the chassis, the chassis further including two air plenums located above and below the plurality of slots, the second backplane mounted in one of the air plenums;
• coupling in communication the module to another module inserted in another slot in the chassis, the coupling in communication via the module's communication interfaces;
• and
• forwarding data between the module and the other module, the data forwarded through at least one communication interface coupled to the first backplane and/or through at least one communication interface coupled to the second backplane.

A system comprising:

• a chassis including a plurality of slots to receive modules and a plurality of backplanes to include a first and a second backplane, the chassis further including two air plenums located above and below the plurality of slots, the second backplane mounted in one of the air plenums;
• a module received in a first slot of the plurality of slots;
• and
• another module received in a second slot of the plurality of slots, the other module to include:
• a first communication interface to couple the other module to a first backplane in the chassis via an interconnect configured to couple a fabric interface associated with the first communication interface to a communication channel routed over the first backplane to the module received in the first slot;
• and
• a second communication interface to couple the other module to a second backplane in the chassis via an interconnect.
