Patent ID: 8842664

Claim:
An Advanced Telecommunications Computing Architecture (ATCA) shelf, comprising: a shelf housing having a plurality of slots, each of the slots being available to receive a payload blade; a backplane electrically coupling each of the slots with both a first integrated chassis management module (ICMM) and a second ICMM; the first ICMM comprising: a printed circuit board having a shelf management controller and a multiport switch; a hub that electrically couples the shelf management controller to each of the slots, the hub being integrated onto the same printed circuit board as the shelf management controller of the first ICMM; a first Ethernet port that electrically couples the shelf management controller of the first ICMM to a shelf management controller of the second ICMM by way of a multiport switch of the second ICMM, via the backplane; and a second Ethernet port that electrically couples the shelf management controller of the first ICMM to the shelf management controller of the second ICMM by way of the multiport switch of the first ICMM, via the backplane; the second ICMM comprising a hub that electrically couples the shelf management controller of the second ICMM to each of the slots, the hub being integrated onto the same printed circuit board as the shelf management controller of the second ICMM; and the first shelf management controller and the second shelf management controller each being configured to manage and control each payload blade disposed within the slots, including selectively controlling power that is provided to the hubs of the first and second ICMMs.
