If Expansion Shelves are included in your system, the 10GbE switch ports on each MCH card (AMC671 MicroTCA Carrier Hub (MCH) card), must be connected to enable inter-shelf traffic links, as shown in the following figure. The cables are provided with the DSC 8000 (refer to Unpacking the DSC 8000).

Connection between these switches is accomplished using the 10 Gbit Ethernet connectors on the Ethernet Switch faceplate (see AMC671 Faceplate).       

Two 1m (3 ft.) cables (Ribbon part number 160Q078010) are provided with each Expansion shelf. This cable has an embedded SFP connector at each end providing 10G operation over coax between the shelves.  These cables connect between FP1 of the Expansion shelf and FP2 of the shelf immediately above the Expansion shelf. The shelf above the Expansion shelf may be another Expansion shelf or it may be the Control shelf. FP1 of the left-most MCH in the Expansion shelf connects to FP2 on the left-most MCH of the shelf above. FP1 of the right-most MCH in the Expansion shelf connects to FP2 on the right-most MCH of the shelf above.      

Two 3m (9 ft) cables (Ribbon part number 11-160Q075610) are provided to connect the Control shelf MCHs with the bottom-most Expansion shelf MCHs.  This cable has an embedded SFP connector at each end providing 10G operation over coax between the shelves. These cables connect between FP2 of the bottom-most Expansion shelf and FP1 of the Control shelf. FP2 of the left-most MCH in the bottom-most Expansion shelf connects to FP1 on the left-most MCH of the Control shelf. FP2 of the right-most MCH in the bottom-most Expansion shelf connects to FP1 on the right-most MCH of the Control shelf.  

  1. Remove the tabs that are inside the Ethernet Switch connectors.
  2. Connect the Ethernet switches as shown in the following diagram, which shows the ethernet cable connections between the shelves.
