    Cisco equipment. In situations where long parallel cable runs cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield any potential noise sources by housing them in a grounded metallic conduit.

  • Page 35: Connecting Leaf Switches To Apics

    Connecting Leaf Switches to APICs You must downlink one or two (recommended for redundancy) Cisco Nexus 9300 platform ACI-mode leaf switches to each Application Policy Infrastructure Controller (APIC) in your ACI fabric. The type of virtual interface card (VIC) installed on the APIC determines the types of interface cables that you can use to connect the leaf switches to the APICs.
  • Page 36 Connect the other end of the interface cable to a downlink port on a leaf switch. • For a Cisco 10GBASE-LR or -SR transceiver and cable, insert the transceiver into a downlink optical port on a leaf switch before connecting the cable to the transceiver.

  • Page 37: Connecting Leaf Switches To Spine Switches

    You cannot include NX-OS line cards in the same chassis when running in ACI mode. Note Multiple uplinks from a leaf switch to a spine switch is supported.

    Register the new second generation switch with the Cisco APIC. Register the new node with the same node name and node ID. This switch becomes part of the fabric. The Cisco APIC pushes the policies to the new switch and keeps down the vPC legs because there is a mismatch of the generation of switches.
