    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 37: 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 38: Connecting Leaf Switches To Spine Switches

    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 39 • If there are modular switches in the fabric, their ACI-mode line cards must already be installed. The line cards can be of the following types: • 36-port 40-Gigabit (such as: N9K-X9736PQ) • 32-port 100-Gigabit (such as: N9K-X9732C-EX) (supported by Cisco Nexus 9504 and 9508 modular switches) • 36-port 100-Gigabit (such as: N9K-X9736C-FX) Note You cannot include NX-OS line cards in the same chassis when running in ACI mode.
