Page 7: Overview
Overview, on page 1 Overview The Cisco Nexus 9348GC-FX3 switch (N9K-C9348GC-FX3) is a 1-rack unit (RU) switch that supports 696 Gbps of bandwidth and over 517 Mpps. The 48 1GBASE-T downlink ports on the 9348GC-FX3 can be configured to work as 100-Mbps or 1-Gbps ports. The 4 ports of SFP28 can be configured as 1/10/25-Gbps and the 2 ports of QSFP28 can be configured as 40- and 100-Gbps ports, or a combination of 10-, 25-, 40, and 100-Gbps connectivity, offering flexible migration options for spine-leaf-APIC deployment in data centers.

Page 33: Connecting The Switch To The Aci Fabric
As shown in the following figure, each APIC is connected to one or two leaf switches and each leaf switch should be connected to every spine switch in the same fabric. Cisco Nexus 9348GC-FX3 ACI-Mode Switch Hardware Installation Guide...
Page 34: Preparing To Connect To Other Devices
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
Connecting the Switch to the ACI Fabric Connecting Leaf Switches to Spine Switches • For Cisco SFP+ Active Optical Cables, insert the transceiver on the cable into a downlink optical port on a leaf switch. • For a 10GBASE-T copper cable, insert the RJ-45 connector on the cable into a downlink BASE-T port on a leaf switch.
