Cisco Nexus 9300 48x 1G RJ-45 + 4x 10G + 2x 40/100G | Data Center Switch — CON-NCDT-ASR105GK

Handle mixed-speed connectivity without fragmenting the fabric. This Cisco Nexus 9300 configuration combines 48 1G RJ-45 ports with 4 10G ports and 2 40/100G QSFP28 ports, giving teams a compact way to support legacy devices, management networks, and higher-speed aggregation in one switch. That port mix is useful when not every endpoint is ready for 10G or 25G, but the uplink layer still needs serious bandwidth. The 1G RJ-45 ports can serve access or management roles, while the 10G and 40/100G interfaces provide a clear path for uplink consolidation and future fabric growth. It is a better fit than a single-speed access switch when you need to bridge generations of infrastructure without overcomplicating the rack. For enterprise data centers, this kind of configuration helps preserve design flexibility. You can keep lower-speed endpoints connected, reserve faster ports for aggregation, and avoid forcing a full refresh before the network is ready. The result is a switch that supports practical migration planning and disciplined capacity use. Ideal For Access switch for mixed-generation server and appliance connectivity Aggregation layer for data center racks with 1G and 10G endpoints Migration platform for phased upgrades to 40G and 100G uplinks Edge switch for enterprise data centers with copper-based access requirements Why This Product 1 More flexible for mixed-speed environments than fixed-speed access switches 2 Provides faster uplinks than 1G-only or 10G-only edge models 3 Better migration fit than switches without 40/100G uplink options 4 Balances copper access and high-speed fabric connectivity in one chassis
