N5K-C5672UP-16G combines 16-Gbps Fibre Channel connectivity with fixed 10 Gigabit Ethernet access and 40 Gigabit Ethernet uplinks in a 1U data center switch. Forty-eight SFP+ interfaces include a unified-port section for Ethernet and native storage connections, while six QSFP+ interfaces provide upstream connectivity. Base software supplies Layer 2 switching for server-facing Ethernet links. Compared with the discontinued N5K-C5672UP, the unified-port count increases from 16 to 24. The Cisco Nexus 5672UP-16G brings server and SAN connections into the same chassis; its fixed interfaces do not require a removable uplink card. Copper access ports and endpoint PoE are not provided.
N5K-C5672UP-16G price for new stock is $2,409.75, a 93.8% saving from the Cisco list price of $38,679.00. N5K-C5672UP-16G refurb price is $971.25. N5K-C5672UP-16G is in stock and available for next-day dispatch. (terms applied)

1440 Gbps switching capacity and 1071 Mpps forwarding rate support line-rate Ethernet forwarding. N5K-C5672UP-16G provides separate management and console interfaces for out-of-band administration. For port-side intake, match N6K-C6001-FAN-B with NXA-PAC-1100W-B; port-side exhaust uses N6K-C6001-FAN-F with NXA-PAC-1100W. All cooling components within the chassis must use the same airflow direction, and changing direction requires powering down the chassis before replacement. 480W typical operating consumption is distinct from the output rating of a compatible power supply, so electrical planning should use chassis consumption rather than supply nameplate capacity. The power configuration also determines which AC, DC or high-voltage input connection the order requires.
N5K-C5672UP-16G is available new sealed with up to a 3-year extended ORM warranty or certified refurbished with up to a 1-year ORM warranty; every condition includes 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot and optics bay recognition, with firmware verified and configurations wiped to factory default. Specify the condition and included components on the PO; Cisco's original 1-year limited hardware warranty and service ended May 31, 2026. ORM accepts POs, offers Net-30 for government and RMA with advance replacement, and handles regional stock and RMA across the UK, EU, US and MEA for enterprise and volume orders.

In a large enterprise data center migrating to a leaf-spine architecture, deploying the N5K-C5672UP-16G (Nexus 5672UP 1RU, 24×10G SFP+, 24 pxUP SFP+, 6×40G QSFP+) as a high-density spine switch ensures sub-microsecond latency and non-blocking 40 Gbps uplinks. This use case delivers predictable east-west traffic performance, seamless scaling to hundreds of leaf switches, and simplified capacity expansion—resulting in up to 70% faster VM migration and 50% lower network-fabric overhead.
For hyper-converged infrastructure running mixed compute and storage traffic, the Nexus 5672UP’s unified I/O (24 10 Gbps SFP+ ports with 16 pxUP for lossless storage and six 40 Gbps QSFP+ uplinks) consolidates LAN and SAN on a single fabric. This deployment reduces rack cabling by 60%, optimizes throughput for iSCSI/NFS workloads, and simplifies QoS management—delivering 40% lower TCO and consistent sub-millisecond storage latency.
Cloud service providers leveraging VXLAN-EVPN for tenant isolation deploy the Nexus 5672UP as Top-Of-Rack switches to handle overlay networks at 40 Gbps. Integrated hardware-based VXLAN forwarding, programmable QoS, and 16 pxUP support secure multi-tenant segmentation with up to 16 million routes. This solution accelerates service onboarding by 3×, delivers predictable tenant SLAs, and ensures 99.999% network availability across hundreds of racks.
When replacing discontinued N5K-C5548UP, N5K-C5548UP-FA or N6K-C6001-64P hardware, the replacement order must preserve the installed connection requirements rather than only the chassis identity. The first two models ended sale on May 5, 2019; the third on April 30, 2017. Confirm the interface assignments and installed feature entitlements before the PO.
When maintaining regional spare holdings, specify the required condition and fulfillment region alongside the quantity. ORM offers new sealed and certified refurbished conditions, regional stock and RMA across the UK, EU, US and MEA, and RMA with advance replacement. Record the regional stock and replacement requirements before submitting the PO.
25G server links or 100G uplinks
N5K-C5672UP-16G provides 10G server interfaces and 40G uplinks. The current N9K-C93180YC-FX3 supports 48 interfaces at 1/10/25G and six at 40/100G.
Active Cisco service coverage
Cisco service for N5K-C5672UP-16G ended May 31, 2026. N9K-C93180YC-FX3 is the current successor at the end of the replacement chain.
Powered copper access endpoints
N5K-C5672UP-16G has no RJ-45 access ports or PoE output. Its server-facing connections use SFP+ interfaces, so direct copper access and inline endpoint power require different hardware.

N5K-C5672UP-16G identifies a Nexus 5672UP-16G chassis with 24 Ethernet-only SFP+ ports, 24 unified SFP+ ports and six 40G QSFP+ ports. N5K names the Nexus 5000 family; C5672UP identifies the model, UP denotes unified ports, and 16G identifies 16-Gbps Fibre Channel support rather than Ethernet uplink speed.
Nexus 5600 switches use the NX-OS CLI through console, SSHv2 or Telnet, with in-band or dedicated management-port access. SNMPv1/v2/v3 and XML NETCONF support external management. Cisco Prime DCNM, Cisco Fabric Manager and CiscoWorks LMS provide management applications; the dedicated management interface supports Gigabit Ethernet.
N5K-C5672UP-16G is discontinued: Cisco ended sales on May 5, 2021, and support on May 31, 2026. Cisco service has ended. The direct replacement, N9K-C93180YC-FX, is also discontinued; its replacement is the current N9K-C93180YC-FX3. Remaining hardware stock is legacy inventory, not a supported current Cisco switch.
N5K-C5672UP-16G is available new sealed with up to a 3-year extended ORM warranty, or certified refurbished with up to a 1-year ORM warranty. Returns are accepted for 30 days in either condition; terms apply. Cisco's original 1-year limited hardware warranty and Cisco service ended May 31, 2026.
N5K-C5672UP-16G needs additional routing and storage licenses beyond base Layer 2 software, originally bought individually or through Cisco ONE Software. Layer 3 Base Services N56-BAS1K9 permits 256 dynamic routes across protocols; Layer 3 Enterprise Services N56-LAN1K9 requires the base package. Storage Protocols Services is a separate package.
N5K-C5672UP-16G replaces the discontinued N5K-C5548UP, N5K-C5548UP-FA and N6K-C6001-64P. The two Nexus 5548UP order variants ended sale on May 5, 2019; N6K-C6001-64P ended sale on April 30, 2017. Match the installed interfaces, storage connections and software entitlements before placing a replacement order.
N5K-C5672UP-16G provides 24 unified ports, whereas N5K-C5672UP provides 16 unified ports. Both models are discontinued. The 24-unified-port model suits existing configurations requiring more native storage-facing interfaces; the 16-unified-port model matches installations originally specified around the smaller unified-port section. Match the original connection schedule when ordering legacy spares.
N5K-C56128P provides four power-supply bays, while N5K-C5672UP-16G provides two power-supply bays. Both switches are discontinued, so this comparison concerns existing equipment requirements rather than a current-product recommendation. N5K-C56128P matches four-bay power configurations; N5K-C5672UP-16G matches two-bay installations. Confirm the original chassis requirement on the spare-hardware order.
N9K-C93180YC-FX3 supports 25G server-facing connections, while N5K-C5672UP-16G supports 10G server-facing connections. N9K-C93180YC-FX3 is the current successor following the discontinued N9K-C93180YC-FX. Retaining an existing 10G installation can require the legacy model; a refresh requiring native 25G server links calls for the current successor.
Cisco Nexus 5672UP-16G has a maximum power consumption of 550W and a typical operating consumption of 480W. These are chassis-consumption figures, not the 1100W output rating of a compatible NXA-PAC-1100W supply. Rack-power allocation should use the maximum rather than only the typical operating load.
