N5K-C5672UP provides managed data center switching through 48 fixed 1/10G SFP+ ports and six fixed 40G QSFP+ uplinks. Sixteen SFP+ interfaces are unified ports supporting native Fibre Channel connectivity. The Nexus 5672UP occupies one rack unit and runs a Layer 2 base image, with additional feature licenses enabling routing and storage functions. The discontinued N5K-C5672UP-16G differs by providing 24 unified ports supporting 16G Fibre Channel, rather than 16 unified ports supporting 8G Fibre Channel. Both belong to the Nexus 5600 family of server-access switches.
N5K-C5672UP price for new stock is $5,197.50. N5K-C5672UP refurb price is $273.00. N5K-C5672UP is in stock and available for next-day dispatch. (terms applied)

1440 Gbps switching capacity and 1071 Mpps forwarding at 64-byte packets support wire-speed packet handling. N5K-C5672UP uses cut-through forwarding, with 25 MB buffering per 12 SFP+ interfaces for queued traffic. PVRST+, MSTP, and LACP are available in the base image; dynamic routing is not included without additional feature licenses.
N5K-C5672UP is offered new sealed or certified refurbished, with ORM warranties of up to a 3-year extended term for new units and up to 1 year for refurbished units; returns are 30 days on every condition, with terms applying. Refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, optics bay recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. Specify condition and required accessories on the PO. Enterprise and volume orders accept POs, government Net-30, and RMA with advance replacement across UK, EU, US, and MEA stock and RMA regions.

In a global financial services firm hosting 2,000+ VMware VMs, the N5K-C5672UP Nexus 5672UP chassis is deployed as a top-of-rack leaf switch. Its 32×10 Gbps SFP+ and 6×40 Gbps QSFP+ ports deliver sub-10 µs latency and 1.28 Tbps of switching capacity to accelerate east-west traffic. The result is 40% faster VM migrations, linear scaling to thousands of servers, and simplified VXLAN overlays for real-time analytics and disaster recovery.
At a university research lab running GPU-intensive AI training jobs, the Nexus 5672UP chassis aggregates 16 compute nodes over 10 Gbps SFP+ and uplinks dual 40 Gbps QSFP+ to the core fabric. Its unified ports support RDMA over Converged Ethernet (RoCE) for microsecond-class inter-GPU communication. This architecture yields 50% higher throughput on TensorFlow workloads, reduces network-induced bottlenecks, and accelerates time-to-insight for deep learning models.
A healthcare provider integrates on-premises VMware and Azure Stack services with an FCoE-enabled Nexus 5672UP chassis. Leveraging 16 unified ports, it converges 10 Gbps LAN and 10 Gbps SAN traffic onto a single 1RU footprint, while dual 40 Gbps uplinks connect to public and private clouds. The deployment cuts cable complexity by 30%, reduces CapEx by 20%, and streamlines policy-driven segmentation for patient data compliance and rapid disaster recovery.
An existing Ethernet and Fibre Channel layout needs a port-map review before a replacement chassis order. Native Fibre Channel assignments must occupy a contiguous range within ports 33–48 and finish at port 48. Specify the intended port personalities and required storage entitlements before the PO.
A spare for an existing row needs the same cooling direction as the installed equipment. N6K-C6001-FAN-B uses port-side intake, while N6K-C6001-FAN-F uses port-side exhaust. Fan modules and power supplies must share one airflow direction. Specify airflow and matching power-supply components before ordering.
16G native Fibre Channel connectivity
N5K-C5672UP supports native Fibre Channel at 2G, 4G, or 8G on its unified ports; 16G operation is unavailable on this model.
Active Cisco hardware support
N5K-C5672UP hardware support ended August 31, 2026. A purchase cannot include continuing Cisco hardware service for this discontinued chassis.

N5K-C5672UP identifies the Nexus 5672UP chassis, with UP referring to unified ports. Its configuration combines 32 Ethernet SFP+ ports, 16 unified SFP+ ports, and six QSFP+ ports. The PID has no appended license-tier suffix; separately installed feature licenses determine additional software functions.
N5K-C5672UP supports CLI management through console access, SSHv2, or Telnet, plus SNMPv1/v2/v3 and XML NETCONF. Central management options include Cisco Fabric Manager, Cisco Prime DCNM, and CiscoWorks LMS. Both in-band management and the dedicated management interface are supported for administration.
Yes, N5K-C5672UP is discontinued: end of sale was May 5, 2021, and hardware support ended August 31, 2026. NX-OS 7.3 support ended May 31, 2026. No direct replacement is assigned to this exact chassis PID, so an order is for unsupported legacy hardware.
ORM Systems offers N5K-C5672UP new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Returns are 30 days for every condition; terms apply. Cisco's original 1-year limited hardware warranty has ended, and hardware support ended August 31, 2026.
Nexus 5600 switches use base Layer 2 software with optional individual feature licenses or Cisco ONE suites. N56-BAS1K9 enables Layer 3 Base Services; N56-LAN1K9 adds Enterprise Services and requires N56-BAS1K9. FabricPath uses N5672-EL2-SSK9, while storage functions have separate entitlements. Confirm the supplied unit's licenses before ordering.
N5K-C5672UP replaces N5K-C5548P and N5K-C5548P-FA, whose end-of-sale date was September 26, 2015, and N6K-C6001-64P=, whose end-of-sale date was April 30, 2017. These are historical migration relationships; N5K-C5672UP is itself discontinued and should not be treated as a current supported upgrade.
The Nexus 5672UP assigns native Fibre Channel within ports 33–48, using a contiguous range that must end at port 48. Ethernet and Fibre Channel ports of the same type must remain contiguous. Review the intended port map and storage entitlements before configuring mixed Ethernet and storage connections.
N5K-C5672UP has 400W typical operating consumption and 450W maximum consumption. Compatible NXA-PAC-1100W and N55-PAC-1100W supplies have 1100W rated output, which is not the chassis draw. Size rack power using consumption figures, and confirm the installed supply type before specifying electrical connections.
No, N5K-C5672UP has a Layer 2 base image; routing requires N56-BAS1K9. That license enables unlimited static routes plus RIPv2, OSPFv2, OSPFv3, and EIGRP Stub, with a shared maximum of 256 dynamic routes across protocols. Additional Enterprise Services require N56-LAN1K9 alongside N56-BAS1K9.
N5K-C5672UP provides 16 unified ports supporting 8G Fibre Channel, whereas N5K-C5672UP-16G provides 24 unified ports supporting 16G Fibre Channel. Both models are discontinued. For legacy replacement orders, N5K-C5672UP matches the 16-port unified configuration; N5K-C5672UP-16G matches installations requiring the 24-port storage configuration.
N5K-C5672UP has fixed interfaces, whereas N5K-C56128P has two expansion slots accepting N56-M24UP2Q modules. Those modules are exclusive to N5K-C56128P and cannot expand N5K-C5672UP. Both switches are discontinued; legacy orders should match a fixed-interface installation or an existing expansion-module configuration respectively.
No, N5K-C5672UP-RF identifies Cisco remanufactured hardware, while an ORM certified refurbished N5K-C5672UP is inspected and bench-tested through ORM's refurbishment process. ORM managed units also have firmware verified and configurations wiped to factory default. Specify the refurbishment condition explicitly rather than treating the two descriptions as interchangeable.
