N5K-C5624Q provides twelve fixed 40G QSFP+ ports in a managed data-center switch with an empty expansion bay. The Nexus 5624Q occupies one rack unit for top-of-rack or middle-of-row server connections. Layer 2 switching is available without assuming additional routing entitlements. The Nexus 5600 family supports Ethernet server access and aggregation rather than powered RJ-45 endpoint connections. Unlike the discontinued N5624-B-24Q bundle, the base chassis does not include N5600-M12Q. Two installed power supplies provide 1+1 redundancy, while three fans operate with 2+1 redundancy. Server-facing and upstream connections use the same QSFP+ interface class, so link allocation depends on the network design rather than dedicated copper uplink ports.
N5K-C5624Q price for new stock is $31,972.21. N5K-C5624Q refurb price is $328.87. N5K-C5624Q is in stock and available for next-day dispatch. (terms applied)

1920 Gbps maximum switching capacity represents the fully expanded chassis, rather than an included expansion module. 1428 Mpps maximum forwarding at 64-byte packet size provides a reference for small-frame traffic sizing. The shared 256000-entry MAC and ARP resource requires address-table planning across both uses instead of treating each as an independent allowance. N5K-C5624Q supports a 25 MB packet buffer shared by each group of three 40G ports, making congestion planning specific to those interface groups. PVRST+, MSTP and LACP support Layer 2 topology control and link aggregation, while vPC supports port-channel connections across paired switches. Jumbo frames reach 9216 bytes for networks carrying larger frames. NX-OS configuration rollback and role-based access control support change handling and administrative separation. 1100W maximum power consumption establishes the upper electrical load for rack power planning; the 750W typical operating figure is a different sizing reference, not the maximum.
N5K-C5624Q is available from ORM Systems new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed port links, optics bay recognition, module bay recognition, PSU status and fan status, with firmware verified and configuration wiped to factory default. Specify the condition and confirm the complete hardware and software contents before placing the order. ORM provides up to a 3-year extended warranty for new units or up to 1 year for certified refurbished units, plus 30-day returns on every condition, terms apply; Cisco hardware warranty and service ended September 30, 2025. POs are accepted, government buyers can use Net-30, and enterprise or volume orders have stock and RMA handling across the UK, EU, US and MEA, including RMA with advance replacement.

When a rack refresh retains 10G server connections, breakout connectivity allows a fully expanded chassis to support 96 10G interfaces. QSFP-4SFP10G-CU3M provides a supported 3 m breakout option. Establish which connections remain native-speed links, then specify server connector compatibility, expansion requirements and cable quantities before the PO.
When equipment rows use different cold-aisle orientations, airflow must be selected per installation rather than standardized by chassis PID alone. NXA-PAC-1100W-B provides port-side intake, paired with N6K-C6001-FAN-B. Match every supply and fan to the same airflow direction and specify the complete airflow set before ordering.
When a staging environment needs packet-level troubleshooting before equipment enters service, SPAN and ERSPAN support 31 line-rate sessions. The embedded packet analyzer adds local inspection without requiring a different chassis. Identify the observation points, traffic destinations and monitoring configuration in the staging plan before issuing the PO.
Native 100G network connections
N5K-C5624Q cannot provide native 100G interfaces. N9K-C9336C-FX2 is the current migration replacement, offering 36 ports supporting 40G or 100G rather than a like-for-like port configuration.
Copper access ports with PoE
N5K-C5624Q uses QSFP+ data interfaces rather than powered RJ-45 access ports. Direct copper endpoint connections with PoE are outside this chassis configuration; expansion does not add PoE access.

N5K-C5624Q identifies the Nexus 5624Q base chassis with two power supplies, three fans and no generic expansion module. The complete PID specifies the chassis configuration, not a fully populated 24-port bundle. Twelve fixed 40G QSFP+ ports are installed, and the expansion module is a separate component.
N5K-C5624Q is managed through the NX-OS CLI using console access, SSHv2 or Telnet, with in-band or dedicated Ethernet management. Monitoring and automation include SNMPv1, SNMPv2, SNMPv3 and XML NETCONF. Cisco Prime DCNM provides a GUI; Cisco Fabric Manager and CiscoWorks LMS are also supported management applications.
N5K-C5624Q is discontinued: end of sale was September 9, 2020, and Cisco support ended September 30, 2025. Cisco hardware service and vulnerability support have ended. N9K-C9336C-FX2 is the current migration replacement, but its port configuration requires a migration review rather than a like-for-like substitution.
N5K-C5624Q uses perpetual feature licensing without a subscription minimum; individual feature licenses and historical Cisco ONE bundles are separate packaging paths. N56-BAS1K9 covers Layer 3 Base features, while N56-LAN1K9 covers Layer 3 Enterprise features. FabricPath and storage require their own entitlements, which must be verified separately from chassis ownership.
N5K-C5624Q supports OSPF and BGP with the appropriate software entitlements, not simply through chassis ownership. N56-BAS1K9 enables OSPFv2 with a 256-dynamically-learned-route limit and EIGRP Stub. N56-LAN1K9 adds full EIGRP, OSPF and BGP. Confirm installed licenses before specifying the chassis for routed operation.
N5K-C5624Q includes 12 fixed 40G QSFP+ ports and one empty expansion bay. Adding N5600-M12Q supplies another 12 QSFP+ interfaces, bringing the chassis to 24 native 40G ports. The base PID does not include N5600-M12Q, so distinguish installed port count from maximum chassis capacity when preparing the order.
The Nexus 5624Q supports QSFP-40G-SR4 for multimode fiber and QSFP-40G-LR4 for single-mode fiber with duplex LC connectivity. QSFP-H40G-CU3M is a supported 3 m direct-attach copper option. Specify the medium, connector, distance and opposite-end interface before selecting the optical or direct-attach component.
N5K-C5624Q supports NXA-PAC-1100W for port-side exhaust AC operation and NXA-PAC-1100W-B for port-side intake AC operation. N55-PDC-1100W provides a DC option, while NXA-PHV-1100W and NXA-PHV-1100W-B support high-voltage inputs. The selected supplies and fans must share one airflow direction; confirm the installed supply PIDs on the order.
Yes, the Nexus 5624Q is a rack-mounted 1U switch rather than a desktop model. N5672-ACC-KIT supplies its rack-mount guides, brackets and sliders. Account for the 762 mm chassis depth, connection clearance and the selected airflow direction when checking cabinet fit and the completeness of the offered mounting hardware.
N5K-C5624Q ships without N5600-M12Q, while the discontinued N5624-B-24Q bundle includes N5600-M12Q and 24 native 40G ports. Both configurations are discontinued. The base chassis matches purchases involving separately specified expansion; the historical bundle identifies a populated configuration, not a current replacement for an obsolete chassis.
N5K-C5624Q includes two power supplies with 1+1 redundancy, while the discontinued N5K-C5648Q includes four with 2+2 redundancy. Both models are discontinued. Existing two-supply installations correspond to N5K-C5624Q; four-supply inventories correspond to N5K-C5648Q, so power-system matching matters when identifying legacy equipment or spare chassis.
N5K-C5624Q provides native 40G interfaces, while N9K-C9336C-FX2 provides 36 ports supporting 40G or 100G. N5K-C5624Q is discontinued and out of Cisco support; N9K-C9336C-FX2 is its current migration replacement. Existing 40G hardware matching points to the legacy chassis, while native 100G requirements point to the replacement.
ORM Systems offers N5K-C5624Q new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units. Every condition has 30-day returns; terms apply. Cisco's original 1-year limited hardware warranty and Cisco service ended September 30, 2025.
