N2K-C2348UPQ-10GE provides parent-managed Layer 2 server access through 48 fixed 1/10GbE SFP+ host interfaces and six fixed 40GbE QSFP+ fabric interfaces. The 1U rack chassis extends a compatible upstream Cisco Nexus switch into the server rack rather than operating as an independent access switch. Cisco Nexus 2348UPQ supports Ethernet and unified-fabric connections for rack servers, blade-server pass-through connections, and converged network adapters. The Nexus 2300 family offers port-side intake and port-side exhaust configurations for different hot-aisle and cold-aisle arrangements. The discontinued N2K-C2332TQ has 32 host interfaces, making host density a separate selection consideration. Parent-based server vPC topologies are supported, while the available attachment modes depend on the upstream switch family.
N2K-C2348UPQ-10GE price for new stock is $643.64. N2K-C2348UPQ-10GE refurb price is $103.95. N2K-C2348UPQ-10GE is in stock and available for next-day dispatch. (terms applied)

1440 Gbps hardware switching capacity and 2160 Mpps forwarding performance describe the internal forwarding hardware; fabric connectivity provides 480 Gbps full duplex, with 240 Gbps available in each direction. A 32 MB shared packet buffer accommodates traffic bursts, while eight hardware queues per port separate traffic classes for scheduling. Local multicast replication supports 8000 entries, and jumbo frames reach 9216 bytes for workloads using larger Ethernet frames. N2K-C2348UPQ-10GE sends all traffic to its parent switch, including communication between hosts attached to the same chassis, so independent local switching and routing are absent. Management runs through the parent CLI, Cisco Data Center Network Manager, SNMP, and XML NETCONF interfaces. Software compatibility checks and image updates also come from the parent. A 200W maximum input draw establishes the chassis power allowance without treating a power supply's output rating as operating consumption.
ORM Systems offers N2K-C2348UPQ-10GE new sealed and certified refurbished; refurbished units are inspected and bench-tested, with rated-speed port links, optics bay recognition, PSU status, fan status, clean boot, and firmware verification checked. New units carry up to a 3-year extended ORM warranty, certified refurbished units carry up to 1 year, and every condition includes 30-day returns; terms apply. Cisco's separate 1-year limited hardware warranty cannot extend beyond August 31, 2027. Put the required condition and quantity on the purchase order; enterprise and volume requirements can include PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock and RMA arrangements across the UK, EU, US, and MEA.

Refreshing an existing unified-fabric rack requires checking the upstream environment before retaining native Fibre Channel connections. Unified-port operation requires a Nexus 5600 parent with NX-OS 7.3(0)N1(1) or later, and 16 Gbps Fibre Channel is limited to 24 host ports. Specify the parent release and host-interface allocation before the purchase order.
Building a rack-spares pool requires matching the installation hardware as well as the chassis. N2300-ACC-KIT= includes the rack-mount kit, grounding-lug kit, and ESD strap; front and rear locator beacons identify the intended unit during service. Include the required installation kit and chassis identification requirements on the purchase order.
Independent switching without a parent
N2K-C2348UPQ-10GE performs no local switching; even traffic between attached hosts traverses its parent. Deployments requiring autonomous forwarding need a standalone switching design instead.
25G server-facing Ethernet connections
N2K-C2348UPQ-10GE host interfaces stop at 10GbE. The current replacement, N9K-C93180YC-FX3, provides 48 interfaces supporting 1/10/25GbE; optical media and attachment architecture require a migration review.
Continuing vulnerability and security maintenance
N2K-C2348UPQ-10GE reached the end of vulnerability and security support on August 23, 2025. N9K-C93180YC-FX3 is the current replacement to evaluate for migration.

N2K-C2348UPQ-10GE identifies a Cisco Nexus 2300 fabric extender with 48 1/10GbE host interfaces and six 40GbE fabric interfaces. N2K identifies the Nexus fabric-extender family, C2348UPQ identifies the unified-port model, and 10GE denotes its 10 Gigabit Ethernet host-interface class. The ending is not a software-license tier.
The Cisco Nexus 2300 is managed through its parent Cisco Nexus switch using CLI, Cisco Data Center Network Manager, SNMP, and XML NETCONF interfaces. Management travels over the fabric links. The parent discovers the extender, checks software compatibility, and updates its image when necessary rather than treating it as an independently configured switch.
N2K-C2348UPQ-10GE is discontinued, with end of sale on August 24, 2022, and last support on August 31, 2027, for eligible coverage. Vulnerability and security support ended August 23, 2025. N9K-C93180YC-FX3 is the current replacement, so hardware-support availability must not be confused with continuing security maintenance.
ORM Systems offers N2K-C2348UPQ-10GE new sealed or certified refurbished, with up to a 3-year extended ORM warranty for new units and up to 1 year for refurbished units. Both conditions include 30-day returns; terms apply. Cisco's separate 1-year limited hardware warranty is subject to eligibility and cannot extend past August 31, 2027.
N2K-C2348UPQ-10GE requires no separate fabric-extender license and has no extender-specific minimum subscription term. Its functions operate under the parent switch's software environment rather than an independent extender license tier. Parent-switch feature entitlements remain separate, so purchasing the extender does not establish permission to use licensed upstream functions.
N2K-C2348UPQ-10GE belongs to the replacement configuration for N2K-C2232PP, N2K-C2232PP-10GE, N2K-C2248PQ, and N2K-C2248PQ-10GE. The first pair reached end of sale September 9, 2020; the second pair reached end of sale November 2, 2016. Those older models are discontinued, and the replacement chain now continues to N9K-C93180YC-FX3.
N2K-C2348UPQ-10GE includes power and cooling hardware, while N2K-C2348UPQ-10GE= is the spare chassis without power supplies or fans. Both retain the same host and fabric interface configuration, and both are discontinued. The standard configuration addresses complete-unit replacement; the spare configuration assumes compatible power and cooling hardware is already available.
N2K-C2348UPQ-10GE has 48 host interfaces, while N2K-C2332TQ has 32, making host density the principal difference in this comparison. Both are discontinued members of the Nexus 2300 family. The 48-port configuration addresses denser server racks; the 32-port comparison is relevant when identifying an existing lower-density installation rather than selecting a current replacement.
N2K-C2348UPQ-10GE provides 1/10GbE host interfaces, whereas the current N9K-C93180YC-FX3 replacement supports 1/10/25GbE server-facing interfaces. The discontinued extender matches existing parent-managed 10GbE installations. N9K-C93180YC-FX3 addresses a 25GbE server refresh, with the transition treated as a switching-architecture migration rather than an identical spare substitution.
N2K-C2348UPQ-10GE supports SFP-10G-SR and SFP-10G-LR on its host interfaces, with QSFP-40G-SR4 and QSFP-40G-SR-BD among its fabric-interface options. Host and fabric media serve different connections and are not interchangeable selections. Specify both link ends, fiber type, reach, and parent-switch compatibility when assembling the optical bill of materials.
N2K-C2348UPQ-10GE supports redundant internal supplies, including N2200-PAC-400W and N2200-PAC-400W-B for AC input, plus N2200-PDC-400W and N2200-PDC-350W-B for DC input. NXA-PHV-500W and NXA-PHV-500W-B provide additional high-voltage input options. Supply selection must match the input service and the chassis airflow configuration, so the installed supply PID belongs on the order confirmation.
