N2K-C2348TQ-E is a parent-managed Layer 2 fabric extender rather than an autonomous data center switch. Its 48 copper host interfaces support 100 Mbps, 1 Gigabit Ethernet and 10GBASE-T, while six fixed 40G QSFP+ fabric interfaces connect server traffic to a compatible Nexus parent switch. The non-PoE design provides server data connectivity in a 1U chassis. Cisco Nexus 2300 fabric extenders operate as remote line cards, with configuration and policy enforcement centralized upstream rather than maintained as independent access switches. The discontinued N2K-C2348TQ also accepts NXA-PHV-500W and NXA-PHV-500W-B power supplies; Cisco Nexus 2348TQ-E excludes those options. That distinction matters when matching a replacement chassis to power hardware already installed in the rack.
N2K-C2348TQ-E price for new stock is $7,045.50, a 57.7% saving from the Cisco list price of $16,668.00. N2K-C2348TQ-E refurb price is $7,087.74. N2K-C2348TQ-E is in stock and available for next-day dispatch. (terms applied)

1440 Gbps hardware switching capacity defines the internal forwarding ceiling, distinct from the bandwidth available through the fabric links. 2160 Mpps forwarding rate defines the packet-processing ceiling. Shared 32 MB packet buffers absorb traffic bursts, while eight hardware queues per port separate traffic classes. Local policing provides 64 policers, and local classification supports 256 ACL entries. N2K-C2348TQ-E uses in-band management through its parent switch, with CLI, Cisco Data Center Network Manager, SNMP and XML NETCONF interfaces available through that parent. VLAN trunks, server-side PortChannel and uplink EtherChannel support traffic attachment and aggregation; independent Layer 3 routing is not a function of the fabric extender. Jumbo-frame support reaches 9216 bytes, setting the frame-size limit for attached workloads. 350W maximum input draw provides the upper figure for rack power planning; the 280W typical figure applies to 30 m copper connections.
ORM Systems supplies N2K-C2348TQ-E in new sealed and certified refurbished condition; specify the condition, quantity and required hardware configuration on the PO. Certified 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, with firmware verified and configuration wiped to factory default. ORM's new-unit warranty is up to a 3-year extended term and certified refurbished coverage is up to 1 year; both conditions include 30-day returns, terms apply, while Cisco's separate 1-year limited hardware warranty is bounded by service ending August 31, 2027. Volume purchases support PO ordering, Net-30 for government and RMA with advance replacement, with regional stock and RMA across the UK, EU, US and MEA.

In multi-tenant cloud and enterprise data centers, the N2K-C2348TQ-E-Nexus 2000 10GT FEX extends 48x1/10T server links over six 40G QSFP uplinks to Nexus 9000 leaf switches. This rack-level fabric delivers consistent low-latency east-west connectivity and seamless VLAN/VXLAN segmentation. Benefit: Accelerated VM provisioning, centralized NX-OS policy enforcement, 70% reduction in top-of-rack cabling, and linear scale-out performance.
In financial services trading floors, the N2K-C2348TQ-E-Nexus 2000 10GT FEX provides 48x10G direct server attachments with line-rate forwarding and sub-microsecond latency, aggregated via six 40G QSFP uplinks to low-latency core switches. This architecture ensures deterministic packet delivery and real-time market data processing. Benefit: Maximized trade execution speed, improved market data throughput, and simplified rack-level cabling footprint.
In large enterprise campuses, the N2K-C2348TQ-E-Nexus 2000 10GT FEX aggregates 48x1/10G access links from WLAN controllers and edge switches into the core with six 40G QSFP uplinks. Integrated Virtual PortChannel (vPC) provides active-active uplink redundancy, while Cisco ACI and NX-API enable centralized policy automation. Benefit: Streamlined operations, enhanced reliability, reduced edge switch count, and cost-effective network consolidation.
When an installed N2K-C2232TM-E fabric extender needs replacement, the retirement deadline already matters: Cisco support for that older model ended September 30, 2025. Preserve the fabric-extender architecture only after validating the existing parent-switch compatibility and software release, then specify the required airflow and power configuration before issuing the PO.
When a rack's servers share upstream fabric connections, host-facing bandwidth and fabric bandwidth need separate sizing. The fabric reaches 240 Gbps in each direction, with 2:1 oversubscription. Review the server traffic profile and planned active links, then specify the fabric-link population and parent-side termination before issuing the PO.
When staging a spare fabric extender for an existing Nexus 9300 or 9500 installation, confirm the parent software before scheduling the bench session. N2K-C2348TQ-E requires NX-OS 9.2.1 as the minimum for those parent families. Specify the compatible parent model and intended release with the spare order, then verify fabric-link initialization before acceptance.
Independent switching without a parent
N2K-C2348TQ-E operates as a remote line card, not an autonomous switch. N9K-C93108TC-FX3P is the current migration model; replacing the fabric extender requires an architecture review.
100G upstream connections
The six built-in fabric interfaces support 40G rather than 100G. N9K-C93108TC-FX3P provides six 100G connections and retains 48 copper host-facing ports with additional speed options.
Passive copper fabric cables
Passive copper fabric cables are unsupported. QSFP-H40G-ACU7M and QSFP-H40G-ACU10M provide supported active copper alternatives at 7 m and 10 m respectively for compatible parent connections.
Copper FCoE links beyond 30 m
Copper FCoE connectivity is limited to 30 m using Category 6a or Category 7 cabling. A longer cable route falls outside that supported configuration.

N2K-C2348TQ-E identifies the Cisco Nexus 2348TQ-E 10GBASE-T Fabric Extender. N2K corresponds to the Nexus fabric-extender family, C2348TQ identifies the copper host-interface model, and -E selects the 2348TQ-E hardware variant. The configuration has 48 100M/1/10GBASE-T host ports, six 40G QSFP+ fabric interfaces, two power supplies and three fan modules.
N2K-C2348TQ-E is managed in-band through its parent Nexus switch using CLI, Cisco Data Center Network Manager, SNMP and XML NETCONF; CiscoWorks is also supported. Management is centralized upstream rather than configured through an independent local management interface. SNMP versions 1, 2 and 3 support monitoring through the parent-managed environment.
Yes, N2K-C2348TQ-E reached end-of-sale on August 24, 2022, and its last date of Cisco support is August 31, 2027. Software maintenance ended August 24, 2023, and vulnerability support ended August 23, 2025. Existing service-contract renewals end November 22, 2026; support requires applicable entitlement.
ORM Systems offers N2K-C2348TQ-E new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Both conditions include 30-day returns; terms apply. Cisco's separate platform warranty is 1-year limited hardware, and Cisco service for this model ends August 31, 2027.
N2K-C2348TQ-E supports compatible Nexus 5500, 5600, 6000, 9300 and 9500 parent switches. Minimum software is NX-OS 7.3(0)N1(1) for the 5500, 5600 and 6000 families, or NX-OS 9.2.1 for the 9300 and 9500 families. Confirm the particular parent model and intended topology before specifying the fabric extender.
N2K-C2348TQ-E supports N2200-PAC-400W, N2200-PAC-400W-B, N2200-PDC-400W and N2200-PDC-350W-B power supplies. The configured chassis includes two supplies for 1+1 redundancy, with AC or DC input selected to match the installation. NXA-FAN-30CFM-F matches port-side exhaust, while NXA-FAN-30CFM-B matches port-side intake; confirm the supply and fan airflow together.
The Nexus 2348TQ-E uses six fixed 40G QSFP+ fabric interfaces with separately selected optics or active cables. Supported optical choices include QSFP-40G-SR4 and QSFP-40G-SR-BD. CVR-QSFP-SFP10G supports adapted 10G connections. Match the selected fabric-link hardware to the parent port type, cabling and intended connection speed before ordering.
No, N2K-C2348TQ-E provides Layer 2 host attachment as a fabric extender, not independent Layer 3 routing. Routing capabilities belong to the parent switch and its software configuration. The fabric extender supports VLAN trunks and server-side PortChannel, so routed-access requirements must be evaluated against the upstream switch rather than this chassis alone.
Yes, the Nexus 2348TQ-E supports FCoE over its copper host interfaces at distances of 30 m using Category 6a or Category 7 cables. FCoE operation also depends on a compatible parent-switch configuration. Confirm the measured cable route and parent capabilities before treating a copper server connection as a unified-fabric link.
Yes, the Nexus 2348TQ-E uses a 1U chassis for rack installation and measures 43.7 mm high, 439.4 mm wide and 433.6 mm deep. Its weight is 8 kg. Confirm cabinet clearance, cable routing and the selected airflow orientation before specifying the rack position and installation hardware on the order.
N2K-C2348TQ-E is the named replacement for N2K-C2232TM-E, N2K-C2232TM-E++, N2K-C2232TM-E-10G=, N2K-C2232TM-E-10GE, N2K-C2332TQ, N2K-C2332TQ-10GT, N2K-C2332TQ-10GT=, N2K-C2348TQ, N2K-C2348TQ++, N2K-C2348TQ-10GE and N2K-C2348TQ-10GE=. Those PIDs reached end-of-sale on September 9, 2020, and Cisco support ended September 30, 2025. N2K-C2348TQ-E is also discontinued; N9K-C93108TC-FX3P is the current migration model.
N2K-C2348TQ accepts NXA-PHV-500W and NXA-PHV-500W-B power supplies, while N2K-C2348TQ-E does not. N2K-C2348TQ is discontinued, with Cisco support ended September 30, 2025. N2K-C2348TQ-E accommodates supported AC or low-voltage DC installations; the older model's additional power compatibility matters when identifying equipment already installed in an existing rack.
N2K-C2348TQ-E provides 48 copper host interfaces, compared with 32 on N2K-C2332TQ. N2K-C2332TQ is discontinued, and Cisco support ended September 30, 2025. The 48-port model addresses existing installations needing greater copper attachment density; the 32-port model remains a reference for identifying lower-density legacy chassis rather than a current rollout alternative.
N9K-C93108TC-FX3P provides six 100G connections, compared with six 40G fabric interfaces on N2K-C2348TQ-E. N2K-C2348TQ-E is discontinued, while N9K-C93108TC-FX3P is the current migration model. The fabric extender addresses maintenance of an existing 40G fabric architecture; the successor addresses purchase plans requiring 100G upstream connections and a replacement architecture.
