N2K-C2348TQ-10G-E is a parent-controlled Layer 2 fabric extender with 48 copper server ports supporting 100 Mbps, 1 Gbps and 10 Gbps, plus six fixed 40G QSFP+ fabric interfaces. The non-PoE, 1U chassis belongs to the Nexus 2300 family and operates as a remote line card rather than an independent switch. Its fabric interfaces connect to an upstream Nexus parent, while the RJ-45 interfaces attach servers. The Nexus 2348TQ-E supports rack-server and blade-server environments where centralized switching control is already part of the architecture. Compared with the discontinued N2K-C2332TQ, which has 32 copper host ports, this model provides greater server-port density without changing the host connection type.

1440 Gbps hardware forwarding capacity describes internal processing rather than available upstream fabric bandwidth. 2160 Mpps forwarding performance accompanies that capacity, while 32 MB of shared buffers accommodates traffic bursts. Eight hardware queues per port support traffic classification, and 64 local policers provide traffic-rate controls. Local classification supports 256 ACL entries; local multicast replication supports 8000 entries. Jumbo-frame support extends to 9216 bytes. N2K-C2348TQ-10G-E exposes management through the parent using CLI, SNMP, XML/NETCONF and Cisco Data Center Network Manager. Independent Layer 3 routing is not provided by the fabric extender. 350W maximum input consumption establishes the electrical allowance for the chassis, distinct from the output rating of an installed power supply. The operating temperature range of 0°C to 55°C sets the environmental limit for equipment placement. UL 60950-1, IEC 60950-1 and Class A emissions compliance address equipment safety and electromagnetic compatibility.
Specify N2K-C2348TQ-10G-E in new sealed or certified refurbished condition, and identify the required power configuration and included components on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, PSU status and fan status; firmware is verified and configuration is wiped to factory default. ORM's new units carry up to 3-year extended warranty, certified refurbished units carry up to 1 year, and every condition has 30-day returns, with terms applying. For enterprise and volume orders, PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA coverage across the UK, EU, US and MEA are available.

When consolidating copper-connected servers into an existing fabric-extender design, the available fabric bandwidth must be considered separately from server connection speeds. The Nexus 2300 architecture supports 2:1 oversubscription, so simultaneous traffic demand remains an upstream sizing consideration. Specify the required fabric connections and traffic allowance before placing the PO.
When purchasing a replacement for an installed rack, matching airflow is a component-level requirement. Port-side exhaust assemblies pair N2200-PAC-400W supplies with NXA-FAN-30CFM-F fan modules; port-side intake assemblies use the corresponding reverse-airflow components. Mixing airflow directions can produce an error condition and overheating. Specify the installed component PIDs before ordering a spare.
When staging a replacement before rack installation, the dedicated HDMI management/console port provides a physical service connection rather than a server interface. Keep that service connection separate from the fabric-link acceptance plan. Specify the parent-switch software release, required service access and acceptance procedure before approving the purchase order.
Independent switching without a parent
The Nexus 2348TQ-E requires an upstream Nexus parent and cannot operate as an independent switch. N9K-C93108TC-FX3P is the current replacement, but changes the deployment architecture.
100G upstream fabric connections
The fixed fabric interfaces support 40G, not 100G. N9K-C93108TC-FX3P provides six 100G ports and retains 48 copper access ports, but is not a direct fabric-extender substitution.
NX-OS 10.6 parent software
Nexus 2000 fabric extenders are supported through NX-OS 10.5(x), but are unsupported beginning with 10.6(3)F. A parent upgrade beyond that boundary requires a different access design.

N2K-C2348TQ-10G-E identifies the Nexus 2348TQ-E fabric extender with 48 copper host ports and six 40G QSFP fabric interfaces. The 10G segment corresponds to 10GBASE-T host connectivity, while the final E belongs to the 2348TQ-E model designation. Keep the complete PID when matching replacement hardware.
N2K-C2348TQ-10G-E is managed through its parent Nexus switch using CLI, SNMP, XML/NETCONF and Cisco Data Center Network Manager. A local HDMI management/console connection provides service access. Configuration and feature selection belong to the parent-managed system rather than an independent access-switch control plane.
N2K-C2348TQ-10G-E reached end of sale on August 24, 2022, and vulnerability/security support ended August 23, 2025. The last date of support is August 31, 2027, subject to applicable service entitlement. N9K-C93108TC-FX3P is the current replacement, requiring a migration assessment rather than an assumed direct swap.
ORM Systems offers N2K-C2348TQ-10G-E new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days for either condition; terms apply. Cisco's separate 1-year limited hardware warranty is bounded by the August 31, 2027 last date of support.
N2K-C2348TQ-10G-E supports fabric-link options including QSFP-40G-SR4, QSFP-40G-LR4 and QSFP-40G-SR-BD optics, plus active copper cables such as QSFP-H40G-ACU7M. Passive copper fabric cables are unsupported. Match the selected connection to the parent interface and fiber plant, and specify optics or cabling separately from the chassis.
The Nexus 2348TQ-E accepts N2200-PAC-400W, N2200-PAC-400W-B, N2200-PDC-400W and N2200-PDC-350W-B power supplies. The configured chassis supports redundant power, but the selected input type and airflow determine the assembly. Match NXA-FAN-30CFM-F or NXA-FAN-30CFM-B fan modules to the supply airflow and specify the required configuration on the PO.
No, N2K-C2348TQ-10G-E is a parent-controlled fabric extender, not a standalone Layer 3 switch. Its server interfaces extend the upstream Nexus system, and feature availability follows that parent-managed architecture. Routing requirements must therefore be addressed at the parent rather than treated as a local license upgrade on the extender.
N2K-C2348TQ-10G-E= is the spare chassis without power supplies or fans, while N2K-C2348TQ-10G-E identifies the configured chassis form. Both are discontinued ordering forms. The configured form suits a complete assembly requirement; the spare suits an existing installation only when compatible power and cooling components will be retained.
N2K-C2348TQ-10G-E provides 48 copper host ports, whereas the discontinued N2K-C2332TQ provides 32. Both use 10GBASE-T host connectivity within the Nexus fabric-extender architecture. The higher-density model addresses larger existing server-port requirements; N2K-C2332TQ remains relevant when identifying an installed lower-density system, not as a current migration destination.
N2K-C2348TQ-10G-E has six 40G fabric interfaces, while N9K-C93108TC-FX3P provides six 100G interfaces. The former is a discontinued fabric extender; the latter is the current replacement switch. Existing parent-controlled installations may require replacement-in-kind hardware, while migration buyers must assess the replacement's different switching architecture and connectivity.
The Nexus 2348TQ-E replaces discontinued 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 older units reached end of sale September 9, 2020. Their host-port counts, fabric connections and power arrangements must not be assumed interchangeable when planning replacement assemblies.
The Nexus 2348TQ-E occupies 1U and measures 43.7 mm high, 439.4 mm wide and 433.6 mm deep. Its maximum listed weight is 8 kg. Include mounting hardware in the assembly check; N2300-ACC-KIT= is the accessory kit containing rack-mount hardware, grounding hardware and an ESD strap.
