N2K-C2248TP is a Layer 2 fabric extender with 48 100/1000BASE-T copper server interfaces and four fixed 10G SFP+ fabric uplinks. The non-PoE chassis operates as a remote line card for a compatible parent Nexus switch, not as an independent access switch. Cisco Nexus 2000 Series Fabric Extenders place server connections at the rack while keeping configuration and policy enforcement upstream. The 1U chassis fits top-of-rack and end-of-row server-access arrangements. Compared with N2K-C2248TP-1GE, the configurable Cisco Nexus 2248TP permits power-input and airflow selection instead of prescribing AC power with standard port-side exhaust airflow. Confirm the parent-switch combination and selected chassis configuration before committing the hardware order.
N2K-C2248TP price for new stock is $11,954.25, a 50% saving from the Cisco list price of $23,908.50. N2K-C2248TP refurb price is $2,515.54. N2K-C2248TP is in stock and available for next-day dispatch. (terms applied)

176 Gbps switching capacity and 131 Mpps forwarding support the host and fabric interfaces. A 1.2:1 oversubscription ratio applies between the host connections and fabric bandwidth, so traffic planning must account for simultaneous server demand. N2K-C2248TP provides eight hardware queues per port and 64 local policers for per-port QoS configuration. Cisco EtherChannel hashing or static port pinning controls uplink traffic placement, while PortChannel supports server connections on the Nexus 2200 platform. Local multicast replication supports 8000 entries, and local classification supports 256 ACL entries. Management runs in-band through the parent switch using CLI, SNMP, XML interfaces, Cisco DCNM, or CiscoWorks. Parent software and topology determine which inherited features are available; the fabric extender does not supply an independent routing control plane.
ORM supplies N2K-C2248TP new sealed or certified refurbished; specify condition, quantity, input power, airflow, and fabric-link accessories on the PO. 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 wiped to factory default. ORM warranty is up to 3-year extended for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply. Enterprise and volume orders accept POs, Net-30 for government, and RMA with advance replacement through UK, EU, US, and MEA regional stock and RMA operations.

When an existing Nexus 9000 environment needs additional server attachment points, fabric extenders support the server vPC topology rather than every dual-homed arrangement available elsewhere in the family. Before the PO, confirm the exact parent model, software release, available fabric interfaces, and intended server connection topology.
When standardized racks place network ports toward a particular aisle, airflow direction becomes an order-level choice. Pair N2200-PAC-400W with N2K-C2248-FAN for port-side exhaust, or N2200-PAC-400W-B with N2K-C2248-FAN-B for port-side intake. Specify matching component PIDs and the intended aisle orientation on each PO.
When a lab will validate jumbo-frame server traffic before a rack rollout, all ports support frames as large as 9216 bytes. Acceptance testing also needs the intended parent-switch configuration and fabric connection. Define the frame-size test, parent software image, and link media before specifying the staging order.
Independent operation without a parent
N2K-C2248TP operates as a remote line card, not an independent switch. N9K-C9348GC-FXP is the migration endpoint; reassess its management requirements and different uplink configuration.
10G copper server interfaces
Server-facing copper interfaces on N2K-C2248TP support 100 Mbps or 1 Gbps only; the 10G SFP+ interfaces connect to the parent fabric rather than servers.
Cisco-backed hardware support
Cisco support for N2K-C2248TP ended November 30, 2021. The migration endpoint is N9K-C9348GC-FXP; the interim replacement N2K-C2248TP-E is also discontinued.

N2K-C2248TP identifies the Nexus 2248TP 1GE fabric extender: N2K denotes the Nexus 2000 family, and C2248TP identifies the model. Its configuration is 48 100/1000BASE-T host interfaces plus four 10GE fabric interfaces. Power input and airflow are selectable when ordering, rather than fixed by an additional configuration suffix.
The Nexus 2000 fabric extender is managed through its parent Nexus switch using CLI, Cisco DCNM, CiscoWorks, SNMP v1/v2/v3, and XML/NETCONF interfaces. Management travels in-band across the fabric connection rather than through an independent access-switch management environment. Specify the parent management system and compatible software before ordering.
N2K-C2248TP is discontinued: end of sale was November 2, 2016, and Cisco support ended November 30, 2021. Its immediate replacement, N2K-C2248TP-E, is also discontinued, with support scheduled to end August 31, 2027. The forward migration chain leads to N9K-C9348GC-FXP rather than another currently sold 2248TP fabric extender.
ORM offers N2K-C2248TP new sealed or certified refurbished, with up to 3-year extended warranty on new units and up to 1 year on refurbished units. Returns are available for 30 days on every condition; terms apply. Cisco’s original 1-year limited hardware warranty and service ended November 30, 2021.
N2K-C2248TP supports SFP-10G-SR and SFP-10G-LR optical connections or SFP-H10GB-CU1M copper attachment through its four fixed 10G SFP+ fabric interfaces. Select media for the parent interface and required reach, and include the required link components in the order. These connections join the parent fabric rather than adding 10G server interfaces.
Yes, N2K-C2248TP includes two power supplies with 1:1 redundancy, selected for input power and airflow. Options are N2200-PAC-400W, N2200-PAC-400W-B, N2200-PDC-400W, and N2200-PDC-350W-B. Match the selected configuration to N2K-C2248-FAN or N2K-C2248-FAN-B airflow, and specify the required component PIDs rather than assuming every order has the same AC configuration.
N2K-C2248TP provides 176 Gbps hardware forwarding capacity and 131 Mpps forwarding performance. Its fabric interfaces provide 40 Gbps in each direction, or 80 Gbps full duplex, with 1.2:1 oversubscription. Size the fabric connection for the expected concurrent server traffic rather than treating every host connection as having dedicated upstream bandwidth.
No, the Nexus 2248TP is Layer 2 server-access hardware, not an independent Layer 3 routing switch. Features and policy enforcement come from the parent Nexus switch, so parent routing capability must not be attributed to the fabric extender itself. Specify the parent’s routing requirements and software separately from this hardware order.
N2K-C2248TP provides 48 copper host interfaces, while N2K-C2224TP provides 24; both support 100/1000BASE-T server attachment. Both models are discontinued, so neither is a current-generation migration target. The former matches denser installed server racks, while the latter matches a lower-density existing fabric that requires like-for-like hardware sparing.
N2K-C2248TP permits power-input and airflow selection, whereas N2K-C2248TP-1GE specifies AC power with standard port-side exhaust airflow. Both are discontinued fabric extenders with the same copper host-interface arrangement. The configurable PID suits matching an existing power and airflow specification; the fixed AC configuration suits standard-airflow AC racks needing equivalent replacement hardware.
N9K-C9348GC-FXP offers four 10/25G interfaces plus two 40/100G QSFP28 interfaces, whereas N2K-C2248TP offers four 10G fabric interfaces. Both have 48 copper 100M/1G interfaces. The discontinued fabric extender suits installed-fabric sparing; the migration switch suits a redesign requiring the higher-speed uplink configuration rather than another replacement fabric extender.
