N3K-C3548P-10GX is a managed 1RU data center switch with 48 fixed SFP+ ports that operate at 1 or 10 Gbps. The Cisco Nexus 3548-X belongs to the Nexus 3500 platform and runs Cisco NX-OS for top-of-rack Layer 2 and licensed Layer 3 deployments. Its fixed port design suits SFP+ server, storage and aggregation links rather than copper access endpoints or PoE devices. The chassis supports AC or DC power-supply choices, port-side exhaust or port-side intake airflow, four hot-swappable fans and a 10/100/1000 management port. N3K-C3524P-10GX uses the same Nexus 3524-X generation with 24 enabled SFP+ ports instead of 48.
N3K-C3548P-10GX price for new stock is $5,827.50, a 79.6% saving from the Cisco list price of $28,573.00. N3K-C3548P-10GX refurb price is $325.50. N3K-C3548P-10GX is in stock and available for next-day dispatch. (terms applied)

960 Gbps switching capacity and 720 Mpps forwarding support line-rate traffic on all 48 SFP+ ports. 213W maximum power draw, 4 GB DRAM, 4 GB bootflash and an 18 MB shared packet buffer define the Nexus 3548-X hardware profile. N3K-C3548P-10GX runs Cisco NX-OS with VLANs, LACP, PVRST+, MSTP, RSTP, SSHv2, Telnet, SNMP, XML NETCONF, POAP, Cisco DCNM and in-band or out-of-band management. Default software is a Layer 2 feature set; N3548-BAS1K9 adds Layer 3 Base functions including Static, RIPv2, OSPFv2 limited to 256 routes, EIGRP stub, HSRP, VRRP, PIM-SM, SSM and MSDP. N3548-LAN1K9 adds LAN Enterprise routing, and N3548-ALGK9 enables NAT, warp mode and warp SPAN. The platform is not a stackable access switch, and the 48 data ports remain fixed SFP+ cages with no modular uplink bay.
N3K-C3548P-10GX is available from ORM Systems in new sealed and certified refurbished conditions. Certified refurbished units are inspected and bench-tested, with every SFP+ port linked at rated speed, optics bay recognition, PSU status, fan status, clean boot, firmware verified and configuration wiped to factory default. Specify airflow direction, PSU type, optics, license PIDs and condition on the PO. New sealed orders can carry up to a 3-year extended warranty; certified refurbished orders carry up to 1 year. Returns are 30 days on every condition; terms apply. PO accepted, Net-30 for government, RMA with advance replacement, and regional stock or RMA support in the UK, EU, US and MEA.

In a multi-tenant cloud data center, service providers deploy the N3K-C3548P-10GX Nexus 3548-X 48 SFP+ Enhanced switch as the spine in a leaf-spine architecture to support VXLAN-based segmentation and 1.92 Tbps non-blocking throughput. This delivers sub-400 ns end-to-end latency, 480 Gbps per device oversubscription-free performance, and seamless capacity scaling—ensuring predictable application SLAs and rapid tenant onboarding.
A high-frequency trading firm integrates N3K-C3548P-10GX Nexus 3548-X 48 SFP+ Enhanced switches to interconnect market data feeds, order-matching engines, and risk management servers on the trading floor. Achieving deterministic sub-400 ns switching latency and hardware timestamping, this solution reduces execution slippage, accelerates trade lifecycles, and preserves microsecond-level competitiveness.
In a hyperscale AI research environment, data scientists use the N3K-C3548P-10GX Nexus 3548-X Enhanced switch to aggregate 48 dual-10GbE GPU server links into a lossless RDMA fabric, backed by hardware-based QoS and microburst protection. This architecture boosts distributed training throughput by over 30%, maximizes GPU utilization, and delivers a scalable, low-latency transport layer for advanced machine learning workflows.
High-frequency trading or HPC racks using 10G fiber can standardize on 48 fixed SFP+ ports, 960 Gbps switching capacity and 720 Mpps forwarding. Specify the airflow direction, AC or DC power supply type, and the exact SFP-10G-SR or SFP-H10GB-CU1M media before the PO.
Data center rows that need routed SVIs or protocol adjacencies should separate the chassis from the license line. The default software is Layer 2; add N3548-BAS1K9 for Static, RIPv2 and limited OSPFv2, then N3548-LAN1K9 where BGP or VRF-Lite is required.
Installed Nexus 3548-X environments approaching hardware support cutoff need matched spares before 31 January 2027. Record fan direction, power input, optics, and any N3548-ALGK9 or routing licenses already in use so replacements match the production configuration before condition is selected.
25G or 100G links
The chassis provides fixed 1/10G SFP+ ports and no native 25G or 100G cages, so higher-speed leaf ports require another platform.
Long Cisco support runway
Cisco support for the hardware ends 31 January 2027; the forward replacement is N3K-C3548P-XL for the same 48-port SFP+ role with extended memory.
Bundled advanced routing
The base chassis carries the default Layer 2 feature set; Layer 3 Base, LAN Enterprise and Algo Boost functions require separate license PIDs.
Copper access switching
The switch has zero RJ-45 access ports and uses SFP+ cages for data links; copper endpoints need transceivers or a different access platform.

Strong Nexus platform.
N3K-C3548P-10GX is a Cisco Nexus 3548-X 1RU data center switch with 48 fixed SFP+ ports that operate at 1 or 10 Gbps. The chassis runs Cisco NX-OS, supports dual hot-swappable power-supply bays, and fits Nexus 3500 platform top-of-rack designs.
N3K-C3548P-10GX is the exact orderable chassis PID for the Nexus 3548-X Switch with 48 SFP+ ports. The reliable decoded elements are the Nexus 3548-X product identity, the 48-port SFP+ configuration, and the 10GX orderable chassis suffix used for this enhanced model.
N3K-C3548P-10GX is managed through the console port, the 10/100/1000 management port, or in-band switch management. Documented management paths include CLI access with SSHv2 or Telnet, SNMP v1/v2/v3, XML NETCONF, POAP, Cisco DCNM, syslog, RADIUS, TACACS+ and Cisco Call Home.
N3K-C3548P-10GX is end of sale, with the final Cisco order date on 31 January 2022 and Last Date of Support on 31 January 2027. N3K-C3548P-XL is the named replacement for the 48-port Nexus 3548-X chassis.
N3K-C3548P-10GX carries Cisco's 1-year limited hardware warranty only within the active Cisco support window ending 31 January 2027. ORM Systems offers new sealed units with up to a 3-year extended warranty, certified refurbished units with up to 1 year, and 30-day returns; terms apply.
N3K-C3548P-10GX needs added licenses for Layer 3 routing beyond the default Layer 2 feature set. N3548-BAS1K9 enables Static, RIPv2, OSPFv2 limited to 256 routes, EIGRP stub, HSRP, VRRP, PIM-SM, SSM and MSDP; N3548-LAN1K9 adds BGP, EIGRP, OSPFv2 and VRF-Lite.
N3K-C3548P-10GX has 48 fixed SFP+ data ports operating at 1 or 10 Gbps. The chassis also has one 10/100/1000 management port, one RS-232 serial console port and two USB ports, which are not counted as access or uplink data ports.
N3K-C3548P-10GX does not support PoE, PoE+ or PoE++ on its data ports. The switch is a 1/10G SFP+ data center platform powered by AC or DC power supplies, not an access switch for directly powering phones, cameras or wireless access points.
N3K-C3548P-10GX is not a stacking switch and no stacking kit or member limit is specified for the Nexus 3548-X. Nexus 3500 software can support features such as vPC, but those features do not turn multiple chassis into a single stackable access-switch system.
The Nexus 3548-X supports 10G SFP+ media such as SFP-10G-SR, SFP-10G-LR, SFP-10G-ER and SFP-H10GB-CU1M direct-attach copper. The platform can also use 1G SFP options such as GLC-T, and 40G connectivity is built from four sequential SFP+ interfaces.
N3K-C3548P-10GX provides 48 fixed SFP+ ports, while N3K-C3524P-10GX is the 24-port Nexus 3524-X configuration. The 48-port model fits fully populated 10G racks; the 24-port model fits smaller Nexus 3500 rows that still need the same SFP+ port class.
N3K-C3548P-XL adds the extended-memory Nexus 3548-XL design with 16 GB system memory and 16 GB bootflash, while N3K-C3548P-10GX has 4 GB system memory and 4 GB bootflash. The XL model is the forward replacement; the 10GX model matches existing Nexus 3548-X deployments.
N3K-C3548-X-SPL3A is a discontinued L3 plus Algo Boost promotional 48-port Nexus 3548-X PID, while N3K-C3548P-10GX is the standard enhanced 48-port Nexus 3548-X chassis PID. The promotional PID suits sites needing those bundled capabilities; 10GX suits sites ordering licenses separately.
