N3K-C3548-X-SPL3 is a managed Layer 3 data center switch with 48 fixed SFP+ interfaces for 1G or 10G connections. The Nexus 3548-X uses the same fixed interfaces for server-facing and upstream connectivity rather than a removable uplink card, so port allocation follows the rack design. This non-PoE, 1U rack-mount chassis connects servers and network devices rather than powered copper endpoints. Software entitlements distinguish routing and latency-feature configurations without changing the connector layout. The discontinued N3K-C3548-X-SPL3A adds the Algo Boost promotional bundle, making software scope the distinction between these two legacy configurations. For an existing installation, the hardware identity and the purchased feature entitlements need to match independently; the chassis name alone does not establish which optional features are licensed.
N3K-C3548-X-SPL3 price for new stock is $45,071.65. N3K-C3548-X-SPL3 refurb price is $25,373.25. N3K-C3548-X-SPL3 is in stock and available for next-day dispatch. (terms applied)

960 Gbps switching capacity and 720 Mpps forwarding support line-rate Layer 2 and Layer 3 traffic across the fixed interfaces. 213W maximum draw sets the upper power-planning figure, while 112W typical operation provides a separate reference for normal operation. Routing depends on the installed software entitlement: Base supports Static, RIPv2, OSPFv2 limited to 256 routes, and EIGRP Stub; LAN Enterprise adds advanced OSPFv2, EIGRP, BGP, and VRF-Lite. N3K-C3548-X-SPL3 carries 4 GB DRAM and 4 GB bootflash for control-plane software and stored images. Normal mode accommodates 24000 IPv4 unicast routes and 64000 MAC addresses, separately from the Base OSPF limit. The Nexus 3500 design provides 18 MB of packet buffering in 6 MB groups shared by 16 ports, so burst traffic shares resources within each group. Frames up to 9216 bytes support jumbo-MTU configurations, while SNMP and XML/NETCONF provide interfaces for external management systems.
ORM Systems offers N3K-C3548-X-SPL3 new sealed or certified refurbished, with up to a 3-year extended warranty for new units, up to 1 year for certified refurbished units, and 30-day returns on either condition; terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, every port linking at rated speed, optics bay recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. Specify the required condition and quantity on the purchase order. POs are accepted, with Net-30 for government, RMA with advance replacement, and regional stock and RMA across the UK, EU, US, and MEA for enterprise and volume orders.

When moving routing boundaries into server racks, count routed physical interfaces, SVIs, PortChannels, and subinterfaces together rather than sizing only VLAN gateways. The combined Layer 3 interface limit is 1024. Inventory the required interface types and confirm the applicable routing entitlements before specifying the purchase order.
When matching replacements across racks with different hot-aisle orientations, cooling direction must match the installation. NXA-FAN-30CFM-F and N2200-PAC-400W support port-side exhaust; NXA-FAN-30CFM-B and N2200-PAC-400W-B support port-side intake. Record the required airflow configuration on the purchase order rather than relying on the chassis PID alone.
When preparing replacement hardware before a maintenance window, two USB ports support local staging while Power On Auto Provisioning and Python scripting provide automation options. Keep staging separate from the production configuration, and specify the intended boot and provisioning process before releasing the hardware purchase order.
Cisco support beyond January 2027
N3K-C3548-X-SPL3 reaches its last date of support on January 31, 2027. N3K-C3548P-XL is the current replacement for purchases requiring a continuing Cisco hardware lifecycle.
Native uplinks faster than 10G
The 48 fixed SFP+ interfaces run at 1 or 10 Gbps; a removable uplink module cannot add a faster physical interface to this chassis.
PoE-powered copper access endpoints
The fixed data interfaces are SFP+ rather than powered RJ-45 access ports. Devices requiring Ethernet-delivered power need separate PoE access switching outside this chassis.

N3K-C3548-X-SPL3 identifies the Nexus 3548-X 48-port SFP+ Layer 3 promotional configuration. N3K denotes the Nexus 3000 family, C3548 identifies the 48-port Nexus 3548 model, X identifies the enhanced generation, and SPL3 denotes the Layer 3 promotion rather than the separate Layer 3 plus Algo Boost promotion.
N3K-C3548-X-SPL3 is managed through CLI, SNMP, XML/NETCONF, and Cisco DCNM. CLI access uses the serial console, SSHv2, or Telnet, through in-band connectivity or the dedicated Ethernet management interface. SNMP versions 1, 2, and 3 are supported, while Python scripting and Power On Auto Provisioning provide automation paths.
Yes, N3K-C3548-X-SPL3 ended Cisco sales on January 31, 2022, and reaches its last date of support on January 31, 2027. Vulnerability and security support ended January 30, 2025, and service-contract renewal ended April 28, 2026. N3K-C3548P-XL is the current replacement rather than another discontinued 3548-X promotional configuration.
ORM Systems offers N3K-C3548-X-SPL3 new sealed or certified refurbished, with up to a 3-year extended 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 cannot extend beyond its last date of support, January 31, 2027.
N3K-C3548-X-SPL3 supports legacy Base and LAN Enterprise feature licenses, NX-OS Essentials or Advantage subscriptions with three-year minimum terms, and nonexpiring perpetual Advantage on compatible releases. Feature-based licenses are discontinued ordering options. A subscription is not the only licensing path; the order must distinguish hardware condition from the software entitlement supplied.
N3K-C3548-X-SPL3 supports Static, RIPv2, OSPFv2, EIGRP, and BGP according to its installed license. Base limits OSPFv2 to 256 routes and EIGRP to stub operation; LAN Enterprise adds advanced routing and VRF-Lite. The normal-mode IPv4 unicast route capacity is 24000 routes, separate from the Base OSPF limit.
SFP-10G-SR and SFP-10G-LR are 10G optical options for N3K-C3548-X-SPL3, using multimode and single-mode fiber respectively. The 48 fixed SFP+ cages support 1 or 10 Gbps operation; the transceiver, fiber type, and remote interface must match. Optical components belong on the purchase order rather than being assumed present in every cage.
Yes, N3K-C3548-X-SPL3 supports dual redundant hot-swappable power supplies with AC or DC options. N2200-PAC-400W and N2200-PAC-400W-B are the AC airflow variants; N2200-PDC-400W and N3K-PDC-350W-B are DC variants. Airflow must match across the installed cooling components, and the order must identify the required power configuration rather than assuming one from the promotional PID.
The Nexus 3548-X consumes 112W typically and 213W at maximum, so electrical planning must distinguish typical operation from maximum draw. These figures describe the complete switch rather than the rating of an individual N2200-PAC-400W. Redundancy does not turn the two installed supply ratings into the switch's operating consumption.
The Nexus 3548-X has 4 GB DRAM and 4 GB bootflash, rather than the extended memory of the XL generation. Normal forwarding mode supports 64000 MAC addresses. Packet buffering totals 18 MB, arranged as 6 MB shared among each group of 16 ports rather than dedicated buffering per interface.
N3K-C3548-X-SPL3A adds the Algo Boost promotional bundle to the Layer 3 configuration offered by N3K-C3548-X-SPL3. N3548-ALGK9 covers warp mode, warp SPAN, and NAT. Both configurations are discontinued: the former addresses legacy Algo Boost requirements, while the latter addresses legacy routed-switching requirements without that additional promotional bundle.
N3K-C3548-X-SPL3 enables 48 SFP+ ports, whereas N3K-C3524-X-SPL3 enables 24. The 24-port configuration can expand through N3548-24P-UPG= licensing rather than an additional network card. Both are discontinued; existing deployments requiring all ports active differ from legacy installations needing only the smaller licensed port population when specifying replacement stock.
N3K-C3548P-XL provides 16 GB DRAM and 16 GB bootflash, compared with 4 GB each on N3K-C3548-X-SPL3. The X promotional configuration is discontinued, while N3K-C3548P-XL is its current replacement. Matching an existing X installation and purchasing an extended-memory XL replacement are therefore different hardware requirements, even when the required port population is unchanged.
