N3K-C3548P-FA-L3A is an ultra-low-latency Layer 3 data center switch with 48 fixed 1/10G SFP+ interfaces and an L3 plus Algo Boost software bundle. The non-PoE design provides optical and direct-attach connectivity rather than powered copper access connections. Its fixed interface bank accommodates both downstream and upstream links without a removable uplink card, so the port allocation belongs in the connection schedule. The Cisco Nexus 3548 occupies a 1U rack position and uses port-side exhaust airflow, with cooling air entering through the power-supply side. The discontinued N3K-C3548P-FD-L3A differs by using DC input instead of AC. Within the Nexus 3500 family, this configuration combines the original hardware generation with advanced routing and Algo Boost functionality.

960 Gbps switching capacity and 720 Mpps forwarding provide the throughput envelope for interface planning. 265W maximum power consumption establishes the upper electrical allowance; the typical operating figure is 152W. N3K-C3548P-FA-L3A carries 4 GB of DRAM and 2 GB of flash for control-plane operation and local software storage. Normal mode supports 64000 MAC entries and 24000 IPv4 unicast routes, while forwarding-mode selection changes those limits. OSPFv2, EIGRP and BGP are available through LAN Enterprise licensing; the Base license also provides static routing, RIPv2 and multicast functions. Management combines serial console access, CLI sessions over SSHv2 or Telnet, SNMP, XML NETCONF and DCNM. Two N2200-PAC-400W supplies provide redundant AC power, while four NXA-FAN-30CFM-F fans maintain the specified airflow. The chassis has no removable network-module bay for adding a different interface class.
ORM Systems supplies N3K-C3548P-FA-L3A new sealed or certified refurbished, with up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition; terms apply. Certified refurbished units are inspected and bench-tested for power-on, POST, clean boot, rated-speed port links, optics bay recognition, PSU status and fan status, with firmware verified and configuration wiped to factory default. Specify condition, license entitlements and link accessories on the PO; Cisco's original 1-year limited hardware warranty and service ended October 31, 2021. For enterprise and volume orders, POs are accepted, government buyers receive Net-30, and RMA includes advance replacement across UK, EU, US and MEA.

When reproducing an existing latency-sensitive environment, warp mode offers latency as low as 200 ns with reduced forwarding-table capacity. Run the intended traffic mix and configuration through staging rather than selecting the mode from latency alone. Specify the required operating mode and acceptance tests before approving the purchase order.
When migrating an established routed configuration, the combined limit of 1024 Layer 3 interfaces covers routed ports, switch virtual interfaces, PortChannels and subinterfaces. Inventory those interface types together rather than treating each category as an independent allowance. Specify the configuration inventory and confirm its combined interface count before ordering replacement hardware.
Active Cisco hardware support coverage
Cisco hardware support ended October 31, 2021. N3K-C3548P-XL is the current successor in the replacement chain; specify that model when planning a supported-generation migration.
Dedicated 40G QSFP uplink cages
The chassis has SFP+ cages rather than QSFP cages. Logical 40G connectivity combines four sequential interfaces, so a dedicated single-cage QSFP connection is unavailable.

N3K-C3548P-FA-L3A identifies a Nexus 3548 L3 and Algo Boost bundle with forward airflow and AC power. N3K denotes the Nexus 3000 family, C3548P identifies the 48-port SFP+ model, FA denotes port-side exhaust with AC input, and L3A denotes the routing and Algo Boost bundle.
N3K-C3548P-FA-L3A supports serial-console CLI access, SSHv2, Telnet, SNMP, XML NETCONF and DCNM management. Administration can use in-band connectivity or the dedicated management interfaces. Specify the intended access method, authentication configuration and management-network connections when preparing the configuration and acceptance requirements for an order.
N3K-C3548P-FA-L3A reached end of sale on October 7, 2016, and Cisco support ended October 31, 2021. Its immediate replacement, N3K-C3548-X-SPL3A, is also discontinued. The replacement chain continues to N3K-C3548P-XL, so distinguish an original-generation replacement purchase from a migration to the current successor.
ORM Systems offers N3K-C3548P-FA-L3A new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Every condition has 30-day returns; terms apply. Cisco's original 1-year limited hardware warranty and service ended October 31, 2021.
N3K-C3548P-FA-L3A combines N3548-BAS1K9 Base, N3548-LAN1K9 LAN Enterprise and N3548-ALGK9 Algo Boost licensing. LAN Enterprise requires the Base license, while Algo Boost enables NAT, warp mode and warp SPAN. State the required entitlements explicitly on the order and verify them during configuration acceptance.
The Nexus 3548 supports SFP-10G-SR for multimode fiber, SFP-10G-LR for single-mode fiber and SFP-H10GB-CU3M for a 3 m direct-attach copper connection. Select the media against the complete link specification, including the remote interface, cable route and fiber type, rather than ordering optics by connector appearance alone.
N3K-C3548P-FA-L3A uses two N2200-PAC-400W AC supplies with port-side exhaust airflow and redundant operation. Input voltage is 100-240V AC. Include both supply positions in the receiving inspection, and specify the required power-cord arrangement against the site's electrical connections before releasing the purchase order.
The Nexus 3500 supports 24000 IPv4 unicast routes in normal mode and 4000 in warp mode. Separately, the Base license limits OSPFv2 to 256 routes; LAN Enterprise enables advanced routing. Check both the operating mode and license entitlement when comparing an existing configuration with the intended replacement.
No, N3K-C3548P-FA-L3A is a non-PoE switch with SFP+ network interfaces rather than powered RJ-45 access ports. The copper management connections serve administration, not endpoint power delivery. Keep endpoint power requirements separate from the optical switching specification when preparing the equipment list and reviewing proposed substitutions.
N3K-C3548P-FA-L3A enables 48 network ports, whereas N3K-C3524P-10G enables 24 ports on the same underlying hardware design. Both original-generation products are discontinued. The 48-port bundle suits an existing installation requiring the larger enabled interface count; the 24-port model represents the lower-density original configuration.
N3K-C3548P-FA-L3A uses AC input, while N3K-C3548P-FD-L3A uses DC input; both retain forward, port-side exhaust airflow. Both bundles are discontinued. For a controlled replacement, the AC version matches an AC-powered installation, while the DC version matches an installation already provisioned for DC input.
N3K-C3548P-XL has 16 GB of DRAM, compared with 4 GB in N3K-C3548P-FA-L3A. The XL model is the current endpoint of the replacement chain. The original bundle suits a controlled original-generation replacement; the XL model is the successor to specify when planning a forward migration.
