CISCO N3K-C3548P-10GX Nexus 3000 Series Switches

N3K-C3548P-10GX Hardware Identity

N3K-C3548P-10GX identifies the Cisco Nexus 3548-X, a fixed 1-RU low-latency data-center switch in the Nexus 3500-X. Cisco documents 48 fixed 10 Gigabit Ethernet SFP+ ports. Optional modules, optics, cables, licenses and support are included only when explicitly itemized.

Forty-eight-port latency baseline

Assign each SFP+ interface to a compute, storage, market-data or inter-switch role and record the transceiver, fiber, peer and latency requirement. A low-latency platform should be accepted with the intended packet sizes and traffic pattern, not a generic throughput test. Preserve the NX-OS image checksum and the feature set that was active during measurement. Because this is the X rather than XL identity, memory and software assumptions must come from the exact received chassis, while migration planning should price the cost of preserving specialized optics and cabling.

Acceptance test

Measure latency and loss across representative port pairs, remove one port-channel member, verify optical diagnostics and retain the lifecycle exception.

Lifecycle boundary

The 3548-X generation is covered by Cisco lifecycle guidance; verify current support and compare migration to the 3548-XL or a supported successor.

Receiving controls

• Match the exact PID, serial, installed modules, airflow and power configuration.
• Record every port personality, optic, cable, breakout and peer relationship.
• Confirm NX-OS or ACI mode, image checksum, license and controller compatibility.
• Attach failure-test evidence and a dated migration decision to the asset record.
