N5K-C56128P - Cisco Nexus 5000 Series Switch

N5K-C56128P Hardware Identity

N5K-C56128P identifies the Cisco Nexus 56128P, a fixed 2-RU switch with two expansion slots in the Nexus 5600 expandable platform. Cisco documents 48 fixed 1/10G SFP+ ports, 4 fixed 40G QSFP+ ports and 2 expansion slots. Optional modules, optics, cables, licenses and support are included only when explicitly itemized.

Expansion-slot bill of materials

A base N5K-C56128P does not define the two expansion slots. Record each installed module PID, serial, port personality, optics and entitlement, and identify any empty slot. Build the capacity model from the actual forty-eight fixed SFP+ and four fixed QSFP+ interfaces plus verified modules, not a maximum configuration. If Fabric Extenders are attached, include every FEX, host interface and parent uplink in the replacement plan. The cutover must distinguish fixed ports from expansion-module ports so a module omission cannot strand storage or server links.

Acceptance test

Inventory both expansion bays, test representative fixed and module ports, validate one FEX path if present, and preserve the exact converged-network configuration.

Lifecycle boundary

Confirm the installed expansion modules, NX-OS support, Fabric Extender dependencies and the current migration architecture.

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.
