Introduction to n9000-epld.9.2.3.img

This FPGA/EPLD firmware package addresses hardware-level compatibility for Cisco Nexus 9000 Series switches operating in ACI/NX-OS modes. Designed to resolve field-programmable gate array mismatches during system upgrades, version 9.2.3 ensures proper synchronization between embedded controllers and modular components like line cards and supervisor engines.

Compatible platforms include:

  • Nexus 9500 chassis with N9K-X9636C-R/EX line cards
  • Nexus 9300-FX2/FX3 series fixed switches
  • Nexus 9800 Cloud Scale Fabric Modules

Key Features and Improvements

  1. ​​Optical Interface Validation​​
    Resolves SFP/XFP module recognition failures caused by FPGA version mismatches during ACI conversions.

  2. ​​Power Subsystem Enhancements​​
    Updates voltage regulation algorithms for N9K-PUV2 power supplies to prevent unexpected shutdowns.

  3. ​​Security Hardening​​
    Implements SHA-256 verification for firmware integrity checks during boot sequences.

  4. ​​Diagnostic Improvements​​
    Adds CLI command show hardware epld-versions for real-time FPGA status monitoring.

Compatibility and Requirements

Switch Model Minimum NX-OS Version Supervisor Compatibility
Nexus 9508 9.3(5) SUP-A/B/C
Nexus 93180YC 9.3(3) Built-in
Nexus 9336C 9.2(4) SUP-C/D

​​Critical Note​​: Requires simultaneous upgrade of chassis components when used with mixed-version line cards.
