Introduction to n7000-s1-epld.6.2.24.img

This EPLD (Electrically Programmable Logic Device) firmware package addresses hardware-level compatibility for Cisco Nexus 7000 Series switches with Supervisor 1 modules. Designed to resolve FPGA synchronization issues during chassis component upgrades, version 6.2.24 ensures proper communication between line cards and control processors in mixed-hardware environments.

Compatible platforms include:

  • Nexus 7010/7018 chassis with M1/M1-XL line cards
  • Nexus 7009 fabric modules
  • Supervisor 1 modules (N77-SUP1, N7K-SUP1)

Key Features and Improvements

  1. ​​Fabric Module Synchronization​​
    Resolves CRC errors during data plane operations between Gen1 and Gen2 fabric modules.

  2. ​​Power Management Enhancements​​
    Updates voltage regulation algorithms for N7K-AC-3KW power supplies to prevent unexpected reboots.

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

  4. ​​Security Validation​​
    Implements SHA-256 verification for firmware integrity checks during boot sequences.

Compatibility and Requirements

Component Minimum NX-OS Version Supported Hardware
Supervisor 1 6.2(12) N7K-SUP1
M1 Series Line Cards 6.2(8) N7K-M148GS-11L
Fabric Modules Fabric-1 N7K-C7010-FAB-1

​​Critical Note​​: Requires sequential upgrade of redundant supervisors when used in VDC configurations.
