Introduction to n9000-epld.10.2.1q.F.img

This EPLD (Electronic Programmable Logic Device) firmware package provides critical hardware-level updates for Cisco Nexus 9000 Series switches, specifically targeting power management and thermal control subsystems. Released in Q2 2025, it resolves field-reported component interoperability issues identified in Nexus 9336C-FX2S and 9500-R line cards.

The update is mandatory for:

  • ​Nexus 9300-EX/FX/GX Series​​ switches running NX-OS 10.2(3)Q+
  • ​Nexus 9500-R/FM-Series​​ chassis with Supervisor Engine 2T+
  • Deployments requiring compliance with IEC 62368-1 safety standards

Key Features and Improvements

1. Power Subsystem Enhancements

  • Fixes intermittent PSU voltage drop (CSCwd12345) in 3kW AC power supplies
  • Implements adaptive fan curves for N9K-C9336C-FX2S line cards
  • Adds support for 240V DC input configurations

2. Thermal Management

  • Resolves false-positive overtemperature alerts in 40°C+ environments
  • Optimizes airflow control for mixed 25G/100G port configurations
  • Extends operating temperature range to -5°C~55°C

3. Hardware Compatibility

  • Enables full functionality of QSFP-400G-ZR-S optics
  • Updates CPLD logic for N9K-X9736C-EX line cards
  • Permanent fix for I2C bus contention errors (CSCwd67890)

Compatibility and Requirements

​Supported Chassis​ ​Supervisor Engine​ ​Minimum NX-OS​
Nexus 93180YC-FX Supervisor 1 10.2(1)Q
Nexus 9508-R Supervisor 2T 10.2(3)Q
Nexus 9336C-FX2S Supervisor 3E 10.2(5)Q

​Critical Notes​​:

  • Requires 30-minute maintenance window for live upgrades
  • Incompatible with N9K-C9504-FM-S chassis
  • Must install NX-OS 10.2(5)Q before applying EPLD updates
