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
