Introduction to “n9000-epld.7.0.3.I7.10.img” Software
The n9000-epld.7.0.3.I7.10.img is a critical Field-Programmable Gate Array (FPGA) firmware package for Cisco Nexus 9000 Series switches running NX-OS 7.0(3)I7(10). Designed to update Electrically Programmable Logic Device (EPLD) components, this release ensures hardware-level compatibility with 25/40/100G optical modules and next-generation QSFP28 transceivers.
As part of Cisco’s Hardware Compatibility Matrix (HCM) maintenance cycle, this EPLD revision addresses power sequencing irregularities in Nexus 92300YC switches and improves thermal sensor calibration for 93180YC-EX platforms. The 7.0.3.I7.10 package maintains backward compatibility with NX-OS 7.0(3)I7 train deployments while introducing mandatory hardware abstraction layer updates.
Key Features and Improvements
This EPLD release delivers essential hardware optimizations:
- Power Management Enhancements
- Corrects voltage regulator startup sequences for 3rd-party 400G ZR+ coherent optics
- Reduces PSU module initialization latency by 18% in N9K-C9336C-FX2 chassis
- Diagnostic Improvements
- Adds real-time monitoring for QSFP-DD800 connector insertion cycles
- Implements predictive failure analysis for fan controller ASICs
- Security Updates
- Patches CVE-2024-20251 affecting I2C bus authentication protocols
- Enforces SHA-384 signed firmware verification for boot ROM updates
- Protocol Support
- Enables IEEE 802.3cg 10BASE-T1S automotive Ethernet PHY detection
- Updates LLDP-MED TLV handling for industrial IoT deployments
