Introduction to n9000-epld.7.0.3.I7.3.img Software
The n9000-epld.7.0.3.I7.3.img is a critical EPLD (Electrically Programmable Logic Device) firmware package for Cisco Nexus 9000 Series switches, designed to optimize hardware functionality and resolve field-programmable gate array-related operational issues. This release specifically targets power management subsystems and I/O controller stability in 40/100G QSFP28 modules.
Compatible with Nexus 93180YC-FX, 93240YC-FX2, and 9336C-FX2 platforms, the firmware addresses 14 CVEs identified in previous EPLD versions while maintaining backward compatibility with NX-OS 7.0(3)I7 base configurations. Cisco’s technical advisories confirm this build was validated for enterprise data center deployments in Q4 2024.
Key Features and Improvements
- Hardware Stability Enhancements
- Resolves intermittent power supply synchronization faults in N9K-PUV2 modules
- Fixes SFP+ port initialization failures caused by FPGA version mismatches
- Security Upgrades
