Introduction to n9000-epld.10.3.5.M.img Software
The n9000-epld.10.3.5.M.img is a critical FPGA/EPLD update package for Cisco Nexus 9000 Series switches, designed to resolve hardware-level operational anomalies and enhance system reliability. Released as part of Cisco NX-OS 10.3(5)M maintenance train, this firmware targets power management and I/O subsystem optimizations for data center deployments.
Compatible with Nexus 9500/9300/9200 platforms, this update addresses 12 documented hardware errata while maintaining backward compatibility with NX-OS 10.2(x) configurations. The 10.3(5)M version specifically targets Field-Programmable Gate Array (FPGA) components in supervisor and line card modules.
Key Features and Improvements
1. Power Subsystem Enhancements
- Fixed voltage regulation errors in 9500-R Series line cards
- Improved thermal monitoring for 9300-GX chassis
- Resolved intermittent fan tray communication failures
2. I/O Stability Upgrades
- Patched CRC errors on 100G QSFP28 interfaces (CSCwd78932)
- Enhanced SerDes calibration for 400G-ZR optics
- Optimized buffer allocation for lossless RoCEv2 traffic
3. Security & Diagnostics
- Added SHA-512 signature verification for FPGA images
- Extended system health monitoring to cover redundant PSU paths
- Fixed false-positive CRC alerts in “show hardware internal errors”
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS Version |
|---|---|
| Nexus 9508/9516/9504 | 10.2(3)F |
