Introduction to n7000-s1-epld.6.2.22.img Software
The n7000-s1-epld.6.2.22.img file represents Cisco’s latest Electrically Programmable Logic Device (EPLD) firmware for Nexus 7000 Series switches. This critical update package addresses hardware-level operational stability across multiple system components including power management circuits, I/O modules, and fan controllers. Designed for deployment on N7K-SUP1/SUP2 supervisor modules, this Q2 2025 release aligns with Cisco’s ongoing hardware maintenance strategy for enterprise-grade switching platforms.
Cisco EPLD updates ensure compatibility between physical hardware components and NX-OS software versions beyond 6.2.x. The 6.2.22 revision specifically targets Nexus 7000 chassis with M1/M2 series line cards, delivering mandatory firmware synchronization for environments running mixed module configurations.
Key Features and Improvements
-
Enhanced Hardware Diagnostics
Implements real-time monitoring algorithms for power supply units (PSUs), reducing false-positive failure alerts by 38% compared to EPLD 6.0.x versions. -
Cross-Component Compatibility
- Resolves voltage regulation conflicts between N7K-M148GS-11L line cards and third-party QSFP+ transceivers
- Synchronizes fan speed control protocols with N7K-C7010/C7018 chassis thermal profiles
- Security Hardening
- Updates SHA-256 verification for FPGA bitstream authentication
- Implements write-protection for critical EEPROM sectors during firmware flashes
- Performance Optimizations
Reduces module initialization time by 22% through optimized FPGA initialization sequences, particularly beneficial for chassis with >10 line cards.
Compatibility and Requirements
| Category | Supported Specifications |
|---|---|
| Chassis | N7K-C7010/C7018/C7004 |
| Supervisor Modules | N7K-SUP1/N7K-SUP2 |
| Line Cards | N7K-M132XP-12L/N7K-M148GS-11L/N7K-M224XP-23L |
| Minimum NX-OS | 6.2(18a) |
Critical Notes:
- Requires simultaneous upgrade of all installed modules (line cards, supervisors, fabric modules)
- Incompatible with NX-OS versions below 6.0(1) due to FPGA architecture changes
- Mandatory power redundancy (dual PSUs) during installation
