Introduction to n7000-s1-epld.6.2.24.img Software

The ​​n7000-s1-epld.6.2.24.img​​ provides essential field-programmable gate array (FPGA) updates for Cisco Nexus 7000 Series switches with Supervisor 1 modules. This EPLD package resolves hardware-level packet forwarding anomalies and enhances ASIC temperature management algorithms for improved fabric stability.

Compatible with N7K-C7010/7018 chassis configurations, the firmware supports critical hardware components including N7K-F312FQ-25 line cards and N7K-SUP1 supervisor modules. Cisco’s technical bulletin confirms mandatory installation prior to NX-OS 7.3(5)+ upgrades to ensure proper hardware functionality.

Key Features and Improvements

Version 6.2(24) delivers critical hardware optimizations:

  1. ​​Thermal Management​​ – Dynamic fan speed adjustments reduce component stress in high-temperature environments by 18%
  2. ​​Packet Processing​​ – Resolves microburst-induced buffer overflows on 40G interfaces through revised queuing algorithms
  3. ​​Diagnostic Enhancements​​ – Adds 12 new POST error codes for power supply and I2C bus diagnostics
  4. ​​Security Validation​​ – Implements FPGA-side verification of digitally signed firmware images
  5. ​​LED Synchronization​​ – Improves status indicator patterns for real-time hardware monitoring

This release specifically addresses rare CRC error accumulation observed in N7K-M132XP-12 modules during sustained 40G traffic loads.

Compatibility and Requirements

Hardware Component Supported Models Minimum NX-OS Version
Supervisor Module N7K-SUP1 7.3(0)D1(1)
Line Card N7K-F312FQ-25 7.2(2)D1(1)
Chassis N7K-C7018 6.2(20)+

​​Implementation Notes​​:

  • Requires 512MB free bootflash space for installation
  • Incompatible with second-generation M3-series modules
  • Mandatory chassis power cycle after installation

Introduction to n7000-s2-kickstart.7.3.2.D1.3.bin Software

The ​​n7000-s2-kickstart.7.3.2.D1.3.bin​​ serves as the foundational bootloader for Cisco Nexus 7000 Series switches with Supervisor 2 modules, translating CLI commands into Linux kernel instructions. This kickstart image must be paired with matching system software (n7000-s2-dk9.7.3.2.D1.3.bin) for stable NX-OS operation.

Validated for N7K-C7018 chassis configurations, this release supports advanced features including VXLAN EVPN and FCoE optimization. Cisco’s release notes mandate its use with NX-OS 7.3(2)D1(3) for full hardware compatibility.

Key Features and Improvements

Version 7.3(2)D1(3) introduces:

  1. ​​Boot Optimization​​ – Reduces system startup time by 22% through improved kernel initialization sequences
  2. ​​Protocol Translation​​ – Enhances CLI-to-Linux command conversion efficiency for 64-bit NX-OS operations
  3. ​​Security Hardening​​ – Implements Secure Boot validation for kernel modules
  4. ​​Memory Management​​ – Resolves rare memory leaks during ISSU upgrades
  5. ​​Diagnostic Tools​​ – Adds 8 new debug commands for boot sequence troubleshooting

The update specifically addresses intermittent boot failures observed when using 40G QSFP+ transceivers in N7K-F348XP-25 modules.

Compatibility and Requirements

Component Supported Versions Memory Requirement
Supervisor Module N7K-SUP2 16GB DRAM
System Image 7.3(2)D1(3) 32GB Bootflash
Chassis N7K-C7010/7018 BIOS 3.14+

​​Critical Notes​​:

  • Requires simultaneous upgrade with matching system image
  • Incompatible with first-generation F1-series line cards
  • Mandatory SNMPv3 encryption for remote boot monitoring

Service Access and Download

The ​​n7000-s2-kickstart.7.3.2.D1.3.bin​​ package is distributed via https://www.ioshub.net featuring:

  • Version synchronization validators
  • Pre-upgrade configuration audit tools
  • Cisco-signed MD5 checksum verification
