Introduction to n9000-epld.7.0.3.I7.3.img Software

This EPLD (Electrically Programmable Logic Device) firmware package provides critical hardware-level updates for Cisco Nexus 9000 series switches running NX-OS 7.0(3)I7(3). Designed to address field-programmable gate array optimizations, it enhances system stability and resolves hardware compatibility issues in data center deployments.

The firmware specifically targets components including line card PHYs, power supply controllers, and fan module interfaces. Compatible devices include Nexus 93180YC-EX, 9336PQ, and 9348GC-FXP platforms with Gen2/Gen3 hardware revisions.

Key Features and Improvements

Version 7.0.3.I7.3 delivers essential hardware optimizations:

  1. ​​Power Subsystem Stability​​

    • Resolves intermittent voltage regulation faults in 3kW AC power supplies
    • Improves PSU fan speed calibration algorithms

  2. ​​Thermal Management​​

    • Enhanced temperature sensor polling for N9K-X9736C-FX line cards
    • 25% reduction in false-positive overtemperature alerts

  3. ​​Forwarding Engine Reliability​​

    • Fixes CRC error counter overflow in 100G QSFP28 interfaces
    • Updates SerDes tuning parameters for improved signal integrity

  4. ​​Boot Process Enhancements​​

    • Reduces POST time by 18% on Nexus 9336PQ switches
    • Adds FPGA signature verification during hardware initialization

Compatibility and Requirements

Supported Hardware Minimum NX-OS Version Service Impact
Nexus 93180YC-EX 7.0(3)I7(1) Cold reload
Nexus 9336PQ 7.0(3)I7(2) Line card reset
Nexus 9348GC-FXP 7.0(3)I7(3) Full chassis reboot

​​Critical Notes​​:

  • Incompatible with mixed chassis configurations containing Gen1 line cards
  • Requires sequential installation when updating multiple hardware components

Introduction to nxos.CSCvx18710-n9k_ALL-1.0.0-7.0.3.I7.9.lib32_n9000.tar Software

This SMU (Software Maintenance Upgrade) package resolves critical bootflash reliability issues in Nexus 9000 series switches using Micron_M500IT SSDs. The hot-patch solution addresses CSCvx18710 – a hardware-level defect causing filesystem read-only failures after 28,224 operational hours.

Compatible with NX-OS 7.0(3)I7(x) releases, it provides non-disruptive firmware updates for switches in production environments. Supported platforms include Nexus 93108TC-EX, 9332PQ, and 9372PX-E chassis with dual supervisor modules.

Key Features and Improvements

The CSCvx18710 patch delivers essential storage enhancements:

  1. ​​SSD Longevity Fix​​

    • Overrides faulty Micron MU01.00 firmware power-on hours counter
    • Prevents buffer overflow in NAND controller logic

  2. ​​Operational Continuity​​

    • Enables in-service firmware updates without system reboot
    • Maintains 99.999% availability during patch activation

  3. ​​Diagnostic Improvements​​

    • Adds SMART attribute monitoring for SSD health prediction
    • Implements automatic filesystem check before firmware update

  4. ​​Compliance Updates​​

    • Aligns with NIST SP800-131A cryptographic standards
    • Enforces SHA-256 signed firmware validation

Compatibility and Requirements

Affected Hardware SSD Model Patch Method
N9K-C93108TC-EX Micron_M500IT 64GB ISSU
N9K-C9332PQ Micron_M500IT 128GB SMU Install
N9K-C9372PX-E Micron_M500IT 64GB Dual SUP Sync

​​Deployment Constraints​​:

  • Requires minimum 4GB free bootflash space
  • Incompatible with FIPS mode enabled systems

​​Secure Download Access​​
Both firmware packages are available through IOSHub.net with:

  • Cisco TAC-verified cryptographic signatures
  • Hardware compatibility validation tools
  • 24/7 enterprise support SLA

Always verify package integrity using SHA-512 checksums provided in Cisco’s Security Advisory portal. Maintain previous stable firmware versions on secondary storage for emergency rollback scenarios.

Note: The EPLD firmware requires physical presence verification for security compliance. The SSD patch must be installed before reaching 27,000 operational hours to prevent filesystem corruption.
