PRO3X 4.3.13 General Availability (GA) Firmware Release
General Availability (GA) releases are fully tested, production-ready, and are recommended for most customers and deployments.
Limited Availability (LA) releases are of the same testing and production quality as GA releases but may have some missing or extra features. Because of this, LA releases are typically only delivered to select customers and/or select product types. Related binary files are, therefore, not available for public download through the website. For access to LA binary files, please contact your regional Server Technology Support team for assistance who will first ensure proper compatibility with your specific model(s) and then will provide files as needed.
Important note for customers using PRO3X & PRO4X PDU models with Xerus™ platform:
We have identified a critical issue in the PDU firmware version 4.0.0 and later. Due to features introduced in 4.0.0 and later firmware, the flash write frequency on ServerTech PRO3X and PRO4X PDUs with Xerus controllers may cause flash wear, leading to long-term reliability and performance issues. This does NOT affect the PDU outlet power state. An upgrade to Xerus Firmware v4.3.13 or later is required to reduce flash write cycles and mitigate this potential issue. Please prioritize this firmware upgrade in your operations.
