Abstract

Potential Loss of Data can occur on an unexpected power outage

Description

We are enhancing our detection of Backup Power Modules (BPMs) with insufficient charge capacity to prevent potential data loss during a power outage. To strengthen this protection, we are introducing an improved BPM run‑time test algorithm designed to more reliably identify BPMs that cannot sustain the required charge. These updates ensure we proactively safeguard data by addressing insufficient BPM charge conditions before they become a risk.  This is a BPM age related issue and older systems are more exposed.   

Recommended Action

Systems over 48 months old MUST plan to update code.

Fix:
R9.4SP4.3 - 89.44.25.0

R9.4SP4.3 89.44.25.0
