Last Modified: Oct 23, 2025

Affected Product(s):
F5OS All(all modules)

Known Affected Versions:
F5OS-A 1.5.0, F5OS-A 1.5.1, F5OS-A 1.5.2, F5OS-A 1.5.3, F5OS-A 1.5.4

Opened: Apr 30, 2024

Severity: 2-Critical

Symptoms

iSeries and rSeries systems using the PWR-0306-xx 650W power supply can exhibit false errors that can cause system reboots or alarms. Murata Power implemented a new firmware version to improve the robustness of the UART communications on the PWR-0306-08 power supply to mitigate this issue.

Impact

End users may experience system reboots or power supply status warnings/alarms.

Conditions

650W power supplies with a dash roll number of -07 or older have about a 1% chance of exhibiting the false errors.

Workaround

If there is a field failure with this issue the recommendation is that the power supply be replaced with a PWR-0306-08 or newer revision.

Fix Information

None
