Frequently asked questions

Why does my R440 reboot when the UPS switches to battery power?

The reboot may be due to the UPS outputting a simulated sine wave, which can cause the R440's power supply to lose sync and restart. Ensure the UPS provides a pure sine wave output and has a transfer time of less than 4 ms. Additionally, check for firmware updates for both the UPS and the R440. [community thread]

Why does my server shut down after losing one power supply when it shouldn't?

The unexpected shutdown may be due to outdated firmware or misconfigured settings. Ensure that all firmware, including BIOS and iDRAC, is updated to the latest version, and verify your power management settings. Running hardware diagnostics can also help identify any underlying issues. [community thread]
