Why are NEC Server VDs configured for write-back running in write-through mode?
- S
  Shannon GloverAug 27, 2025
  If your NEC Server's VDs configured for write-back are temporarily running in write-through mode, it's likely due to the battery charging, being missing, or being faulty. Run WebBIOS or Universal RAID Utility to check if battery for RAID Controller is detected. If the battery is not detected, check the connection and allow it to charge for at least 24 hours. If the battery is detected, halt the system for at least 9 hours to charge the battery. If the problem persists, contact your service representative.

  hamiltondeannaAug 26, 2025
  If your NEC Server won't power on, start by checking the power cord connection to both the server and the power outlet or UPS. Ensure the power cord meets the Blade Enclosure power specifications and isn't damaged. Verify that the connected power outlet's circuit breaker is on. If using a UPS, confirm it's powered and functioning correctly. Also, ensure the CPU blade is correctly installed, and if a mezzanine card is installed, check the connection between the relevant switch module and the CPU blade. After applying AC power (POWER LED lights amber), wait at least 60 seconds before turning on the Blade Enclosure.
