The Microsoft® Exchange Server Analyzer Tool queries the Win32_BIOS Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the SMBIOSBIOSVersion key. The value returned represents the version number of the BIOS installed on the computer. The Exchange Server Analyzer also examines the Win32_ComputerSystem WMI class to determine the value of the Model key.

If the Exchange Server Analyzer finds that the Model key contains any of the following strings, and the SMBIOSBIOSVersion is not the latest version for the model, a warning is displayed:

  • PowerEdge 2400

  • PowerEdge 2450

  • PowerEdge 2500

  • PowerEdge 2600

  • PowerEdge 2650
