Diagnostic error message tables
For descriptions of the error messages that might appear when you run the diagnostic
programs, see “Diagnostic error codes” on page 220. If diagnostic error messages
appear that are not listed in those tables, make sure that the server has the latest levels
of BIOS, Advanced System Management Processor, ServeRAID, and diagnostics
microcode installed.
Light path diagnostics
The server has LEDs to help you identify problems with some server components.
These LEDs are part of the light path diagnostics built into the server. By following
the path of lights you can quickly identify the type of system error that occurred.
Power supply LEDs
The AC and DC power LEDs on the power supply provide status information about
the power supply. See “Installing a hot-swap power supply” on page 76 for the
location of these LEDs. See “Power checkout” on page 31 for more information on
power problems.
