2-Beep Test (Server Boot Indicator)

A diagnostic signal produced during server startup, indicating the motherboard has successfully completed memory checks and initialization.

When a server starts, it runs a quick internal check to confirm that key components like the CPU, memory, and motherboard are working properly. Some systems give two short beeps to signal success before the operating system loads. The exact pattern depends on the motherboard or BIOS brand, so check the manual for details. If you hear no beeps, continuous ones, or something unusual, it usually means a hardware issue needs attention. The beeps are the server’s first way of telling you how healthy it is.
