Grass Valley K2 Summit 3G v.8.0 - Manual (Page 39)

System beep codes
When you start up the K2 Summit system by pressing the standby switch or by doing a Windows
operating system restart, the CPU module might emit two short beeps. Otherwise, if there are no
errors present, the K2 Summit system does not emit any audible beeps.
When an error occurs during Power On Self Test (POST), the BIOS displays a POST code that
describes the problem. The BIOS might also issue one or more beeps to signal the problem. This
indicates a serious error and it is likely that the carrier module must be replaced. Contact Grass
Valley Support.
