Audio beep sequences
The NetVista thin client hardware utilizes both audio and visual alerts when
reporting hardware problems. In the event of a hardware problem, the NetVista
thin client emits audio beeps before your monitor initializes. After your monitor
initializes, error codes and text messages appear on the screen.
Note:
The N70 BIOS Configuration/Setup Utility Program is defaulted to come up
quiet (no beep and no memory count and checkpoint code display) when no
errors are detected by POST.
To enable beep and memory count and checkpoint code display when a
successful POST occurs:
v
Select Start Options in the Configuration/Setup Utility program (see
“Appendix C. Using the BIOS Configuration/Setup Utility program” on
page 43).
v
Set Power-On Self-Test to Enhanced.
Audio beep sequences are constant, but the length of the pause between the beeps
varies. Table 4 on page 24 defines the possible audio beep sequences that can occur
when a hardware problem exists.
To verify that a NetVista thin client hardware problem exists, ensure that you
complete the instructions in “Verifying hardware problems” on page 19.
If the NetVista thin client is not functioning properly, and it is emitting audio beep
sequences, consult Table 4 on page 24. Contact your technical support if these steps
do not resolve the problem.
Notes:
1.
These beep sequences are in a numeric format which indicates the sequence of
the audio output.
2.
Audio beep sequences do not occur after the monitor initializes.
