A4 Processor Board Assembly Troubleshooting
A4 Processor Board Assembly Troubleshooting
The A4 Processor board assembly is serviced as an assembly only; no
component level repair is supported, other than the A4A1 Disk Drive Interface
board.
Boot-Up or Initialization Problems
Typical failures of the A4 Processor board assembly will cause the instrument
to not boot-up or initialize properly. Of course, these types of failures can also
be caused by a variety of other assemblies as well. In order to determine
whether a problem such as this is being caused by a defective A4 Processor
board assembly, first see the “MXE Instrument Boot Up Process” on page 39
to eliminate other possibilities.
BIOS Settings
As with other types of PC processor board assemblies the A4 Processor board
assembly has a number of settings particular to the hardware on the board.
These settings are saved in a separate memory location on the board and
accessed by the BIOS (Basic Input Output System) Setup Utility. If these
settings are changed from those that the instrument was initially shipped with
this could cause a problem with the booting and/or functionality of the
instrument.
If the instrument is having a problem booting up, but is functional enough to
enter the BIOS Setup Utility you will want to verify that the BIOS settings have
not been changed.
Accessing BIOS Setup Utility
To easily navigate the BIOS Setup Utility you will want to have an external USB
keyboard connected to the instrument. Then, when the initial Keysight
Technologies splash screen is displayed at power-up, press the key on the
keyboard specified on the initial boot screen (typically the DEL key). Once this
is pressed you will see the main BIOS Setup Utility screen.
Load Defaults
Load the BIOS default values by navigating to the Exit screen and select
Restore Defaults or Load Setup Defaults, whichever is present. Once the
defaults have been loaded select Save Changes and Exit.
