Table 4-2 Hardware installation problems
Problem Probable Cause Recommended Solution
A new device is not
recognized as part of
the system.
Device is not seated or
connected properly.
Ensure that the device is properly and securely connected and that pins
in the connector are not bent down.
Cables of new external
device are loose or power
cables are unplugged.
Power switch of new
external device is not turned
on.
Turn off the workstation, turn on the external device, then turn on the
workstation to integrate the device with the workstation system.
When the system advised
you of changes to the
configuration, you did not
accept them.
Reboot the workstation, and follow the instructions for accepting the
changes.
A plug and play board might
not automatically configure
when added if the default
configuration conflicts with
other devices.
Use Computer Setup (F10) to reconfigure or disable devices to resolve
the resource conflict.
Workstation will not start. Wrong memory modules
were used in the upgrade or
memory modules were
installed in the wrong
location.
1. Review the documentation that came with the system to determine
if you are using the correct memory modules and to verify the proper
installation.
2. If you still cannot resolve the issue, contact Customer Support.
3. Observe the beeps and LED lights on the front of the workstation.
See
Diagnostic lights and audible (beep) codes on page 28 to
determine possible causes.
Workstation will not shut
down.
Proper steps were not
followed.
1. Shut down the operating system software.
2. Manually turn off power to the workstation by pressing and holding
the power button for four seconds.
CAUTION: Manually turning off the power bypasses the standby
state and can result in loss of data.
3. To reconfigure the power button to work in On/Off mode, run
Computer Setup (F10).
For more information about using Computer Setup, refer to the Service
and Technical Reference Guide, which is available through a link on the
Documentation and Diagnostics CD (
