FRONT PANEL STATUS DISPLAY CODES
Your computer includes a two-digit front-panel status display, which can show various codes indicating
the state of the system. Some of these codes will occur only while the computer is booting; others may
occur any time the computer is running. If you have a problem with your computer, check the front
panel; if there is a code displayed, look it up in the table in the Eagle 250 Installation and Technical
Manual to help diagnose the problem.
A separate set of codes appears on the front panel during the system self-test. Those codes are
listed in the System Self-test User’s Guide, DSO-00157-00.
SERIAL UPS MONITORING
With an Alpha Micro UPS (Uninterruptible Power Source) and the related UPS Monitoring Software
(Version 1.3(176) or later) installed, you can monitor the UPS from any terminal on the system. If any
problem arises, you can check the front panel status code, as described in the previous section.
You can find information about the configuration and use of the UPS monitoring software in the UPS
Monitor Software User's Guide, DSS-10394-00.
If you are using the AM-138-10's write buffering feature described in Appendix B, the system
monitor has a feature you should be aware of. To help prevent possible data loss, the write buffer
will be flushed and disabled if a low battery condition is detected by the system monitor via the
on-board UPS status port. However, this feature is not available when the Level 7 software is
actively loaded in the system initialization file.
