Configuring the AM-138
Page 15
Eagle 450 Upgrade Instructions, Rev. A00
Before installing the SSD chip in the AM-138, write the SSD number in a secure place for future
reference. Install the SSD at its clearly marked socket at U34 (see Figure 4-1), by inserting and pressing
down gently on the chip. Make sure you align pin-1 on the SSD chip with the SSD socket.
ON-BOARD SERIAL PORTS
The AM-138 contains eight on-board serial ports. These are standard, fully functional ports, to which
you can attach any supported terminal, printer, or modem. When you define these terminals, use the
A31810 interface driver, as described in Chapter 5. Port 0 is the system boot port.
You can also use the AM318.IDV interface driver for the on-board serial ports. However, since
this driver doesn’t support full modem control, we recommend the A31810.IDV driver.
In any upgrade, these ports can use either DB-9 connectors or AM-90 cards with RJ-45 connectors on the
back panel, depending on the internal cable kit ordered. The AM-90 card has the advantage of lightning
protection. The ports support full modem control with either cabling option, as long as they use the
A31810 interface driver.
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 450 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-00156-00.
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'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.
