Figure 5: AM-138 Backup Battery Removal
4.
Inspect the battery contacts and be sure they are clean before installing the new batteries. Use
alcohol and a cotton swab to clean them, if necessary.
5.
To install a new battery, insert the edge of the battery down through the square hole and under
the left side of the plastic top. Be sure to install the new batteries with the (+) positive side up.
6.
Use your finger to slide the battery to the left and down, until the right edge of the battery slips
under the right side of the plastic top. Release the battery and it should spring to the right,
securing itself under the holder's top piece.
Restoring Your CMOS Settings
The AM-138’s batteries also maintain the boot routine data stored in its CMOS chip. Therefore, when
you replace the batteries, your CMOS settings will be lost. After you install the new batteries and turn
system power on, you need to access the CMOS Configuration menu and restore your settings. Refer to
the Eagle 250 Installation and Technical Manual for detailed instructions.
If you do not use the CMOS configuration menu to restore your settings, the system will drop into a
standard default boot routine: it will look first for a warm-boot streamer tape on SCSI device ID 3, then
for AMOS32.MON and AMOS32.INI on SCSI disk drive 0.
Once the system is up and running, log to OPR: and enter the current time and date. Reboot the system to
initialize the system up time.
SSD and PROM Chip Removal
The type of socket used for the boot PROM and SSD chips in your Eagle 250 requires a special tool for
chip removal. If you ever need to remove and replace either of these chips, be sure to use the correct tool,
as shown in Figure 6.
