Eagle 250 Upgrade Instructions, Rev. A00
The mounting plate helps to stabilize the chassis. With it removed, You will be able to rock
the chassis back and forth slightly. This is normal.
6. Remove the AM-319 from the mounting plate by unscrewing the nine screws holding it in place.
7. If the computer contains an AM-219 floppy controller, remove it and the diskette drive. Only
SCSI diskette drives are supported with the Eagle 250.
PREPARING THE AM-138-10 BOARD
1. Use eight of the mounting screws you just removed to attach the AM-138-10 to the mounting
plate.
2. If you haven’t yet, check the jumpers on the AM-138-10 board to make sure they are set
correctly. Refer to the table in Chapter 4.
3. Install one or two memory SIMMs at J10 (and J11), following the instructions in Chapter 3.
4. If you haven’t already done so, remove the SSD from your old CPU board (see page 16) and
carefully install it into the AM-138-10 board at U34 (see Figure 4-1).
5. If you are going to install the AM-138-10 board into a “new style chassis”, as described on page
1, install the small rear sub-panel (DWF-20765-10), included in your upgrade kit, to the 9-pin
and 25-pin connectors at the rear edge of the AM-138-10 board using the male / female standoffs
from the old rear panel yet to be removed.
INSTALLING THE NEW REAR PANEL AND AM-138-10 (OLD STYLE
CHASSIS)
If you have the new style chassis, skip ahead to the next section.
1. Remove the four screws attaching the fan to the back panel and the back of the chassis. Save the
screws.
2. Remove the five screws attaching the rear panel to the chassis, as shown in Figure 7-6. Save
these screws, also.
3. The new rear panel is smaller, so the fan attaches directly to the back of the chassis. Use the same
four screws to reattach it in the same position it previously occupied.
4. Attach the new Eagle 250 rear panel to the back of the chassis using the five screws you just
removed. Leave the screws loose for now.
