A peripheral is installed in the drive mounting bracket using four Phillips-head screws. To install the
peripheral mounting screws, you need access to both sides of the peripheral mounting bracket. On one
side of the cabinet, all six of the mounting positions are easily accessible. However, on the other side of
the cabinet, the AM-319-20 board and its mounting bracket block access to all but the top two mounting
positions. To ease the installation process, Alpha Micro installs peripherals starting at the top position
and working down. If your computer includes one disk drive and one tape drive, the two peripherals will
be mounted in positions 1 and 2, which are easily accessible from both sides of the chassis.
To install peripherals in mounting positions 3, 4, 5, and 6, you will need to remove the AM-319-20 board
and its mounting bracket from the chassis. At first glance, this might seem difficult, but if you follow the
procedure outlined below, it will make the task much easier.
1.
Remove the three Phillips head screws where indicated in Figure 12. The three screws hold the
AM-319-20 I/O mounting bracket to the chassis rear panel.
2.
Remove the threaded hex nut, as shown in Figure 12, to provide enough clearance to lift the
AM-319-20 board up and out of the chassis bottom pan.
