Disassembly and Installation for MPD-3 Units with SID Displays
In some older installations, a screw and two nuts were installed under the Card Cage on Side B
of a unit. This causes the installed Card Cage to rest at an angle, higher on Side B. This
hardware must remain in place to prevent contact between the Card Cage and the SID boards
when the bezel door is closed.
Disassembly and Installation for All MPD-3 Units
In field retrofits, the TRIND units top (center) screw from the Card Cage was removed, and
replaced by tie-wraps at either side after the Card Cage was installed in the cabinet. The Card
Cage can only be removed or installed when separated into two pieces (see Figure 4-5).
