Installing Plug-in PC Boards
WARNING
Remove power before inserting or removing the plug-in printed circuit
boards. Failure to adhere to this warning will result in equipment damage.
Insert each PC board into the card rack by aligning the edge of the board with the card rack guides and
pushing the card into the rack until the board’s front bezel is flush with the front of the card rack. Do not
force the card into the rack if the card is not aligned properly when pushed into the card rack. Move the
card slightly from side to side or up and down until the rear connector is aligned, and then press the card
until it is properly seated. Tighten the screws on the top and bottom of each board’s front bezel to secure
the board in the card rack. Each board must be installed into the proper card slot as shown in Figure 2.
The following printed circuit boards are included:
Master Control Unit (MCU)—Contains the central processing that coordinates all operations as defined
by its software configuration file. The MCU maintains communication with all other cards in the card
rack and with SmartSeries devices located throughout the system. See the MCU card’s publication for
additional information on the MCU’s operation and capabilities. A list of publications is found in the
Reference Material Section.

card supports up to 200 SmartSeries stations and an unlimited number Page/Party
®
stations. See the
Reference Material Section for additional information on the operation and capabilities of the PPI card.
Access Panel Interface (API)—Interfaces the access panels to the system. The API card supports up to

cord is provided with the card rack. Plug one end of the cord into the mating receptacle on the side of the
card rack and plug the other end into a standard 15A power receptacle.
