Power Connection
Each option module derives power from the base TSU/TDU unit.
Power to the TSU/TDU is supplied by a captive eight-foot power
cord.
Attaching the Plug-On Board
Figure 2-2 shows the proper attachment of a plug-on board to the op-
tion module. Perform the following steps to install the plug-on
board:
1. Hold the plug-on board above the option module.
2. Using a downward and right-to-left motion, slip the V.35 Con-
nector plug into opening in the option module back panel.
3. Moving the plug-on board downward, secure the connection of
the header pins at the front of the boards.
4. Install the two 4-40 screws at both edges of the option module.
Figure 2-2.
The connection of the header pins between the option module
and the plug-on board must be visually verified. Severe dam-
age of the equipment can result from an improper connection.
