Test the lines—plug a system phone into extension
jack 10. Press the line buttons for each
outside line and listen for dial tone.
Repeat for extensions 16, 22, 28, 34, 40, and 52
(if available).
Connect modular telephone cords to 206 module
extension jacks, starting at the top extension
jack on the leftmost module.
Route each cord through the hook on the front of
the module, then push the cords through the
space below the module and out through the
back.
Pull the cords from behind the backplane,
leaving at least two feet (0.6 meters) of slack
in the cords (for future maintenance, so you
can easily reconnect cords after replacing
system modules).
Connect the free end of each modular telephone
cord to the modular connecting blocks for
system extensions.
Place the cover on the control unit—this is
especially important to keep the modules
dust-free and the system working efficiently.
To cover the control unit, while holding the
cover at an angle, gently move the top rear
edge of the cover over the top of the control
unit.
Match up the grooves where the top edge of the
cover meets the backplane, and gently push
the edge into place.
Lower the bottom of the cover until it is secured
in place.
