Check all green lights on the fronts of the modules.
If all lights are lit, you can go to the next section;
otherwise:
A) If a single light is out, power down the control
unit, reseat the module, then power up the
control unit.
If multiple lights are out, power down the
control unit, reseat the leftmost module that
has a light out, then power up the control unit.
B) If the lights are still out, call for support as
instructed on the inside front cover.

Test for dial tone at the network interface jacks
before connecting outside lines to the control
unit. For the test, connect a standard phone
to the first network interface jack.
Lift the handset and listen for dial tone. (If there
is no dial tone, contact your local telephone
company before continuing.)
Repeat for each network interface jack.
Connect line cords to the line jacks on 206 and
400 modules, starting with the top line jack on
the leftmost 206 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 line cord to the
