2 Check all green lights on the
fronts of the modules. If all the
lights are lit, continue with

. If any lights are
out, do the following:

If a single light is out,
power
down the control unit, reseat
the module, then power up
the control unit.
b.
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.
c.
If the lights are still out,
call
for support as instructed on
the inside front cover of this
guide.
Connecting Lines and Extensions
If extensions are not wired to any modular jacks, call a qualified service
technician.
Use the following procedure to connect lines and extensions:
1 a. Test for a 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.
b. Lift the handset and listen
for a dial tone. (If there is no
dial tone, contact your local
telephone company before
continuing.)
c. Repeat for each network
interface jack.
