C A U T I O N :
TO REMOVE A CARD, FIRST TURN OFF THE POWER AT THE POWER SUPPLY UNIT(S).
HANDLE THE CARD BY THE PLASTIC FACEPLATE OR LEVERS ONLY. STATIC
DISCHARGE CAN DAMAGE THE CARDS.
ONCE REMOVED, CARDS SHOULD NOT BE SET ON A METAL SURFACE.
DO NOT TURN ON THE POWER UNTIL YOU ARE SURE ALL CARDS ARE FIRMLY
SEATED.
Service Technician Diagnostics
Diagnostics can be accessed only from station 10. All stations should be idle when the diagnostics
are run (no telephone calls in progress). Since the 48-button adjuncts place extra loading on
the system, all 48-button adjuncts MUST be disconnected from the system during controller self
test. This can be done by unplugging them at the adjunct or the controller. If calls are in
progress or an adjunct is plugged in, the tests will not run.
Controller Self Test
The Controller Self Test procedure may help you confirm that the controller, the expansion unit,
and the installed cards are working properly.
Plug a 24-button SPIRIT telephone directly into station jack 10.
Press INTERCOM.
Lift the receiver.
Dial
9 2448.
You should hear a confirmation tone. If you hear an error tone, hang up and start over (at
Press INTERCOM), having made sure that a 24-button telephone is plugged directly into
station jack 10. After hearing a confirmation tone, PLACE THE RECEIVER AWAY FROM
YOUR EAR.
Dial 9 #
If you hear either a busy or an error tone, hang up and start over (at Press INTERCOM),
having made sure that no one is using a telephone and that any 48-button Attendant Adjuncts
are unplugged.
After about 20 seconds, testing will be complete and the results will be shown on a block of 15
indicator lights on the telephone (see page 24).
If the indicator light is on, that portion of the test has passed.
If the indicator light is off, that portion of the test has failed.
If the indicator light is blinking, that slot on the controller should be empty, and if it is not
empty, the test has failed.
If the self test seems to run and the results are never displayed, the CPU has a fault. A
fault may lock up the system until the power is cycled.
