Wiring
Refer to the installation check out procedure for instructions for
testing the system wiring for possible failure.System Status Indicator
The power supply contains five red LED indicators.When these LEDs
are on,they indicate that their corresponding power supply voltages
are operational.
A red LED located on the commom equipment cabinet near the
cassette/music port is the system status indicator.This indicator is
turned on steady when power isapplied to the system.
If the
indicator flashes after power up,it could be indicating a processor
failure.Unplug and reconnect the AC powerto the power supply and
observe the LED indication.If it still shows a flashing indication,
refer to Figure 4-2.

. Station Self Test
The multiline stations can be self tested for proper operation per the
following instructions.
1.Disconnect the line cord at the station base.
IMPORTANT NOTE THE ADJACENT ODD OR EVEN STATION WILL BE DISABLED
DURING THE TIME THAT THE STATION LINE CORD IS BEING DISCONNECTED OR
RECONNECTED.
2.Press and hold theMUTEkey,and reconnect the.line cord to the
station connector.
The station will automatically perform a self test
routine.Release theMUTE key as soon as the test begins.
The
sequence of the test is as follows:

DSS/BLF Console Self Test
Test the DSS/BLF Console for proper lamp operation per the following
procedure.
1.Disconnect the console line cord plug from the line.
2.Press and hold console key Cl0 while reconnecting the line cord
plug to the line.

The companion station will be disabled during the time
that the console is being disconnected and reconnected.
3..Release console key ClO,and note that the BLF indicators will
each turn on in sequence beginning with the station 10 indicator.
Theindicators will then turn off and the console will become operational.Paired Stations
Station ports 10 through 41 are paired for data and for overload
protection as shown below.Console ports are not paired with any
other port.OVERLOAD PAIRED

							IMI 66-060
Maintenance
If erratic light indications or ring signals occur at a paired
station,an open data pair at either station may be the fault. 
A
station with an open data line may work properly on a short loop but
fail on along loop.
Test the wiring of stations showing this symptom
per the checkout procedure given in Chapter 2.
If a fault occurs which.causes more than 300 ma. of current to be
drawn,the overload paired stations are disabled by circuit action.
Disconnect the disabled stations and reconnect them one at a time to
isolate the faulty one.
Failure Analysis Common Equipment And Station
Figure 4-2 details a failure analysis flow chart to assist a service
technician in isolating a failure 
In a defective system.
One way to
isolate a failure is to substitute a known good assembly for a
suspected one.This is the recommended failure isolation method to
use with the system.
Connecting and disconnecting stations to the system does not affect
the stored station auto/speed dial memory data.
This data is stored
in the 
KSU memory and not at the individual stations.
Replacing the
KSU,however,causes all stored memory to be lost.
This includes all
memory dialing numbers as well as all COS programming data.

DESK/WALL REVERSAL AND WALL MOUNTING
(Executech II Multiline Telephone and Single-Line 
Keyset, Only)
Conversion
To convert a station from a standard desk model to one which can be
hung on the wall,
follow the procedure outlined below.
1.Remove and discard the pull out directory (Executech II Multiline
Keyset, only).
2.Remove the lower housing of the station; and rotate it 180
degrees.
CAUTION: The PWB contains circuitry which is sensitive to static
electricity discharge.Be sure that your body and the workplace are
properly grounded to avoid any static electricity discharge while
performing the desk/wall reversal.
3.Remove the knockouts from the desired mounting holes as
illustrated in Figure 4-3.
4.Replace the lower housing.Make sure that all wires are clear.
Wall Mounting
Mount the station directly on the wall using two, 
#lo, panhead screws
(obtained locally),or mount it on a wall jack cover plate.
1.Thread the #lO screws into the wall within l/8-inch of the
surface.Refer to Figure 4-3 for the spacing dimensions.
2.Insure that the housing is converted properly for a wall mounting
installation (see above instructions).
3.Pull out the latching lever.NOTE:
The latching lever is not present on all Executech telephone
models.
4.Position the keyhole shaped holes in the bottom of the station
over the 
#lo screws or the cover plate studs.Slide the station down
until a slight click is felt.
5.Push the latching leverin to lock the station in place.
6.To remove the station,pull out the latching lever, lift to unsnap
both screws or studs from the bottom housing, and lift the station
away from the wall.
