Make sure the AC POWER switch is turned OFF 
Installing an EXP with 
the power on may damage 
the EXP and the KSlJ. 
Install the EXPs one at a time. 
With the component side facing out, carefully 
slide the EXP into place. Make sure that the 
connector on the back of the EXP is securely 
seated on the corresponding connector be- 
neath it. 
CAUTION 
If 
any of the connector pins are bent while at- 
tempting installation, the Expansion Module 
(and any modules that are installed on top of it) 
will not operate properly. 
(4) Check the station fuse on the bottom edge of 
the EXF? This should be a 2A, 25OV AGC 2 
(fast-acting) fuse. 
(5) Set the address selection switches that are 
used to indicate the position of the EXP in re- 
lation to the KSU. 
These switches must be set 
correctly in order for the system to operateproper- 
Zy. 
Outlined below are the switch settings for 
each possible EXP location. To aid in proper 
installation, these settings are also silk- 
screened directly on the EXF?

E PERFORM THE NETWORK SELF TEST 
NOTE: The 
network self test function is available 
only in the 
Intermediate and Advanced software pack- 
ages. Also, an APM is required to perform all tests 
other than the system board status test. 
6.12 After the last module is installed, the network 
self test for the full system should be performed. The 
self test function tests the voice channels and switch- 
ing matrices of the system. The test should performed 
for every new installation, whenever a new board or 
module is installed, and whenever a voice channel 
problem arises. 
6.13 Refer to PROGRAMMING, page 5-5, for in- 
formation on setting up the KSU for programming. 
Then, see page 5-128 for details on performing the 
network self test. Perform the full system test (menu 
selection [G] on the self test menu). If any board or 
module fails the test, it must be replaced. 
G. COMPLETING THE KSU INSTALLATION 
6.14 
Complete the KSU installation as follows: 
(1) Ensure that the AC POWER switch is OFF. 
(2) Slide the KSU cover plates into place and re- 
place the screws. 
(3) Connect each labeled station female amphe- 
nol-type connector to the 50-pin male connec- 
tor on the corresponding KCB, EXP, or APM. 
(4) Connect each mod-to-mod C.O. line cord to 
the associated C.O. jack on the KCB or EXl? 
(5) Turn ON the AC POWER switch.

Install all keysets as follows: 
(1) Before mounting the modular jack assembly 
and connecting the keyset, measure the volt- 
age on the RED terminal of the modular jack 
assembly with respect to the GREEN termi- 
nal. (Ihe “common” probe of the voltmeter is 
placed on the GREEN terminal.) It must mea- 
sure +3OVDC (22.OVDC). If -30VDC is 
measured, check the cabling for a reversed 
pair. 
If the power pair (W/BE, BL/W) is reversed, in- 
stalling a keyset will open the fuse on the KSU 
Control Board or ansion Module. This af-
