KSU power transformer (where the KSU AC power cord is located) is positioned in the 
upper left corner. The power switch and Power/Heartbeat LED are positioned at the 
left side of the KSU toward the bottom.

3 x 8 Module
The 3 x 8 module requires one 25-pair amphenol type (male) ended station cable to 
extend the interface ports to the MDF. The station cable is plugged into the female...

The cable is then routed out of the KSU through an opening at the lower left of the KSU 
housing. A cable restraint clamp is provided and may be used to secure cables exiting the 
KSU. The 25-pair cable is then terminated on a punch-down terminal block on the MDF. 
Refer to Figure 2-19: Wiring Designations for 3 x 8 Modules. 
The 3 x 8 module is installed to expand system capacity and is housed in the KSU in 
stacking fashion over the initial 3 x 8 module....

5. Remove one of the module-securing screws only so the existing board stays in place, 
and retain the screw for later use.
6. Insert one of the stand-off posts into the screw position where the screw from Step 5 
was removed.
7. Tighten securely by hand, then snug tight using a small hand tool. It is very important 
not to over-tighten any screw or stand-off post as damage to the board may occur.
8. Repeat Steps 5 through 7, until all module screws are replaced with stand-off...

6-Port CO Module
The 6-Port CO Module is installed to increase system capacity of CO lines. The 6-Port CO 
Module is shipped with two 6-conductor cords, two surface-mount modular jacks and 
four stand-off posts. Regardless of how many 3 x 8 modules are installed, only one 6-Port 
CO Module may be installed. The 6-Port CO Module must be the last module installed. For 
example, if a 6-Port CO Module is first installed as the first Expansion Module (JP3), and a 
3 x 8 module is then...

9. Connect two 6-Conductor Line Cords into Jacks on 6-Port CO Module, and feed the 
Cables through the opening in the lower left of the cabinet.
10. Mark CO Line Cords.
11. Replace the KSU cover and secure it with cover screws.
12. Restore KSU power when all wiring is complete, or continue with the installation 
process.

The 6-Port CO Module must be installed in the last available expansion BUS connector on 
the CPU Module. That is, if...

Option Module
The Option Module provides advanced call processing features like External Call Forward, 
Automatic Busy Redial, etc. (Generally, features that require enhanced call monitoring via 
Tone Detectors and DTMF receivers). The Option Module is equipped with two DTMF 
receivers and two Tone Detectors. In addition, the Option Module provides two music 
source inputs (one that replaces the Standard MOH/BGM Module), one External Page 
Zone port and one Loud Bell Control...

Standard MOH/BGM Module
The Standard MOH/BGM Module is shipped installed in the KSU. In the event that the 
Option Module was installed and the Standard MOH/BGM Module is to be re-installed, 
follow these steps:
1. Make sure KSU power is OFF, and the cover is removed.
2. Connect grounded wrist strap to a suitable earth ground.
3. Locate the four screws used to secure the Option Module to the Option Module 
stand-off posts. Remove each screw...

6. Terminating Connections
3 x 8 Module(s)
1. The CO line connections (as well as station connections) are made to the 3 x 8 
Standard Module and Expansion Module(s) via the 25-pair connector located along 
the bottom edge of the installed module. Refer to Figure 2-19: Wiring Designations for 
3 x 8 Modules.
2. Once the 25-pair cable is terminated on an industry standard 66M1-50 block, cross-
connect (jumper wire) should be used to extend the CO...

6-Port CO Module
1. CO line interface to the 6-Port CO Module is made through two RJ25 type modular 
connectors on the 6-Port CO Module located along the bottom edge of the installed 
module. CO line ports (1-3) of the 6-Port CO Module are connected through RJ25 
connector CO 1-3 (positioned toward the left/center of the installed module) and CO 
line ports (4-6) of the 6-Port CO Module are connected through RJ25 connector CO 4-
6...
