GENERAL PRECAUTIONS
●To avoid shock or equipment damage, do not plug in or turn the system power on before completing
the installation process.
●Avoid working with the equipment during electrical storms.
●Use only commercial AC power to prevent shock or fire.
●Use the power cord supplied for the KSU.
●Do not bundle AC power cords together to prevent the cords from overheating.
●Make sure the KSU has a proper earth ground.
●Install batteries with the correct polarity to prevent damaging equipment.
●The KSU should not be placed on unstable surfaces to avoid damage.
●Although it is recommended to installed the PCBs with the system power off, all PCBs can be installed
hot (except the CCPU, EXIFU, MEMDB, VOIPDB, and VMDB).
●As some USB thumb drives may cause the system to reset, it is recommended to power down the
system prior to connecting a USB thumb drive to the CCPU.
1.1.1 Unpacking
Unpack the equipment and check it against your equipment lists. The KSU does not initially contain any PCBs.
Inspect for physical damage. If you are not sure about a component’s function, review the information for the
component within this manual. Contact your Sales Representative if you have additional questions.
Make sure you have appropriate tools for the job, including: a test set, a punch down tool, and a digital
voltmeter.

1 - 2 Chapter 1
Chapter 1 - Installing the KSUs
1.1.2 Before Installing
Make sure you have a building plan showing common equipment, extensions, the telco demarcation, and
earth ground location. The installation site must meet NEC Unified Solutions specifications in the Standard
Practices Manual (P/N N2710STD**).
1.1.3 Site Requirements
The UX5000 system can be desk-mounted, floor-mounted, wall-mounted, or rack-mounted. When wall-
mounting, it is recommended that plywood first be installed on the wall where the KSUs will be positioned,
allowing for secure anchoring. It is equipped with a bracket which can be used to secure each KSU in a desk
mount or wall mount installation. Ensure that enough space is available to allow the installation of the
additional KSU(s) above and below the KSU(s).
The system requires a three-prong dedicated 110 VAC 60 Hz circuit (NEMA 5-15 receptacle) located within 6
feet (for the 9 1/2” KSU-B) or 9 feet (for the 19” KSU-A) of theAC receptacle. Telco should install the RJ21X to
the right of the KSU. Extension blocks should be installed to the left of the KSU.
The KSU is shipped fully assembled. The following is enclosed with the KSU:
●1 black three-prong power cord (packed outside the KSU)
●1 19” mounting bracket for desktop placement or wall mounting packed outside the KSU
1.1.4 Environmental Requirements
Meeting and maintaining established environmental standards maximizes the life of the system. Be sure that
the site selected for the KSU is not:
1. In direct sunlight or in hot, cold, or humid places.
2. In dusty areas or in areas where sulfuric gases are produced.
3. In places where shocks or vibrations are frequent or strong.
4. In places where water or oil comes in contact with the unit.
5. In areas near high-frequency machines or electric welders.
6. Near computers, microwaves, air conditioners, etc.
7. Near radio antennas (including shortwave).

Equipment Overview
1.2.1 System KSUs
There are three types of KSUs:
●9 1/2” base KSU-B
●9 1/2” expansion KSU-E
●19” KSU-A
The first KSU (the Controlling KSU-B with CCPU) provides 3 slots and a power supply. One slot in the first KSU
(Controlling KSU) is used for the CCPU. Each expansion KSU (KSU-E) provides 3 slots. In a networked system
using CygniLink and an IP connection, a second CCPU can be used for a CCPU Fail-Over feature (primary/
secondary CPUs) as a backup in case of a hardware or power failure. (The CCPUs must be programmed for
primary/secondary operation.)
To expand the system further, additional KSU(s) can be added. Each KSU-B can be combined with an
expansion KSU (KSU-E) - the KSU-B providing the power to the expansion KSU.A KSU-B or combined KSU-B
/ KSU-Es can be added. These KSUs are then interconnected, for a maximum of 4 combined hard-wired KSU-
Bs and 4 KSU-Es.
In place of combining a KSU-B and KSU-E to make a 19” cabinet, you can use the 19” KSU-A cabinet. This
cabinet provides 6 slots and a power supply. The first slot in the KSU is used for the CCPU. The remaining slots
can be used for the various system PCBs required.
Up to 4 combined KSU-B/KSU-E cabinets or 19” KSU-A cabinets can be connected locally.
However, in order to reach the system’s maximum port capacity, additional KSU (either
combined KSU-B / KSU-Es or the 19” KSU-A) must be added - connected by a VoIP
connection.

Controlling/Base KSU-B
1.3.1 Controlling KSU-B vs. Base KSU-B vs. Expansion KSU-E
In the UX5000 system, there are three different versions of KSUs - the 9.5” Base KSU-B, the 9.5” Expansion
KSU-E, and the 19” KSU-A. This section will detaiil using the 9.5” KSUs.
In this documentation, the first KSU in the system requires a CCPU and is called the Controlling KSU. This is
a Base KSU-B with a CCPU installed. The system can then be expanded by attaching an Expansion KSU-E
to the right of the first cabinet. When expanding a system past two KSUs, the next KSU is a Base KSU-B
(without a CCPU), which can then also have an Expansion KSU-E attached.
Each KSU measures 9.5 inches wide. With an Expansion KSU connected, the maximum width is 19 inches.
The KSU-B provides the power supply, connections on the power supply unit for an external backup battery, 3
universal slots for the CCPU and other optional PCBs (such as ESIU, SLIU, VOIPU, etc.) and an EXIFU
(expansion) slot. All slots are connected to the backplane.
AKSU-B can be combined with an Expansion KSU-E,.Additional pairs of KSU-B/KSU-E’s can be connected to
the system (up to 4 KSU sets maximum). Expansion Interface Units (EXIFU-B1 and EXIFU-E1) are installed in
the EXIFU slot in the KSU-Bs (base KSUs). The connection to the Expansion Interface Unit is made using a
CAT 5 cable.
The Controlling KSU-B is used to install the system PCBs, including one slot for the CCPU. It can
accommodate up to 16 trunk ports and 32 ports extension ports. An Expansion KSU-E can be installed to
the right of the Controlling or Base KSU-B to accommodate an additional 48 ports (40 trunk/80 stations
max.). With a maximum of 4 KSU-Bs and 4 Expansion KSU-Es or 4 19” KSU-As, the system will provide up
to 184 trunks and 320 extensions and, with IP connections, a maximum of 200 trunk ports and 512 station
ports is possible.
To reach these limits, a MEMDB would be required as well as a license for the expanded ports.

Expansion KSU-E
1.4.1 Expansion KSU-E
The Expansion KSU-E is used to install additional system PCBs and connects to the right of the Controlling/
Base KSU-B. Combined with the Controllling/Base KSU-B, it can accommodate up to 96 ports (40 trunk/80
stations max.). With a maximum of 4 hard-wired Controlling/Base KSU-Bs and 4 Expansion KSUs, the system
will provide up to 184 trunks and 320 extensions and, with IP connections, a maximum of 200 trunk ports and
512 station ports is possible.
To reach these limits, a MEMDB would be required as well as a license for the expanded ports.
Each KSU measures 9.5 inches wide. A Controlling/Base KSU with an Expansion KSU connected is a total of
19 inches.
The Expansion KSU provide 3 universal slots for the optional PCBs (such as ESIU, SLIU, VOIPU, etc.) and an
EXIFU (expansion) slot. All slots are connected to the backplane. The Controlling/Base KSU provides the
power through the backboard connector.
AKSU-B can be combined with an Expansion KSU-E,.Additional pairs of KSU-B/KSU-E’s can be connected to
the system (up to 4 KSU sets maximum). Expansion Interface Units (EXIFU-B1 and EXIFU-E1) are installed in
the EXIFU slot in the KSU-Bs (base KSUs). The connection to the Expansion Interface Unit is made using a
CAT 5 cable.

! Important !
●The Expansion KSU must only be installed with the system power OFF.

1 - 10 Chapter 1
Chapter 1 - Installing the KSUs
The Expansion KSU uses an expansion bracket which attaches to the right side of the Controlling/Base KSU.
When multiple cabinets (combined KSU-B and KSU-E or a KSU-A) are to be connected, an Expansion KSU
kit is required to connect the KSUs together (using the EXIFU PCB).
●Note: When wall-mounting a UX5000 system, make sure the wall can support the weight of the
KSUs. It is recommended that plywood first be installed on the wall where the KSUs will be positioned,
allowing for secure anchoring.
1.4.2 Before Installing an Expansion KSU
1. The system must be powered down (if previously turned on).
2. Remove the Controlling/Base KSU from the current mounting (if necessary).
1.4.3 Connecting the KSU-B and KSU-E Cabinets Together
To secure the 9.5” Base and Expansion KSUs together, follow the instructions below.
1. Remove the metal plate covering the expansion connector on the right side of the KSU-B.
