FIGURE 2-1 MOUNTING THE KSU
2.3 AC Power Selection ( See FIGURE 2-2 )
Before pluging in the KSU, set the AC power selection connector.
The Power board of each system has three power connectors. One is for 0V
(Ground) and the rest are for 110V/220V selection. The KSU has two lines; one
black and the other sky-blue (or white); with a pink power connection jack.
Verify the AC voltage and connect the sky-blue (or white) line to the 0V connector,
and black to the AC power connector.
Connect the BLACK wire to
110VAC or 220VAC power(LIVE).
Connect the S K Y - B L U E ( o r
w h i t e )wire to 0V (NEUTRAL)

5. CONNECTING TELEPHONE LINES
5.1 SAFETY PRECAUTIONS
To limit the risk of personal injury, always follow these precautions before
connecting to TELCO circuits:
● Never install telephone wiring during a lightning storm.
● Never install telephone jacks in a wet location unless the jack is specifically
designed for wet locations.
● Never touch uninsulated telephone wires or terminals unless the telephone line
has been disconnected at the network interface.
● Use caution when installing or modifying telephone lines.
5.2 LOOP START LINES
● Using one pair twisted #24 AWG or #26 AWG jumper wire, cross-connect each
loop start C.O. line to the trunk port.
● Refer to FIGURE 4-1 through 4-7 and 4-8.
6. CONNECTING STATION EQUIPMENT
Using one pair twisted #24 AWG or #26 AWG jumper wire, cross-connect each
keyset/AOM or single-line telephone to the keyset port or SLI port of your choice.
6.1 CONNECTING KEYSET / AOM (FIGURE 6-1)
The NX-308 system has seven hybrid ports and the NX-1232 system has eight
hybrid ports.Either a keyset or a single-line telephone may be connected to a
hybrid port. Before connecting station equipment to a hybrid port, the switches on
the Base Board must be set to keyset or SLT.
Each switch is composed of four sections, set to ON/ON/OFF/OFF to connect a
keyset to the hybrid port.

Each numbered switch has four
sections: ❶ ❷ ❸ ❹ .
To connect a keyset to a hybrid port,
they are set to ON/ ON/ OFF/ OFF.

6.1.1 NX-308 - Related Switch Location (FIGURE 6-3)
To connect a keyset or AOM to station #2 to #8 of basic KSU, the related
DIP switches should be set as follows: (Station #1 is a keyset-only station.)

8. BEFORE POWER UP
During initial installation, it is best to verify proper system operation before plugging in
any amphenol-type cables to the MDF. If you have already plugged the cables in,
unplug them. Verify that the AC voltage at the dedicated electric outlet is correct.
Make sure the AC power switch is in the OFF position and memory back-up switch is
ON. Plug the KSU power cord into the dedicated polarized AC outlet. Turn the AC
power switch to the ON position, and verify the status of the "POWER", "MONITOR",
and "IDLE" LEDs on the cover of the KSU. A steady "POWER" LED indicates the
presence of power, and a blinking "MONITOR" LED indicates that the main
processor is functioning. A steady "IDLE" LED indicates that no one is using the
system. If the "POWER" LED fails to illuminate, unplug the system, remove the power
supply, and check the AC fuse located on the bottom.
If the fuse is good but the "POWER" LED does not illuminate, you must correct the
problem before continuing., Turn off the power switch., Unplug all expansion cards
except Base board. Turn the system on. Check the "POWER" LED again. If the
problem is corrected, you have a defective card. Test and remove the faulty card
before continuing.
If the LED still does not light, unplug the KSU and change power supplies or Base
board. This in all probability will solve the problem. If it does not, contact Samsung
Technical Support.
