2. Tighten the screws to prevent the power supply cable from coming loose, and cover the power
supply interface set.
3. Insert the wiring terminal of the installed power supply cable into the standby power supply
input port of the DA, and tighten the screws at both ends.
4. Insert the other end of the standby power supply cable into the standby power supply
equipment, such as the Uninterrupted Power Supply (UPS).
5. When there is no standby power supply, the main and standby power supply can be
connected to each other.
Connecting the NPM Power Supply Cable
Connecting the Power Adapter
The X-NPMS can be powered by a power adapter. Insert one end of the power supply adapter into
the NPM power supply input port, and connect the other end of the power supply adapter cable to
the power supply equipment.
Connecting the External Power Supply
The X-NPMS can be powered by external equipment, such as the X-DCS3000. Insert one end of
the power supply adapter into the NPM power supply input port, and connect the other end of the
power supply adapter cable to the power supply equipment. Pay attention to the different DC input
interface places. The output current is 1A.
Connecting the Power over Ethernet
The X-NPMS can be powered by the power over Ethernet. Use a twisted pair cable to connect the
X-NPMS with POE switch. There is no need to connect to power supply cables or power adapter.
Caution!
When X-NPMS is connected to many key extension modules and powered by POE, we
recommend to use POE switcher, which support IEEE802.3 to satisfy the power supply needs.
Connecting the NRI with the Telephone Interface
If users want to enable the telephone interface function, the telephone interface device has to
connect to audio input interface (auxiliary input) and communication control port of NRI. The steps
are as described below:
Connect the audio output of the 3
•
NRI, make sure that auxiliary input has been configured as a telephone task in the Config
software.
Connect the RS-485 (A2/B2 port) of the NRI to the SLAVE port (A/B port) of the 3
•
telephone interface, port A2 connects with port A; port B2 connect with port B.
Connect the telephone interface device RJ-11 port to the PSTN switch or VoIP gateway, to
•
enable the connection between X-618 system and telephone network interface.
