then connect the adapter connector to the gateway. Refer to the status indicators on
p. 15 above.
Warning
 Connecting a defective or inappropriate power supply adapter may lead to
a temporary or permanent 2N
® VoiceBlue Next error!
 Never connect 2N ® VoiceBlue Next using the PoE and a local adapter at
the same time to avoid permanent 2N ® VoiceBlue Next malfunction!
 Check whether the antenna is connected before plugging the adapter.
Feeding the device without antenna connection may result in the
GSM module transmitter damage.
Antenna Connection
2N ® VoiceBlue Next is equipped with a SMA female antenna connector for all the
GSM/UMTS modules. The external antenna should always be installed vertically on a
site with a good wireless signal.
Warning
 Tighten the antenna connector gently with your hand – never use a
wrench!
 Being a source of radio frequency emissions, the 2N ® VoiceBlue Next
antenna should not occur in the close vicinity of the human body. The
health hazard is higher than with mobile phones as, generally, gateways
shared by multiple users show a very high traffic.
Note
 The antenna has a sufficient gain for a trouble-free operation under
normal conditions. If the signal is poor or you want to place your antenna
separately from 2N
® VoiceBlue Next, you can use an antenna with an
SMA-connector terminated cable. The antenna should be mounted
vertically.
 Refer to the Technical Parameters section for the antenna and cable
parameters.
Ethernet Cable Connection
To connect 2N ® VoiceBlue Next into an Ethernet network use a standard straight cable
terminated with RJ-45 connectors (included in the package). The GSM gateway
supports the 10BaseT and 100BaseT standards, the Ethernet connection status is
indicated by the status LED indicators located on the RJ-45 connector (refer to p. 15
for details).
For the Ethernet interface factory settings for 2N ® VoiceBlue Next refer to Subs. 2.2,
p. 19.
