OnCell G3111/G3151/G3211/G3251 Series User’s Manual Getting Started
2-5
ATTENTION
If the modem is in GSM/GPRS mode, SIGNAL LEDs will not be illuminated if the phone
number or APN is incorrect. Check the GSM/GPRS LED if the SIM card is installed correctly.
The GSM/GPRS LEDs on the front panel provide a convenient way of checking if the SIM card
is installed properly. If the antenna is installed and the network is operating normally, then at least
one of the three SIGNAL LEDs should be illuminated at all times. If none of the GSM/GPRS and
SIGNAL LEDs are illuminated, then the SIM card may not be installed properly. This is because
the PIN code is stored on the SIM card; if the PIN code cannot be accessed, then the modem will
not be accessible over the network.
DIN-Rail Mounting
The OnCell G3111/G3151/G3211/G3251 gateways have built-in “ears” for
attaching the IP Gateway to a wall or the inside of a cabinet. We suggest
using two screws per ear to attach the IP Gateway to a wall or the inside of
a cabinet. The heads of the screws should be less than 6.0 mm in diameter,
and the shafts should be less than 3.5 mm in diameter, as shown in the
figure at the right.
Connecting the Power
Connect the 12 to 48 VDC power cord with the OnCell G3111/G3151/G3211/G3251’s power input.
If the power is properly supplied, the “PWR” LED will glow a solid green color to indicate that the
system is ready.
