3.4 Power Supply Interface
3.4.1 iTegno 3932
The iTegno 3932 modem DC IN terminal is via a Y-cable, connecting the open ending of the power cord to a DC
supply and standard D-sub 9-pin (female) connector from the modem.
The power supply rating is:

Voltage
Minimum Voltage Input
5V
Maximum Voltage Input
32V
A regulated 5V DC input voltage is recommended for operating the modem. A power voltage exceeding 32V
supplied to the modem may result in permanent damage.
A 2A fuse is connected in series with the DC IN, when there is a surge, it protects the circuit.
