This connector is an IEC-60320 Type C14 (male) three-prong connector, for
connection with an IEC-60320 Type C13 (female) three-prong plug. Note the
following:
Input Power: 130W maximum
•
Input Voltage: 90 to 132 V or 175 to 254 VAC. The unit switches voltage
•
ranges automatically.
The fuse holder is press-fit into the body of the IEC power module. Two 5mm 1
Amp Slo-Blo type fuses are installed here for line and neutral fusing.
PROPER GROUNDING PROTECTION IS REQUIRED. You must
connect the equipment to the protective earth connection at all
times. Use this ground stud during installation, configuration, and
operation.
The AC power interface provides the safety ground.
Use this #10-32 stud, located adjacent to the power interface module, for
connecting a common chassis ground among equipment.
This type TNC female connector supplies a master external reference to the entire
chassis. Functional features include:
Frequency selectable at 1MHz, 5 MHz, or 10 MHz
•
Input impedance to 50Ω unbalanced
•
Voltage up to 3 V (rms)
•
Sine or square waveform (50% duty cycle)
•
This 8-pin 'RJ-45' 10/100 BaseT port provides access to the Ethernet Interface for
remote control of the modem using using SNMP, HTTP/HTTPS or Telnet.
