Installing MT1100C, MT1102C into the Rack Nest 2/14 Card Cage
To install MT1100C, MT1102C card into the Rack Nest 2/14 card cage:

3. Push the card into the cage until it is fully inserted into the edge connector
inside the rack.
4. Tighten the screws on front panel of the modem card.
Connecting the Interfaces
MT1100C and MT1102C use the Rack Nest 2/14 rear panel terminal block ports for
the line connections. The 25-pin D-type female connector serves as a DTE port.
1. Remove the protection cover from the terminal block connectors.
2. Connect the terminal block to the Rack Nest 2/14 terminal block connector.
3. Connect the line to the terminal block as follows: connect transmit pair to the
terminals marked XMT, the receive pair to the terminals marked RCV, and the
fifth screw to ground (optional).
4. If required, attach the appropriate interface adapter to the DB-25 connector
on the card cage rear panel.
5. Connect the DTE cable to the DB-25 connector or other side of the interface
adapter (depending on your version of the card interface).
6. Connect power to the Rack Nest 2/14 card cage:
To connect AC power, connect the power cable to the mains supply.
To connect DC power, refer to DC power supply connection supplement
of the Rack Nest 2/14 installation and operation manual.
The Rack Nest 2/14 card cage has no power switch. Operation starts when the
power is applied to the rear panel POWER connector. When applying power,
first connect the plug of the power cord to the Rack Nest 2/14 POWER
connector and then to the mains power source (outlet).
