5. Insert the cable supplied with a modem into the X3 RJ-12 Western jack. This is located
above the power supply connector of the modem. The catch of the RJ-12 plug must be
on the right hand side when it is inserted.
Note
It is best to hold the cable just below the RJ-12 plug. This makes it easier to insert the
plug than if you hold the RJ-12 plug itself. When inserting it, make sure that you can hear
the RJ-12 connector click into place!
6. To connect the modem to the TIM, the 9-pin D-sub connector of the mode and connecting
cable must be plugged onto the X1 connector (RS-232 interface) or X2 connector (RS-
485 interface) of the modem and screwed tight.
Note
The standard connecting cable 6NH7701-4AL for connecting the modem to a TIM module
(RS-232) is connected to the modem "head first" so that the cable comes away towards
the top.
With a TIM 4, the standard connecting cable is also connected from above. With the
TIM 3V-IE variants and the TIM 4R-IE, the cable is connected from below.
7. To install further modems in a rack, follow the same steps as described above.
8. Once all the modems are installed, the power supply can be turned on.
–
A type MD2 or MD4 modem starts up but does not indicate anything with its LEDs until
it is activated by the TIM.
– The MD3 modem starts up and indicates the presence of the power supply by its DCD
LED lighting up. The other LEDs of the modem only light up when it is activated by the
end device.
