Connecting Devices

Sockets

The operation of a communications system can be impaired by interference in the power supply caused by other equipment, especially photocopiers, laser printers, electric typewriters, air conditioning, fan heaters, vacuum cleaners and refrigerators. For this reason, please:

Connect the Eumex 704PC LAN to a socket as far away as possible from sockets used for the above-mentioned equipment. The best solution is to use a separate circuit for the Eumex 704PC LAN.

Ensure that the AC adapter is always seated securely in its socket. Adapters or sockets not firmly secured can lead to faulty operation and possibly fires! Have such sources of danger repaired by qualified personnel without delay.

Only use multiple sockets that are adequately safe. This can be assumed only if the multiple socket displays the proof of its compliance with safety standards (e.g. the CE symbol). Failure to observe this can lead to faulty operation of the Eumex 704PC LAN, and even fires.

Connect the Eumex 704PC LAN to the mains supply. The connector socket for the AC adapter is on the lower side of the Eumex 704PC LAN. Insert the corresponding power cable plug into the socket marked , then insert the AC adapter into the mains power socket.

When the T-ISDN LED lights up, it means that the NTBA is operational. If the LED flashes, it means that external calls are not possible.

Now you can make and accept internal and external calls. In this setting, incoming calls are signalled simultaneously on all terminals. External calls can only be made to specific terminals when you have assigned them MSNs. Please refer to the chapter entitled "Configuring the System" for information on this procedure.

In the case of faulty operation, please also refer to the notes in the Appendix (p. 110).
