2.6 Connecting data cables
In general, adhere to the following recommendations for data cable 
connections in environments with high electrical interference levels:
 Keep the length of the data cables as short as possible. 
 Use optical data cables for the data transmission between the buildings.
 When using copper cables, provide a sufficient gap between the power 
supply cables and the data cables. Ideally, install the cables in separate 
cable channels.
 Use shielded cables.
Note: Verify that you connect only optical ports with the same optical 
transmission properties with each other.
For further information see “10/100 Mbit/s twisted pair port” on page 24.
For further information see “100 Mbit/s F/O port” on page 25.
 
 Connect the device via the INTERNAL port to the internal network or the 
local computer that you want to help protect.
 Connect the device via the EXTERNAL port to the external network, such 
as the Internet. This network is used to set up the connections to the 
external device or external network.
