DS ports on the front of the IP406 V2 control units must not be used for extensions that are external to the main
building.
The protection device should be installed as per the instructions supplied with the device. The ground points on the IP
Office control unit and the DS modules must be connected to a protective ground using 18AWG wire with a green and
yellow sleeve.
Typically the IROBs 2 RJ45 EQUIPMENT ports are straight through connected to the 2 RJ45 LINE ports. This allows existing
RJ45 structured cabling, using pins 4 and 5, to be used without rewiring for up to two DS connection. However each of
these ports can be used to connect a second extension using pins 3 and 6.
