Installation and Maintenance Manual

System Expansion

To equip the switch with more than 8 extensions or to add an Internet or Options module, a backplane, mounted on a second wall bracket, is needed.

The power must be disconnected to install the backplane or expansion modules.

Installing the Backplane wall bracket

The CCU and Backplane brackets are identical. However when both are installed the backplane bracket is inverted so that it meshes closely with the CCU bracket.

Locate the second bracket and mark the screw holes. Drill and plug the holes in the wall at the marked locations. The holes should be deep enough to accept a 2.5cm screw.

Mount the second bracket ensuring the two brackets are correctly interlocked and that sufficient clearance is provided on all sides.

Mounting the CCU with two brackets

Slide the CCU on to the brackets from the left-hand side. Ensure that the locking mechanism is activated.
