3.5.4 Overload indication
Each optical network socket of the central control unit
has a red LED that comes on to show that there is a
power overload. An overload occurs when the
necessary power for the devices is greater than that
supplied. The sockets are deactivated and the devices
connected to the central control unit do not operate.
The socket checks every 8 seconds for power overloads.

Note
If only one of the optical network sockets has a
power overload, the two overload LEDs come
