Power supply
The DCN-CCU2 supplies power to the optical network (refer to section 3.1 DCN-CCU2).
If more power is necessary, you must install external power supplies in the optical network.
The devices below can connect to external power supplies:
–
–
DCN-CCU2
The central control unit supplies power to:
–
–
For an overview of the maximum power that the central control unit can supply refer to the
figure.
Figure 4.9 Optical network power supply: DCN-CCU2
If the DCN-CCU2 is configured as a master CCU in a multi CCU system or the DCN-CCU2 is in
stand-alone mode, it will supply power to the optical network. If a glass optical fiber is used to
connect a remote slave CCU, the optical fiber interface needs an external power supply. Refer
to chapter 'Power supply' earlier in this chapter.
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 set to off and the devices connected to the
central control unit do not operate. The socket checks every 4 seconds.
NOTICE!
If only one of the optical network sockets has a power overload, the two overload LEDs are
on, and the power will be removed from both sockets.
