Power Supply
The system uses an industrial power supply unit with natural cooling and an auxiliary
external fan, which is switched on automatically whenever the power supply
temperature exceeds 70°C. The power supply unit is designed with a 30% reserve
even under the maximum load.
Warning
The PRI/CPU/VoIP card positions are fixed and may not be interchanged in
the rack.
Note
Please keep all cards in the right positions. Wrong positions will cause
malfunction of the whole system!
In the case of VoIP card replacement by ISDN PRI (and vice versa) please
read the instructions in Section .2.4 Installation
