1.1. 19” Subrack
1.1.1. Basic Dimensions
The system is integrated in a 19’’ subrack of the height of 3U and depth of 360mm. The
front side is open, equipped with guides for plug-in boards with front panels – the panel
including a mains switch is part of the subrack. In case not all GSM boards are plugged in, the
free section of the front side must be covered with a fixed panel (fixed panels).
The back side is completely covered with a panel with a built-in ventilator, which is
switched by a thermostat for higher reliability and longer life. An AC mains supply unit is located
in front of the ventilator. The bottom and upper sides are covered with perforated sheet, the
assembly flanges are provided with handrails.
The system bus is designed as a printed circuit board (PCB) with DIN connectors and
fitted to the inner subrack carrier profiles.
1.1.2. Front Side Division
The subrack width is divided into an 8HP-wide mains panel and 19 4HP-wide modules in
the following sequence (from right to left):
•
8HP fixed panel with a mains switch, fuse and mains cable socket;
•
4HP CPU board (must be included in any case);
• 4HP AUX board (must be included in any case);

1.3. Power Supply
1.3.1. Description
The system uses an industrial mains supply unit with primary (input) voltage of 100-
240VAC 50/60Hz and secondary (output) voltage of 5V/30A with natural cooling and an
auxiliary external ventilator, which is switched on
automatically whenever the power supply
temperature exceeds 70°C. The supply is designed with a 30% reserve even under the
maximum load.
