2N® StarGate

Basic Dimensions

2N® StarGate is the biggest GSM gateway in the 2N® PRI gateway family. The system is integrated in a 19" subrack of the height of 3U and depth of 360mm. The front side is open, equipped with slots for plug-in boards with front panels. The panel includes the main switch. In case not all GSM/UMTS cards are plugged in, the vacant front section must be covered with a fixed panel(s).

The whole backside is covered with a panel with a built-in active fan, which is automatically switched on whenever the power supply temperature exceeds 70°C. The main power supply unit is located in front of the fan. The bottom and upper sides are covered by perforated sheet and 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.

Front Side Division

The subrack width is divided into an 8HP-wide mains panel and 19x4HP-wide modules in the following sequence (from right to left)

 

VoIP version

  • Fixed panel with a main switch (AC type) or power connectors (DC type) – 8HP
  • VoIP card – 4HP
  • Basic or enhanced CPU card – 4HP
  • Empty position – 4HP
  • GSM or UMTS cards (one for two GSM/UMTS channels) – Remaining space (each 4HP)

ISDN version

  • Fixed panel with a main switch (AC type) or power connectors (DC type) – 8HP
  • Empty position – 4HP
  • Basic or enhanced CPU card – 4HP
  • 1ISDN PRI or 2ISDN PRI card – 4HP
  • GSM or UMTS cards (one for two GSM/UMTS channels) – Remaining space (each 4HP)

ISDN + VoIP version

  • Fixed panel with a main switch (AC type) or power connectors (DC type) – 8HP
  • VoIP card – 4HP
  • Basic or enhanced CPU card – 4HP
  • 1ISDN PRI or 2ISDN PRI card – 4HP
  • GSM or UMTS cards (one for two GSM/UMTS channels) – Remaining space (each 4HP)

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.

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.

 

Power supply types

  • Internal 90 – 260V / 50 – 60 Hz (output 5V / 30A).
  • 2x Internal 90 – 260V / 50 – 60 Hz (output 5V / 30A) (redundant).
  • Internal 48 DC (output 5V / 30A).

The type of the power supply unit to be used depends on the part number.

Caution

  • Make sure that the incoming supply is matching the requested values!
  • High voltage may cause a serious injury or death!

Tip

  • You are recommended to connect the gateway to the UPS system.
