3.1.5.1 Control keys
An Aastra XS12 (AXS12) iPBX includes a main cabinet, and possibly an expansion
cabinet (version A2XS12).
The main cabinet and the expansion cabinets are in the form of a 19" metal cabinet, 2 U,
in which the subassemblies required for the iPBX to operate are inserted.
The cabinets are adapted to 19" racks with the help of brackets. They can also simply be
placed on the floor or on a piece of furniture, or wall-mounted.
The cabinets can be stacked or set side by side. In the case of wall-mounting, the
expansion cabinet can only be fitted beside the basic cabinet.
The two cabinets present a common structure:
• A slot, located at the base of the cabinet, reserved for the main UCV-S card.
• An EXT1-S12 card, fitted with:
• Extension and T0/S0 interface sockets
• RJ45 sockets for the analogue and digital equipment interfaces on the front panel.
• 3 slots, located in the upper part of the cabinet, reserved for expansion cards (RJ45
format). RJ cards are locked on the front panel of the cabinet, blanking plates must be
fitted in unused slots.
• Air inlets/outlets for ventilating the elements in the cabinet are available on:
• left-hand side: fresh air inlet
• right-hand side: hot air outlet.
• You can add or remove an expansion card from the front panel without opening the
cover.
• The external cables (for the main card and the expansion cards) are connected on the
front panel of the cabinet. The mains, battery (optional) connection, as well as the
connection to the expansion cabinet are at the back of the cabinet.
• The list of subassemblies which can be inserted in the main cabinet and expansion
cabinets is provided in Section3.4.
