The main cabinet (DXCBM) contains the main power supply and up
Introducing
to 12 printed-wire-boards. The cabinet is 26 inches wide, 19 inches
high, and twelve inches deep, and it’s comprised of the following
The DXP Main components:
.
Cabinet
l an external, ventilated sheet-metal housing with detachable
front cover,
l the card cage-the metal frame into which you insert the
printedwire-boards,
.
and the backplane-a large printed-wire-board that provides
the circuitry to connect the individual boards together.
When you first open the main cabinet, you will see an empty space
where the power supply is to be mounted. The power supply provides
DC operating power for the DXP printed-wire boards and also for the
individual digital stations as well. The power supply is shipped
separately, and we’ll cover it later in this manual.
The space directly above the power supply is reserved for the ring
generator. Industry-standard telephones require voltage to enable
ringing and to turn on the message-waiting lights; the ring generator
supplies the required voltage to all of the IST stations on the DXP.
You must have a ring generator if you are going to use IST stations,
and you must have a ring generator in each cabinet that supports IST
stations. It’s a good idea, therefore, to plan on configuring all of your
IST stations through one of the cabinets.
Moving from left to right in the main cabinet, the slots for the 12
boards are as follows:
- Interface board
- Services board
- CPU Board (RAM Card/Software Card)
- Universal 1 / Auxiliary Board
- Universal 2 / Auxiliary Board
- Universal slots 3,4,5
-
Line slots 4, 3, 2, 1.
