3.1 Classification of Boards

There are three types of boards in the SoftX3000: Front board

Back board

Backplane

Both the front boards and the back boards are inserted in the backplane.

Table 3-1 lists the functions of the front boards, the back boards, and the backplane.

Table 3-1Functions of boards used in the SoftX3000Board Function

Front board Service processing boards and management control board

Back board Protocol processing boards and interface boards

Backplane Providing a communication channel for other boards

All the SoftX3000 boards are hot swappable. This means that the board is swappable while in

operation. Some of the boards have a hot-swapping LED OFFLINE on the front panel and ahot-swapping switch on the ejector lever.

When you insert a board into the frame and restore the ejector lever, the hot-swapping

switch is closed.

When you push open the ejector lever, the switch is open.

Then the MBUS module of the board sends a board-swapping request to the active SMUIin the frame and terminates all services on the board.

When the hot-swapping LED is on, you can unplug the board.

Figure 3-1 shows the board insertion mode in the SoftX3000.

Front boards of the SoftX3000 are USP boards that adopt two types of hardware configuration:

750B and 750C.

750B is characterized by:

MPC750 processor with the clock frequency of 500 MHz

Two FE interfaces connecting with two star Ethernet buses on the backplane Memory of 512 MB

64-bit CPCI bus interface at the rate of 33 Mbit/s

FLASH memory of 16 MB
