FIGURE 2-3: OFFSET VALUE EXAMPLE 2

Therefore, the base address in this example is:

A32 Base Address = 0xC8 * 0x1000000 (or 16,777,216)

A32 Base Address = 0xC8000000

This information is used to write to the registers of the SVM2608. (See Section 3 for more details on SVM2608 registers.)

MODULE INSTALLATION/REMOVAL

Before installing an SVM2608 module into a 6U VME mainframe, make sure that the mainframe is powered down. Insert the module into the base unit by orienting the module so that the flanges at the edge of the module can be inserted into the slot of the base unit. Position the flanges so that they fit into the module slot groove. Once the module is properly aligned, push the module back and firmly insert it into the backplane connector. The retaining screws can then be used to secure the module in the chassis.

To remove the module, power down the mainframe and remove all cabling from the module. The retaining screws can then be loosened. The ejector handles can then be used as to assist in the removal of the module.
