Option Specifications
This chapter describes the options currently available for MicroVAX and
VAXserver 3400 systems. Some of the options described are already
installed. If you want to add other options to your system, your DIGITAL
sales
representative can advise you. Chapter 3 offers some guidelines on
determining what options you can add to your system.
Options must be properly configured so that the system recognizes them.
Each option in a system has a device address, commonly referred to as a
Control
and Status Register (CSR) address, and an interrupt vector that
must be set when the option is installed. Options are usually configured
by
adjusting switches or jumpers on the modules. Your DIGITAL service
representative configures the option properly when installing the option in
your system.
Self-maintenance customers can find information on
setting CSR addresses
and interrupt vectors in the Micro VAX Hardware Information volume of the
KA640 CPU Systems Maintenance.
