Introduction

This chapter provides information on powering up the MVME2300SC
VME processor module after its installation in a system, and describes the
functionality of the switches, status indicators, and I/O ports on the front
panels of the MVME2300SC and PMCspan modules.
For programming information, consult the MVME2300 Series VME
Processor Module Programmer's Reference Guide as listed in Appendix
C, Related Documentation.
