Chapter 4. Rack and Deskside Boards

This chapter illustrates the printed circuit assemblies for CHALLENGE and Onyx rack and deskside systems.

The chapter includes:

Note: This chapter shows SGI part numbers with a generic dash number (-xxx). Some system configurations require specific board revisions to work properly. Board revision details may be found in engineering change orders (ECOs) and field information bulletins (FIBs). Contact a support specialist to determine board revisions for a specific configuration.
