Chapter 8 Using the System Control Manager

The system control manager (SCM) communicates with microprocessors on the console serial bus (CSB) to monitor and manage the system. The SCM also provides remote server management functions.

This chapter explains the operation and use of the SCM. Sections are:

•Console Serial Bus Subsystem

•System Control Manager

•SCM COM1 Operating Mode

•Console Device Setup

•Entering the SCM

•SRM Environment Variables for COM1

•SCM Command-Line Interface

•Troubleshooting Tips

For more information on SCM commands, see the AlphaServer GS80/160/320 Firmware Reference Manual.
