System Overview 1-9
➌
Power LED (green). Lights when the power button is pressed.
➍
Reset button. A momentary contact switch that restarts the system and
reinitializes the console firmware. Power-up messages are displayed, and
then the console prompt is displayed or the operating system boot messages
are displayed, depending on how the startup sequence has been defined.
➎
Halt LED (amber). Lights when you press the Halt button.
➏
Halt button. Halts the system.
If Tru64 UNIX or OpenVMS is running, pressing the Halt button halts the
operating system and returns to the SRM console. Pressing the Halt button
does not halt the Windows NT operating system.
If the Halt button is latched when the system is reset or powered up, the
system halts in the SRM console, regardless of the operating system. UNIX
and OpenVMS systems that are configured to autoboot cannot boot until the
Halt button is unlatched.
Commands issued from the remote management console (RMC) can be used to
reset, halt, and power the system on or off. For information on RMC, see
Chapter 4.
