System Setup
The system starts up and loads the operating system. A welcome message is displayed. If the
system does not turn on or boot after pressing the power button, refer to the “Power
Problems” section in Chapter 6 for troubleshooting instructions.
After the welcome message display, a series of POST (Power–On Self–Test) messages
appears. The POST messages indicate if the system is running well or not. If an error
condition occurs, note any error messages appearing on the display. Go to the “POST Error
Indicators” section in Chapter 7 for more information.
Aside from the POST messages, you can determine if the system is in good condition by
checking if the following occurred:
Power indicator
on the front panel lights up (green).
•
•
Num Lock, Caps Lock, and Scroll Lock indicators on the keyboard light up.
NOTE:
Only the Num Lock indicator would remain lit up.
To Turn Off the Server
To turn off the server:
1. Close all open applications.
2. Use the shut down command applicable to server’s NOS.
3. When prompted, press the power button
on the front panel.
If you want to force the server to shut down (for example if the operating system has
crashed), press and hold down the power button for approximately 5 seconds. Quickly
pressing the button may put the server in a sleep mode only.
IMPORTANT:
The power supply will continue to provide standby current to the server until the power
cord is disconnected from the rear panel. When you disconnect the AC power, the server remembers
the current power state (on or off) and returns to this state when AC power is reconnected.
Sleep Modes
The HP ProLiant ML110 server supports the ACPI (Advanced Configuration and Power
Interface) standard, which is a key component of a NOS’ directed power management. The
supported features are available when an ACPI-compliant NOS is installed on the server. The
term
sleep mode
or
sleep state
refers to any of several reduced power consumption states in
which normal NOS activity has ceased.
The HP ProLiant ML110 server supports two sleep modes:
•
Standby
This sleep mode has a short wake-up time. During this state the server appears to be
off—the monitor appears blank and there is no CD-ROM or internal hard drive activity
(IDE or SCSI); however, the power LED displays a blinking green light and the system
fan continues to operate.
