TURNING ON THE SERVER
Turn on the server and follow the on-screen instructions.
1. Power on the display unit and other external devices.
NOTE: If the power cord is connected to a power control unit such as an UPS, turn it on.
2. Open the front door and press the POWER switch. The POWER/SLEEP lamp on the front of the server lights
up.
NOTES:
 Connect the power cord and wait at least 10 seconds before pressing the POWER
switch. The Status lamp lights amber immediately after the power cord is connected or
AC power supplied to the server. Wait until the lamp goes off, and press the POWER
switch.
 Do not power off the server before some characters have appeared on the screen.
The POWER/SLEEP lamp on the front of the server lights up.
After a few seconds, a full screen logo appears on the screen and the Power On Self-Test (POST) begins. The
POST runs automatically when you power on the server or reset it with a keyboard operation (Ctrl + Alt +
Delete). The POST runs diagnostics, initializes the server, sets the interrupt vectors, detects any installed
peripheral devices, and boots the operating system (if installed). See Chapter 2 for a detailed description of
the POST.
If the server halts before completing the POST, the POST emits a beep code indicating a fatal system error
requiring immediate attention. (See Chapter 8, "Troubleshooting," for troubleshooting information.)
During the memory test, the POST displays the amount of memory it was able to access and test. Depending
on the amount of installed memory, it may take several minutes to complete the memory test.
NOTE: The factory-set is defined to hide the POST screen with a full logo. You can
always switch to the POST screen by pressing Esc. To change the start-up screen, use the
BIOS setup utility, "SETUP." (See Chapter 4 for details.)
During the POST, you will see banner messages prompting you to launch the BIOS SETUP utility stored in
the ROM of the motherboard or on an installed option board.
Start the BIOS SETUP utility appropriate to your system environment to change the BIOS setup. For the
BIOS SETUP for the server, see Chapter 4. For the BIOS SETUP of the optional board, refer to the manual
that comes with the optional board.
IMPORTANT: Always allow the POST to complete before turning off your system.
