Power-control button: Press this button to manually turn the server on or off. System error light: When this amber light is on, it indicates that a system error has occurred. An amber error light on the interior of the server, adjacent to the faulty component, will also be on to further isolate the error. (For more information, see "Diagnostics" on page 11.) Cover-release latch: Slide this lever to release the cover. Key lock: Use the key that comes with your server to unlock the over. Turning on the server Turning on the server refers to the act of plugging the power cord of your server into the power source and starting the operating system. After you plug the power cord of your server into the power supply and an electrical outlet, the server can start in any of the following ways: v You can press the power-control button on the front of the server to start the server. Note: After you plug the power cord of your server into an electrical outlet, wait approximately 20 seconds before pressing the power-control button. During this time, the system is initializing; therefore, the power-control button does not respond. v If the server is turned on and a power failure occurs, the server will start automatically when power is restored. v The Wake on LAN feature will turn on the server at the set time (when a Magic Packet is received), provided that all of the following conditions are met: - AC power is present. - The server is either off or shut down from an Advanced Configuration and Power Interface (ACPI) operating system. - The Wake on LAN feature is enabled in the Configuration/Setup Utility program. Notes: 1. For additional information on the Wake on LAN function, adapters, and cables, refer to the documentation that comes with the adapters. 2. See "Ethernet port" on page 74 for information on Ethernet controllers and adapters, and Wake on LAN PCI adapters. v If the IBM Remote Supervisor Adapter is installed in your server, the Remote Supervisor Adapter can turn on the server. v The server has an Automatic BIOS Recovery (ABR) feature which allows recovery from defective BIOS in some cases. v The server provides Automatic Server Restart (ASR) logic that supports restarting the system when there is an operating system hang. Notes: 1. you can install a circular disk over the power-control button to prevent accidental manual power-off. The disk, known as the power-control button shield, comes with your server. 2.

Note:
After you plug the power cord of your server into an electrical outlet,
wait approximately 20 seconds before pressing the power-control button.
During this time, the system is initializing; therefore, the power-control
button does not respond.
v
If the server is turned on and a power failure occurs, the server will start
automatically when power is restored.
v
The Wake on LAN feature will turn on the server at the set time (when a Magic
Packet is received), provided that all of the following conditions are met:
–
AC power is present.
–
The server is either off or shut down from an Advanced Configuration and
Power Interface (ACPI) operating system.
–
The Wake on LAN feature is enabled in the Configuration/Setup Utility
program.
Notes:
1.
For additional information on the Wake on LAN function, adapters, and
cables, refer to the documentation that comes with the adapters.
2.
See

on page 74 for information on Ethernet controllers and
adapters, and Wake on LAN PCI adapters.
v
If the IBM Remote Supervisor Adapter is installed in your server, the Remote
Supervisor Adapter can turn on the server.
v
The server has an Automatic BIOS Recovery (ABR) feature which allows
recovery from defective BIOS in some cases.
v
The server provides Automatic Server Restart (ASR) logic that supports
restarting the system when there is an operating system hang.
Notes:
1.
you can install a circular disk over the power-control button to prevent
accidental manual power-off. The disk, known as the power-control button
shield, comes with your server.
