System-error LED: This amber LED is on when a system error occurs. An LED on the diagnostic LED panel will also be on to further isolate the error. (For more information, see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD.)

Ethernet transmit/receive activity LED: When this green LED is on, there is activity between the server and the network.

Server power features

This section contains information about how to properly turn your server on and off.

Turning on the server

Turning on the server refers to the act of plugging the power cords of your server into the power source and starting the operating system.

You can turn on the server in any of the following ways:

vIf the power cords are connected to a power source, you can press the power-control button on the front of the server.

Notes:

1.You can install a circular disk over the power-control button to prevent accidental manual power-off. This disk, known as the power-control button shield, comes with your server.

2.After you plug the power cords of your server into the electrical outlets, wait approximately 20 seconds before pressing the power-control button. During this time, the system-management adapter is initializing; therefore, the power-control button does not respond.

vIf the server is turned on and a power failure occurs, the server will restart automatically when power is restored.

vIf ac power is present, the server is in Standby mode, and the server is connected to an ASM interconnect network that contains at least one system with an optional Remote Supervisor Adapter installed, the server can be turned on from the Remote Supervisor Adapter user interface.

vIf ac power is present, the server is in Standby mode, and an optional Remote Supervisor Adapter is installed in the server, the server can be turned on from the Remote Supervisor Adapter user interface.

vWhen you plug in your server for the first time, Wake on LAN can turn on the server.

vIf your server was previously turned on, it must be properly placed in Standby mode for the Wake on LAN feature to turn on the server.
