Attention: For proper cooling and airow, install the server cover before turning on the server. Operating
the server for extended periods of time (more than 30 minutes) with the cover removed might damage
server components.
To install the server cover, do the following:
1. Make sure that all cables, cards, and other components are installed and seated correctly and that
you have not left loose tools or parts inside the server. Also, make sure that all internal cables are
correctly routed.
2. Position the server cover on the chassis so that the rail guides on the bottom of the server cover engage
the rails. Then, slide the server cover to the front of the server until it snaps into position and is closed.
Then, tighten the two thumbscrews to secure the server cover.
Note: Although the server cover is secured by two thumbscrews, for safety consideration, be sure to
use a tool, for example a screw driver, to tighten the thumbscrews and always make sure that the
thumbscrews are securely installed. Also, do not over-tighten the thumbscrews.
Connecting the cables
Attention: To prevent damage to equipment, connect the power cords last.
If the server cables and connector panel have color-coded connections, match the color of the cable
end with the color of the connector. For example, match a blue cable end with a blue panel connector, a
red cable end with a red connector, and so on. See “Rear view” on page 30 for an illustration of the I/O
connectors on the rear of the server.
Turning on the server
When the server is connected to an ac power source but is not turned on, the operating system does not
run, and all core logic except for the service processor (the integrated management module) is shut down;
however, the server can respond to requests to the service processor, such as a remote request to turn on
the server. The power-on LED ashes to indicate that the server is connected to an ac power source but
is not turned on.
Approximately ve seconds after the server is connected to ac power, one or more fans might start running
to provide cooling while the server is connected to power and the power-on button LED ashes quickly.
Approximately one to three minutes after the server is connected to ac power, the power-control button
becomes active (the power-on LED ashes slowly), and one or more fans might start running to provide
cooling while the server is connected to power. Then, you can turn on the server by pressing the power
button.
Updating the server conguration
When you turn on the server for the rst time after you add or remove a device, you might receive a message
to notify you that the conguration has been changed. The Setup Utility program starts automatically so
that you can save the new conguration settings. For more information, see Chapter 7 “Conguring the
server” on page 143.
Some optional devices have device drivers that you must install. For information about installing device
drivers, see the documentation that comes with each device.
The server comes with at least one microprocessor. If more than one microprocessor is installed, the server
can operate as a symmetric multiprocessing (SMP) server. You might have to upgrade the operating system
to support SMP. For more information, see the operating-system documentation.
