You must turn off the server before you connect or disconnect cables from the
server. Exception: in order to view the error LEDs inside the server, you must
leave the power cables connected to the power supplies.
See the documentation that comes with any external devices for additional cabling
instructions. It might be easier for you to route cables before you connect the
devices to the server.
Cable identifiers are printed on the cables that come with the server and optional
devices. Use these identifiers to connect the cables to the correct connectors.
If the server comes with an installed operating system, see the documentation that
comes with the operating system for additional cabling instructions.
Updating the server configuration
When you start the server for the first time after you add or remove an internal
device, external SAS device, or USB keyboard or mouse, you might receive a
message that the configuration has changed. The Server Configuration and Boot
Management program starts automatically so that you can save the new
configuration settings.
Some optional devices have device drivers that you must install. See the
documentation that comes with each optional device for information about installing
device drivers.
