Input/output connectors
Ethernet Diagnostic LEDs:
Your server contains two diagnostic light-emitting diodes
(LEDs) on the Ethernet connector that is located at the rear of
the server.

When the green LED is on, it indicates that the Ethernet
controller is connected to a hub or switch and is receiving
link pulses. This LED is also known as the Link OK
light.

When the amber LED is on, it indicates that the Ethernet
network is operating at 100 Mbps. When this LED is off,

Input/output connectors
Input/output (I/O) connectors provide ports for transferring
information into and out of your server. You can connect a variety
of I/O devices to your server, including a monitor, keyboard,
mouse, and printer. For more information on the ports and their
specific technologies, see “Connecting external options” on
page 133.
At the rear of your server is a panel that provides access to I/O
connectors. Adapters installed in expansion slots might also
provide I/O connectors. The following illustration shows the I/O
connectors that come with your server.
