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, it indicates that the Ethernet network is operating at 10 Mbps. For additional information, see "Diagnostic LEDs" on page 218. CD-ROM Drive In-Use Light: This light comes on when the CD-ROM drive is accessed. Diskette Drive In-Use Light: This light comes on when the diskette drive is accessed. 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. Chapter 1.
