Ethernet Connector: An unshielded, twisted-pair (UTP) cable with an RJ-45 connector attaches here to the 10/100 Ethernet controller on the system board. For information on the Ethernet controller, see "Configuring the Ethernet controller" on page 38. For more information on the Ethernet connector, see "Ethernet connector" on page 159. For information on cables, see "Specifications (Ethernet cable)" on page 53. The server contains diagnostic light-emitting diodes (LEDs) for the Ethernet connector located on the rear panel 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. Parallel Connector: A signal cable for a parallel device, such as a printer, connects here. Universal Serial Bus (USB) Connectors: I/O devices with universal serial bus (USB) connectors attach to USB connector 1 and connector 2. You need a 4-pin cable to connect a device to these ports. Serial Connectors: Signal cables for modems or other serial devices attach to the 9-pin serial connectors of serial ports 1 and 2. See "Serial port connectors" on page 89 for port assignment information. Mouse Connector: The mouse cable connects here. This connector is sometimes called the auxiliary-device port. Keyboard Connector: The keyboard cable connects here. Monitor Connector: The monitor signal cable connects here. 96 Netfinity Server HMM
