Select the serial connector; then, use the arrow keys to advance through the available settings. 5. Press Esc twice to return to the Configuration/Setup Utility main menu; then, select Save & Exit Setup to exit from the Configuration/Setup Utility main menu. Serial connectors: There are two 9-pin, male D-shell serial connectors on the rear of your server, see "I/O connector locations" on page 72 for the location of these connectors.

This controller provides an interface for connecting to 10-Mbps or 100-Mbps networks and provides full-duplex capability, which enables simultaneous transmission and reception of data on the Ethernet LAN. To access the Ethernet connector, connect a Category 3, 4, or 5 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the rear of your server. See "I/O connector locations" on page 72. Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the network be Category 5. Configuring the Ethernet controller: When you connect your server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps or 100 Mbps) on the network and then sets the controller to operate at the appropriate rate. In addition, if the Ethernet connector that your server is connected to supports Chapter 5. Installing options 77

(UTP)
cable
to
