Ethernet connectorsThe following illustration shows an Ethernet connector.8 1Connect a Category 3, 4, or 5 unshielded twisted-pair cable to this connector.100BASE-TX and 1000BASE-T Fast Ethernet standards require Category 5 orhigher cabling.The server has three Ethernet connectors. Two of the Ethernet connectors areattached to the Ethernet controllers. See the User’s Guide on the IBM xSeriesDocumentation CD for more information about the Ethernet controllers.To enable remote server management through a network, use the RemoteSupervisor Adapter II SlimLine Ethernet connector. This connector is active only ifan optional Remote Supervisor Adapter II SlimLine is installed. See thedocumentation that comes with the option for more information.Advanced Systems Management (ASM) connectorsUse either of these dual RJ-45 connectors to connect the server to an IntegratedxSeries Adapter (IXA) that is installed in the server.Keyboard connectorUse this connector to connect a PS/2 (non-USB) keyboard to the server. Thefollowing illustration shows a keyboard connector.642 135If you attach a keyboard to this connector, USB ports and devices are disabledduring POST.Serial connectorUse a serial connector to connect a serial device. The following illustration shows aserial connector.1 56 9Ultra320 SCSI controller system-board connectorsThe integrated dual channel small computer system interface (SCSI) controller withintegrated RAID supports two independent Ultra320 SCSI channels: one externaland one internal. Each channel supports up to 15 SCSI devices. You can use theexternal LVD SCSI channel connector on the rear of the server to connect differenttypes of SCSI devices, such as drives or printers.
