Ethernet connectors
The following illustration shows an Ethernet connector.
8 1
Connect a Category 3, 4, or 5 unshielded twisted-pair cable to this connector.
100BASE-TX and 1000BASE-T Fast Ethernet standards require Category 5 or
higher cabling.
The server has three Ethernet connectors. Two of the Ethernet connectors are
attached to the Ethernet controllers. See the User’s Guide on the IBM xSeries
Documentation CD for more information about the Ethernet controllers.
To enable remote server management through a network, use the Remote
Supervisor Adapter II SlimLine Ethernet connector. This connector is active only if
an optional Remote Supervisor Adapter II SlimLine is installed. See the
documentation that comes with the option for more information.
Advanced Systems Management (ASM) connectors
Use either of these dual RJ-45 connectors to connect the server to an Integrated
xSeries Adapter (IXA) that is installed in the server.

integrated RAID supports two independent Ultra320 SCSI channels: one external
and one internal. Each channel supports up to 15 SCSI devices. You can use the
external LVD SCSI channel connector on the rear of the server to connect different
types of SCSI devices, such as drives or printers. This controller uses:
