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 60 for the location of these 
connectors. The table below shows the pin-assignments for the serial connectors. 
Ethernet connector
Your server comes with an integrated Ethernet controller. 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 60.
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 (10Mbps 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 
auto-negotiation, the Ethernet controller will set the appropriate duplex state. That is, 
the Ethernet controller will adjust to the network data rate, whether the data rate is 
standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX), half duplex (HDX), or 
FDX. The controller supports HDX and FDX modes at both speeds.
The Ethernet controller is integrated on the system board. You do not need to set any 
jumpers or configure the controller for your operating system before you use the 
Ethernet controller. However, you must install a device driver to enable your 
operating system to address the Ethernet controller. The device drivers are provided 
on the ServerGuide CDs.
