USB technology provides up to 12 megabits-per-second (Mbps) speed with a
maximum of 127 external devices and a maximum signal distance of five meters (16
ft.) per segment.
USB-port connectors
Each USB port has an external connector on the rear of the server for attaching USB
compatible devices.
The following table shows the pin-number assignments for the USB-port connectors
on the rear of your server.
Ethernet port
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
(FDX) capability, which enables simultaneous transmission and reception of data on
the Ethernet local area network (LAN).
To access the Ethernet port, connect a Category 3, 4 or 5 unshielded twisted-pair
(UTP) cable to the RJ-45 connector on the rear of your server.
Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the
network be Category 5 or higher.
The Ethernet (RJ-45) connector has two lights. The Ethernet link-status light is on the
left. When this green light is on, there is an active connection on the Ethernet port.
The Ethernet transmit/receive activity light on the right. When this amber light is on,
there is activity between the server and the network. These lights have the same
functions as the Ethernet link-status light and the Ethernet transmit/receive activity
light on the information panel (see “Information panel” on page 8).
Configuring the Ethernet controller
When you connect your server to the network, the Ethernet controller automatically
detects the data-transfer rate (10Mbps or 100Mbps) on the network and then sets the
controller to operate at the appropriate rate. 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 full duplex (FDX). The
controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.
The Ethernet controller is a PCI Plug and Play device. 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.
