intervention. The controller supports half-duplex (HDX)

and full-duplex (FDX) modes at both speeds.

However, auto-negotiation works only if the hub or switch

at the other end of the network also supports

auto-negotiation. If the hub or switch does not support

auto-negotiation, the speed (10 Mbps or 100 Mbps) will still

be detected correctly, but half-duplex mode will always be

selected. A full-duplex switch that does not support

auto-negotiation will not attach to the Netfinity 3500 server

in full-duplex mode. In this case, if you want the network

to operate in full-duplex mode, you must manually override

the settings to obtain a full-duplex connection. Refer to the

Ethernet documentation for additional information.

Attention

 The 10BASE-T Ethernet and the 100BASE-TX

Fast Ethernet cabling in the network must be

Category 5 or higher to meet various standards,

including electromagnetic compatibility.

 You must install a device driver to enable the

operating system to address the Ethernet

controller. Use ServerGuide to install this device

driver. Refer to the ServerGuide package for

instructions on installing device drivers.

Fast Ethernet operates at a data rate of 100 Mbps; that is,

ten times faster than standard Ethernet. However, except

for the different operating speeds, Fast Ethernet and

standard Ethernet are structurally identical. Applications

and protocols that are currently installed on a standard

Ethernet system can be seamlessly migrated to a Fast

Ethernet system. (In a very small number of cases, minor

tuning might be required to adjust the application to the

faster response time of a Fast Ethernet system.) Because

of the equivalence of the two types of Ethernet, mixed

Ethernet and Fast Ethernet systems also can be designed

and implemented.

The bandwidth required at each workstation connected to

a server is generally far less than the bandwidth required

at the server. This is because the server might have to

handle the bandwidth of multiple workstations at the same

time. A cost-effective solution to the bandwidth

requirements of this type of system is a mixed Ethernet

and Fast Ethernet network. This mixed network consists

of standard Ethernet connections at the workstations and

Fast Ethernet connections at the servers.

The Ethernet controller is a PCI device, and is therefore, a

Plug and Play device. You do not have to set any jumpers

or configure the controller for the operating system before

you use the Ethernet controller.
