Notes:

1.For troubleshooting information, see “Troubleshooting the 10/100 Mbps Ethernet Controller” on page 149.

2.The Ethernet controller supports the operating systems that your s supports. To find out which operating systems your server supports, following World Wide Web address:

If you	need additional Ethernet	connections,	you can install an Etherne
such as	an IBM 10/100 Ethernet adapter. Review your network-adapter
documentation for any additional		configuration	requirements.

Note: If you are installing an IBM 10/100 Ethernet adapter, be sure Ethernet controller diagnostics and record the Ethernet controller configuration information before you install the adapter.

Failover for Redundant Ethernet

Your Netfinity 5000 server has	an integrated	Ethernet	controller. The				I

controller, you can configure the serverfailoverto functionsupport. aYou can
configure either the integrated Ethernet controller			or	the	NIC	adapt
Ethernet controller. In failover	mode, if the	primary Ethernet controlle

link failure, all Ethernet traffic associated with it is switched to (secondary) controller. This switching occurs without any user interventi Applications with active sessions do not experience any data loss. Wh primary link is restored to an operational state, the Ethernet traffi switches back to the primary Ethernet controller.
