3-4 CHAPTER 3: WINDOWS NT DRIVER INSTALLATION

NIC Information Requirements

Names of the ELANs to be configured on each ATMLink NIC

IP address and subnet mask of each ELAN using TCP/IP if a DHCP server is not being used

ATM address of the LES or LECS (other than the ATM Forum Well-known Address) if ILMI services are not used

PCI slot number of each installed ATMLink NIC

The MAC address and PCI slot numbers of installed 3Com ATMLink NICs are used in the Windows NT driver installation. They can be obtained by using the diagnostic utility (see Chapter 6 for details).

Resilient Server Links Overview

Resilient server links add redundant function to your server to protect against network disruption and data loss.

To use resilient links, you must install two or more 3Com ATMLink NICs in your system. During the network driver configuration procedure, at least one NIC must be designated an active NIC. The standby NIC takes over when the link on a designated active NIC port is lost.

Rules for Using Resilient Server Links

Resilient server links are established only among ATMLink NICs installed in the same computer.

To make a resilient server link, at least two ATMLink NICs must be installed in the same computer, and one of the NICs must be an active NIC.

Active NICs and their standby NICs must be connected to switches on the same ATM network.

Up to three standby NICs can be assigned to a single active NIC.

A single standby NIC can be assigned to as many as three active NICs.
