Driver Installation Summary for Experienced Users 3-5
■ In a two-NIC scenario, when NIC 1 is active and NIC 2 is standby,
and if the link on the NIC 1 port fails, NIC 2 assumes the
configuration profile of NIC 1 and becomes the active NIC.
NIC 1 now becomes a standby NIC for NIC 2.
■ When a standby NIC assigned to multiple active NICs becomes
active, it can no longer be a standby NIC for its other designated
active NICs.
■ When an active NIC with multiple standby NICs fails, the first
eligible standby NIC (in driver load order) assumes the
configuration profile of the active NIC. If this NIC in turn fails,
the next designated standby NIC (in driver load order) takes
over, and so on.
■ A NIC cannot be configured as a standby NIC for another
standby NIC.
■ A resilient server link is established only if the active NIC is
operational after Windows NT is booted.
The standby NIC cannot assume the configuration profile of
an active NIC that has never been operational.
Driver Installation Summary for Experienced Users
Experienced Windows NT users knowledgeable in ATM

Before You Begin
■ Verify that all system and memory requirements are met.
■ When multiple ATMLink NICs are installed, run the
ATMLink diagnostic utility.
Write down the MAC address, the bus number, and the slot
