AFT, ALB and IPSec functions
The Network Adapter that is mounted in the server as the standard
device has the adapter fault tolerance (AFT) function, adaptive
load balance (ALB) function and IP Security(IPSec) function.
Those functions can be utilized if an optional extension network
adapter is installed.
What are the AFT and ALB functions?
AFT (Adapter Fault Tolerance)
The AFT function is realized by the primary adapter and second-
ary adapter. Usually only the primary adapter operates, and the
secondary adapter automatically operates when there is some trou-
ble with the primary adapter.
ALB (Adaptive Load Balance)
The ALB function is realized by two to four network adapters.
When four network adapters are mounted, they provide a broad
transmission band of maximum 200 Mbps (100 Mbps × 2) by bal-
ancing transmission data flow. (The reception band width is 100
Mbps.)
The ALB function supports the AFT function.
For using the ALB function, it is needed to install a 100 Base-TX
switching hub.

Service Pack 6a or later is required for using on Windows NT 4.0.
