    This manual is for system administrators responsible for configuring, monitoring, and maintaining the Fast Network 100 (FN100). Much of the configuration of the FN100 needs to be done using an SNMP-based network management station. This manual contains the SNMP MIB variables you may need to configure, monitor, and manage your FN100.
