Introduction
The 9F120-08, 9F122-12 and 9F125-08 MicroLAN™ Modules are Dual Attached
Concentrator modules for the SmartSwitch 9000 (see Figure 1-1). The 9F120-08
provides eight multi-mode fiber Master ports, the 9F122-12 provides twelve
unshielded twisted pair Master ports, and the 9F125-08 provides eight single
mode fiber Master ports. All allow connections of Single or Dual Attached
Stations. The 9F120-08, 9F122-12 and 9F125-08 are ANSI FDDI-compliant with
SMT (version 7.3), MAC, PHY, and PMD. These modules attach directly to the
SmartSwitch 9000 FNB backplane, delivering up to 400 Mbps of bandwidth. The
modules use the Intel i960 microprocessor for all SMT and local/remote SNMP
management functions.
Features
Processor
The concentrator modules are equipped with an advanced Intel i960
microprocessor. This microprocessor provides a platform for all management
functions within a scalable RISC-based architecture.
Management
Management features include the following:
• Module insert/bypass control
• MAC placement
• MAC level and network level statistics
• An FDDI station list
• Individual Master port assignments
