Introduction
The 9F241-12 MicroLAN  Module is a Dual Attached Concentrator module for
the SmartSwitch 9000 (see Figure 1-1). The 9F241-12 provides twelve multimode
fiber Master ports allowing the connection of Single or Dual Attached Stations.
The 9F241-12 is ANSI FDDI-compliant with SMT (version 7.3), MAC, PHY, and
PMD. This module attaches directly to the SmartSwitch 9000 FNB backplane,
delivering up to 400 Mbps of bandwidth. The 9F241-12 module uses the Intel i960
microprocessor for all SMT and local/remote SNMP management functions.
Features
Processor
The 9F241-12 is 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
• FDDI Bandwidth Utilization Statistics
Connectivity
The front panel Master port connections are via standard multimode fiber
SC-type connectors. Multiple modules can be combined to provide connections
for up to 168 FDDI stations. All FDDI stations connected to the Master ports are
directly attached to the FNB backplane. These ports are not bridged or routed to
the FNB backplane.

Introduction

Management Information Base (MIB) Support
The 9F241-12 provides MIB support, including the following:
• IETF FDDI MIB
• IETF MIB II
• a host of Cabletron Enterprise MIBs.
LANVIEW LEDs
The 9F241-12 uses LANVIEW, the Cabletron Systems built-in visual diagnostic
and status monitoring system. With LANVIEW LEDs, you can quickly identify
the device, port, and physical layer status at a glance.
Hot Swapping
The 9F241-12 can be installed or removed from the chassis while the SmartSwitch
9000 is powered up, without affecting the operation of the rest of the network.
For a complete list of supported MIBs, refer to the release notes provided in the
concentrator modules package.
