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.

Chapter 1

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.

1-1

Introduction

NOTE

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.

For a complete list of supported MIBs, refer to the release notes provided in the
concentrator modules package.

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.

Installing the MicroLAN Module

This section describes how to unpack, configure and install the module into the
SmartSwitch 9000 chassis.

Unpacking the Module

1. Carefully remove the module from the shipping box. (Save the box and
packing materials in the event the module must be reshipped.)

2. Remove the module from the plastic bag. Observe all precautions to prevent
damage from Electrostatic Discharge (ESD).

3. Carefully examine the module, checking for damage. If any damage exists,
DO NOT install the module. Contact Cabletron Systems Technical Support
immediately.

User-Accessible Components

Figure 2-1 shows the various components that are accessible to the user. These
consist of an eight-position dip switch (explained in the next section), replaceable
PROMs and sockets for RAM. These will be used for future upgrades.
Instructions for installing the components will be supplied with the upgrade kit.

Installing the MicroLAN Module

Installing the Module into the SmartSwitch 9000
Chassis

SmartSwitch 9000 MicroLAN Modules can be installed in any of the 14 slots that
are available. To install, follow the steps below:

1. Switch off the power supplies and remove all power from the SmartSwitch
9000 chassis.

2. Remove the blank panels, covering the slots that the module is being mounted
in. All other slots must be covered, if modules are not being installed, to
ensure proper airflow and cooling.

3. Attach one end of the ESD wrist strap packaged with the SmartSwitch 9000
chassis to your wrist. Plug the other end into the ESD Wrist Strap Grounding
receptacle in the lower right corner of the SmartSwitch 9000 Chassis shown in
Figure 2-3.

4. Slide the module into a slot and lock down both the top and bottom plastic
tabs, as shown in Figure 2-3. Take care that the module slides in straight and
engages the backplane connectors properly.

The Reset Switch

The Reset switch is located on the front panel, under the top plastic tab, as shown
in Figure 2-4. It serves two functions:

• Pressing the Reset switch twice within three seconds causes the processor
(i960) to reset.

• Pressing and holding the switch on for three or more seconds causes the
module to shutdown. Pressing and holding it again for three seconds restarts
the module.

SNMP management may be used to disable this switch to enhance module
security.

Operation

The 9F241-12 module, as shown in Figure 3-1, provides concentrator ports that
connect directly to the FNB bus. Each port can connect to either ring (FNB-1 or
FNB-2). This is software configurable via local or remote management.

Flexible Network Bus (FNB)

The FNB consists of two dual FDDI networks, FNB-1 and FNB-2, providing up to
400 Mbps of data bandwidth. These FDDI networks are 100% ANSI
FDDI-compliant, supporting SMT (version 7.3), MAC, PHY, and PMD standards.
This allows the FNB to traverse multiple SmartSwitch 9000 hubs, or connect to
any ANSI FDDI-compliant device.

Operation

System Management Buses

There are two management channels within the SmartSwitch 9000 system: the
SMB-1 and the SMB-10. These buses provide out-of-band management and inter­module management communication.

SMB-1 Bus

The SMB-1 is a 1 Mbps management bus located within the SmartSwitch 9000.
This bus is utilized by all diagnostic controllers in the system including
connectivity modules, power supply modules and the environmental module.
The SMB-1 transports inter-chassis information between system components,
such as power and environmental information, as well as diagnostic messages.
Periodic loop-back tests are performed by all modules that share this bus to
ensure the validity of SMB-1. In the event a failure is detected on SMB-1, the SMB­10 may be used as an alternate communication channel.

SMB-10 Bus

The SMB-10 is a 10 Mbps management bus located within the SmartSwitch 9000
that is also used for inter-chassis communication of modules, as well as serving as
an out-of-band management channel into the SmartSwitch 9000. The SMB-10 is
externalized from the chassis via an optional Ethernet Port Interface Module
(EPIM) located on the front of the Environmental Module. Through an EPIM
connection, full SNMP management of the SmartSwitch 9000 is available out-of­band from user data. Modules that share the SMB-10 bus periodically send out
loop-back packets to ensure the validity of SMB-10. In the event a fault is detected
on the SMB-10, the SMB-1 can be used as an alternate communication channel by
the modules.

System Diagnostic Controller

This diagnostic controller is composed of a Z-80 microprocessor and its
supporting logic. The diagnostic controller is designed to control the power-up
sequencing of modules, monitor the concentrator modules input and output
power parameters, keep watch over the main host processor, as well as monitor
the temperature and control the SMB LANVIEW diagnostic LED. Although the
diagnostic controller and the main host processor can operate independently of
each other if needed, they exchange information about each others’ status and
overall module condition. The information gathered by the diagnostic controller
is available to the network manager via local/remote management and the LCD
located on the Environmental Module. The concentrator modules have been
designed so that in the event of a diagnostic controller fault, the concentrator
modules will continue to function.

3-2

DC/DC Converter

The DC/DC converter converts the 48 VDC on the system power bus to the
necessary operating voltages for its host network services module. The diagnostic
controller monitors and controls the operation of the DC/DC converter.

FNB Interface

SmartSwitch 9000 modules are designed with one of two attachment policies. One
allows dual attachment of a module to either FNB-1 or FNB-2; the second allows
dual attachment to both FNB-1 and FNB-2. The 9F241-12 module has a dual
attachment to the FNB backplane, connecting to both FNB-1 and FNB-2. The
module can insert into the FNB or bypass it. These flexible configuration options
make the SmartSwitch 9000 ideal for networks designed to Bridge/Route
multiple lower speed LANs to FDDI and/or networks designed using an FDDI
collapsed backbone.

Operation

i960 Core

The i960 core provides the SNMP protocol stacks, as well as support for industry­standard MIBs. Additionally, Cabletron enterprise-extension MIBs are supported
for each media type. Advanced management services, such as the Distributed
LAN Monitor, telnet and network address to MAC address mapping, are also
provided by the i960 core.
