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.

Chapter 1

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

1-1

Introduction

Connectivity

The front panel Master port connections are via standard fiber FDDI MIC
connectors or RJ-45 Unshielded Twisted Pair ports. Multiple modules can
combine 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.

Management Information Base (MIB) Support

Both concentrator modules provide MIB support including the following:

• IETF FDDI MIB

• IETF MIB II

• a host of Cabletron Enterprise MIBs.

NOTE

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

LANVIEW LEDs

The concentrator modules use 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 concentrator modules 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 Modules

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

1. Remove the blank panel, covering the slot in which the MicroLAN Module
will be installed. All other slots must remain cover ed to ensure proper airflow
and cooling.

2. Unpack the MicroLAN Module by carefully removing it from the shipping
box. (Save the box and packing materials in the event the module must be
reshipped.)

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 2-1.

4. Remove the MicroLAN Module from the plastic bag. (Save the bag in the
event the module must be reshipped.) Observe all precautions to prevent
damage from Electrostatic Discharge (ESD).

5. Examine the MicroLAN Module, carefully checking for damage. If any
damage exists, DO NOT install the module. Immediately contact Cabletron
Systems Technical Support.

6. Install the MicroLAN Module in the chassis by sliding it in any available slot
and locking down the top and bottom plastic tabs, as shown in Figure 2-1.
Take care that each module slides in straight and properly engages the
backplane connectors. When installing a module, ensure that the circuit card
is between the card guides, as shown in Figure 2-1. Check both the upper and
lower tracks.

The Reset Switch

The Reset switch is located on the front panel, under the top plastic tab, as shown
in Figure 2-2. 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 again for three seconds restarts the
module.

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

Operation

The MicroLAN Modules, as shown in Figure 3-1, provide 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 FDDI­compliant 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, through standard A/B port connections.

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 SMB-10 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,
which 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.

3-2

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.

Operation

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 modules have 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.

i960 Core

The i960 core provides the SNMP and SNMPv2 pr otocol stacks, as well as support
for industry standard MIBs. Additionally, Cabletron enterprise extension MIBs
are supported for each media type. Advanced management services, such as the
Distributed LAN Monitor, RMON, telnet and network address to MAC address
mapping, are also provided by the i960 core.
