Introduction
The 9E106-06 is a multi-port Ethernet Switch Module for the SmartSwitch 9000
that provides high speed IEEE 802.1D compliant bridging and SecureFast™
Switching (SFS).
Chapter 1
®
Each 9E106-06 is equipped with two advanced Intel i960
One processor provides the module’s SNMP protocol stack for both IETF and
Enterprise MIB extensions. Additional higher-level management services such as
RMON and Distributed LAN Monitor (DLM) are also provided. The other
processor acts as the primary switching device, continually directing network
traffic to the appropriate destination interface.
The 9E106-06 module provides six user configurable front panel Ethernet Port
Interfaces Module (EPIM) connections and one backplane connection to the
SmartSwitch 9000 Flexible Network Bus (FNB). The FNB is a dual FDDI
backplane channel that allows for reliable, high-capacity communications
between all FNB modules. Users on all six Ethernet segments can access the hub’s
Flexible Network Bus (FNB) and communicate with users on any other FNB
based Ethernet, Token Ring, FDDI, ATM or WAN module. Since each FNB
module translates its native user’s data packets to FDDI frames, all modules can
communicate without the use of any external or additional bridge or router
components.
Each EPIM Port is a single network segment that can operate in one of two ways:
as a host to a single user or as a host to multiple users through another multiport
switch, bridge, or repeater device. Ethernet networks are connected to the
9E106-06 using standard Cabletron EPIMs.
RISC microprocessors.
The 9E106-06 also features front panel LANVIEW™ Diagnostic LEDs to offer
at-a-glance status information about each front panel port, as well as the
operation of the overall module.

Introduction
Features
Processors
The 9E106-06 is equipped with dual advanced Intel i960
®
RISC microprocessors.
One processor provides a platform for all management applications, such as
Spanning Tree, RMON, IETF and Enterprise MIB support. This network
management information is available through a variety of methods. All SNMP
based information is accessible either via an in-band (front panel port), side-band
(SMB-10), or out-of-band via the Environmental Module’s (EM) COM ports. For
more information on the EM’s COM ports or SMB-10 refer to the SmartSwitch
9000 Local Management User’s Guide. The other processor acts as the primary
switching device. This switching device can operate in two modes, as a traditional
bridge, or as a SecureFast Switch (SFS).
System Management
The 9E106-06 provides interfaces to the two System Management Buses (SMB-1
and SMB-10) for intermodule management. The SMB-1 Bus is only accessible to
modules. The SMB-10 Bus is accessible through the EPIM on the front of the
Environmental Module.
Management
The 9E106-06 provides local and remote management functions. Local
management is provided through the RS-232 COM ports on the SmartSwitch 9000
Environmental Module using a standard VT-220 terminal or equivalent, Serial
Line Interface Protocol (SLIP), or Point-to-Point Protocol (PPP).
1-2
Remote management is possible through Cabletron’s SPECTRUM or any SNMP
compliant management tool. Included as management features are the IETF
Standard Management Information Base (MIBs) RMON (RFC 1271), IETF MIB ll
(RFC 1213), IETF Bridge MIB (RFC 1493), FDDI 1512 with SMT 7.3 and a host of
other Cabletron enterprise MIBs. In addition, the front panel provides LEDs to
indicate LINK status per port, as well as transmit and receive activity.
Connectivity
The 9E106-06 module has six user configurable front panel Ethernet Port Interface
Module (EPIM) connections and one Flexible Network Bus (FNB) backplane
connection. Ethernet networks connect to the 9E106-06 module using standard
Cabletron EPIMs. EPIMs presently available include:
• EPIM-C For Thin-net Coaxial
• EPIM-T For 10Base-T Twisted Pair
• EPIM-F1/EPIM-F2 For Multimode Fiber Optic
• EPIM-F3 For Single Mode Fiber Optic
• EPIM-A For AUI Cable segment
• EPIM-X For AUI Cable segment
Introduction
The FNB backplane connection is a fixed connection to FNB-1 or FNB-2. This
connection allows the 9E106-06 to communicate with other SmartSwitch 9000
modules supporting various LAN technologies including: Token Ring, FDDI,
Ethernet, WAN and ATM.
Bridging/SecureFast™ Switching
9E106-06 operates in two modes, as a traditional bridge, or as a SecureFast Switch.
In the traditional bridge mode, the 9E106-06 makes filtering/forwarding
decisions based on frame destination address. In the SecureFast Switch mode,
filtering/forwarding decisions are made based on both frame destination and
source addresses.
Management Information Base (MIB) Support
The 9E106-06 provides MIB support including:
• RMON (RFC 1271)
• IETF MIB II (RFC 1213)
• IETF Bridge MIB (RFC 1493)
• FDDI 1512 with SMT 7.3 and a host of other Cabletron Enterprise MIBs.
NOTE
For a complete list of supported MIBs, refer to the release notes provided in the
9E106-06 package.
LANVIEW LEDs
The 9E106-06 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 9E106-06 can be installed or removed from the chassis while the

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 1Mbs 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 10Mbs 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 which 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 the
supporting logic. The diagnostic controller is designed to control the power-up
sequencing of modules, monitor the 9E106-06 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 9E106-06 has been designed so that in
the event of a diagnostic controller fault, the 9E106-06 continues 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 9E106-06 has one dual attachment
to the FNB backplane, connecting to either FNB-1 or FNB-2. The module can
insert into either the FNB-1 or FNB-2, or bypass both. 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 a FDDI
collapsed backbone.
Operation
i960 Switch
The i960 Switch Processor is the first of the dual i960 RISC microprocessors built
into the 9E106-06 Module. This processor provides the packet forwarding logic
and can be configured to run as a layer two bridge, or as a SecureFast switch.
i960 Host
The i960 Host Processor is the second of the dual i960 RISC microprocessors built
into the 9E106-06 Module. This processor provides the SNMP protocol stacks to
support industry standard 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 provided by this i960 processor.

has an internal Cabletron Systems FOT-F™ Fiber Optic Transceiver. The EPIM-F1
is equipped with SMA Connectors and the EPIM-F2 is equipped with ST
Connectors. Figure A-2 shows both EPIMs. Specifications for the EPIMs are listed
in Table A-1.
The link distance is up to 2 kilometers on the multimode fiber-optic cable as
specified by ANSI MMF-PMD.

Levels after optical overshoot. A Peak Power Meter must be used to correctly
compare the values given above to those measured on any particular port. If
Power Levels are being measured with an Average Power Meter, then 3 dBm must
be added to the measurement to correctly compare those measured values to the
values listed (i.e., -30.5 dBm peak = -33.5 dBm average).
EPIM-F3
The EPIM-F3 supports Single Mode Fiber Optic cabling. It has an internal
Cabletron Systems FOT-F™ Fiber Optic Transceiver and is equipped with ST
Connectors. Figure A-3 shows the EPIM-F3. Specifications for the EPIM-F3 are
listed in Table A-3.

NOTE
Transmitter Power decreases as temperatures rise and increases as temperatures
fall. Use the Output Power Coefficient to calculate increased or decreased power
output for your operating environment. For example, the typical power output at
°
C is -16.4 dBm. For a 4°C temperature increase, multiply the typical
25
coefficient (-0.15 dBm) by four and add the result to typical output power (4 x -
0.15 dBm + -16.4 = -17.0).

overshoot. You must use a Peak Power Meter to correctly compare the values
given above to those measured on any particular port. If you are measuring power
levels with an Average Power Meter, add 3 dBm to the average power
measurement to correctly compare the average power values measured to the
values listed above (i.e., -33.5 dBm average + 3 dB = -30.5 dBm peak).
EPIM-C
The EPIM-C supports thin-net coaxial cabling and is equipped with an internal
Cabletron Systems TMS-3™ Transceiver. You can use the TERM switch on the
front of the EPIM-C to set the internal 50-ohm terminator. This eliminates the
need to connect the port to a tee-connector and terminator. Figure A-4 shows the
setting for the terminator switch.

Grounding
For safety reasons, only one end of a thin-net segment should be connected to
earth ground. Connection to earth ground at more than one point on the segment
may cause dangerous ground currents.
The BNC port of the Coaxial Interface Modules is not connected to earth ground.
EPIM-A and EPIM-X (AUI Port)
The EPIM-A is a DB-15 female connector used to attach segments to an external
transceiver. The EPIM-X is equipped with dual internal transceivers. It has a DB15
male connector used to attach segments to an AUI cable. Figure A-5 shows both
modules.
The AUI Cable must not exceed 50 meters in length. If 28 AWG thin office drop
AUI cable is used, then the maximum cable length is limited to 15.24 meters.
