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).  
®
Each 9E106-06 is equipped with two advanced Intel i960 RISC microprocessors.  
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.  
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).  
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  
SmartSwitch 9000 is powered up without affecting the operation of the remaining  
modules in the chassis.

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 inter-  
module 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-of-  
band 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.

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 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.  
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.

Appendix A  
EPIMs  
The 9E106-06 Ethernet Switching Module provides one port per channel for  
Cabletron Systems EPIMs. EPIMs allow connecting to the 9E106-06 using  
different media types. Cabletron Systems offers a variety of EPIMs whose  
specifications are explained in the following sections.  
NOTE  
Verify that the EPIM is the proper revision before installing it. See Installing the  
EPIM on page 2-4 for details.  
EPIM-T  
The EPIM-T is an RJ-45 connector supporting UTP cabling. It has an internal  
Cabletron Systems TPT-T™ 10BASE-T Twisted Pair Transceiver.  
The slide switch on the EPIM-T determines the crossover status of the cable pairs.  
If the switch is on the X side, the pairs are internally crossed over. If the switch is  
on the = side, the pairs are not internally crossed over. Figure A-1 shows the  
pinouts for the EPIM-T in both crossover positions.  
The link distance is up to 100 meters on unshielded twisted pair cable as specified  
by ANSI TP-PMD.

The transmitter power levels and receive sensitivity levels listed are Peak Power  
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).  
NOTE  
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  
The link distance is up to 40 kilometers (max) and 25 kilometers (typical) on  
single mode fiber-optic cable as specified by ANSI SMF-PMD.

EPIMs  
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  
25°C is -16.4 dBm. For a 4°C temperature increase, multiply the typical  
coefficient (-0.15 dBm) by four and add the result to typical output power (4 x -  
0.15 dBm + -16.4 = -17.0).

The transmitter power levels given above are Peak Power Levels after optical  
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).  
NOTE  
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.

EPIM-A and EPIM-X (AUI Port)  
The link distance is up to 185 meters on the thin-net coaxial cables.  
Internal Termination Switch  
= On (internally terminated)  
= Off (need external termination)  
Figure A-4. EPIM-C  
Connector Type  
This connector type is a BNC receptacle, with gold center contact, for use with  
BNC type tee-connectors and RG-58 thin-net cable.  
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.
