Introduction

Chapter 1

The 9H421-12, 9H422-12 and the 9H429-12, shown in Figure 1-1, are Fast Ethernet
SmartSwitch

The 9H422-12 is a twelve port switch module, with eleven 10BASE-T/100BASE­TX ports and one FEPIM (Fast Ethernet Port Interface Module), on the front panel.
The FEPIM port accepts either the FE-100TX, for use with twisted pair copper, or
the FE-100FX, for use with mulitmode fiber optic cabling.

The 9H421-12 is a twelve port switch module, equipped with twelve 100BASE-FX
multimode fiber (MMF) ports.

The 9H429-12 is a twelve port switch module, equipped with twelve 100BASE-FX
single mode fiber (SMF) ports.

These modules connect to the SmartSwitch 9000 INB-2 backplane interface, and
employ the family of SmartSwitch ASICs, a high performance switch design, and
an Intel i960 microprocessor.

Features

Processor

The 9H421-12, 9H422-12, and the 9H429-12 are equipped with an advanced Intel
i960 microprocessor. This microprocessor provides a platform for all management
functions.

®

Modules for the SmartSwitch 9000.

Packet Switch Engine

These modules incorporate the family of SmartSwitch ASICs, a collection of
custom ASICs designed specifically for high speed switching. The SmartSwitch
ASIC bus is 64 bits wide with a bandwidth of 845 Mbps. Since all frame
translation, address lookups, and forwarding decisions are performed in
hardware, these modules can obtain a throughput performance of greater than
990K pps.

1-1

Introduction

Management

The 9H421-12, 9H422-12 and the 9H429-12 modules support SNMP for local and
remote management. Local management is provided through the RS-232 Com
ports on the SmartSwitch 9000 Environmental Module using a standard VT-220
terminal or emulator. Remote management is possible through Cabletron’s
SPECTRUM or any SNMP compliant management tool as well as telneting to the
module. Management features include module configuration and statistics. All
Fast Ethernet interfaces provide frames filtered, frames forwarded, and all
Spanning Tree Protocol parameters. All modules support RMON (RFC-1757),
IETF MIB II (RFC-1213), IETF BRIDGE MIB (RFC-1493), and a host of Cabletron
enterprise MIBs. In addition, the front panel provides LEDs for link status per
port as well as transmit and receive activity.

Connectivity

The 9H421-12, 9H422-12 and the 9H429-12 modules have one interface to the INB­2 and twelve front panel Fast Ethernet interfaces. The front panel connections for
the 9H422-12 are via eleven standard RJ45 connectors and one FEPIM.

Front panel connections for the 9H421-12 are via twelve standard multimode fiber
SC connectors, providing links up to 2000 meters in length, when operating in
half duplex (point to point) or full duplex. Distance of links on a shared LAN in
half duplex is 412 meters.

The 9H429-12 single mode SC connectors provide twelve Fast Ethernet 100BASE­FX connections, with links up to 10000 to 15000 meters in length, when operating
in half duplex (point to point) or full duplex. Distance of links on a shared LAN in
half duplex is 412 meters.

Auto-negotiation

The auto-negotiation feature (available only with the 9H422-12 module) allows
the module to automatically use the fastest rate supported by the device at the
other end (either 10 Mbps or 100 Mbps at either half or full duplex). To negotiate
duplex, both the 9H422-12 and the attached device must be configured for auto­negotiation. If only the 9H422-12 is configured for auto-negotiation, the module
will set the connection to half duplex at either the 10 Mbps or 100 Mbps rate. This
technology is similar to how modems negotiate transmission speed, finding the
highest transmission rate possible. Similarly, auto-negotiation determines the
highest common speed between two devices and communicates at that speed. If
no common speed is detected, the device will be partitioned.

All RJ45 connections are capable of auto-negotiation, and can operate at 10 Mbps

NOTE

or 100 Mbps, full or half duplex. Fiber connections can only operate at the 100
Mbps rate, full or half duplex.

1-2

Operation

The 9H422-12 is a twelve port switch module, with eleven 10BASE-T/100BASE­TX ports and one FEPIM (Fast Ethernet Port Interface Module), on the front panel.
The FEPIM port accepts either the FE-100TX, for use with twisted pair copper, or
the FE-100FX, for use with mulitmode fiber optic cabling. The 9H421-12 is a
twelve port switch module, equipped with twelve multimode fiber 100BASE-FX
ports. The 9H429-12 is a twelve port switch module, equipped with twelve single
mode fiber 100BASE-FX ports.

Chapter 3

The 9H422-12 is 10BASE-T and 100BASE-TX compatible and provides auto­negotiation for automatic speed selection. The 9H421-12 and 9H429-12 are
100BASE-FX compatible and operate only at 100 Mbps.

Each module can operate in either full duplex or half duplex mode. Auto­negotiation for 100BASE-T modules provides support for 10 Mbps and 100 Mbps
speeds at both half and full duplex. 100BASE-FX supports 100 Mbps speed at both
half and full duplex.

As shown in Figure 3-1, Fast Ethernet Network Interface Blocks (FENIBs) convert
data packets received from any of the front panel ports into a canonical frame
format before forwarding to the SmartSwitch ASIC, while the Internal Network
Bus Network Interface Block (INB NIB) converts data packets received from the
INB into a canonical format before forwarding to the SmartSwitch ASIC. The
FENIBs are each designed to handle traffic from two front panel ports.

All data packets destined for a front panel port, the INB, or the i960 are converted
into the canonical format before forwarding to the SmartSwitch ASIC. Network
Interface Blocks (NIBS) check for valid data packets entering the system. If an
errored data packet is found, the SmartSwitch ASIC flags the error and does not
forward the errored data packet to any outbound ports. Once in this common
format, the SmartSwitch ASIC decides from header information the port
destination of data packets. Data packets are then converted from the canonical
format to the proper format for the interface destination whether it is a front panel
port, or connection to the INB.

3-2

Figure 3-1. Packet Flow

FENIB

The Fast Ethernet Network Interface Block (FENIB) converts Ethernet data
packets received through front panel ports into a common canonical format that
allows the SmartSwitch ASIC Engine to determine the proper destination port.
The FENIB also converts data packets from the common canonical format back to
Ethernet data packets for transmission out front panel ports.

SmartSwitch ASIC

The SmartSwitch ASIC is a hardwar e based switch design that is the key building
block of the SmartSwitch 9000 hub. The SmartSwitch ASIC makes all filtering/
forwarding decisions in custom hardware as opposed to software like traditional
bridges. This custom hardware enables the SmartSwitch ASIC to process over
990K frames per second. The SmartSwitch ASIC is designed to support up to 64
ports shared between the host processor, the INB backplane, and LAN/WAN
interfaces on the front panel of SmartSwitch 9000 modules. The SmartSwitch
ASIC can operate in two modes; as a traditional switch
(SFS).

Operation

or as a SecureFast Switch

Traditional Switch

When operating as a traditional switch, the SmartSwitch ASIC makes filtering/
forwarding decisions based on Destination Address (DA), with standard IEEE

802.1d learning.

SecureFast Switch (SFS)

When operating as an SFS switch, the SmartSwitch ASIC makes all
filtering/forwarding decisions based on a Destination Address-Source Address
(DA-SA) pair and its receive port. These DA-SA pairs with the associated receive
port are programmed into the switch using Cabletron’s SecureFast Virtual
Network Server (SecureFast VLAN). This provides the network administrator
with the ultimate network security without the performance degradation found
when using routers or bridges with special filtering capabilities. The SmartSwitch
9000 hub can support individual modules operating in the traditional switch
mode or SFS mode providing security where needed.

3-3

Operation

i960 Core

The i960 core 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 telnet and network address
to MAC address mapping, are also provided by the i960 core.

The Host engine sends and receives packets via the CPU’s SmartSwitch ASIC
Interface. This allows the bridge to perform spanning tree protocol and other
bridging functions. The SMB Interfaces provide communication to the Host
Engine for management functions.

INB NIB

Each module that attaches to the Internal Network Bus (INB) has an INB Network
Interface Block (NIB). The INB NIB converts canonical frames to fixed length data
blocks for transmission onto the INB. For data blocks received from the INB, the
INB NIB reassembles the data blocks received from the INB back into canonical
frames for transmission to the SmartSwitch ASIC then from the SmartSwitch
ASIC to the front panel ports.

System Management Buses

There are two management channels within the SmartSwitch 9000 system: the
SMB-1 and the SMB-10. These buses provide side-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 which 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.

3-4

SMB-10 Bus

The SMB-10 is a 10 Mbps management bus located within the SmartSwitch 9000.
This bus is used for inter-chassis communication of modules as well as serving as
a side-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 side-band from user data. Modules which share the SMB-10 bus
periodically send out loop-back packets to ensure the validity of SMB-10. If 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 9H421-12, 9H422-12 and the 9H429-12 input
and output power parameters, keep watch over the main host processor, monitor
the temperature, and control the SMB LANVIEW diagnostic LEDs. Although the
system 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 environment module. The 9H421-12,
9H422-12 and the 9H429-12 are designed to continue functioning in the event of a
diagnostic controller fault.

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.

3-5

Operation

INB Interface

The INB Backplane is designed to transport fixed length data blocks between
modules in the SmartSwitch 9000 using a Time Division Multiplexing (TDM)
design. The SmartSwitch 9000 INB bus delivers 2.0 Gbps of true data bandwidth
with all control and management communication being serviced on the 8 bit out­of-band bus. The INB can time slice its bandwidth using one of three methods.
The default method is standard TDM round-robin bandwidth arbitration, the
second method is for modules to reserve a specific amount of bandwidth using
INB Manager, Cabletron’s INB Bandwidth Arbitrator, the third method permits
the lowest slot number to use any bandwidth not used by the previous two
methods.

FEPIM Specifications

The 9H422-12 SmartSwitch 9000 module uses a Fast Ethernet Interface Module
(FEPIM) to provide front panel cable connections. FEPIMs are user-installable.
See section titled

FE-100TX

The FE-100TX is an RJ45 connector supporting Unshielded Twisted Pair (UTP)
cabling.

The slide switch on the FE-100TX 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 FEPIM-100TX in both positions.
