Introduction
The 9E428-12/36 and 9E429-12/36 (Figure 1-1) are switching modules that
provide either 12 or 36 ports, depending on the module. The 9E428-12/36 provide
Ethernet fiber-optic 10Base-FL connectivity via multimode ST (straight through)
connectors, while the 9E429-12/36 modules use single mode ST connectors. There
are two ST connectors for each port, one for transmit and one for receive. Each
module also provides an additional port that connects directly to the Internal
Network Bus (INB) backplane interface. These modules use a SmartSwitch ASIC
design and an advanced Intel i960
®
microprocessor. This microprocessor provides
a platform for all management functions within a scalable RISC-Based
Architecture.
These modules can operate in two modes: either as a 12/36 port Ethernet
traditional switch (using 802.1d standards) with a high speed backbone
connection, or as a Secure Fast Switch (SFS) with 12/36 Ethernet connections.
Each port can be configured to operate in the Full Duplex mode. This
configuration allows each port to provide a full 20 Mbps of bandwidth for file
servers or high-end, user-intensive work stations.
Network management information is available through a variety of methods. All
information based on Simple Network Management Protocol (SNMP) is
accessible either via an in-band (front panel port), Side Band (SMB-10), or via the
Environmental Module’s COM ports. Serial Line Internet Protocol (SLIP) or
Point-to-Point Protocol (PPP) is supported by the Environmental Module’s COM
ports. For more information on the SMB-10, SLIP or PPP, refer to the SmartSwitch
9000 Local Management User’s Guide.
The 9E428-12/36 and 9E429-12/36 also feature front panel LANVIEW™
Diagnostic LED’s to offer at-a-glance status information about each front panel
port, as well as the operation of the overall module.

Introduction

Features
Processor
The 9E428-12/36 and 9E429-12/36 modules are equipped with an advanced Intel
i960 microprocessor. This microprocessor provides a platform for all management
functions such as Spanning Tree, RMON, and MIB support, within a scalable
RISC-Based architecture.
Fast Packet Switching
The 9E428-12/36 and 9E429-12/36 modules incorporate a hardware based switch
design referred to as the SmartSwitch ASIC, a collection of custom ASICs
designed specifically for high speed switching. Because all frame translation,
address lookups, and forwarding decisions are performed in hardware, these
modules can obtain a throughput performance of greater than 750K pps.
Management
The 9E428-12/36 and 9E429-12/36 feature 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
TM
terminal or emulator. 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
(RFC1271), IETF MIB II (RFC-1213), IETF Bridge MIB (RFC-1493), and a host of
other Cabletron enterprise MIBs. These modules also offer you a wide variety of
statistical network management information to enhance network planning and
troubleshooting. The 9E428-12/36 and 9E429-12/36 provide information for each
front panel Ethernet 10BASE-FL port, including packet counts along with errored
frame information such as collisions, CRCs, and Giants, via a variety of industry
standard and private MIBS. Industry standard IEEE 802.1d bridging, including
Spanning Tree Algorithm, is supported.
Connectivity
The 9E428-12/36 and 9E429-12/36 modules have one interface to the INB and
either 12 or 36 front port ST connectors. The INB interface is a fixed connection to
INB-B that allows the 9E428 and 9E429 modules to communicate with other
SmartSwitch 9000 modules supporting various LAN technologies including:
Token Ring, FDDI, Ethernet, WAN and ATM. The 9E428-12/36 multimode ST
connectors provide 12 or 36 Ethernet 10BASE-FL connections, with links up to
2000 meters in length, when operating in half duplex. The 9E429-12/36 single
mode ST connectors provide 12 or 36 Ethernet 10BASE-FL connections, with links
up to 5000 meters in length, when operating in half duplex.
Standard Ethernet/Full Duplex Operation
The 9E428-12/36 and 9E429-12/36 modules support 10BASE-FL. The use of
10BASE-FL allows each port on the modules to be configured, through local and
or remote management (SNMP), to operate in standard Ethernet mode (simplex)
