Introduction
The 9H423-28 (Figure 1-1) is a switching module with twenty-four 10 Mbps
Ethernet ports and four 100 Mbs Fast Ethernet ports. The module is configured
with two RJ21 connectors, two RJ45 connectors, two ST fiber connectors and a slot
for an FEPIM. The two RJ21 connectors provide twenty-four 10 Mbps Ethernet
ports. The RJ45 connectors, ST connectors and FEPIM (the module supports either
the FE-100TX or the FE-100FX) provide the four 100 Mbps Ethernet ports. The two
ST connectors represent a single port, as one connector is for transmit and one is
for receive. Each module also provides an additional port that connects directly to
the Internal Network Bus (INB) backplane interface. This module uses 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.
This module can operate in two modes: either as a 28-port Ethernet traditional
switch (using 802.1d standards) with a high speed backbone connection, or as a
Secure Fast Switch (SFS) with 28 Ethernet connections. Each port can be
configured to operate in the Full Duplex mode. This configuration allows each
10BASE-T port to provide a full 20 Mbps of bandwidth and the 100BASE-T ports
to provide 200 Mbps of bandwidth. The fiber ports on this module operate only in
Full Duplex mode.
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 9H423-28 also features 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 9H423-28 module is 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 9H423-28 module incorporates 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 9H423-28 features 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 a wide variety of statistical network management
information to enhance network planning and troubleshooting. The 9H423-28
provides information for each front panel Ethernet 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 9H423-28 module has one interface to the INB and 28 front port connections.
The INB interface is a fixed connection to INB-B that allows the module to
communicate with other SmartSwitch 9000 modules supporting various LAN
technologies including: Token Ring, FDDI, Ethernet, WAN, Fast Ethernet and
ATM. The module is configured with two RJ21 connectors, two RJ45 connectors,
two ST fiber connectors and a slot for an FEPIM. The two RJ21 connectors provide
twenty-four 10 Mbps Ethernet ports, and the RJ45 connectors, ST connectors and
FEPIM (the module supports either the FE-100TX or the FE-100FX) provide four
100 Mbps Ethernet ports. The multimode ST connectors provide a 100BASE-FL
connection, with links up to 2000 meters in length.
Auto-negotiation
The auto-negotiation feature (available only with the 100BASE-T RJ45 ports )
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

1-3
Introduction
negotiate duplex, both the 9H423-28 and the attached device must be configured
for auto-negotiation. If only the 9H423-28 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.
Standard Ethernet/Full Duplex Operation
The 9H423-28 module supports both 100BASE and 10BASE technology. This
allows each port on the module to be configured, through local and or remote
management (SNMP), to operate in standard Ethernet mode (simplex) or full
duplex mode. Operating in standard Ethernet mode limits bandwidth to 10
Mbps/100Mbps per port, while operating in duplex mode doubles bandwidth
from 10 Mbps/100Mbps to 20 Mbps/200 Mbps per port.
Management Information Base (MIB) Support
The 9H423-28 module provides MIB support including:
• RMON (RFC-1271)
• IETF MIB II (RFC-1213)
• IETF Bridge MIB (RFC-1493)
and a host of other Cabletron Enterprise MIBs.
INB
The 9H423-28 module attaches to INB-B of the SmartSwitch 9000 Backplane. The
INB Backplane is designed to transport fixed length data blocks between modules
in the SmartSwitch 9000 using an INB Time Division Multiplexing (ITDM) design.
The SmartSwitch 9000 INB bus delivers 2.5 Gbps of true data bandwidth with all
control and management communication being serviced on the 8-bit out-of-band
bus. The time slices of the INB manager operates in all three modes at once,
without user intervention.
All RJ45 connections are capable of auto-negotiation, and can operate at 10 Mbps
or 100 Mbps, full or half duplex. Fiber connections can only operate at the 100
Mbps rate, full or half duplex.
NOTE
For a complete list of supported MIBs, refer to the release notes provided with the
9H423-28.
NOTE

Introduction
1-4
Arbitration for the backplane is accomplished in the INB Time Division
Multiplexing (ITDM) logic. The arbitration is a three-level scheme that ensures
that no one can get the backplane for more than one time slice at a time.
The ITDM RAM contains 256 4-bit locations. This RAM is used to hold slot
numbers of modules participating in INB backplane arbitration. The arbitration
engine accesses this RAM once every time slice to get a slot number. That slot
number will be granted access on the next time slice if it is requesting. The
arbitration engine is always one time slice ahead, meaning that the value read
from the RAM is for the next time slice, not the current time slice.
LANVIEW LEDs
The 9H423-28 module uses LANVIEW – the Cabletron Systems built-in visual
diagnostic and status monitoring system. With LANVIEW LEDs, you can quickly
identify, at a glance, system status as well as the device, port, and physical layer
status. Two LEDs indicate the transmission and reception of data from the INB
SmartSwitch 9000 backplane connection. Each of the 12 Ethernet front panel ports
features two LEDs per port to indicate the port’s Administrative status (enabled/
disabled), LINK status (Link/Nolink), and Data Activity (receiving and
transmitting data).
