SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
THE 9H539-24 MODULE USES CLASS 1 LASER TRANSCEIVERS.
READ THE FOLLOWING SAFETY INFORMATION BEFORE
INSTALLING OR OPERATING THESE MODULES.
The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for
maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment. Class 1 Laser transceivers comply with
the following safety standards:
•
•
•
21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).
IEC Publication 825 (International Electrotechnical Commission).
CENELEC EN 60825 (European Committee for Electrotechnical Standardization).
When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all three
standards. Class 1 levels of laser radiation are not considered hazardous.
SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
LASER RADIATION AND CONNECTORS
When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the fiber (under
-6
normal conditions) is -12.6 dBm or 55 x 10 watts.
Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance
from the optical port (under worst case conditions) is
-2
3
2
0.8 W cm or 8 x 10 W m sr-1.
Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard.
When viewing the output optical port, power must be removed from the network adapter.

Introduction
Cabletron Systems SmartSwitch 9000 chassis, providing 24 MT-RJ MMF ports.
The 9E531-24 can be used to connect individual 10 BASE-FL user devices and
servers.
Features
Connectivity
The 9H532-24 connects to Ethernet networks or workstations through the 24
MTRJ ports on the front panel. These ports are IEEE 802.1D and 802.3 10BASE-FL
compliant. The ports support Multimode fiber cables with attenuation of less than
or equal to 3.75 dB/ Km, when measured at a wavelength of 850 nm.
1-1
Introduction
Duplex Mode
Through Local Management, each port on the 9E531-24 can be configured to
support either full or half duplex mode of operation.
Runtime IP Address Discovery
This feature enables the modules to automatically accept an IP address from a
Boot Strap Protocol (BootP) server on the network into NVRAM without
requiring a user to enter an IP address through Local Management.
When the modules are connected to the network and powered up, Runtime IP
Address Discovery (RAD) checks the modules for an IP address. If one has not yet
been assigned (module and SmartSwitch 9000 chassis IP address set to 0.0.0.0),
RAD checks to see if any of the module interfaces have a link. If so, RAD sends
out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an
IP address from a RARP or BootP server on the network.
The RAD requests start at an interval of one per second. The interval then doubles
after every transmission until an interval of 300 seconds is reached. At this point,
the interval remains at 300 seconds. The RAD requests continue until an IP
address is received from a RARP or BootP server, or an IP address is entered using
Local Management.
SmartTrunk
SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’
terminology for load balancing or load sharing. SmartTrunk technology provides
an easy-to-implement mechanism to group, or aggregate, multiple links of any
technology together to scale the backbone bandwidth beyond the limitations of a
single link. All links are user-configurable so administrators can scale the
backbone bandwidth by adding SmartTrunk links. The benefits of SmartTrunking
include the following:
•
•
•
All purchased bandwidth is used.
Distributed, resilient links increase reliability and performance.
Multiple technologies are supported within a single trunk for maximum
flexibility.
For information on SmartTrunk configuration, refer to the
SmartTrunk User’s Guide.
NOTE
1-3
Introduction
Management
Management of the 9E531-24 module and SmartSwitch chassis and any optional
equipment is accomplished using the Local Management application or remote
SNMP management stations. Local Management is accessible through the RS232
COM port on the Environmental Module using a local VT100 terminal, or a
remote VT100 terminal via a modem connection, and in-band via a Telnet
connection. In-band remote management is possible through Webview or any
SNMP compliant Network Management Software.
Local Management provides the ability to manage the 9E531-24. Local
Management information for non-Ethernet HSIMs or VHSIMs is included in their
respective user’s guide. For details on how to get manuals, refer to the Related
Manuals section in the Introduction.
WebView
The 9E531-24 modules can be managed by Cabletron WebView, a browser-based
utility. There is no software to install as this management capability is built into
each module.
Remote Monitoring (RMON)
The 9E531-24 supports all nine Ethernet RMON groups. The Statistics, Alarms,
Events and History groups are enabled on all ports by default.
Cabletron Systems RMON Actions is a vendor-specific extension of RMON and
provides the ability to set an “Action” on any SNMP MIB variable. The Action can
be triggered by setting an RMON Event and/ or Alarm. An example of an Action
would be to turn off a MIB-2 interface if a broadcast threshold is crossed.
Broadcast Suppression
Broadcast Suppression enables a user to set a desired limit of receive broadcast
frames per port/ per second to be forwarded out the other ports on the module up
to the set limit. Any broadcast frames above this specified limit are dropped. In
the event that broadcast frames are being suppressed, multicast and unicast
frames continue to be switched.
Port Redirect Function
The Port Redirect function, also referred to as “Port Mirroring,” is a
troubleshooting tool used to map traffic from a single source port to a destination
port within the chassis. This feature allows all packets, including those with
errors, to be copied and sent to an analyzer or RMON probe. The analyzer or
RMON probe will see the data as if it is directly connected to the LAN segment of
the source port.
Flow Control
Flow Control is a method of managing the flow of frames between two devices. It
ensures that a transmitting device does not overwhelm a receiving device with
data. This enables the receiving device to communicate with the transmitting
1-4
Introduction
device, and to have it pause its transmission while the receiving device processes
the frames already received. Flow control can be enabled or disabled on a port-by-
port basis. Both devices must support the IEEE 802.3x standard for flow control to
work.
The 9E531-24 supports the following two types of flow control:
•
•
frame based 802.3x
back pressure
Frame based 802.3x flow control is supported on all Ethernet ports operating in
the full duplex mode.
Back pressure flow control is supported on all Ethernet ports operating in the
standard mode of operation.
802.1p Port Priority
The IEEE 802.1p standard is used to assign a default priority to the frames
received without priority information in their tag header, and to map prioritized
frames to the appropriate transmit queues.

Switching Options
The 9E531-24 provides IEEE Standard-based 802.1 switching or SecureFast
Switching Virtual Network Services. In the 802.1 mode (the default mode of
operation), the switch functions as an 802.1D switch. When VLANs are
configured, it operates as an 802.1Q switch.
1-5
Introduction
Standards Compatibility
The 9E531-24 is fully compliant with the IEEE 802.3, 802.3x, 802.1Q, and 802.1p
standards. The 9E531-24 provides IEEE 802.1D Spanning Tree Algorithm (STA)
support to enhance the overall reliability of the network and protect against
“loop” conditions. The 9E531-24 supports a wide variety of industry standard
MIBs including RFC 1573 (MIB II), RFC 1271 (RMON), RFC 1493 (Bridge MIB),
RFC 1354 (FIB MIB), and RFC 1190 (Path MTU Discovery). A full suite of
Cabletron Systems Enterprise MIBs provide a wide array of statistical information
to enhance troubleshooting.
For information about how to extract and compile individual MIBs, contact
Cabletron Systems.
GARP Switch Operation
Some or all ports on the switch may be activated to operate under the Generic
Attribute Registration Protocol (GARP) applications, GARP VLAN Registration
Protocol (GVRP) and/ or GARP Multicast Registration Protocol (GMRP).
GARP is a protocol, or set of rules, that outlines a mechanism for propagating the
port state and/ or user information throughout a bridged LAN to keep track of
users and VLANs on the network fabric. MAC bridges and end users alike can
take part in the registration and de-registration of GARP attributes such as VLAN
and multicast group membership.
LANVIEW Diagnostic LEDs
LANVIEW diagnostic LEDs serve as an important troubleshooting aid by
providing an easy way to observe the status of individual ports and overall
network operations.
Year 2000 Compliance
The 9E531-24 module and the SmartSwitch 9000 chassis have an internal clock
that can maintain the time and date beyond the year 1999.

Installing the SmartSwitch 9000 Module
Using DIP Switch 6
The purpose of DIP switch 6 is to force a Flash download from a BootP server
through the EM-EPIM. The first step in this process is to configure the BootP
server. Configurations of BootP servers can differ from platform to platform and
from one operating system to another. Read the user’s manual on BootP and
TFTP serving for the correct files to edit and the correct files to execute for the
server. After configuration of the BootP server the module can then have the
switch state changed on dip switch 6 to initiate BootP and TFTP requests.
When the state of dip switch 6 is changed, the module begins requesting a BootP
server in an attempt to receive a Flash image download. The modules boot PROM
initiates a BootP sequence. During this sequence, the module requests an IP
address and a filename from the BootP server. The module then requests a TFTP
of the file and receives the download of the image. The module will not function
until the Flash image is downloaded from the BootP and TFTP server.
If a BootP and TFTP are not intended at this time, this process may be stopped by
resetting the module. Resetting is done by pushing the reset button on the
module, power cycling the chassis, or removing the module from the chassis and
module again looks for a BootP server, but will time-out after about four minutes.
After the time-out, the module boots from Flash memory. The next time the
power is cycled, the module will boot from Flash memory and not request the
BootP server.
Installing the Module into the SmartSwitch 9000
Chassis
To install the SmartSwitch 9000 module, follow the steps below:
The INB Terminator Modules must be installed on the rear of the fourteen slot
chassis before powering up this module. The INB Terminator Modules are not
NOTE
required on the six slot chassis. Refer to the INB Terminator Modules
Installation Guide for information and installation procedure.
1. Remove the blank panel covering the two slots in which the module is being
installed. All other slots must be covered, if other modules are not being
installed, to ensure proper airflow and cooling.
2. Attach one end of the ESD wrist strap packaged with the SmartSwitch 9000
chassis to your wrist. Plug the other end into the ESD Wrist Strap Grounding
receptacle in the lower right corner of the SmartSwitch 9000 chassis shown in

Chapter 3
Technical Overview
SmartSwitch Architecture
configurable for one of two modes of operation: traditional IEEE 802.1 switching,
or SecureFast switching. The module supports only one of these modes of
operation at any one time.
When operating in traditional IEEE 802.1 switch mode, the 9E531-24 makes
filtering/ forwarding decisions based on Destination Address (DA), with standard
IEEE 802.1D learning. 802.1Q VLANs are also supported.
Spanning tree operation for the 9E531-24 is configurable to adhere to IEEE 802.1D,
DEC, or none. The default Spanning Tree Algorithm is 802.1D.
When operating in SecureFast switch mode, all filtering/ forwarding decisions are
made on a DA-SA pair and its in and out port on a connection-orientated basis.
SecureFast switching mode provides value-added network services including
dynamic VLANs, Topology, Connectivity, IP Multicast, Control, Security,
Application, Address Management, Dynamic Mapping, and Directory services.
For example, Topology Services includes configurable options ranging from
simple spanning tree implementations to fully-meshed active topologies. Other
services and features supported in SecureFast switching mode are described in
detail in the Cabletron White Paper, IP Host Communication in Bridged, Routed
and SecureFast Networks.

Technical Overview
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 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 10 Mbps management bus located within the SmartSwitch 9000,
which 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 its
supporting logic. The diagnostic controller is designed to control the power-up
sequencing of modules, monitor the 9E531-24 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 independent of
each other if needed, they exchange information about each other’s 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 9E531-24 has been designed so that in
the event of a diagnostic controller fault, the 9E531-24 will continue to function.
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.
3-3
Technical Overview
INB Interface
Each module attaches to both INB A and INB B and has two INB ASICs. The INB
ASICs use 64-byte Ethernet frames for transmission onto the INBs at 66 MHz.
The 9X5XX modules are fully compatible with the the first generation 9X4XX
modules. The first generation modules communicate only on INB B using a
56-byte canonical frame format, at 40 MHz. If the newer module detects a first
generation module on the backplane, it automatically changes from the fast
66 MHz Ethernet frames, to the first generation compatible 40 MHz canonical
frame on INB B only. INB A is used only by the 9X5XX modules and remains at
the higher speed.
i960 Core
The i960 core provides modules host services, the SNMP protocol stacks, to
support industry standard MIBs, as well as Cabletron enterprise extension MIBs
for each media type. Management services, such as telnet, WebView and network
address to MAC address mapping, are also provided by the i960 core.
