SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
The IOM-29-4-MIX, IOM-29-4-IR, IOM-29-4-LR, IOM-39-1 and IOM-39-1-LR connectors use Class 1 Laser
transceivers. The 6A-IOM-29-4, 6A-IOM-29-4-IR, 6A-IOM-29-4-LR, 6A-IOM-39-1 and 6A-IOM-39-1-LR
connectors use Class 1 Laser transceivers.Read the following safety information before installing or operating one of
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.
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 normal conditions) is -12.6dBm or 55x10-6 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 0.8 W cm-2 or 8x103W m-2 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, you must remove power from the network adapter.

FIBER OPTIC PROTECTIVE CAPS
Warning READ BEFORE REMOVING FIBER OPTIC PROTECTIVE CAPS.
Cable assemblies and MMF/SMF ports are shipped with protective caps to prevent contamination. To avoid
contamination, replace port caps on all fiber optic devices when not in use.
Cable assemblies and MMF/SMF ports that become contaminated may experience signal loss or difficulty inserting
and removing cable assemblies from MMF/SMF ports.
Contamination can be removed from cable assemblies by:
1. Blowing surfaces with canned duster (Chemtronics p/n ES1270 or equivalent).
2. Using a fiber port cleaning swab (Alcoa Fujikura LTS p/n ACT-01 or equivalent) saturated with
optical-grade isopropyl alcohol, gently wipe the end surface of ferrules first; then wipe down the
sides of both ferrules.
3. Blow ferrule surfaces dry with canned duster.
Contamination can be removed from MMF/SMF ports by:
1. Using the extension tube supplied with canned duster, blow into the optical port, being careful not
to allow the extension tube to touch the bottom of the optical port.
2. Reconnect cable and check for proper mating.If problems remain, gently wipe out optical port with
a DRY fiber port cleaning swab and repeat step 1.
Warning To avoid contamination, replace port caps on all fiber optic devices when not
in use.

1 INTRODUCTION
Welcome to the SmartSwitch 9A100 Installation and Setup Manual. The SmartSwitch 9A100 ATM switch is a module
that fits into the SmartSwitch 9000 chassis. You can install up to seven SmartSwitch 9A100 switches into a 14-slot
SmartSwitch 9000 chassis; or upto three switches into a 6-slot chassis. The module is hot swap-able, meaning that you
can install and remove it without turning off or disconnecting the chassis. This manual will help you quickly and easily
install and configure your SmartSwitch 9A100 switch.
This manual provides instructions for installing and setting up the SmartSwitch 6A000 ATM switch module.
This manual provides information about
•Unpacking and inspecting your switch module
•Installing your switch module in the SmartSwitch 9000 chassis
•Configuring your switch to be functional on your network
•Using the command line console
•Using the SmartSwitch ATM Administrator graphical network management software
•Obtaining customer support
This manual also provides detailed mechanical, electrical, and performance specifications for the SmartSwitch 9A100
ATM switch module.
Note For additional information about using the SmartSwitch 9A100, see the
SmartSwitch ATM User Guide. For a complete explanation of all SmartSwitch
9A100 console commands, see the SmartSwitch ATM Switch Reference Manual.

2 SWITCH INSTALLATION
This chapter explains how to inspect and install your SmartSwitch 9A100 ATM switch module.
2.1 UNPACKING THE SWITCH
Remove the accessory carton from the SmartSwitch 9A100 shipping box. Carefully remove the switch from its
packing material.
2.1.1 Accessory Carton Contents
Open the accessory carton and check that it contains the following items:
— 7-foot UTP cable, terminated on both ends with RJ-45 connectors
— RJ-45 to 9-pin female adapter (labeled PC)
— Console cabling instruction sheet
— CDROM containing the following:
-SmartSwitch 9A100 operating firmware
-SmartSwitch ATM switch documentation in Adobe Acrobat format
-SmartSwitch ATM Administrator software
-MIB files
-SmartSwitch 9A100 Release Notes
Note If any of these items are missing, contact Cabletron Global Support Center
immediately.

2.2 INSPECTING THE SWITCH
Depending on the configuration ordered, your switch looks similar to the unit in Figure 2-1. The SmartSwitch
9A100-04 has four I/O modules.
Figure 2-1 SmartSwitch 9A100-04 front panel
Inspect the switch and make certain that its configuration corresponds to what was ordered. Also, make certain that the
input/output (I/O) modules are of the correct type and number (See Table 2-1).

Installing the Switch Switch Installation
2.3 INSTALLING THE SWITCH
The SmartSwitch 9A100 is hot swappable, meaning that you can install and remove it without turning off or
unplugging the SmartSwitch 9000 chassis. The following list shows how many switch modules can be installed in each
chassis:
•You can install up to three switch modules in a 6-slot chassis. In this configuration, the SmartSwitch
9A100 modules provide up to 45 user ports.
•You can install up to seven switch modules in a 14-slot chassis. In this configuration, the
SmartSwitch 9A100 modules provide up to 105 user ports.
Connect modules with inter-module trunks if traffic must cross between modules.
Note When redundant power supplies are installed in the chassis, the switch module
recognizes only one of them. However, the redundant power supply feature
performs correctly; if one power supply fails, the other one takes over.
Follow the instructions below to install the switch module into the chassis. Refer to Figure 2-2. You do not need to turn
off or unplug the chassis before inserting or removing the switch module. However, if you insert the switch module
with the power on, there is a 6-second delay before it begins to operate.
1. Remove the metal blanks from two adjacent empty slots in the chassis.
2. Open the ejectors at the top and bottom of the switch module.
3. With the LEDs at the top, align the top and bottom of the SmartSwitch 9A100 with the tracks in the
slot.
4. Slide the switch into the chassis. The switch module obscures the view of the tracks at the bottom of
the chassis, so be sure to look at that area as you begin to slide the switch into the chassis.
5. Close the ejectors. The installation is complete.
