What is the LightStream 1010 ATM Switch?
What is the LightStream 1010 ATM Switch?
The LightStream 1010 uses a five-slot, modular chassis featuring the option of dual, fault-tolerant,
load-sharing power supplies (See Figure 1.) The central slot in the LightStream 1010 is dedicated to
a single, field-replaceable ATM switch processor (ASP) module that supports both the 5-Gbps
shared memory and the fully nonblocking switch fabric. The ASP also supports the feature card and
high performance reduced instruction set (RISC) processor that provides the central intelligence for
the device. The remaining slots support up to four hot-swappable Carrier Modules (CAMs). Each
CAM supports up to two hot-swappable Port Adapter Modules (PAMs) for a maximum of eight
PAMs per switch, supporting a wide variety of desktop, backbone, and wide-area interfaces.
Figure 1 Front View of the LightStream 1010 ATM Switch
The LightStream 1010 ATM switch provides switched ATM connections to individual workstations,
servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded
twisted-pair (UTP), and coaxial cable.

•5-gigabits per second (Gbps) switching fabric
•MIPS architecture R4600 microprocessor at 100 MHz internally, 50 MHz system interface
•Memory components include:
—Main memory is used by the system software—one dynamic random access memory
(DRAM) bank of two single in-line memory modules (SIMMs), with
16 MB of DRAM as the default (upgradeable to 32 or 64 MB)
—8 MB of Flash memory for downloading the system software
•Dual PCMCIA card slot that can be used for additional Flash memory
•Air-temperature sensor for environmental monitoring
•Console serial port that can be configured for a terminal or a modem
•Auxiliary serial port for modem connection
•Ethernet port to allow Simple Network Management System (SNMP) to use an Ethernet attached
management station
In addition to these features, the ASP performs the following management functions:
•Monitors interface and environmental status
•Provides SNMP management and the console/Telnet interface
The ASP must be installed in slot 2, the middle slot when facing the front panel. (See Figure 1.)
Flash Memory The embedded Flash memory allows you to remotely load and store system software images. You
can download a new software image over the network or from a local server, and add the new image
to Flash memory or replace an existing file.
Reset Switch Access to the reset switch, located behind the faceplate of the ASP, is through a small hole
approximately 1.5 inches to the right of the ASP status LED. (See Figure 5.)

Console Port Signals
The console port on the ASP is a female, EIA/TIA-232, data communications equipment (DCE),
DB-25 receptacle. Both data set ready (DSR) and data carrier detect (DCD) are active when the
system is running. (See Figure 6.) The ready to send (RTS) signal tracks the state of the clear to send
(CTS) input. The console port does not support modem control or hardware flow control. The
console port requires a straight-through EIA/TIA-232 cable. Table 1 lists the signals used on this
port.

LightStream 1010 ATM Switch Processor Module Configuration Note 9
Preparing Network Connections
Preparing Network Connections
When preparing your site for network connections to the switch, you need to consider a number of
factors related to each type of interface:
•Type of cabling required for each type (fiber, twisted-pair, or coaxial cabling).
•Distance limitations for each signal type.
•Specific cables you need to connect each interface.
•Any additional interface equipment you need, such as transceivers, modems, channel service
units (CSUs), or data service units (DSUs). Before installing the switch, have all additional
external equipment and cables on hand. If you intend to build your own cables, refer to the cable
pinouts in the section “Installing the LightStream 1010 Switch” in the LightStream 1010 ATM
Switch User Guide publication. For ordering information, contact a customer service
representative.
Distance LimitationsThe length of your networks and the distances between connections depend on the type of signal,
the signal speed, and the transmission media (the type of cabling used to transmit the signals). For
example, fiber-optic cable has a greater channel capacity than twisted-pair cabling. The following
distance limits are provided as guidelines for planning your network connections before installation.
Serial Connections
Serial signals can travel a limited distance at any given bit rate; generally, the slower the baud rate,
the greater the distance. Table 5 shows the standard relationship between baud rate and distance for
EIA/TIA-232 signals.
Table 5 IEEE Standard EIA/TIA-232 Transmission Speed Versus Distance
Additional and Optional Connection Equipment
To install and configure the switch, you need a terminal with an EIA/TIA-232 data terminal
equipment (DTE) port and an EIA/TIA-232 data communications equipment (DCE) console cable
with DB-25 plugs at one end. You can detach the terminal (and cable) after the installation and
configuration procedures are complete.

Preparing Network Connections
Ethernet Connection Equipment
You need an Ethernet cable with RJ-45 male connectors (see Figure 8) between the Ethernet port
and the Ethernet network. See the ASP Ethernet RJ-45 connector information in the section “Enet
Port” in the chapter “LightStream 1010 ATM Switch Hardware” in the LightStream 1010 ATM
Switch User Guide.
Figure 8 Ethernet RJ-45 Interface Cable Connectors
EIA/TIA-232 Connections
EIA/TIA-232 supports unbalanced circuits at signal speeds up to 64 kbps. The ASP console
connection is a standard 25-pin D-shell connector (known as a DB-25) that is commonly used for
EIA/TIA-232 connections. Figure 9 shows the connectors at the local end of the adapter cable. The
system console port on the ASP EIA/TIA-232 connection supports only asynchronous connection.
Figure 9 EIA/TIA-232 Adapter Cable Connectors, Network End
Console Port Connection Equipment
The ASP contains an EIA/TIA-232 asynchronous console port (DB-25 receptacle).
When connecting a serial device, consider the cable as an extension of the switch for an external
connection; therefore, use null-modem cable to connect the switch to a remote DCE device such as
a modem or DSU. A straight-through cable to connect the switch to a DTE device such as a terminal
or PC.
Before you connect a terminal to the console port, configure the terminal to match the switch console
port, as follows:
•9600 baud
•8 data bits
•No parity
•1 stop bit

Safety Recommendations
Safety Recommendations
The following guidelines help ensure your safety and protect the equipment. This list is not inclusive
of all potentially hazardous situations that you may be exposed to as you install the module, so be
alert.
•Never try to lift the chassis by yourself; two people are required to lift the switch.
•Always turn off all power supplies and unplug all power cords before removing the chassis front
panel.
•Always unplug all power cords before installing or removing a chassis.
•Keep the chassis area clear and dust free during and after installation.
•Keep tools and chassis components away from walk areas.
•Do not wear loose clothing, jewelry (including rings and chains), or other items that could get
caught in the chassis. Fasten your tie or scarf and sleeves.
Warning Metal objects heat up when connected to power and ground, and can cause serious burns.
Safety with Electricity
The supervisor engine, modules, and redundant (second) power supplies are designed to be removed
and replaced while the system is operating without presenting an electrical hazard or damage to the
system. Before removing a redundant power supply, ensure that the first supply is powered on.
However, you must shut down the system before removing or replacing any of the replaceable
components inside the front panel, for example, the backplane. Never install equipment that appears
damaged.
Follow these basic guidelines when working with any electrical equipment:
•Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
•Disconnect all power and external cables before installing or removing a chassis.
•Do not work alone when potentially hazardous conditions exist.
•Never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
In addition, use the guidelines that follow when working with any equipment that is disconnected
from a power source but still connected to telephone wiring or other network cabling.
Warning Do not work on the system or connect or disconnect cables during periods of lightning
activity.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.

12 LightStream 1010 ATM Switch Processor Module Configuration Note
Safety Recommendations
•Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are
improperly handled, can result in complete or intermittent failures. The ASP and PAMs each consist
of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding,
connectors, and a handle are integral components of the carrier. Although the metal carrier helps to
protect the cards from ESD, use a preventive antistatic strap whenever you handle the ASP or PAMs.
Handle the carriers by the handles and the carrier edges only; never touch the cards or connector
pins.
Caution Always tighten the captive installation screws on the ASP and PAMs when you are
installing them. These screws prevent accidental removal of the ASP, CAMs, and PAMs, provide
proper grounding for the system, and help to ensure that the bus connectors are properly seated in
the backplane.
Following are guidelines for preventing ESD damage:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
•When removing any module, connect the equipment end of the strap to one of the captive
installation screws on an installed PAM or power supply. (See Figure 10.)

Installing and Replacing the ASP
•Handlecarriers bythe faceplatesand carrieredgesonly; avoidtouching thecard oranyconnector
pins.
•When removing a module, place the removed module component-side up on an antistatic surface
or in a static shielding bag. If the module will be returned to the factory, immediately place it in
a static shielding bag.
•Avoid contact between the modules and clothing. The wrist strap protects only the card from
ESD voltages on the body; ESD voltages on clothing can still cause damage.
Caution For safety, periodically check the resistance value of the antistatic strap. The
measurement should be between 1 and 10 megohms (Mohms).
Installing and Replacing the ASP
This section describes how to remove and install the ASP card.
Caution The ASP is a required system component. Removing an ASP while the system is
operating causes the system to shut down and may damage the processor.
Incorrect ASP Insertion and Removal
The ejector levers and installation screws (see Figure 11) align and seat the card connectors in the
backplane. Follow the installation and removal instructions carefully, and review the following
examples of incorrect insertion practices and results:
•Using the faceplate to force or slam the ASP into the slot can also damage the pins on the module
connectors if they are not aligned properly with the backplane.
•When using the faceplate (rather than the ejector levers or installation screws) to seat the ASP in
the backplane, you may need to pull the CAM or PAM back out and push it in again to align it
properly. Using the ejector levers and installation screws ensures that the card connector mates
with the backplane correctly.
•Using the faceplate to insert or remove an ASP or failing to push the ejector levers to the full
90-degree position, can leave some (not all) of the connector pins mated to the backplane, a state
which will suspend the system. Using the ejector levers and installation screws to make sure that
they are pushed fully into position ensures that all three layers of pins are mated with (or free
from) the backplane.
It is also important to use the ejector levers and installation screws when removing an ASP to ensure
that the card connector pins disconnect from the backplane in the logical sequence expected by the
system. Any ASP that is only partially connected to the backplane can hang the bus. For more
information, see the section “Installing and Replacing the ASP.”
Figure 11 shows the ejector levers, which you must use when inserting or removing the ASP or
CAMs.

14 LightStream 1010 ATM Switch Processor Module Configuration Note
Installing and Replacing the ASP
Figure 11 Ejector Levers and Captive Installation Screws (ASP Shown)
Tools Required You need a 3/16-inch flat-blade screwdriver to remove any filler (blank) PAMs and to tighten the
captive installation screws that secure the ASP in their slots. Whenever you handle ASP you should
use a wrist strap or other grounding device to prevent electrostatic discharge (ESD) damage. See the
section “Preventing Electrostatic Discharge Damage” in the chapter “Preparing for Installation” in
the LightStream 1010 ATM Switch User Guide.
Removing the ASP
ASP and CAM removal instructions are the same, except only CAMs and PAMs support
hot-swapping.
Caution The ASP is a required system component. Removing an ASP while the system is
operating causes the system to shut down and may damage the processor. Power off the system
before removing the ASP.
Take the following steps to remove an ASP (or CAM):
Step 1 Loosen the captive installation screws, by using a screwdriver, at the left and right sides of
the ASP.
Step 2 Place your thumbs on the left and right ejector levers and simultaneously push the left lever
left and the right lever right to release the ASP from the backplane connector.
Step 3 Grasp the ASP faceplate with one hand and place your other hand under the carrier to
support and guide the module out of the slot. Avoid touching the card.
Step 4 Carefully pull the ASP straight out of the slot, keeping your other hand under the carrier to
guide it. Keep the module at a 90-degree orientation to the backplane.
Step 5 Place the removed ASP on an antistatic mat or antistatic foam.

Step 4 Keep the ASP at a 90-degree orientation to the backplane and carefully slide it into the slot
until the faceplate makes contact with the ejector levers.
Step 5 Use your thumb and forefinger of each hand and simultaneously push the left lever and the
right lever in to fully seat the ASP in the backplane connector.
Note Always use the ejector levers when installing or removing the ASP. A module that is partially
seated in the backplane causes the system to halt and subsequently crash.
Step 6 Use a screwdriver to tighten the captive installation screws on the left and right ends of the
ASP.
Step 7 Attach network interface cables or other devices to the interface ports.
Step 8 If needed, turn the power back on. See the section “Starting the System” in the chapter
“Installing the LightStream 1010 ATM Switch” in the LightStream 1010 ATM Switch User
Guide.
Step 9 Check the status of the interfaces as follows:
•If this installation is a replacement PAM, use the show configuration or show atm
interface[card/subcard/port] command to verify that the system has acknowledged the
new interfaces and brought them up.
•See the publications LightStream 1010 ATM Switch Software Configuration Guide and
LightStream 1010 ATM Switch Command Reference for all software instructions and
information.
Configuring the Interfaces
After you install the module, use the following information to configure the module and the
individual interfaces on the ASP module. In the LightStream 1010 ATM Switch User Guide the
section “LightStream 1010 ATM Switch Hardware” contains an overview of the port and module
numbering scheme used to configure the ASP. The section “Configuring the LightStream 1010 ATM

Configuring the Interfaces
Switch” describes how to configure the ports on the FDDI or CDDI module. The section
“Confirming the Installation” describes the procedures you should use to confirm that the ASP is
configured correctly.
Port AddressesEach interface (or port) in the switch is designated by several different types of addresses. The
physical interface address is the actual physical location (card/sub/port) of the interface connector
within the chassis. The system software uses the physical addresses to control activity within the
switch and to display status information. These physical card/subcard/port addresses are not used by
other devices in the network; they are specific to the individual switch and its internal components
and software.
The following sections describe how the LightStream 1010 switch assigns and controls both the
physical(card/subcard/port) andMedia AccessControl (MAC)-layeraddresses forinterfaceswithin
the chassis.
Port IDs In the LightStream 1010 switch, port IDs specify the actual physical location of each PAM port on
the front of the switch. (See Figure 14.) The address is composed of a three-part number in the
format card/subcard/port number. The first number identifies the slot in which the module is
installed. Module slots are numbered 0 to 4 from top to bottom. The second number identifies the
subcard or PAM number. The PAMs are numbered 0 and 1 with 0 being the left PAM facing the front
of the switch. The third number identifies the physical port number on the module. The port numbers
always begin at 0 and are numbered from the left port to the right port, facing the front of the switch.
The number of additional ports (/1, /2, and so on) depends on the number of ports available on the
module.
Interface ports maintain the same port ID regardless of whether other modules are installed or
removed. However, when you move a module to a different slot, the first number in the address
changes to reflect the new slot number. For example, on a 4-port 155 UTP PAM in chassis slot 1 in
PAM slot 0, the address of the left port is 1/0/0 and the address of the right port is 1/0/3. If you
remove the 4-port 155 UTP PAM from slot 1 and install it in slot 4, the addresses of those same ports

Configuring the Interfaces
You can identify module ports by physically checking the card/subcard/port location on the front of
the switch. You can also use software commands to display information about a specific interface,
or all interfaces, in the switch. To display information about every interface, use the show interface
command without parameters. To display information about a specific interface, use the show
interface command with the interface type and port address in the format show interface atm
card/subcard/port. This command is described in the LightStream 1010 ATM Switch Command
Reference publication.
