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.

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-optic, coaxial, or twisted-pair 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 representativ

Distance Limitations

The 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.

1. LOF = loss of frame

2. LCD = loss of cell delineation

3. AIS = alarm indication signal

Safety Recommendations

The following guidelines will help to 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.

Safety Recommendations

• 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.

LightStream 1010 ATM Switch 622 SM/MM Port Adapter Module Configuration Note 9

Page 10

Safety Recommendations

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.

• 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. Each PAM consists 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 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 P AMs when you are installing them.

These screws prevent accidental removal of the P AMs, 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 9.)

• Handle carriers by the faceplates and carrier edges only; avoid touching the card or any connector

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 PAMs

All PAMs support hot-swapping, which allows you to install, remove, replace, and rearrange the PAMs without turning off the system power. When the system detects that a P AM has been installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the PAM, and resumes system operation without any operator intervention.

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.

What is Hot-Swapping?

The hot-swap feature allows you to remove and replace modules while the system is operating; you do not need to notify the software or shut down the system power. All CAMs and PAMs (except for the ASP) support hot-swapping.

LightStream 1010 ATM Switch 622 SM/MM Port Adapter Module Configuration Note 11

Page 12

Installing and Replacing PAMs

Each CAM contains a bus-type connector that mates with the system backplane. Each card connector consists of a set of tiered pins, in three lengths. The pins send speciﬁc signals to the system as they make contact with the backplane. The system assesses the signals it receives and the order in which it receives them to determine what event is occurring and what task it needs to perform, such as reinitializing new interfaces or shutting down removed ones.

For example, when inserting a CAM, the longest pins make contact with the backplane ﬁrst, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them. The system expects to receive signals from the individual pins in this logical sequence, and the ejector levers help to ensure that the pins mate in this sequence.

When you remove or insert a P AM, the backplane pins send signals to notify the system, which then performs as follows:

1 Rapidly scans the backplane for conﬁguration changes. 2 Initializes all newly inserted PAMs, noting any removed interfaces and placing them in the

administratively shutdown state.

3 Brings all previously conﬁgured interfaces on the P AM back to the state they were in when they

were removed. If a PAM, similar to the one that was removed, has been reinserted into a slot, then its ports are conﬁgured and brought online up to the port count of the original PAM.

Unconﬁgured PAMs installed for the ﬁrst time start up in the shutdown state. The system identiﬁes them as present but unconﬁgured. Each must be manually conﬁgured from the command line.

Tools Required

Hot-swap functionality enables you to add, remove, or replace P AMs with the system online, which provides a seamless method to users on the network, maintains all routing information, and ensures session preservation.

When you insert a new PAM, the system runs a diagnostic test on the new interfaces and compares them to the existing conﬁguration. If this initial diagnostic fails, the system remains ofﬂine for another 15 seconds while it performs a second set of diagnostic tests to determine whether or not the PAM is faulty and if normal system operation is possible.

If the second diagnostic test passes, which indicates that the system is operating normally and the new PAM is faulty, the system resumes normal operation but leaves the new interfaces disabled.

If the second diagnostic test fails, the system crashes, which usually indicates that the new P AM has created a problem in the bus and should be removed.

Caution To avoid erroneous failure messages, allow at least 15 seconds for the system to

reinitialize and note the current conﬁguration of all interfaces before you remove or insert another PAM.

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 CAMs and PAMs in their slots. Whenever you handle CAMs and PAMs, 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.

Following are detailed steps for removing PAMs and successfully performing hot-swap.

Caution Handle PAMs by the carrier edges only to prevent ESD damage.

Step 1 Choose a PAM slot (shown in Figure 11) in a CAM and make sure there is enough

clearance to accommodate any interface equipment you connect directly to the P AM ports. If possible, place PAMs between empty slots that contain only PAM ﬁller plates.

Figure 11 PAM Slot Numbers

Step 2 PAMs are secured with one captive installation screw in the center of the faceplate. Use a

1/4-inch ﬂat-blade screwdriver to loosen the captive installation screw and remove the PAM ﬁller (or the existing PAM) from the PAM slot you want to use.

Page 14

Installing and Replacing PAMs

Note Always use the captive screw to install or remove P AMs. A module that is partially seated in

the CAM connector causes the system to halt and subsequently crash.

Step 7 Attach network interface cables or other devices to the interface ports. Step 8 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 publication LightStream 1010 ATM Switch Software Conﬁguration Guide and

LightStream 1010 ATM Switch Command Reference for all software instructions and information.

Caution All PAMs support hot-swapping. The ASP is a required system component. Removing an

ASP while the system is operating will cause the system to shut down.

Port Adapter Module Conﬁgurations

The P AMs support different media and interface types. The conﬁguration commands used with these different PAMs vary according to P AM type. For complete PAM conﬁguration information, refer to the publications LightStream 1010 ATM Switch Conﬁguration Guide and LightStream 1010 ATM

Switch Command Reference.

Configuring the Interfaces

Conﬁguring the Interfaces

After you install the module, use the following information to conﬁgure the module and the individual interfaces on the 622 MM/SM modules. In the LightStream 1010 A TM Switch User Guide the section “LightStream 1010 A TM Switch Hardware” contains an overview of the port and module numbering scheme used to conﬁgure the 622 P AMs. The section “Conﬁguring the LightStream 1010 ATM 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 622 P AMs are conﬁgured correctly.

Port Addresses

Each interface (or port) in the switch is designated by several different types of addresses. The physical interface address is the actual physical location (card/subcard/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) and Media Access Control (MAC)-layer addresses for interfaces within the chassis.

Port IDs

In the LightStream 1010 switch, the port ID specify the actual physical location of each PAM port on the front of the switch. (See Figure 13.) The address is composed of a three-part number in the format card/subcard/port. 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 P AM from slot 1 and install it in slot 4, the addresses of those same ports become 4/0/0 and 4/0/3.

Figure 13 ATM Interface Port ID Address Examples

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. T o 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.

622 SM/MM Conﬁguration Defaults

When the switch is powered on initially without any previous conﬁguration data, the A TM interfaces are conﬁgured automatically on the physical ports. ILMI and the physical card type are used to automatically derive the ATM interface type, UNI version, maximum VPI and VCI bits, ATM interface side, and ATM UNI type.

If ILMI has been disabled or if the connecting end node does not support ILMI, the following defaults are assigned to all interfaces:

• ATM interface type = UNI

• UNI version = 3.0

• Maximum VPI bits = 8

• Maximum VCI bits = 14

• ATM interface side = network

• ATM UNI type = private

The following defaults apply to the OC12 PAM:

622 SM/MM Configuration Defaults

• Framing = sts-12c

• Clock-source = free-running

• STS-stream scrambling = on

• Cell payload scrambling = on

You can accept the default ATM interface conﬁguration or overwrite the default interface conﬁguration using the command line interface commands. These commands are described in the section “Conﬁguring Virtual Connections” in the LightStream 1010 ATM Switch Software Conﬁguration Guide.

To test the conﬁguration refer to the section “Conﬁrming the Installation” in the LightStream 1010 ATM Switch User Guide.
