Hardware Installation

This chapter provides procedures for installing a LightStream 2020 multiservice ATM switch (LS2020 switch) in a networking environment. Installing an LS2020 switch in volv es sev eral tasks in two major categories:

1 Installing the LS2020 switch hardware

Separate sections in this chapter are devoted to the following topics:

— “Unpacking and Inspecting the LS2020 Switch Hardware” — “Installing an LS2020 Switch in Rack” — “Wiring a DC-Powered System” — “Installing Fantails” — “Attaching Data Cables” — “Closing the Chassis” — “Applying System Power”

2 Performing basic conﬁguration procedures

The basic conﬁguration tasks for the LS2020 switch are accomplished through conﬁguration scripts provided in this chapter.

Note Refer to the LightStream 2020 Release Notes for important, release-speciﬁc information that

may not appear elsewhere in the LS2020 documentation set.

Unpacking and Inspecting the LS2020 Switch Hardware

When unpacking the LightStream 2020 switch, you should inspect the shipping container contents to ensure the shipment is complete as well as check for damage that may have occurred during shipment.

Step 1 Check the shipping container before removing the LS2020 switch hardware from the

loading dock and inspect it for any signs of in-transit damage.

Step 2 Transport the container to the systems area where the LS2020 switch is to be installed. Step 3 Cut the packing straps and lift the cardboard box off the LS2020 chassis. Remove the

packing material and bill of materials.

Step 4 Check the bill of materials against the shipment received.

Hardware Installation 2-1

Installing an LS2020 Switch in Rack

Step 5 Inspect all external surfaces of the chassis for signs of damage. Pay special attention to

areas of the chassis corresponding to visible damage to the shipping container.

Step 6 Document any damage noted during the inspection. Step 7 Contact your LS2020 vendor if your LS2020 switch has been damaged during shipment.

Installing an LS2020 Switch in Rack

This section explains how to mount an LS2020 chassis in an equipment rack.

Note For physical stability, when an LS2020 chassis is installed in a rack, the equipment

conﬁguration should comply with UL Standard 1950, Par. 4.1.1, and IEC 950, 4.1.1.

Cooling Air and Hardware Placement

An LS2020 chassis takes in cooling air at the bottom of the front panel and exhausts it at the top rear and right side of the chassis. (The air vents on the right side of the chassis can safely be covered by the rack side panels, but they should not otherwise be blocked.) To minimize the potential for thermal problems, position the LS2020 chassis so that

• The air intake panel is not located near the exhaust of other equipment.

• The exhaust is not located near the air intake of other equipment.

Required Tools

Ensure that you have the following items on hand before you begin installing the LS2020 switch:

• A number 2 Phillips screwdriver for mounting the chassis.

• A 5/16-inch slotted-tip screwdriver for removing blowers, power supplies, and boards from the

chassis.

• An ESD wrist strap for grounding yourself to the chassis.

• Antistatic shielding bags or antistatic mats for protecting components removed from the chassis.

• Appropriate material-handling equipment for lifting the LS2020 switch into the rack.

• For AC-powered systems: an LS2020 Country Power Kit, which includes a power cord and

mounting hardware for the chassis.

• For DC-powered systems: a DC Mounting Kit, which contains mounting hardware for the

chassis, plus equipment needed by the electrician for wiring the system (see the subsection entitled “Preparation for Wiring” later in this chapter).

Rack Installation Procedure

To mount the LS2020 switch in an equipment rack, perform the following steps:

Step 1 Ensure that the power cord to the system is disconnected before you begin with the

installation.

Step 2 Put on the ESD wrist strap and connect it to a grounding jack on the front or the rear panel

of the LS2020 chassis.

2-2 LightStream 2020 Installation Guide

Installing an LS2020 Switch in Rack

Step 3 Remove the following chassis components to reduce the weight of the system during

installation.

• Blowers (top front and top rear)

• Power supplies (right rear)

These components are located behind removable covers. Figure 2-1 shows the front view of the LS2020 chassis, while Figure 2-2 shows the rear view of the chassis.

If your system is fully conﬁgured with function cards, you may also remove some or all of these cards to further reduce the weight of the chassis. (Refer to the LightStream 2020 Hardwar e Refer ence and T r oubleshooting Guidefor component removal instructions.) Put all removed electronic components in antistatic shielding bags or place them on antistatic mats.

Note Do not remove disk assemblies as a means of reducing chassis weight.

Step 4 Determine the desired mounting position in the rack for the LS2020 switch. Attach the clip

nuts from the country kit or the rack mounting kit to the appropriate positions on the rack rails.

See Figure 2-1 for the location of mounting screw slots. (If your rack has metric-threaded or non-standard rails, you may need to provide your own mounting hardware.)

Step 5 Lift the LS2020 chassis into the desired mounting position in the rack.

Warning An LS2020 chassis is heavy, particularly if it is completely conﬁgured with function

cards. (The weight of the system ranges from 94 to 147 pounds, depending on the system conﬁguration.) Do not risk personal injury or equipment damage by attempting to transport or lift the system without assistance.

Caution Do not use the disk assembly handles to lift the chassis. These handles, shown in

Figure 2-1, are not designed for weight-bearing loads and may break off if used to lift the chassis.

Step 6 Using the mounting screws and washers included in your country kit or rack mounting kit,

secure the ﬂanges on the front of the LS2020 chassis to the rack.

Step 7 Replace any items that you removed from the chassis in Step 3 above (blowers, power

supplies, function cards, and covers) before installing the chassis into the rack.

Wiring a DC-Powered System

The procedure in this section explains how to wire a DC-powered LS2020 switch to a DC power source. This task should be performed only by qualiﬁed service personnel or a licensed electrician.

This section applies only to systems with the DC power option. If you have a standard AC-powered system, skip to the section “Installing Fantails.”

For general information on DC-powered LS2020 systems, see the LightStream 2020 Hardware

Reference and Troubleshooting Guide. For power speciﬁcations, see the LightStream 2020 Site Planning and Cabling Guide.

Preparation for Wiring

Note the following in preparation for wiring a DC-powered LS2020 switch:

• The system power connection on the DC po wer tray is provided by a 3-position terminal block,

as shown in Figure 2-3. The –48, –48RTN, and CHS GND connections providing –48VDC power to the system require a minimum of number 10AWG wire for the 24A-rated load. The terminal block is rated to accept up to number 8A WG solid wire. The use of ferrules to terminate these wires is recommended.

• The alarm circuit connection to the DC power tray is provided by a smaller 3-position terminal

block, also shown in Figure 2-3. The COM, NO, and NC connections providing the circuit breaker alarm indication should be wired with number 22A WG or larger wire. The use of number 6 spade or ring lug terminals for these connections is recommended.

• Obtain a slot-tip screwdri v er for securing the system po wer terminals and a Phillips scre wdri v er

for securing the alarm circuit terminals.

To wire a DC-powered LS2020 switch to a DC power source, perform the following steps:

Step 1 Ensure that the circuit breaker/power switch on each DC power tray is OFF. Step 2 Ensure that power to the circuit to which you will connect the LS2020 switch is OFF. Step 3 Connect the three system power wires to the LS2020 terminal block, using the slot-tipped

screwdriver to secure the terminals. Do not remove the terminal covers at the base of the terminal block.

Step 4 To connect the alarm circuit, remove the plastic terminal block co ver (see Figure 2-3) and

set it aside for the time being.

Step 5 Connect the alarm wires to the LS2020 terminal block, using the Phillips screwdriver to

secure the terminals.

Step 6 Replace the terminal block cover.

Hardware Installation 2-7

Installing Fantails

Step 7 Repeat the procedure above if the LS2020 switch contains a second DC power tray. Step 8 Observe the green power LED on the front of the power tray when power is applied. If the

LED is not lit, check for incorrectly connected wires or problems in the DC power source.

Installing Fantails

This section explains how to mount and connect fantails in your LS2020 switch (see Figure 2-4). Fantails provide connectors for data cables on low-speed (V.35, X.21 and EIA/TIA-449) lines and T3 lines that are attached to cell line card/T3 access cards in an LS2020 switch.

If your system has no low-speed or cell line card/T3 modules, skip to the section “Attaching Data Cables.”

Required Tools and Equipment

Obtain the following equipment and tools in preparation for installing fantails:

• Fantails in the desired quantity (provided by Cisco Systems).

• Required fantail cables (provided by Cisco Systems).

• Fantail mounting screws, clip nuts, and w ashers (provided by Cisco Systems). If your equipment

rack has metric-threaded rails, you must provide appropriate mounting screws.

• A 5/16-inch slotted-tip screwdriver.

• Adhesive labels for making appropriate notations on each fantail.

• A grounding wrist strap for ESD protection during fantail installation.

Note If you are installing X.21 fantails and you plan to conﬁgure the ports as DTEs, you must

obtain and install a 15-pin male-to-male gender converter on each port in order to change the female connector to a male connector. Note, however, that the gender converters are not required for X.21 ports conﬁgured as DCEs.

Fantail Installation Procedure

To install fantails in your LS2020 switch, perform the following steps:

Note Before installing fantails, check the interface jumpers on each low-speed access card. These

jumpers must be set to the interface displayed on the fantail(s) for that card. For instructions on setting interface jumpers, see the LightStream 2020 Hardware Refer ence & Troubleshooting Guide.

Step 1 Select a position on the rack to mount the fantail. Attach the four clip nuts provided with

the fantail to the appropriate holes in the rails.

Step 2 Put on the ESD wrist strap and connect it to the ESD jack on the rear of the LS2020 chassis.

Hardware Installation 2-9

Connecting Cables

Step 3 Attach the fantail cable(s) to the back of the fantail and the corresponding access card in

the chassis. (Performing this task now is recommended, rather than installing the fantail ﬁrst and having to reach behind it to attach the cable(s) to a connector that you cannot observe directly.) Note that the cable is reversible; that is, either end of the cable can be connected to the fantail. Exercise care to av oid suspending the weight of the fantail on the cable.

Step 4 Attach the fantail to the rails with the mounting screws and washers provided, using a

slot-tip screwdriver.

Step 5 Label the fantail with the slot number or the name of the interface module to which the

fantail is connected.

Step 6 Repeat Step 1 and Steps 3 through 5 to install additional fantails in your LS2020 switch.

Note If you are mounting an X.21 fantail, set the DTE/DCE switches for each port to the desired

mode. (See theLightStream 2020 Hardwar e Reference and T r oubleshooting Guidefor more detailed instructions on conﬁguring X.21 ports as DTEs or DCEs.) If you select a DCE interface, note that you must install a gender converter on each DTE port in order to change the female connector to a male connector.

Connecting Cables

To connect cables to your LS2020 switch, perform the following steps:

Step 1 If you have any FDDI cards in your LS2020 switch, install connector keys provided by the

cable vendor onto your FDDI cables. The keys make it impossible to attach a cable to the wrong kind of connector on the FDDI card.

Step 2 If you have any OC-3c or FDDI cards in your LS2020 switch, remove and save the

protective covers on the ports that will be used. Leave any unused ports covered.

Step 3 If you have any E1 CEMAC cards (circuit emulation access cards) in your LS2020 switch,

check the user-settable jumper settings on the card(s). These jumpers allow you to select termination impedance and grounding on the receive line, as well as the pulse amplitude and grounding on the transmit line.

As default values, the termination impedance and pulse amplitude jumpers are set to 120 ohms, and the transmit and receive lines are not grounded. Use these default settings if you plan to use the E1 CEMAC card without a fantail. Ho wever, if you do plan to use a fantail (which provides 75-ohm interfaces), you must use 75-ohm settings for termination impedance and pulse amplitude and set grounding to on.

For more detailed information about changing the E1 CEMAC card jumper settings, consult the LightStream 2020 Hardware Reference and Troubleshooting Guide.

Step 4 Connect any available external data cables. (Refer to the LightStream 2020 Site Planning

and Cabling Guide for details about data cables and connectors.) If you have Ethernet cards

in your LS2020 switch, note that each card supports only eight ports (0 through 7), although 10 physical connectors are available on the access card. Note also that you can use only one of the 10Base-T or AUI connections on ports 0 and 7.

2-10 LightStream 2020 Installation Guide

Note For ease of maintenance, route cables at the back of the LS2020 chassis in a way that enables

you to later remove any access card without disconnecting cables attached to other access cards or fantails.

Closing the Chassis

Before applying system power, check the front and back of the system to ensure that all boards, disks, blowers, bulkheads, ﬁller panels, and covers are in place and secured ﬁrmly to the chassis frame. When in place, these items form an enclosure that serves three important functions:

• Prevents exposure to hazardous voltages and currents inside the chassis.

• Conﬁnes electromagnetic interference (EMI) within the chassis, a requirement for meeting EMI

standards. Emissions from an LS2020 switch that is not fully enclosed may interfere with other ambient equipment.

• Maintains the ﬂow of cooling air through the chassis. Air ﬂo w disturbances can result in thermal

problems that may induce electronic component failures.

Caution Do not operate an LS2020 switch without ﬁrst ensuring that all components removed from

the installation procedure are restored to their original position in the chassis. The LS2020 switch must operate properly at all times to avoid exposure to hazardous v oltages, to conﬁne EMI radiation within the enclosure, and to maintain the proper ﬂow of cooling air through the chassis.

Closing the Chassis

Applying System Power

Y ou can po wer your LS2020 switch with either an AC or a DC po wer tray . In addition, you can equip your LS2020 switch with an optional (redundant) power tray of like type (see Figure 2-5).

To power up an LS2020 switch, perform the following steps:

Step 1 If you have an AC-powered system, plug one end of the po wer cord into the po wer inlet on

the power tray and plug the other end into a dedicated AC po wer outlet. Note that the power inlet on the rear panel has a wire bail latch for securing the power cord to the chassis. Flip the AC power switch to the left of the power inlet to the up position.

If your system is equipped with a second AC power tray, repeat Step 1 for this tray.

Step 2 If you have a DC-powered system, ﬂip the DC power switch located on the power tray panel

to the up position. (This step assumes that your LS2020 switch has already been connected to a DC power source by qualiﬁed service personnel or a licensed electrician, as described in the section “Wiring a DC-Powered System”).

If your system is equipped with a second DC power tray, repeat Step 2 for this tray.

Note When the LS2020 switch is powered up, the blowers start running and the test and control

system (TCS) applies power to the cards and initiates the power -on self test (POST) sequence. LEDs on the power tray(s) and the individual cards indicate operational status, as reﬂected in the ﬂow chart in Figure 2-6. The power-up sequence, including the POST, takes a minute or less.

Step 3 If the green ready (RDY) LED on each card lights up (indicating operational status),

proceed to the next section “Installing Modems.” If a yellow fault (FLT) LED stays lit on any card, indicating the existence of a problem, do either of the following:

Installing Modems

You should install a modem for each switch card in the LS2020 chassis. In the event that an operational problem causes a node to be isolated from the rest of the network, the modem may be the only means available for communicating with that node.

The modem connects to the modem port on the modem/console assembly bulkhead at the back of the LS2020 chassis, using the modem cable described in the LightStream 2020 Site Planning and Cabling Guide.

Hardware Installation 2-13

Basic LS2020 Configuration Tasks

A modem attached to an LS2020 node must be a V.42 Hayes-compatible unit capable of operating at 2400 baud. The following modems are compatible with the LS2020 switch:

• Zoom 9624V

• Zoom FXV (FXV9624V)

• Hayes SmartModem 2400 V.24

For information on the default modem port settings and how to change them, see the LightStream 2020 Network Operations Guide.

Basic LS2020 Conﬁguration Tasks

This section explains how to enter basic conﬁguration information for your LS2020 chassis in order to make it operable in your networking environment and manageable from your NMS. You must perform these procedures for the NP card(s) in your LS2020 chassis.

Note If you experience a problem while performing basic conﬁguration tasks, you may need to shut

down and restart the system. Refer to theLightStream 2020 Hardwar e Refer ence & T r oubleshooting Guide for instructions on performing an orderly shutdown.

Required Conﬁguration Information

You need to have the following information available before beginning the basic conﬁguration procedures:

• Passwords for the four default login accounts for the LS2020 switch root, oper, npadmin, and

ﬂdsup.

• Host name for the LS2020 node.

• IP address and subnet mask for the:

— Primary NP, as well as for the backup NP, if present. — NP Ethernet interface, if present. — Default router for the LS2020 network. This IP address should be conﬁgured only if the

default router and the NP Ethernet interface are attached to the same LAN.

• Trunk port conﬁguration information for one or more trunk ports on the node. For nodes not

directly connected to the NMS, the trunk port will be used to load a full LS2020 node conﬁguration from the NMS.

Passwords

You must create a password for each of the four default login accounts on the LS2020 switch: root, oper, npadmin, and ﬂdsup. See the LightStream 2020 Network Operations Guide for more

information about default login accounts. A password must be at least six characters in length. It can be as long as you wish, but only the ﬁrst

eight characters are used. Any combination of characters is acceptable, including spaces.

2-14 LightStream 2020 Installation Guide

Host Name

Y ou must assign a unique host name to each LS2020 node. Typically , a name can be chosen to reﬂect the node’s geographic location (for example, Tokyo2) or its function within an organization (for example, mfg3).

The name may consist of any combination of letters and numbers up to 32 characters, but it must not begin with a number. Thus, Pensacola23 is a valid host name, but 23Pensacola is not; similarly, Pensacola.23 is not a valid name, since it contains a character other than a letter or number.

IP Addresses and Masks

For each LS2020 node, you must provide from one to four IP addresses and associated network masks, as described below:

• Primary NP address and mask (for every LS2020 node in the network)

Nodes in an LS2020 network use their primary NP addresses to communicate network management trafﬁc to each other.

Note All NP addresses within the same LS2020 network must have the same network number , and

each node must have a unique host ID.

Basic LS2020 Configuration Tasks

• Subnet mask for the primary NP address

The subnet mask speciﬁes which portion of the IP address is the network number and which portion is the host ID. This mask should be conﬁgured to be the same for all nodes in a given LS2020 network.

• Secondary NP address, only if a backup NP is present in the chassis

If a node has a second (backup) NP , the node uses its primary and secondary NP addresses to pass network management trafﬁc between the two NPs within the node. The primary NP address is used by whichever NP is active.

Note All NP addresses within the same LS2020 network must have the same network number , and

each node in the network must have a unique host ID.

• Ethernet address and mask of the NP (when either the primary or secondary NP is connected to

an Ethernet LAN) An Ethernet LAN may be attached to the NP for communicating network management trafﬁc

between the node and the NMS. If an Ethernet LAN is connected to the NP, the NP’s Ethernet IP address must be conﬁgured. If a backup NP is present in the chassis, both NPs must be attached to the same Ethernet segment. The NP’ s Ethernet IP address is used by whichev er NP is primary (active).

Note This Ethernet IP address has the network number of the attached Ethernet LAN (which must

be different from the network number of the LS2020 network). The Ethernet IP address also has a host number that is assigned by the Ethernet LAN administrator.

Hardware Installation 2-15

Basic LS2020 Configuration Tasks

• Subnet mask for the NP’s Ethernet address

The subnet mask for the NP’s Ethernet address speciﬁes which portion of the IP address is the network number and which portion is the host ID. This mask is the same for all nodes on the Ethernet LAN attached to the primary NP. You can obtain the subnet mask from the Ethernet LAN administrator.

• Default router (only if needed for reaching the NMS)

If an Ethernet LAN is attached to the primary NP, but the NMS is not directly connected to that Ethernet LAN, a default router can be conﬁgured as the means for communicating network management trafﬁc between the NP and the NMS. The IP address for the default router has the same network number as the attached Ethernet LAN (this number must be different from the network number of the LS2020 network). The IP address for the default router also has a host number assigned by the Ethernet LAN administrator.

If you plan to operate with a single physical LS2020 network under your network number and the LS2020 network is a class C network, record 255.255.255.0 as the subnet mask. (For a class B network without subnetting, record 255.255.0.0 as the subnet mask; for a class A network without subnetting, record 255.0.0.0 as the subnet mask.)

Network management can also be accomplished by means of an Ethernet LAN connected to an ordinary Ethernet data port (that is, an Ethernet access card port) on the LS2020 node. The NMS, however, must be attached directly to that Ethernet LAN. In this case, do not conﬁgure the NP’s Ethernet address or default router address. Furthermore, in the current release, to provide access control over Ethernet ports that can be used by an NMS, a port conﬁguration parameter has been added which allows you to specify whether IP trafﬁc destined for an NP is forwarded or blocked. This conﬁguration parameter, lsLanPortNPTrafﬁcFilter, determines whether or not inbound frames received on an Ethernet port are delivered to any NP in the network. The default value of this parameter for all access card Ethernet LAN ports is to block IP trafﬁc to an NP. Therefore, you must explicitly set this parameter, on a port-by-port basis, to forward trafﬁc to an NP . The Ethernet ports on the NP access cards remain unaffected in the current release, that is, these ports always pass IP trafﬁc to the NP.

For detailed information about conﬁguring Ethernet port attributes, see the LightStream 2020 Conﬁguration Guide. For detailed information about IP addresses, subnet masks, and network classes, see the LightStream 2020 Site Planning and Cabling Guide.

Trunk Port Information

For each trunk port that you conﬁgure, the following information is required:

• The trunk card type: low speed (T1/E1 rate), T3, E3, or OC-3c

• The number of the chassis slot in which the trunk card is located

• The port number (except on an OC-3c card, which has only one trunk port)

• Additional port information needed varies, depending on the type of port being conﬁgured, as

indicated below:

— For a low-speed trunk port, specify the DTE/DCE type and DTE or the DCE bit rates. — For a T3 trunk port, specify the line type (C-bit parity or clear channel), the cable length

(0 – 450 feet or 450 – 900 feet), and the cell payload scrambling mode (enabled or disabled).

— For an E3 trunk port, specify the cable length (0 – 400 feet, 300 – 1000 feet, 800 – 1300

feet, or 1100 – 1900 feet) and the cell payload scrambling mode (enabled or disabled).

— For an OC-3c trunk port, specify the clocking mode (internal or external).

2-16 LightStream 2020 Installation Guide

For more information about trunk port conﬁguration, refer to the LightStream 2020 Conﬁguration Guide.

Attaching a Terminal to a Console Port

This section explains how to attach a VT100 terminal (or equivalent) to the console port of a Release 2 switch card and how to match the baud rate between them.

Background Information

Prior to Release 2.1 of the LS2020 platform software, the TCS hub code for a Release 2 switch card (SC2) supported baud rate selection for both the console and modem ports through what was called the “BREAK” detection mechanism (also referred to as the “auto-baud” or “pseudo-auto-baud” mechanism). Use of this mechanism, which involv ed multiple acti vations of the Breakkey for baud rate selection, is no longer supported. Under this previous scheme, the midplane EEPR OM locations used to maintain the console and modem port baud rates were “reserved” and, hence, not initialized with appropriate default values.

Now, when new TCS hub code is installed in a Release 2 switch card that has not had these “reserved” locations initialized, the new code ev aluates the contents of these EEPROM locations and initializes them, if required, with appropriate default values. See the section below entitled “Setting Console/Modem Baud Rates through TCS Hub Commands” for these default values and the order of precedence for other possible baud rates for the console and modem ports.

Basic LS2020 Configuration Tasks

Setting Console/Modem Baud Rates through TCS Hub Commands

T o detect and set baud rates for the console and modem ports for Release 2 switch cards, you use the TCS hub show and set commands, respectively. These commands interpret and manipulate the contents of speciﬁc ﬁelds in the midplane EEPROM used for storing initialized baud rates for the console and modem ports.

Note Baud rate detection and selection for the console and modem ports apply only to Release 2

switch cards.

The general form of the TCS hub show command for baud rate detection is outlined below:

TCS hub<<A or B>> show <sa | sb> <console | modem> baudrate

where:

TCS hub<<A or B>> Is the TCS hub prompt for the switch card (either switch card A or B, as

appropriate)

show Is the command that operates in conjunction with command arguments to

display the baud rate for the speciﬁed switch and the speciﬁed port

<sa | sb> Denotes that the show command is to apply to switch card A or B,

whichever is speciﬁed

<console | modem> Denotes that the show command is to apply to the console port or the

modem port, whichever is speciﬁed

baudrate Displays the baud rate for the speciﬁed port

The general form of the TCS hub set command for baud rate selection is outlined below:

Hardware Installation 2-17

Basic LS2020 Configuration Tasks

TCS hub<<A or B>> set <sa | sb> <console | modem> baudrate <rate>

where:

TCS hub<<A or B>> Is the TCS hub prompt for the switch card (either switch card A or B, as

set Is the command that operates in conjunction with command arguments to

<sa | sb> Denotes that theset command is to apply to switch card A or B, whichever

<console | modem> Denotes that theset command is to apply to the console port or the modem

baudrate Indicates that the set command is to set the baud rate for the speciﬁed port <rate> Deﬁnes the actual baud rate for the speciﬁed port

For the Modem Port:

The following is the order of precedence of the baud rate for the modem port on a Release 2 switch card:

1 2400 (default value)

appropriate)

set the baud rate for the speciﬁed switch and the speciﬁed port

is speciﬁed

port, whichever is speciﬁed

2 9600

For the Console Port:

The following is the order of precedence of the baud rate for the console port on a Release 2 switch card:

1 9600 (default value) 2 19200 3 2400 4 1200 5 4800 6 38400 7 300

Note The console port baud rate can be changed at any time, but the change will take effect only

on powerup of the LS2020 chassis or a reset of the applicable switch card. Similarly , the modem port baud rate can be changed at any time, but the change will take ef fect only on powerup of the LS2020 chassis, on a reset of the applicable switch card, or when the modem port is reinitialized by means of the TCS hub init command.

Changing Modem Port Baud Rate if Modem Connection Cannot Be Established

If the modem port on a Release 2 switch card (SC2) is initialized with a baud rate other than that with which the modem can operate, you can change the modem port baud rate through either of two methods, whichever is appropriate for your LS2020 conﬁguration:

• Method 1, changing modem baud rate locally—This method requires access to the local

console of your LS2020 switch.

2-18 LightStream 2020 Installation Guide

Basic LS2020 Configuration Tasks

• Method 2, changing modem baud rate through use of redundant components—With this

method, the assumption is made that the local console terminal is not available (for example, if a software installation or upgrade is being done remotely). The assumption is also made that your LS2020 chassis is equipped with redundant Release 2 switch cards and modems, and that you have the ability to dial into the LS2020 chassis using the other switch card and modem.

Method 1

If you have access to the local console, perform the following procedure to match the modem port baud rate:

Step 1 Issue the set command from the console:

set {sa | sb} modem baudrate {2400 | 9600}

where {sa | sb} represents either Release 2 switch card A or B, as appropriate, and

{2400 | 9600} represents the available choices in matching the modem port baud rate.

Step 2 Issue the init command at the TCS hub prompt:

init {sa | sb} modem

This command initializes the modem port on the speciﬁed switch card with the selected baud rate.

Method 2

If you do not have access to the local console, but you can dial into the LS2020 chassis by means of a switch card, perform the following procedure to match the baud rate of the desired modem port:

Step 1 Dial in to the LS2020 chassis and determine the address of the switch card to which the

desired modem is attached, that is, the modem for which you are attempting to match the baud rate.

Step 2 Issue the set command at the TCS hub prompt:

set {sa | sb} modem baudrate {2400 | 9600}

In this command, specify the switch card having the non-matching baud rate. For example, if you have dialed into the LS2020 chassis through switch card A, specify sb in the set command; if you have dialed into the chassis through switch card B, specify sa in the set command. Finally, specify the desired baud rate for the modem port.

Step 3 Issue the init command at the TCS hub prompt:

init {sa | sb} modem

Again, as in Step 2 above, specify the switch card having the non-matching baud rate. This command initializes the modem port on the switch card with the speciﬁed baud rate.

Attaching a Terminal and Matching the Baud Rate

Figure 5-2 in Chapter 5, “Additional Components” illustrates the console/ modem assembly for a switch card. This assembly is inserted in the access (rear) side of the LS2020 chassis opposite a corresponding switch card. This assembly provides the means for attaching a terminal or a modem to your LS2020 switch.

T o attach the terminal cable to the console port and to match the terminal and the console port baud rates, perform the following procedure:

Step 1 Connect the cable for the VT100-compatible terminal to the console (CNSL) port on the

console/modem assembly.

Hardware Installation 2-19

Basic LS2020 Configuration Tasks

The switch card slots in the front of the LS2020 chassis are labeled A and B, as are the corresponding slots for the console/modem assembly bulkhead(s) in the rear of the LS2020 chassis. If the primary TCS hub is on switch card A, connect the terminal cable to the console port of the bulkhead in rear slot A; similarly, if the primary TCS hub is on switch card B, connect the terminal cable to the console port of the bulkhead in rear slot B.

Note If your LS2020 chassis contains two switch cards, connect the terminal cable to the console

port on the console/modem assembly for the switch card with the primary TCS hub. To identify this card, examine the green TCS SEL LED on each switch card. The card with the TCS SEL LED lit

is the primary TCS hub.

Step 2 Press Return on the terminal keyboard.

If the TCS hub<<A or B>> prompt appears, or if some other prompt appears (see the note below), after you press Return, the prompt signiﬁes agreement between the terminal baud rate and the console port baud rate and indicates that the terminal is properly attached.

Note If the baud rates match, the system may respond with other than the TCS hub<<A or B>>

prompt, depending on the card to which a connection exists. For example, if you had previously established a connection to an NP card via the TCS connect command, the system would respond with the bash (#) prompt, rather than the TCS hub<<A or B>> prompt. The appearance of any valid system prompt on the terminal screen after Return key activation signiﬁes baud rate agreement.

When the system veriﬁes itself as being responsive (through the return of an appropriate prompt), you can make the terminal fully operational in your LS2020 environment by connecting it to the NP . T o do so, proceed directly to the section belo w entitled “Connecting the Terminal to the NP.”

However , if the system does not respond at all, or if screen output is g arbled after you press Return, one of the following conditions may pertain:

• An apparent mismatch of the terminal and the console port baud rates exists. Such a

mismatch may occur, for example, if the console port has been initialized previously with a baud rate different from that of the terminal.

In this case, you must attempt to achieve a baud rate match by continuing with Step 4 below.

• A connection may exist to a non-operational card or a card that has been physically

removed from the system, but to which a logical connection still exists. In this case, proceed with Step 3.

Step 3 Issue the character sequence‘. (back quote plus dot, that is, left single quote plus period)

at the terminal keyboard and press Return. This action breaks the connection which may exist between the switch card and any nonoperational or missing card.

If a valid system prompt does not appear following Return key activation, a baud rate mismatch still exists and you must continue with Step 4.

Step 4 For baud rate matching purposes, your LS2020 chassis must be equipped with at least one

switch card and a terminal.

2-20 LightStream 2020 Installation Guide

Basic LS2020 Configuration Tasks

Set the terminal to a new baud rate, using the order of precedence deﬁned for the console port in the section above entitled “Setting Console/Modem Baud Rates through TCS Hub Commands.”

Step 5 Press Return on the terminal keyboard. Step 6 If the baud rates match after you press Return, the TCS hub prompt is displayed, indicating

that the terminal is properly attached. Proceed to the section below entitled “Connecting the Terminal to the NP.” However, if the TCS hub prompt is not displayed, you must repeat Step 4 and Step 5 until

a match with one of the deﬁned baud rates is achieved. If the terminal does NOT support one of the deﬁned console port baud rates, proceed with

Step 7. If you cycle through all the possible console baud rates without achieving a match, an error

condition exists. In this case, contact your Cisco Systems customer support representative.

Step 7 For baud rate selection, this step requires that your LS2020 be equipped with a modem

attached to the same switch as the terminal and that you have the ability to dial in to the LS2020 chassis.

If you can dial in to the LS2020 chassis, do so and continue with Step 8. If you are unable to dial in to the chassis, skip to Step 10.

Step 8 Use the TCS hub set <switch slot> console baudrate <rate> command to set the

baud rate of the console port to agree with that of the terminal you are attempting to attach.

Step 9 Reset the applicable switch card.

This action reinitializes the console port to the baud rate selected in Step 8. Proceed to the section below entitled “Connecting the Terminal to the NP.”

Step 10 For baud rate selection, this step requires that your LS2020 chassis be equipped with two

switch cards. It also assumes that you can communicate with the switch card that currently needs no baud rate adjustment.

Dial in to this card via its modem port or use the terminal attached to its console port to set the baud rate, as instructed in Step 11.

However, if your LS2020 chassis does NOT contain redundant switch cards, or if neither switch card is accessible via its console or modem port, an error condition exists. In this case, contact your Cisco Systems customer support representative.

Step 11 Use the TCS hub set <“other” switch slot> console baudrate <rate> command to

set the console port baud rate for the “other” switch card to agree with the baud rate of the terminal you are attempting to attach.

Step 12 Reset the “other” switch card manipulated in Step 11 above.

This action reinitializes the console port to the baud rate selected in Step 11. Proceed to the section below entitled “Connecting the Terminal to the NP.”

Connecting the Terminal to the NP

T o connect a terminal to the NP in your LS2020 switch, perform the procedure below . For simplicity , this procedure assumes that you are using the NP in slot 1.

Hardware Installation 2-21

Basic LS2020 Configuration Tasks

Note This procedure assumes that you have already attached a terminal to the Release 2 switch

card, as described in the preceding section entitled “Attaching a Terminal and Matching the Baud Rate.”

Step 1 Issue the following command at the TCS hub prompt to reset the NP to a running state:

TCS hub<<A>> reset 1

Step 2 Issue the following command at the TCS hub prompt to connect to the NP that you want to

conﬁgure:

TCS hub<<A>> connect 1

Step 3 When you connect to the NP, part or all of the follo wing countdo wn sequence is displayed

on your screen. Do not press Return; allow the boot sequence to continue.

System will boot in 5 seconds: hit <RETURN> to interrupt. System will boot in 4 seconds: hit <RETURN> to interrupt. System will boot in 3 seconds: hit <RETURN> to interrupt. System will boot in 2 seconds: hit <RETURN> to interrupt. System will boot in 1 seconds: hit <RETURN> to interrupt.

The screen displays for the boot sequence then continue as shown in Step 1 in the section “Entering Conﬁguration Data” later in this chapter. However, before proceeding with the entry of required conﬁguration data, note the following special consideration about running conﬁguration scripts.

Special Consideration: Running Scripts Separately

When you enter conﬁguration data, two scripts are inv oked automatically that prompt you for basic conﬁguration information (see bullets below). If you make a mistake entering information in response to script prompts, you can run the scripts again separately . To do so, enter the name of the script you want to run at the bash# (root) prompt or the single-user ($) prompt.

• bin/settimezoneinfo—Sets the time, date, daylight savings method, and time zone.

• usr/app/base/bin/setsnmpconﬁg—Sets the host name, the IP address, the Ethernet IP address,

and the default router IP address. Also sets up trunk ports so that a complete conﬁguration can be downloaded from the NMS to a target LS2020 node.

Note These conﬁguration scripts are intended for use only during the installation process.

When you run these scripts from the command line, they behave very much as the y do in the scripted conﬁguration procedure. However, one difference to note is that the setsnmpconﬁg command checks for the presence of conﬁguration ﬁles. (Normally, these ﬁles are not present during a typical installation of a new LS2020 switch.) If the system ﬁnds such ﬁles, it asks if you want to continue, as shown below:

Configuration information already exists. If you continue, the configuration information on this network node will be destroyed by overwriting the following files: /usr/app/base/config/configure.netdb /usr/app/base/config/mma.db.dir /usr/app/base/config/mma.db.pag Continue? (y/n) [n]

2-22 LightStream 2020 Installation Guide

Caution If you answer y (yes) to this query, the system overwrites the existing conﬁguration ﬁles

for this particular LS2020 node, effectively deleting the ﬁles.

If conﬁguration ﬁles are present and you choose not to overwrite them, the setsnmpconﬁg script cannot continue. Instead, the script exits and returns you to the command line.

If conﬁguration ﬁles are not present, or if theyare present and you choose to overwrite them, a script prompts you to enter network conﬁguration information, as outlined in the following section, “Entering Conﬁguration Data.”

Entering Conﬁguration Data

In this procedure, a script prompts you to enter basis LS2020 conﬁguration information. In performing this procedure, it is assumed that you have already initiated the boot sequence, as previously described in the section “Connecting the Terminal to the NP.”

Note If a problem occurs with the LS2020 hard disk or the platform software, an error message is

displayed instead of the system output shown in Step 1 below. In this case, refer to Appendix B Software Reinstallation.

If you conﬁrm that the conﬁguration data you have entered in this step is correct by responding Y to this query, the script continues with the trunk port conﬁguration query below.

On the other hand, if you wish to change any conﬁguration data, answer “N” at the chassis and network processor information query and repeat this step in its entirety. You will be prompted by the conﬁguration script to re-enter all the applicable network management information for your LS2020 switch.

Similarly, if you respondN to the above trunk port conﬁguration query , the system reports that it is creating a minimum conﬁguration database and that you have completed the basic conﬁguration procedure.

If you respond “Y” to the trunk port conﬁguration query, proceed with Step 6.

If you conﬁrm that the conﬁguration data you have entered in this step is correct by responding Y to this query, the script continues with the trunk port conﬁguration query below.

Hardware Installation 2-27

Basic LS2020 Configuration Tasks

Configure trunk port information (Y/N) [N] N Creating minimum configuration database...done.

Similarly, if you respondN to the above trunk port conﬁguration query, the system reports that it is creating a minimum conﬁguration database and that you have completed the basic conﬁguration procedure.

However , if you respondY to the trunk port conﬁguration query , proceed with Step 6 below .

Step 6 If your LS2020 switch is not directly attached to a LAN to which the NMS is also attached,

you must conﬁgure a trunk so that SNMP conﬁguration trafﬁc can ﬂow between the new LS2020 switch, the LS2020 network at large, and the LS2020 switch attached to the NMS. In operational terms, the trunk port will be used to load a full conﬁguration over the LS2020 network.

The trunk port conﬁguration parameters you specify depend on the type of trunk port that you intend to use for SNMP conﬁguration trafﬁc. For detailed information about the various trunk port conﬁguration parameters supported by the LS2020 switch, refer to the chapter in the LightStream 2020 Conﬁguration Guide that describes “port attributes.”

However, for the sake of example, a trunk port for a low-speed card has been selected to demonstrate the trunk port conﬁguration procedure. In this particular case, proceed as directed by the following conﬁguration script:

Basic LS2020 Configuration Tasks

As with chassis information, if you answer N to the port conﬁrmation prompt, you will be prompted to re-enter all the trunk port information, beginning with the “Trunk Card

Type

.”

If you answer Y, you will be queried if you want to conﬁgure an additional trunk, as shown below:

Configure additional trunk port information (Y/N)? [N] Y

If you respond Y to this query, repeat this procedure to conﬁgure additional trunk ports. If you respond N to this query, the system responds with the following message:

Creating minimum configuration database...done. A trunk configuration CLI script has been written to /tmp/trunkconfig.cli

The message means that the system has created a minimum LS2020 conﬁguration. It also signiﬁes that the system is loading the line cards, starting the LS2020 platform software, and starting the neighborhood discovery process.

At this point, the login prompt appears. You can then continue with Step 7.

Step 7 If you have previously conﬁgured trunk port information as part of the basic conﬁguration

procedure, you must apply that information to the platform software.

Note T o apply trunk port information to the platform software, you must ﬁrst wait for the line cards

(which incorporate the trunk ports you need to conﬁgure) to come up. A line card is signaled as being up when the NDD_3 trap for that card appears on the console, as shown in the example below.

(OPER) NDD_3 at 03/05/96 10:56:04 EDT (03/05/96 14:54:04 GMT) Line Card ls2020:5 (MS-TR) up.

Next, log in to the system and start the CLI using the oper or npadmin account, as shown in the example below:

user name: npadmin password: <password> Return

When you log into the oper or npadmin account, the CLI starts automatically, ﬁrst presenting the CLI banner on the console and then the CLI prompt, as shown in the example below:

When the CLI prompt appears, enter the CLI protected mode, as shown below:

cli> protected Enter Password: <password> Return *cli>

Next, invoke the CLI conﬁguration trunk script using the source command, as shown below:

*cli> source “/tmp/trunkconfig.cli”

This command applies the trunk conﬁguration to the trunk ports you have conﬁgured. Note that additional traps may be generated at this time to signal the changes in the status of the trunk ports. Such trap messages are normal.

Step 8 If you are installing a new LS2020 switch with two NPs, return to the earlier section

“Connecting the T erminal to the NP.” Repeat the conﬁguration procedures from that point to conﬁgure the second NP for your LS2020 switch.

Upon completion of the basic conﬁguration procedures for the NP(s) in your LS2020 chassis, continue as described in the following section, “How to Proceed.”

How to Proceed

This section describes actions you should take after installing a new LS2020 switch.

Running Diagnostics

T o ensure that the ne wly installed LS2020 switch is working properly, run the hardware diagnostics described in the LightStream 2020 Hardware Reference & Troubleshooting Guide.

Starting Maintenance Log

Keep a maintenance log for each LS2020 switch in your network. At a minimum, you should record the following information:

• The node name and its IP address

• Passwords

• The date and description of every maintenance or repair procedure performed on the LS2020

switch, such as replacement of a faulty line card, power tray, and so forth.

• The chassis ID, modem initialization string, and modem password, all of which are stored in

EEPROMs on the midplane. If the current EEPROMs or the midplane are replaced, you will need to enter the chassis ID and

modem information into the EEPROMs on the new midplane. See the LightStream 2020 Hardware Reference & Troubleshooting Guide for instructions on ﬁnding the chassis ID and modem information.

You are also advised to record any unusual LS2020 behavior. The maintenance log can be highly useful in identifying and correcting chronic or intermittent LS2020 operational problems.

Installing StreamView Network Management Software

You must install the CLI, the StreamView conﬁgurator, monitor , and topology map modules , and the private MIB database on the NMS that you will be using to manage your LS2020 network. The chapter “Installing Network Management Software Applications” presents the necessart procedures for installing the network management software.

Setting Up Network Environment

The chapter “Setup Procedures” presents procedures and options that enable you to tailor your network environment to your particular operating requirements. For example, you can enable the security mechanism that prevents unauthorized network access. Also, you can change operational parameters, such as the default SNMP community name(s) and the default trap delivery address(es).

You should read the chapter “Setup Procedures” and perform any applicable procedures therein before activating your LS2020 switch in the network.

Conﬁguring the Network

The StreamView LS2020 conﬁgurator is used to create a global conﬁguration database for your LS2020 network and to load appropriate conﬁguration information into each LS2020 switch in the network.

For detailed information about these high-level procedures, see theLightStream 2020 Conﬁguration

Guide.

Backing Up Distribution Diskettes

By default, LS2020 chassis (platform) software is installed at the factory on the hard disk prior to shipment of the unit to a customer site. However, if you come into possession of distribution diskettes for a new LS2020 software release and you are concerned about how carefully they may be handled and stored, you should back them up before proceeding with any new software installation.

In the following procedures, it is assumed that you have access to a PC running DOS 5.0 (or later) and which supports at least one 1.44 MB ﬂoppy disk drive. It is also assumed that you ha ve a supply of at least 15 blank, DOS-formatted 1.44 MB diskettes.

Basic LS2020 Configuration Tasks

Note Using the diskcopy /v command in this procedure, you can verify the correctness of the copy

operation. Y ou can also use thediskcomp command to verify the copy operation. Refer to your DOS documentation for additional information about these commands. Do not use the dir command to display the names of ﬁles on the distribution diskettes. There is no FAT (DOS ﬁle allocation table) on LS2020 distribution diskettes; thus, there can be no FAT on backup diskettes. If you enter dir a: or dir b: in an attempt to display distribution diskette ﬁles, DOS responds with a read error message.

If Your PC Has Two 1.44-MB Floppy Disk Drives

To back up each LS2020 software distribution diskette, perform the following steps:

Step 1 Insert the ﬁrst distribution (source) diskette in ﬂoppy disk drive A. Step 2 Insert a blank, formatted (destination) diskette in drive B. Step 3 Enter the following command at the DOS prompt:

C:\> diskcopy a: b: /v

Step 4 DOS then copies the data from drive A to the backup diskette in drive B. Step 5 At the conclusion of the ﬁrst copy operation, DOS asks if you want to perform an additional

copy operation.

Step 6 Press Y and insert the next distribution (source) diskette into drive A. Step 7 Continue copy operations until all the distribution diskettes are backed up.

Basic LS2020 Configuration Tasks

If Your PC Has One 1.44-MB Floppy Disk Drive

To copy each LS2020 software distribution diskette, perform the following steps:

Step 1 Insert the ﬁrst distribution (source) diskette into ﬂoppy disk drive A. (This procedure

assumes that you have conﬁgured your ﬂoppy disk as drive A.)

Step 2 Enter the following command at the DOS prompt:

C:\> diskcopy a: a: /v

Step 3 DOS reads the contents of the ﬁrst source diskette into memory. When DOS prompts you

to do so, remove the ﬁrst distribution diskette and insert a blank, formatted (destination) diskette into ﬂoppy drive A.

Step 4 DOS copies the data from memory onto the backup (destination) diskette. When DOS

prompts you to do so, remove the ﬁrst backup diskette and insert the next distribution diskette in the series into ﬂoppy disk drive A.

Step 5 Alternate Step 3 and Step 4 in response to DOS prompts until you have copied the entire

set of distribution diskettes.
