3. Basic LS2020 Configuration Tasks 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 involved multiple activations of the Break key for baud rate selection is no longer supported Under this previous scheme the midplane EEPROM 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 evaluates 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 Se
4. Configure additional trunk port information Y N N Y If you respond v 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 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 To 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 npp_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 1s2020 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 pre

6. 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 amp 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
7. 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 spe
