To enable management through external ports, complete the following steps:1. Log on to the management module as described in the User’s Guide orCommand Line Interface Reference Guide for your advanced management module.If necessary, obtain the IP address of the management module from yoursystem administrator. The management-module window opens.2. Click I/O Module Tasks > Configuration and click the bay number thatcorresponds to the location of the switch that you installed.3. Click Advanced Configuration and make sure that external management isenabled.4. Click I/O Module Tasks > Admin/Power/Restart and make sure that theexternal ports are enabled for the switch that you installed.Configuring the switch through the Telnet interfaceNote: Telnet is disabled by default.The switch supports a command-line interface (CLI) that you can use to configureand control the switch over the network through the Telnet program. You can usethe CLI to perform many basic network-management functions. In addition, youcan configure the switch for management through an SNMP-basednetwork-management system. The following sections describe how to use theTelnet interface to access the switch, change its settings, and monitor its operation.Connecting to the switchIf you know the IP address for the switch and you have an existing networkconnection, you can use the Telnet program from an external management stationor the management module to access and control the switch. The managementstation and the switch must be on the same IP subnet. If you have to obtain the IPaddress for the switch or establish a network connection, contact your system ornetwork administrator. Be sure to use the correct IP address in the requiredcommand, as specified in “Accessing the main menu.”Accessing the main menuTo connect to the switch through the Telnet interface, complete the following steps:1. From a DOS command-line prompt, type telnet x and press Enter.where x is the IP address for the switch.2. If you do not have an assigned initial password, in the Password field, type thedefault password (PASSW0RD, spelled with a zero) and press Enter.Important: The apply command changes the currently active configuration. If youwant your change to persist beyond the next reboot of the switch, you must enterthe save command. This command stores the current switch configuration and allchanges in nonvolatile memory.For more information about configuring through the CLI, see the Lenovo ApplicationGuide for the switch.Configuring the switch through the serial-port interfaceThe mini-USB serial port provides basic communication through a terminalemulation program (such as Hyperterminal). Because messages from the power-onself-test (POST) and all initialization information are transmitted through the serialport, you can use the serial port to log in to the switch and access and configurethe internal switching firmware.20 1Gb Ethernet Scalable Switch: User's Guide
