Getting Started Physically install and cascade the hubs and power on the hub stack according to the directions in other parts of this manual. At this point, the hub stack is ready for use as an ordinary unmanaged repeater. The master hubs in the series come without IP addresses a ssigned (IP = 0. 0. 0. 0). Without a valid IP address, the master hub will show a POST error indication and repeatedly restart itself once every minute or so. If you want to manage your hub using a network management system, you will have to assign an IP a ddress to the hub. There are two different ways to configure the hub with a new address, as described below. Assigning an IP Address Using BOOTP If your Fast Ethernet network has a BOOTP (BOOTstrap Protocol) server, you can add the hub's Ethernet (MAC) address (which is printed on a sticker on the bottom of the hub, or you can obtain it using the master hub console interface), IP a ddress, subnet mask, and boot filename to your BOOTP server's configuration tables. The boot filename field of the hub's BOOTP configuration should contain the filename of a TE100-DM/DS series master hub boot configuration file accessible on your local TFTP (Trivial File Transfer Protocol) server. For more d etailed information about the boot configuration file contents, see Appendix C : Boot Configuration File of this manual. Assigning an IP Address Using the Diagnostic Port To assign an IP address manually, Master Hub Setup and Management 39 Dual-Speed Stackable Hubs User's Guide 1. Connect a VT-100 compatible terminal or a personal computer running a VT-100 compatible terminal emulation program to the DB-9 console port at the rear of the master hub. The cable should be an ordinary RS-232C cable. The terminal communications parameters should be set to 9600bps, 8 bits, no parity, and 1 stop bit. As the hub begins its boot process, hit Control-C to enter 3. Choose TCP/IP Parameters Configuration, and enter a valid IP address, network mask, and (optional) gateway router IP address. Choose SAVE and press <Enter> to let the changes take effect, and then choose EXIT. 4. If you will not be using TFTP to download a hub configuration file, choose Software Update and toggle the S oftware Update Control to "Disable" using the Space Bar. Choose Execute Bootstrap to restart the hub. You are now ready to use your TE100-DM/DS series hub stack, and to manage it from a network management station on your network. See the Stack Management User's Guide for more information about how to manage the stack using a network management program. Backup Master Function Within a TE100-DM/DS series hub stack, in addition to a master hub for management purposes, a standby backup master can also be installed. [. . . ] See "CSMA/CD. " Category 3, 4, 5 Collision 97 Index Collision Domain A section of a network isolated from other sections by a switch, bridge, or hub that detects and resolves collisions locally so that there is less impact on the entire network. A type of twisted-pair cable in which the wires at one end have been reversed in order to match pin-outs on a hub or switch. Carrier Sense Multiple Access with Collision Detection; a network communications protocol in which each trans-mission source (i. e. , station, server, switch, etc. ) monitors the main data channel for traffic before and during transmission, postponing transmission when the data channel is in use. Crossover Cable CSMA/CD D Duplex (full & half) The transmission of data over a network in both directions. Full-Duplex (FDX) is simultaneous transmission of data over a network channel in both directions. [. . . ]
