Certificate of the Manufacturer/Importer It is hereby certified that the NETGEAR Model FSM726S Managed Stackable Switch has been suppressed in accordance with the conditions set out in the BMPT-AmtsblVfg 243/1991 and Vfg 46/1992. The operation of some equipment (for example, test transmitters) in accordance with the regulations may, however, be subject to certain restrictions. Federal Office for Telecommunications Approvals has been notified of the placing of this equipment on the market and has been granted the right to test the series for compliance with the regulations. Voluntary Control Council for Interference (VCCI) Statement This equipment is in the first category (information equipment to be used in commercial and/or industrial areas) and conforms to the standards set by the Voluntary Control Council for Interference by Data Processing Equipment and Electronic Office Machines that are aimed at preventing radio interference in commercial and/or industrial areas. [. . . ] The `hotkey' or letter in front of each menu option can also be typed to directly choose that option. As shown in Figure 6-3, there are six menu items to choose from: o System o Status o Set-Up o Tools o Security o Advanced To logout of the user interface, hit Ctrl-D at anytime during your telnet session. You will be brought back to the login screen (password enabled) or Main Menu (password disabled). Figure 6-3: Main Menu Page 32 of 110 Main Menu> System This screen displays the following: System uptime System Description System Name- user definable System Contact-user definable System Location-user definable MAC Address Figure 6-4: System Information Page 33 of 110 Main Menu> Status There are two sub-menus at Status menu, the Switch Statistics and MAC Address Table. Main Menu> Status >Statistics There are two sections in this screen. The Unit number at the top indicates the switch in the stack, and left-side Port-ID field allows you to choose a port to be observed. The central portion of the screen displays the basic statistics associated with the port, which is highlighted at the Port-ID field. Figure 6-5: Statistics Page 34 of 110 Main Menu> Status > MAC Address Table (Dynamic Addresses) The MAC Address lookup table allows you to view the dynamic MAC addresses that are currently in the address database. When addresses are in the database, the packets intended for those addresses are forwarded directly to those ports. You can filter out addresses in the table by port, VLAN, and/or MAC address by entering a value in those fields, and selecting `Query'. Figure 6-6: Address Manager: MAC Address Table Page 35 of 110 Main Menu> Set-Up There are two sub-menus at Set-Up menu, Port Configuration and IP Configuration. Main Menu> Set-Up> Port Configuration On this page, you can set up the port characteristics related to link operations (see Figure 6-7). To change, or toggle, between options, hit Ctrl-M to move the curser to the ports field and simply strike the space bar when the appropriate option is highlighted. The comments field is available for you to enter a description of the port. State The State field displays the Spanning Tree State of the port (Blocking, Listening, Learning, Forwarding, or Disabled). You can only observe the status of the ports; you cannot modify this field. Rate/Duplex field Offers the choice of Full-duplex, Half-duplex, or Auto negotiation. Enabling auto-negotiation on a port allows a port to sense the communication speed and negotiate the duplex mode (full duplex or half duplex) automatically. The port can auto-negotiate with any port that is compliant with IEEE 802. 3u. If the other port is not IEEE802. 3u compliant, the port will default to half-duplex, 10 Mbps mode. Flow control is a protocol that prevents packets from being dropped by reducing the amount of traffic to a level that can be accommodated. If enabled on both ends of a connection, it will prevent the sender from sending data until the receiver can accept it. Gigabit Ports For the two gigabit ports on each switch in the stack, the port type may be chosen. If so, the user must switch the port type from `GT' to `GB'. This can be done by hitting the space bar on the two letters next to the port number. [. . . ] All of these factors affect the performance of 1000BASE-T technology if not correctly implemented. The following sections are designed to act as a guide to correct cabling for 1000BASE-T. Page 108 of 110 Cabling The 1000BASE-T product is designed to operate over Category 5 cabling. To further enhance the operation, the cabling standards have been amended. The latest standard is Category 5e, which defines a higher level of link performance than is available with Category 5 cable. [. . . ]
