Initially, there are 24 untagged ports you can select; this number decreases as you use untagged ports in your VLANs. Deleting Ports The following procedure describes how to delete ports from a VLAN. Since there is no precautionary message that appears before you delete a VLAN port, be sure you want to delete the port before you begin. From the screen at the bottom of page 35, use the Up Arrow and Down Arrow keys to highlight the port you want to delete. The port is deleted. · To select an individual port, highlight it and press Enter. An asterisk will appear next to each port you select (to deselect it, press Enter again to remove the asterisk).

[. . . ] As the new Gigabit standard gradually integrates into existing networks, current computer applications will enjoy faster access time for network data, hardware, and Internet connections. Fiber Optic Cabling Fiber optic cabling is made from flexible, optically efficient strands of glass and coated with a layer of rubber tubing, fiber optics use photons of light instead of electrons to send and receive data. Although fiber is physically capable of carrying tetrabits of data per second, the signaling hardware currently on the market can handle no more than a few gigabits of data per second. The most commonly used fiber optic cable is multi-mode fiber cable (MMF), with a 62. 5 micron fiber optic core. Single-mode fiber cabling is somewhat more efficient than multi-mode but far more expensive, due to its smaller optic core that helps retain the intensity of traveling light signals. [. . . ]
