A set of stacked hubs, which must be stacked with a stacking cable, counts as one hub or node on the network. • In Fast Ethernet, an Ethernet Switch acts as a repeater, regenerating data sig- nals before passing them on to the next device. Hubs cannot act as repeaters.
Configuration A shows one possible way to set up an Ethernet Switch in a Fast Ethernet environment. Note that an Ethernet Switch requires UTP Category 5 network cabling for all its connections, like all Fast Ethernet network hardware. All of the workstations below can access all resources on the network - 10Mbps users can access the 100Mbps nodes, and vice versa.
Powering On an Ethernet Switch Plug in an Ethernet Switch's AC power cable. The Switch will first run a diag- nostic Self-Test, which just takes a few seconds. After the test, the Power LED will light up to indicate that the unit is powered on. As each node is powered on, the corresponding port’s Link/Activity (Link/Act) LED will light up.
(models EF3116 & EF3124 ONLY) Important: Fiber Optic Modules will only function with model numbers: EF3116 and EF3124. If you are not sure of the Switch’s model number, make sure there is a fiber optic module port in the front of the Switch. If it does not have a fiber optic module port, your Switch will not function with Fiber Optic Modules.
10Mbps to the higher Fast Ethernet speed of 100Mbps requires virtually no effort with the right piece of equipment. All it takes is an Ethernet Switch to coordinate your network hardware, and you’re ready to run a top-notch system.

Switches also feature full duplex data transfer, meaning that all computers on the switch can “talk” to the switch at the same time. Plus, switches are able to send and receive data simultaneously to all connections, whereas a hub cannot.

Port - A pathway into and out of the computer or a network device such as a switch or router. For example, the serial and parallel ports on a personal com- puter are external sockets for plugging in communications lines, modems and printers.

STP (Shielded Twisted Pair) - Telephone wire that is wrapped in a metal sheath to eliminate external interference. Switch - 1. A data switch connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connections in an electrical cir- cuit.
