The miniGBIC ports are compatible with two types of modules, 850 nm and 1310 nm. Back Panel Port Figure 2-2 Figure 2-1 The power port is located on the back panel of the Switch. [. . . ] 1000Base-T - Provides half-duplex and full-duplex 1000Mbps Ethernet service over Category 5 links as defined by ANSI/TIA/EIA-568-A. Topology rules for 1000Base-T are the same as those used for 100BaseT. Category 5 link lengths are limited to 100 meters by the ANSI/TIA/EIA-568-A cabling standard. Auto MDI/MDI-X - On a network hub or switch, an auto MDI/MDI-X port automatically senses if it needs to act as a MDI or MDI-X port. The autoMDI/MDI-X capability eliminates the need for crossover cables. For example, Ethernet 10/100 cards, hubs and switches can determine the highest speed of the node they are connected to and adjust their transmission rate accordingly. CAT 5 - ANSI/EIA (American National Standards Institute/Electronic Industries Association) Standard 568 is one of several standards that specify "categories" (the singular is commonly referred to as "CAT") of twisted pair cabling systems (wires, junctions, and connectors) in terms of the data rates that they can sustain. CAT 5 cable has a maximum throughput of 100 Mbps and is usually utilized for 100BaseTX networks. CAT 5e - The additional cabling performance parameters of return loss and farend crosstalk (FEXT) specified for 1000BASE-T and not specified for 10BASE-T and 100BASE-TX are related to differences in the signaling implementation. 10BASE-T and 100BASE-TX signaling is unidirectional-signals are transmitted in one direction on a single wire pair. In contrast, Gigabit Ethernet is bi-directional-signals are transmitted simultaneously in both directions on the same wire pair; that is, both the transmit and receive pair occupy the same wire pair. Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Forms the underlying transport vehicle used by several upper-level protocols, including TCP/IP and XNS. For rack-mounting, the Switch has four mounting holes located on each side. Place the Switch in the rack, and secure it with screws. Congratulations!The installation of the 24-Port 10/100 + 2-Port Gigabit Switch + 2 miniGBIC is complete. 6 7 Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet CSMA/CD network access method. Hub - The device that serves as the central location for attaching wires from workstations. Can be passive, where there is no amplification of the signals; or active, where the hubs are used like repeaters to provide an extension of the cable that connects to a workstation. Mbps (Megabits per second) - One million bits per second; unit of measurement for data transmission. MDI (Medium Dependent Interface) - On a network hub or switch, a MDI port, also known as an uplink port, connects to another hub or switch using a straightthrough cable. MDI-X (Medium Dependent Interface Crossed) - On a network hub or switch, a MDI-X port connects to a computer using a straight-through cable. To connect a MDI-X port to another hub or switch, use a crossover cable. Network - A system that transmits any combination of voice, video and/or data between users. [. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which is found by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna Increase the separation between the equipment or devices Connect the equipment to an outlet other than the receiver's Consult a dealer or an experienced radio/TV technician for assistance Safety Notices Caution: To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Do not use this product near water, for example, in a wet basement or near a swimming pool. Industry Canada (Canada) This device complies with Canadian ICES-003 rule. [. . . ]
