Placement Options for the 16-Port Switch There are three ways to physically install the 16-Port Switch: set the Switch on its four rubber feet, mount the Switch in a standard-sized, 1U high rack, or hang the Switch on a wall using its wall-mount slots. To rack mount the Switch, follow these instructions: 1. The Switch has four mounting holes on each side. Screw an included mounting bracket into each side. 2. Place the Switch in the rack, and secure the brackets with additional screws. To hang the Switch on a wall, follow these instructions: 1. The wall-mount slots are two crisscross slots on the Switch's bottom panel (see Figure 3-3). The distance between the two slots is 95 mm. Attach two screws to the wall, so that the Switch's wall-mount slots line up with the two screws. Figure 3-3 2. Maneuver the Switch so the screws are inserted into the two slots. Congratulations! The installation of the 16-Port 10/100/1000 Gigabit Switch is complete. Placement Options for the 24-Port Switch There are two ways to physically install the 24-Port Switch; set the Switch on its four rubber feet or mount the Switch in a standard-sized, 1U high rack. 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 10/100/1000 Gigabit Switch is complete. 6 Appendix A: Glossary 10BaseT - An Ethernet standard that uses twisted wire pairs. 100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of Category 5 UTP or STP wire. 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. Auto-negotiate - To automatically determine the correct settings. The term is often used with communications and networking. 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. Has a transfer rate of 10 Mbps. Forms the underlying transport vehicle used by several upper-level protocols, including TCP/IP and XNS. 7
