Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. For network applications that require routing between dissimilar network types, you can attach this switch directly to a router. As a general rule the length of Gigabit fiber optic cable for a single switched link should not exceed 550 m (1805 ft) for 1000BASE-SX multimode fiber or 5 km (16404 ft) for 1000BASE-LX single-mode fiber. However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-8 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerSwitch 10/100/1000 units can be mounted in a standard 19-inch equipment rack or on a flat surface. The site should: · · be at the center of all the devices you want to link and near a power outlet. be able to maintain its temperature within 0° to 50° C (32 to 122° F) and its humidity within 10% to 90%, non-condensing provide adequate space (approximately two inches) on all sides for proper air flow be accessible for installing, cabling and maintaining the devices allow the status LEDs to be clearly visible · · · Make sure twisted-pair cable is always routed away from power lines, fluorescent lighting fixtures and other sources of electrical interference, such as radios, transmitters, etc. Make sure that a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz, is within 2. 44 m (8 feet) of each device and is powered from an independent circuit breaker. As with any equipment, using a filter or surge suppressor is recommended. 3-1 INSTALLING THE SWITCH Equipment Checklist After unpacking the TigerSwitch 10/100, check the contents to be sure you have received all the components. Then, before beginning the installation, be sure you have all other necessary installation equipment. Package Contents TigerSwitch 10/100/1000 unit, SMC8612T Four adhesive foot pads Bracket Mounting Kit containing two brackets and eight screws for attaching the brackets to the switch Power Cord--either US, Continental Europe or UK RS-232 console cable This Installation Guide Management Guide SMC Warranty Registration Card--be sure to complete and return to SMC Optional Rack-Mounting Equipment If you plan to rack-mount the switch, be sure to have the following equipment available: Four mounting screws for each device you plan to install in a rack--these are not included A screwdriver (Phillips or flathead, depending on the type of screws used) 3-2 MOUNTING Mounting A TigerSwitch 10/100/1000 unit can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Rack Mounting Before rack mounting the switch, pay particular attention to the following factors: Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range. (See page C-2. ) Mechanical Loading: Do not place any equipment on top of a rack-mounted unit Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded. Particular attention should be given to supply connections other than direct connections to the mains. 3-3 INSTALLING THE SWITCH To rack-mount devices: 1. Attach the brackets to the device using the screws provided in the Bracket Mounting Kit. 1 3 5 7 9 11 2 4 6 8 10 12 10 11 12 9 Figure 3-1.

If installing a single switch only, turn to "Connecting to a Power Source" at the end of this chapter. If installing multiple switches, mount them in the rack, one below the other, in any order. If also installing RPUs, mount them in the rack below the other devices. Desktop or Shelf Mounting 1. Attach the four adhesive feet to the bottom of the first switch. Figure 3-3. [. . . ] Ethernet A network communication system developed and standardized by DEC, Intel, and Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. The successor IEEE 802. 3 standard provides for integration into the OSI model and extends the physical layer and media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable. Fast Ethernet A 100 Mbps network communication system based on Ethernet and the CSMA/CD access method. Fast Ethernet Switch Device that provides a full 100 Mbps bandwidth (or either 10 or 100 Mbps bandwidth with Auto-Negotiation) to each port (LAN segment). Glossary-2 Full Duplex Transmission method that allows switch and network card to transmit and receive concurrently, effectively doubling the bandwidth of that link. [. . . ]
