[. . . ] 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. As a general rule the length of fiber optic cable for a single switched 100BASE-FX link should not exceed 2 km (1. 24 miles) for multimode fiber or 20 km (2. 43 miles) for single-mode fiber. However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-7 NETWORK PLANNING 2-8 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerStack III 10/100 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 TigerStack III 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 TigerStack III 10/100 unit, SMC6824M Four adhesive foot pads Bracket Mounting Kit containing two brackets and four 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 TigerStack III 10/100 unit can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Installing Optional Modules: Before mounting the switch, be sure you install any optional modules. If you have purchased optional slide-in 1000BASE-T, 100BASE-FX, or 1000BASE-X (GBIC) media expansion modules, install these modules now, following the instructions "Installing an Optional Module into the Switch" on page 3-4. . 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. Figure 3-1. Mount the device in the rack, using four rack-mounting screws (not provided). Figure 3-2. 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. 3-4 MOUNTING Desktop or Shelf Mounting 1. Attach the four adhesive feet to the bottom of the first switch. Figure 3-3. Set the device on a flat surface near an AC power source, making sure there are at least two inches of space on all sides for proper air flow. If installing a single switch only, go to "Connecting to a Power Source" at the end of this chapter. If installing multiple switches, attach four adhesive feet to each one. [. . . ] Collision A condition in which packets transmitted over the cable interfere with each other. CSMA/CD Carrier Sense Multiple Access/Collision Detect is the communication method employed by Ethernet and Fast Ethernet. End Station A workstation, server, or other device that does not act as a network interconnection. Glossary-2 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.
