[. . . ] The switches also support multiple spanning trees which allow VLAN groups to maintain a more stable path between all VLAN members. This can reduce the overall amount of protocol traffic crossing the network, and provide a shorter reconfiguration time if any link in the spanning tree fails.

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. As a general rule the length of fiber optic cable for a single switched link should not exceed: · · · 1000BASE-SX: 550 m (1805 ft) for MMF 1000BASE-LX: 5 km (3. 1 miles) for SMF 1000BASE-ZX: 100 km (62. 1 miles) for SMF However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment. 2-6 CHAPTER 3 INSTALLING THE SWITCH Selecting a Site TigerStack 10G 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 5% to 95%, 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 and transmitters. 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 Ethernet Cabling To ensure proper operation when installing the switches into a network, make sure that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T operation. Check the following criteria against the current installation of your network: Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better for 100BASE-TX, and Category 5e, 6 or better for 1000BASE-T. Protection from radio frequency interference emissions Electrical surge suppression Separation of electrical wires (switch related or other) and electromagnetic fields from data based network wiring Safe connections with no damaged cables, connectors or shields RJ-45 Connector Figure 3-1 RJ-45 Connections 3-2 EQUIPMENT CHECKLIST Equipment Checklist After unpacking the TigerStack 10G unit, 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 10G unit (SMC8724M or SMC8748M) 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) 3-3 INSTALLING THE SWITCH Mounting A TigerStack 10G 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. 3-4 MOUNTING To rack-mount devices: 1. Attach the brackets to the device using the screws provided in the Bracket Mounting Kit. 46 47 48 Mas ter Stac k ID Stack Stack Ma Link ster Powe RPU r 45 Modu le Diag 46 47 Cons ole 48 Figure 3-2 Attaching the Brackets 2.

[. . . ] CSMA/CD CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication method employed by Ethernet, Fast Ethernet, or Gigabit Ethernet. End Station A workstation, server, or other device that does not forward traffic. 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.
