[. . . ] TE100-DX8 TE100-DX16 Ethernet/Fast Ethernet Dual-Speed Stackable Hub User's Guide TRENDware International, Inc. Rev. 01 (May 1998) 6ETHFE16. . 01 Printed In Taiwan RECYCLABLE FCC Warning This equipment has been tested and found to comply with the regulations for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with this user's guide, may cause harmful interference to radio communications. [. . . ] As mentioned earlier, stackable Class II hubs can be used to increase the number of available nodes in a collision domain. An entire hub stack counts as a single repeater. Hubs in this series are Class II devices. Introduction 7 Dual-Speed Stackable Hub User's Guide 2 2 UNPACKING AND SETUP This chapter provides information on the unpacking and initial installation of your hub stack. Unpacking Open the shipping carton of your hub and carefully unpack the contents. The carton should contain the following items: One Ethernet/Fast Ethernet dual-speed stackable hub One AC power cord, suitable for your area's electrical power connections One daisy-chaining cable Four rubber feet to be used for cushioning This User's Guide Inspect the hub and all accompanying items. If any item is damaged or missing, report the problem immediately to your network equipment dealer. Unpacking and Setup 9 Identifying External Components This section identifies all the major external components of the hub. Both the front and rear panels are shown, followed by a description of each panel feature. The indicator panel is described in detail in the next chapter. Front Panel The figure below shows the front panels of all hubs in the product family that includes your hub. The two at the top are sixteen-port units, the first with a built-in switching circuit and the second without such a circuit; the two at the bottom are eight-port units, the first with and the second without a built-in switching circuit. Identify your own hub's front panel in the figure before going on. 10 Unpacking and Setup Dual-Speed Stackable Hub User's Guide LED Indicator Panel Refer to the next chapter, Understanding Indicators, for detailed information about each of the hub's LED indicators. Twisted-pair Jacks Use these jacks to connect stations to the hub. These are MDIX (Medium-Dependent Interface, Cross-wired) jacks, which means you can use ordinary straight-through twisted-pair cables to connect user machines and servers to the hub through them. If you need to connect another device with an MDI-X jack, such as another hub or an Ethernet switch, you should use a crossover cable, or make the connection using the Uplink jack (described below). For more information about crossover connections, see the section entitled Crossover Cables on page 28. Uplink Jack The Uplink jack is an MDI-II jack, which means you can connect the hub (or a hub stack) to a device with an MDI-X port using an ordinary straight-through cable, making a crossover cable unnecessary. The port 1 1X jack and the Uplink jack are really the same port, except that their pinouts are different. Do not use both the port 1 1X jack and the Uplink jack at the same time. Unpacking and Setup 11 Rear Panel Daisy Chain IN Port When stacking your hub with one to four other hubs in the same series, this port should be connected to the Daisy Chain OUT port of the previous hub in the stack (usually placed immediately above it). A stack of five hubs can be created in this way. The first and last hubs in the stack use only one of the daisy-chaining ports, while the others use both. Daisy Chain OUT Port This port works in conjunction with the Daisy Chain IN port (see above). Connect this port to the Daisy Chain IN port of the next hub in the stack (usually placed immediately below it), using the enclosed daisy-chaining cable. Fan Provides air circulation and heat dissipation. AC Power Connector For the power cord. 12 Unpacking and Setup Dual-Speed Stackable Hub User's Guide Installing the Hub Installation The site where you install the hub stack may greatly affect its performance. [. . . ] Between any two end-stations in a collision domain, there may be up to three cable segments and two Class II hubs (or two hub stacks, or one hub and one stack). Hub-to-end-node Connections After the hub is properly installed, it can support up to eight or sixteen end-node connections. Making Connections 21 Each Fast Ethernet connection requires either a Category 5 UTP cable or a Type 1 STP cable. These cables can be up to 100 meters long. Each Ethernet connection requires a Category 3 or better UTP cable. It is recommended that you use Category 5 cabling for all connections in order to make it easier to transition all stations to 100 Mbps. [. . . ]
