Cables can be shielded (screened) or unshielded. Cables must be Category 5 or above. 3Com recommends Category 5E cable for Gigabit connections. The maximum length you can use is 100 m (328 ft). Twisted Pair (TP) cable is very easy to use. To connect a TP cable, simply slot the connector into the relevant RJ-45 Port. When a connector is fully in, its latch locks into place. To disconnect the cable, push the connector’s latch in and remove it. When one end of a TP cable is connected to the Switch and the other end is connected to the network interface card of a workstation or other device, the Switch will automatically detect whether a straight-through or crossover cable is being used and will compensate if required. The units will then autonegotiate to determine the fastest possible link speed between them. This may take a few seconds and the outcome will be reflected in the LEDs on the front of the Switch. If the equipment connected to the Switch does not support autonegotiation or it has been disabled, it must be configured to operate in half duplex mode. Expanding Your Network You can increase the number of workstations and other devices that can connect to your network by adding OfficeConnect gateways and switches. You can connect a 10BASE-T, 100BASE-TX or 1000BASE-T OfficeConnect unit to each port of the Switch. The Switch has automatic MDI/MDIX functionality, and therefore does not require the Uplink/Normal switch associated with some OfficeConnect products. Simply plug in the cable, and the Switch will automatically detect which wiring practice has been followed, and will compensate accordingly. Checking Unit Connections When you have connected all your units, power on the units and the Switch. The Port Status LEDs for the ports you have used should be lit. If they are not, check your connections. 3 CONNECTING WORKSTATIONS Switching When a network of repeater hubs is in operation, any information that is sent by the workstation is passed around the whole network (regardless of the destination of the information). This can result in a lot of unnecessary traffic that can slow the network down. The Switch solves this problem because it "listens" to the network and automatically learns what workstations can be reached through its ports. It can then selectively pass on any information by transmitting the traffic from the relevant port only. This operation is called "switching". The Switch effectively divides up your network, localizing the network traffic and passing on traffic as necessary. If you have any high performance workstations that require a lot of bandwidth, connect them directly to the Switch. Traffic Prioritization The Switch has a built in feature to aid network performance at times of excessive load. It is called Priority Queuing. When a packet is received, the Switch will examine it to see if it has been priority encoded. If it has, the Switch will then read the priority level and determine whether it should be directed through the normal or high priority channel. This feature can be useful during excessive loads, for example, when one type of traffic may require priority over another. Connecting 10BASE-T/100BASE-TX/1000BASE-T Networks The ports can each be connected to a 10BASE-T/100BASE-TX/1000BASE-T network. If you have various connection speeds in your network, you can join them together using the Switch allowing all your workstations to communicate. For example, by connecting one of the ports to a server, all the workstations connected to the server can communicate with devices connected to the Switch, significantly increasing the size of your network. Alternatively, if for example you use a 10BASE-T/100BASE-TX network and want to improve network performance by introducing 1000BASE-T technology, the Switch protects the investment in your existing workstations because it maintains 10BASE-T/100BASE-TX connections to them. The Switch has been designed to aid you when detecting and solving possible problems with your network. These problems are rarely serious; the cause is usually a disconnected or damaged cable, or incorrect configuration. If this section does not solve your problem, contact your supplier for information on what to do next. Perform these actions first: • Ensure all network equipment is powered on. • Power each piece of network equipment off, wait about five seconds and then power each one on. CAUTION: Do not power the Switch off and then immediately on. Wait about five seconds between power cycles. Check the following symptoms and solutions: Power Status LED or Power Adapter OK LED not lit. Refer to the following table. Power Adapter OK LED Power Status LED Problem and Action On On All functioning correctly On Off The internal power supply has failed. Contact 3Com Technical Support for a replacement Switch. Off Off The power adapter or power adapter connection is faulty. Refer to "Replacement Power Adapters" below. Replacement Power Adapters If both the Power Adapter OK LED and Power Status LED are off, check your power adapter connection. If there is still no power, contact 3Com Technical Support and ask for a replacement power adapter. Please quote the power adapter part number, shown on the OfficeConnect power adapter you are currently using. Alternatively, quote the part number for your region: Part number Region 3C16740A US and Canada 3C16741A UK 3C16742A Europe and Middle East 3C16743A Japan 3C16744A Australasia (except Japan and Korea) 3C16745A South Africa 3C16747A Korea Only use the power adapter supplied with the Switch or a replaceme OfficeConnect power adapter. Do not use any other power adapter. Port Status LED not lit for a port that has a TP cable connected. After connection, it may take several seconds for the Port Status LEDs to illumina The Port Status LED should turn Green or Yellow for each port that is connected, depending on connection speed. The Duplex LED may or may n illuminate. Please refer to ‘About Your Switch’ for a full description of the LE If the Port Status LED is not lit after several seconds, ensure that the connected device is powered on, that the TP cable is not damaged and that is correctly inserted at both ends. You may find that a TP cable works when connected to the Switch, but tha does not if disconnected from the Switch and connected to another device This may be because the other device does not have the automatic MDI/MD feature. Alert LED continuously lit. Power down the Switch and disconnect all network connections. Wait about 5 seconds and power the Switch back up the Alert LED is continuously lit it can mean there is a problem with your Switch. The Switch will also light the Alert LED on if there is a high level of broadcast traffic or the Switch detects a network loop. To determine wheth this is the case, connect one network connection at a time, waiting a few seconds between each. 5 PROBLEM SOLVING Unit Connections To connect OfficeConnect units (such as gateways or other switches) to your Switch you need: • One suitable Twisted Pair (TP) cable for each unit 3Com recommends Category 5E cable for Gigabit connections. Workstation Connections To connect workstations or other equipment (such as servers) directly to your Switch, you need: 1 One adapter card for each workstation to be connected to a port on the Switch. The adapter card must be capable of communicating at t required connection speed. For example, if you want to use a Gigabit connection, you must install a 1000BASE-T adapter card. 3Com produce a range of easy to install network adapter cards. 2 An operating system (for example Netware or Windows 95/98/Me/2000/XP) with network support configured, running on yo workstations. 3 One suitable Twisted Pair cable for each workstation. 2 BEFORE YOU INSTALL YOUR SWITC 4 HOW YOUR SWITCH CAN BE USED OfficeConnect Gigabit Switch 5 3C1670500 Port Status On = Link Flash = Activity On = Full 1000M 100M 10M 1 2 3 4 5 Power Alert Duplex 1 2 3 4 5 3 1 2 Figure 3 Workstation connections Safety Information WARNING: Please read the ‘Important Safety Information’ section in the Support and Safety Information sheet before you start.

When positioning your Switch, ensure: • It is out of direct sunlight and away from sources of heat. • Cabling is away from power lines, fluorescent lighting fixtures, and sources of electrical noise such as radios, transmitters and broadband amplifiers. • Water or moisture cannot enter the case of the unit. • Air flow around the unit and through the vents in the side of the case is not restricted. 3Com recommends you provide a minimum of 25 mm (1 in.) clearance. Using the Rubber Feet Use the four self-adhesive rubber feet to prevent your Switch from moving around on your desk, or when stacking with flat top OfficeConnect units. Only stick the feet to the marked areas at each corner on the underside of your Switch. Using a Stacking Clip Use a stacking clip when stacking your Switch with other curved OfficeConnect units. The stacking clip allows you to stack units neatly and securely. CAUTION: You can stack up to a maximum of four units. Smaller units must be stacked above larger units. To fit the clip: 1 Fit the clip across the top of the unit, as shown in Figure 2 (picture 1), ensuring that the longer sections of the fastening pieces are pointing downwards. 2 Align the fastening pieces over the slots found on each side of the unit. 3 Push the clip down gently to secure it, ensuring that the fastening pieces snap into the slots on the unit. To fit another unit: 1 Rest the second unit on the top of the clip and align it with the front of the unit below. 2 Press down gently on the unit to secure it onto the clip, ensuring the fastening pieces fit into the slots on the unit below, as shown in Figure 2 (picture 2). Wall Mounting There are two slots on the underside of the Switch that can be used for wall mounting. The Switch must be mounted with the LEDs facing upwards. When wall mounting the unit, ensure that it is within reach of the power outlet. When wall mounting the unit, ensure that the rubber feet are not fixed. You need two suitable screws. Ensure that the wall you are going to use is smooth, flat, dry and sturdy. Make two screw holes 150 mm (5.9 in.) apart. Fix the screws into the wall, leaving their heads 3 mm (0.12 in.) clear of the wall surface. Remove any connections in the Switch and locate it over the screw heads. When in line, gently push the Switch on to the wall and move it downwards to secure. When making connections, be careful not to push the Switch up and off the wall. CAUTION: Only wall mount single units, do not wall mount stacked units. 1 POSITIONING YOUR SWITCH Figure 2 Stacking Your Units together 1 2 Fastening Piece Fastening Piece
