DUA1646-0AAA02 1 SAFETY INFORMATION Please read the following safety information carefully before installing the Baseline Switch. WARNING: Installation and removal of the unit must be carried out by qualified personnel only. [. . . ] Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets. The equipment that is connected to the Baseline Switch must not be set up to operate in full duplex. Set it up to operate as auto-negotiate or half duplex. 3 WARNING: RJ45 ports. They cannot be used as telephone sockets. Only connect RJ45 data connectors to these sockets. Ceux-ci sont les prises de courant de données RJ45 protégées. Ils ne peuvent pas être utilisés comme prises de courant téléphoniques. Brancher seulement les connecteurs RJ45 de données à ces prises de courant. Hierbei handelt es sich um abgeschmirte RJ45 Datenbuchsen, die nicht als Telefonbuchsen verwendbar sind. Nur RJ45 Datensteckverbinder an diese Buchsen anschließen. If the unit is to be part of a free standing stack, apply the pads to each marked corner area on the underside of the unit. Place the unit on top of the lower unit, ensuring that the pads of the upper unit locate with the recesses of the lower unit. Positioning the Baseline Switch 3 3 3 3 CAUTION: When installing the Baseline Switch in a stack of different size units, the Baseline Switch must be installed above the larger units. When deciding where to position the Baseline Switch ensure: It is accessible and cables can be connected easily. Cabling is away from: 10 MDI Switch (for port 14) Ports 13 is fixed as an MDIX port so that it can be connected directly to DTE which have MDI ports using normal `straight through' TP cables. Port 14 is `switch selectable' using the MDI Switch. The port can be an MDIX port (to connect directly to DTE like port 13), or an MDI port (to connect to other units using a normal `straight through' TP cable). Out MDIX 3 sources of electrical noise such as radios, transmitters and broadband amplifiers. 3 power lines and fluorescent lighting fixtures. 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 recommend that you provide a minimum of 25mm (1in. ) clearance). In this position you can connect port 14 to a workstation or any other DTE using a normal `straight through' TP cable. In this position you can connect port 14 to any MDIX port on a 10BASE-T or 100BASE-TX unit using a normal `straight through' TP cable. In MDI To prolong the operational life of your units: 3 Never stack units more than six high if free standing, and ensure that cables are supported so that they do not cause the stack to fall over. To connect a 10BASE-T or 100BASE-TX unit to the Baseline Switch, connect an MDIX port on the other unit to port 14 on the Baseline Switch, as shown below. Ensure that the MDI switch on the Baseline Switch is IN (MDI). If an MDI/MDIX port is used on the other unit, ensure that the MDI switch for that port is OUT (MDIX). 3 3 Do not place objects on top of any unit or stack. Do not obstruct any vents at the sides of the case. Rack or Wall Mounting The Baseline Switch can be mounted in a 19-inch equipment rack, or wall-mounted using the Mounting Kit. Refer to "Mounting Kit Instructions". Power Up Use the following sequence to power up the Baseline Switch: 3 Check the network connections and cables. 3 3 Connect the power supply cable to the appropriate power socket on the rear panel of the unit. Connect the plug to the power supply outlet socket and switch on the power supply at the socket. [. . . ] Contact your supplier for the latest product information and to order these products.
