[. . . ] The 10BASE-T/100BASE-TX/1000BASE-T ports deliver dedicated 10/100/1000 Mbps links to each attached LAN segment. 10/100 Mbps connections support auto-negotiation of speed, flow control, and duplex mode. 1000 Mbps connections support auto-negotiation of speed, duplex mode, and flow control, but only operate at full duplex. This means that you can use either straight-through or crossover cables to connect to any other network device. 1 ABOUT THE EZ SWITCH 10/100/1000 Auto-negotiation is used to select the optimal transmission speed and communication mode for each connection. With store-and-forward switching and flow control, maximum data integrity is always maintained, even under heavy loading. Easy installation and reliability make this plug-and-play switch an ideal choice for delivering high speed Internet access to multiple users.

" Note that this switch can be installed on any suitably large flat surface or in a standard EIA 19-inch rack. Package Contents The EZ Switch 10/100/1000 includes: · EZ Switch 10/100/1000 (SMC8505T or SMC8508T) · Four rubber foot pads · Rack-mount bracket kit · Appropriate DC power adapter · This User Guide · SMC Warranty Registration Card Mounting the Switch This switch can be placed directly on your desktop, or mounted in a rack. Before you start installing the switch, make sure you can provide the right operating environment, including power requirements, sufficient physical space, and proximity to other network devices that are to be connected. Verify the following installation requirements: · Power requirements: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3Hz). The switch's power supply automatically adjusts to the input voltage level. The switch should be located in a cool dry place, with at least 10 cm (4 in) of space on the sides for ventilation. Place the switch out of direct sunlight, and away from heat sources or areas with a high amount of electromagnetic interference. · · 3 INSTALLING THE SWITCH · If you intend to mount the switch in a rack, make sure you have all the necessary mounting screws, brackets, bolts and nuts, and the right tools. Check if network cables and connectors needed for installation are available. · Stacking Switches on a Flat Surface The switch can be placed anywhere there is enough flat space, such as on a table or desktop.

Stick the self-adhesive rubber foot pads (that come with this package) on each of the 4 concave spaces located on the bottom of the first switch. Place the first switch on a firm flat surface where you want to install the stack. The rubber foot pads cushion the switch against shock/vibrations and provide space between each switch for ventilation. Mounting Switches in a Rack Please comply with the following instructions to ensure that your switch is securely mounted in the rack.

Use a cross-head screwdriver to attach the brackets to the side of the switch. 4 CONNECTING THE SWITCH SYSTEM 4. Position the switch in the rack by lining up the holes in the brackets with the appropriate holes on the rack, and then use the rack-mount screws to mount the switch in the rack. Connecting the Switch System The EZ Switch 10/100/1000 provides 5/8 RJ-45 ports on this device. Each of these ports supports connection to 10 Mbps Ethernet, 100 Mbps Fast Ethernet, or 1000 Mbps Gigabit Ethernet. In addition, they are capable of operating at either half or full-duplex at 10 or 100 Mbps. The transmission speed for each port is automatically set by the switch to match the highest speed supported by the connected device. The transmission mode can be set for each port using auto-negotiation (if also supported by the attached device). Making a Connection to an RJ-45 Port Because all RJ-45 ports on these switches support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. [. . . ] Verify that Category 5 cable is used for 100 Mbps connections, Category 5 or 5e cable for 1000 Mbps connections, and that the length of any cable does not exceed 100 meters (328 feet). Replace the defective card or cable if necessary. · · 13 TROUBLESHOOTING Power and Cooling Problems If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the right side of the unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. Installation Verify that all system components have been properly installed. [. . . ]
