ABOUT THE EZ SWITCH 10/100 The EZ Switch™ 10/100 SMC-EZ1024DT is a 24-port Fast Ethernet switch. The 10BASE-T/100BASE-TX ports deliver dedicated 10/100 Mbps links to each attached LAN segment – all with conventional cabling and adapters. Auto-negotiation is used to select the optimal communication mode for each connection. Auto-sensing is used to select the optimal transmission speed for each connection.
ABOUT THE EZ SWITCH 10/100 ◆ Plug-and-play ◆ “At-a-glance” LEDs for port and system status monitoring ◆ Desktop and rack mountable Front Panel LEDs The front panel of the switch provides a link status LED for each RJ-45 port. In addition, the front panel also contains status LEDs for “at-a-glance” system monitoring.
REAR PANEL Port and Switch Status LEDs LED Condition Status FDX On The port is in full-duplex mode. Off The port is in half-duplex mode. Flashing Packet collision is occurring in half-duplex mode. Rear Panel The AC power socket is located on the rear panel of the switch.
INSTALLING THE SWITCH The EZ Switch 10/100 can be placed on a desktop or shelf, or installed in a standard 19-inch equipment rack. Equipment Checklist After unpacking the EZ Switch 10/100, check the contents of the box to be sure you have received the following components: • EZ Switch 10/100 SMC-EZ1024DT • Appropriate AC power cable • Rackmount kit • SMC Warranty Registration Card • This User Guide Immediately inform your dealer in the event of any incorrect, missing or damaged parts.
SELECTING A SITE Selecting a Site Be sure to follow the site selection guidelines below when choosing a location: Select a suitable location for the switch: • It should be accessible for installing, cabling and maintaining the switch. • The temperature and humidity should be within the ranges listed in the specifications. • The status LEDs should be clearly visible. • There should be adequate space (approximately two inches) on all sides for proper air flow.
INSTALLING THE SWITCH Make sure that a properly grounded power outlet is within 2.44 meters (8 feet) of the switch and is powered from an independent circuit breaker. As with any equipment, using a filter or surge suppressor is recommended. Instructions 1. Positioning the Switch: For desktop or shelf mounting, attach the four adhesive feet to the bottom of the switch. For rack-mounting, attach the mounting brackets on both sides of the switch with the screws provided, and install the switch in the rack.
SAMPLE APPLICATIONS Some typical applications for the EZ Switch 10/100 are illustrated below: Standalone LAN In the figure below, the EZ Switch 10/100 is operating as a collapsed backbone for a small LAN. It is providing dedicated 10 Mbps full-duplex connections to workstations and 200 Mbps full-duplex connections to power users and servers.
SAMPLE APPLICATIONS High-Speed Switch Links In this application a 200 Mbps full-duplex link is made to a second EZ 10/100 switch.
TROUBLESHOOTING 1. Symptom Power LED does not light after power on. Probable Causes Power outlet or power cord may be defective. Possible Solutions • Check for loose connections. • Check the power outlet by using it for another device. • Replace the power cord. 2. Symptom Link LED does not light after connection is made. Probable Causes Switch port, network card or cable may be defective. Possible Solutions • Check that the switch and attached device are both powered on.

Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires.
TWISTED-PAIR CABLE AND PIN ASSIGNMENTS The figure below illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins. 10BASE-T/100BASE-TX Pin Assignments With standard straight-through 10BASE-T/100BASE-TX cable, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for receiving data. The “+” and “-” signs in the table below are used to represent the polarity of the wires that make up each wire pair.
