-11- 2.3 Mounting the Switches The switches can be placed on a desktop as a stand-alone unit. Allow enough ventilation space between the switch and the objects around it. Desktop Mounting For mounting the switch into a 19-inch rack, a pair of mounting brackets is included in the pack.
-12- 3. Making Network Connections 3.1 Network Switched Ports The following figure illustrates the switched ports provided on the switch. The switch comes with nine Fast Ethernet switched ports and Port #9 provides two connection types, one is 10/100BASE-TX RJ-45 connector and the other is 100BASE-FX fiber slot.
-13- • 10/100BASE-TX Fast Ethernet Switched Ports Each switched port supports one connection to a LAN segments. Each segment is an independent shared network in one collision-domain. The connection can be to either a 10BASE-T or a 100BASE-TX device.
-14- 3.2 10/100BASE-TX Fast Ethernet Ports The switch can support connections to the following devices: • 10BASE-T or 10/100BASE-TX network cards • 10BASE-T hub ports • 100BASE-TX hub ports • .
-15- Flow Control Half-duplex mode uses back pressure flow control to prevent the receiv- ing buffer from being overrun by data from a source node. Full-duplex mode uses the 802.3x flow control standard to prevent fast Physical Ports data traffic from overrunning slow data traffic.
-16- 3.3 Fast Ethernet Fiber Slot The switch provides one fast Ethernet fiber slot. It can accommodate one optional fiber module for your fiber connection.
-17- Module Outline The following figure illustrates an example of the fiber modules. Different type of modules is mounted with different fiber connector . Fiber Module (T op view) Fiber Jumper Setting The jumper group J1 on the module is used to enable or disable the fiber module.
-18- Duplex Mode Setting The duplex mode used for the fiber module is configured by software port control settings. See chapter 5 for more information. Specifications Standard IEEE 802.3u 100BASE-FX Speed 100Mbps Duplex mode Full duplex or half duplex Wavelength 1300nm Fiber Connectors ST , SC, MT-RJ, VF-45 Fiber cable MM 50/125 m m, 62.
-19- 3.4 Making T runk Connections T wo switch units can be cascaded together through any regular switched data port on each unit when a port expansion is required. However , the transfer bandwidth between the two cascaded ports is limited to 200Mbps full duplex.
