7 Chapter 1 Introduction Fast Ethernet T echnology The growing importa nce of LANs and the increasing comple xity of desktop computi ng applications are fueling t he needs for high performance networks. A num ber of high-speed LAN technologies are availabl e to provide greater bandwidth and improve clie nt/server response tim es.
8 Ethernet Fast Ethernet Speed 10Mbps 100Mbps Cost x 2x or less IEEE 802.3 Standard CSMA/CD CSMA/CD Topology Star or Bus Star Cable Supported UTP, Coax, Fiber UTP, Fiber Cable Specification 10Base-T:C.
9 performance or “wire-speed.” Th erefore, a switch effectively splits a physical shared-access L AN into bridged multiple LAN segments. Each segm ent supports a workgroup and even provides a dedicated connection to a desktop server.
10 can no longer provide both bandwidth and predic table response times t o this new generation of workgroup com puting. From an econom ical point of view, Fast Et hernet switching not only satisfies bot h technical and business requirem ents, but also preserves the users’ existing investm ent in the huge 10Base-T Ethernet installed base.
11 doubles network throughput to 200Mbps on Fast Ethernet segments and 20Mbps on 10B ase-T segments. Although the TE100-S55 is equipped wi th five ports for 10Base- T or 100Base-TX connections, it also provi des an open slot for add-on modules. These m odules include an 8-port 10Base-T, a 100Base-FX/TX port or an ISDN router.
12 Featur es of TE100-S55 Utilizing the latest Fast Ethern et and Switching technologies, the TRENDnet TE100-S55 is designed to provide: • Five 10/100Mbps dual-speed Ethernet ports • One expans io.
13 Chapter 2 Getting S t arted Cabling Rules and Site Pr eparation Although 100Base-T and 10Base-T are alike in m any aspects, there are slight differences in th e cabling rules. So, spend some time i n locating and reconfiguring your cabli ng structure for the best network layout.
14 The TE100-S55 fits into the 100Base-T cabling archi tecture as a switch. Therefore, unlim ited num ber of switches m ay be installed in the same network wi th maxim um dist ances of 100 meters apart . The 10/100Mb ports of TE100-S55 require two-pai r Cat5 UTP (or Type 1 STP) for 100Base-TX connections.
15 Careful planning and site preparation are the keys to success for installing Fast Ethernet switches. Users should perform a network bandwidth analysi s based on their workgroup network traffic needs and examine their workstati on equipment for other performance bottlenecks.
16 Unpacking and Setup Now that you have a good understanding of t he basic cabling rules, as well as your own network envi ronment, you’re ready to integrate the TE100-S55 into the network. The following sections describe how t o install, connect and setup your new TE100-S55 .
17 THE F RONT P ANEL The TE100-S55 features following ite ms on its front panel: (A) Five RJ-45 ports for 10Base-T or 100Base-TX l inks (B) An expansion slot with multiple configuration options: (b1) .
18 M OUNTING The TE100-S55 can be placed either on a table or rack mounted. For rack mounting: Fi rst screw the pair of mount ing brackets (included in the packing carton) ont o the switch. Then, m ount the TE100-S55 onto the rack, as shown below in Figure 2-5 .
19 If you are connecting workstations t o the TE100-S55, use a standard UTP cable with a straight RJ-45 pin layout . If you are connecting hubs, bridges or other switc hes to the TE100-S55, the Transmit (TD) and the Receive (R D) wires m ust be crossed-over at one end of the connector.
20 S OFTWARE S ETUP The default settings of TE100-S55 ( shown i n Appendix A, page 45 ) should be sufficient in the m ajority of i nstallations. If a different setting is required for your specific environm ent, please refer to Chapter 3, page 21 for “Out-of-Band Ma nagement” or Chapter 4, page 35 for “SNMP Managem ent”.
21 Chapter 3 Configuring the Switch Intr oduction The TE100-S55 is designed to operate wit h or without the aid of extensive network ma nagement software. For si mple managem ent, you can run a term inal em ulation program and access the TE100-S55 through its RS-232 port.
22 Out-of-Band Management A TTACHING TO THE RS-232 P ORT The TE100-S55 can be configured using the Out-of-Band Management function. To begin, you m ust first connect a PC (or a terminal ) directly to TE100-S55 usi ng the supplied RS-232 serial cable. The RS-232 port is a DCE wit h a 9-pin female connect or.
23 VT100 T ERMINAL Once you’ve connected a PC (or term inal) to the RS-232 port of the TE100-S55, you can begin the VT100 term inal em ulation process. The VT100 terminal emulation soft ware can be found in Microsoft Windows or any other com municat ion software.
24 Upon a successful execution of terminal em ulation, your computer will establish comm unication with the TE100-S55 and allow you to view or m odify the foll owing settings. Control Settings System display User selection Switch Configuration Switch Version No.
25 U SER -S ELECTIVE P ARAMETERS The TE100-S55 is factory set with a uni que Ethernet MAC address. Except for the MAC address, Version Number and Port State, all parameters in Table 3-2 can be modi fied. From the Swit ch Configurat ion menu , you can change the IP Address of TE100-S55 to matc h the TCP/IP environm ent of your network.
26 From the Down-load Ne w System Firmware menu , you can upgrade the TE100-S55 with the latest firmware (if revi sion is available). The XMODEM function will g uide you in downloading the firm ware code into the TE100-S55. To acquire the revised firmware file, pleas e contact TRENDware technical support.
27 Spanning T r ee Algorithm In a more compl ex network environment , devices may physically be connected in a loop, causing network failure due t o the infinite transfer of packets. In anticipatio n of such perplexity, th e TE100-S55 is designed to support the Spanning Tree Al gorithm (STA).
28 You can view or modify the STA paramete rs through the Out-of- Band Managem ent, as shown in Table 3-3 . Pay special attention to the effects of each STA parame ter in order to avoid erroneous behavior in the network.
29 STA operates at two levels, the Switch and the Port level. In addition, STA uses several timers to period ically ensure the integrity of swi tches/bridges and their ports in a network. The following paragraphs introduce the key i nformation and terminol ogy needed to understand the STA param eters.
30 A T THE P ORT LEVEL Designated Port: This is the port on each Designated Bridge that forwards data packets for the attached LAN segment. Root Port: Each bridge has a Root Port that has the lowest Pat h Cost to the Root Bridge.
31 T IMERS Max. Age Time: This is a user changeable parameter. Shoul d a Bridge fail to receive an identif ier packet from its Root Bridge within this time limit, it assumes that the Root Bridge has failed. Therefore, a new Root Bridge will be estab lished for the network.
32 I LLUSTRATION OF STA A simple illustration of three Br idges (or TE100-S55) connected in a loop is depicted in Figure 3-2 . In this exam ple, you can anticipate som e major net work pr oblems if the STA assistance is not applied.
