-6- 1. Introduction Driven by recent advances in desktop computing technology , t o d a y s network applications have increased in speed, power and the ability to process information.
-7- 1.1 Features Designed for resolving congestion problems caused by bandwidth-hun- gry devices and bandwidth-intensive applications as well as a high num- ber of users, the switches not only adhere to the IEEE 802.3 10BASE-T , IEEE 802.3u 100BASE-TX, and IEEE 802.
-8- Management Features: T elnet for remote control Provides one RS232 local console port 802.1D Bridging - 802.1d spanning tree - 802.1P/Q GARP/GVRP Routing - RIP , RIP-2, DHCP-relay .
-9- 1.2 Specifications Standard IEEE 802.3 10BASE-T , IEEE 802.3u 100BASE-TX IEEE 802.3z 1000BASE-X IEEE 802.3ad Port trunking IEEE 802.3x Full duplex flow control IEEE 802.
-10- 2. Installing the Switch The switch is designed to operate in workgroup environments without a complicated configuration procedure. It also features an auto-select 100- 240V , 50/60Hz power supply unit, which works in most countries around the world.
-11- 2.2 Panels The following figure illustrates the major components on front and rear panels: 10/100 Port 1-12 10BASE-T/100BASE-TX Port #1 - #12 10/100 Port 13-24 10BASE-T/100BASE-TX Port #13 - #24 .
-12- 2.3 Mounting the Switches Desktop Mounting 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 Rack Mounting For mounting the switch into a 19-inch rack, a pair of mounting brackets is included in the pack.
-13- 3. Making Network Connections 3.1 Network Switched Ports The following figure illustrates the switched ports provided on the front panel. The switch comes with 24 10/100BASE-TX Fast Ethernet switched ports and two Gigabit Ethernet slots for Gigabit Ethernet modules.
-14- 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.
-15- 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 • .
-16- 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.
-17- 3.3 Gigabit Ethernet Slots Each Gigabit Ethernet slot can accommodate one optional Gigabit Ether- net module for your Gigabit connection. The following modules are avail- able for selection: Modu.
-18- The Gigabit Ethernet module supports auto-negotiation although it only operates on 1000M full-duplex mode. This function makes sure the system operates with maximum performance when it is connected to an auto-negotiation capable Gigabit Ethernet device.
-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.
-20- Rules : 1. One switch can be configured to have up to 4 trunks and each trunk can be composed of up to 8 trunking ports. All port members of one trunk must locate in same group, either in group [port 1-port 12] or in group [port 13 - port 24]. 2.
-21- 3.5 Virtual LAN (VLAN) Each port of the switch unit connects to one individual LAN segment. There can be many Ethernet nodes located on each segment. The switch performs network data forwarding between different LAN segments. It al- lows Ethernet nodes located on different segments to communicate with each other .
-22- Dynamic Learning of VLAN Membership While port based VLAN only defines static binding between a VLAN and its port members, the MAC address database associated with each port number and VLAN is learned and built up dynamically by the switch at run time.
-23- 4. LED Indicators 4.1 LED Panels The switch provides comprehensive LED indicators for diagnosing and monitoring the operation of the unit as illustrated below: 4.2 Interpretation Power LED : indicates the status of the power supplied to the switch.
-24- 5. Performing Network Management 5.1 Management Support The switch is featured with management functions and can be managed by using the following methods: _ Direct console connection over an RS2.
-25- 5.2 Management objects The following table lists the management objects supported by the system: Login Basic Management Activities _ General Management Configuration - system parameters _ LAN Por.
-26- _ Other Protocols - GVRP , IGMP _ Port Trunking _ Port Mirroring _ File transfer - software upgrade Logout Save settings Restore default settings Reboot 5.
-27- 5.4 Console Management Any PC running Windows 95/98/ or NT can be used as a console. Use the supplied RS232 cable and connect the console port to the COM port of your console PC. Use W indows Hyper T erminal program to perform this out-of-band management operations.
-28- Use the supplied RS232 cable to make the console connection directly from a PC COM port. The pin assignments of the connection are: Switch DTE console port 9-pin PC COM port Pi n 1 DC D ---------.
-29- 5.7 SNMP and RMON Management SNMP management and RMON activities are performed at a network management station running SNMP network management application manager software with graphical user interface.
-30- Note: The TFTP protocol is used to download updated software to the switch. A VLAN with the proper IP address and routing path to the TFTP server must be configured for the switch to access the specified TFTP server . TFTP is an embedded function supported in the DOS window of any W indows NT system.
