INTRODUCTION This chapter describes the features of the 16-Port 10/100Mbps Fast Ethernet Smart Switch and some background information about Ethernet/Fast Ethernet and Switching technology. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times.
Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network.
VLAN (Virtual Local Area Network) A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if in a common broadcast domain, a LAN. The primary utility of using VLAN is to reduce latency and need for routers, using faster switching instead. Other VLAN features include: ¾ Security Security is increased with the reduction of opportunity for eavesdropping on a broadcast network because data will be switched only to those users within the particular VLAN.
Features ¾ 16×10/100Mbps Auto-negotiation Ethernet ports ¾ All ports support auto MDI/MDIX, so there is no need to use cross-over cables or an up-link port ¾ Full/half duplex transfer mode for each port ¾ Wire speed reception and transmission ¾ Store-and-Forward switching scheme with capability to support rate adaptation and ensure data integrity ¾ Broadcast storm protection ¾ Up to 4K unicast address entities per device, selflearning, and table aging ¾ 256KBytes on-chip packet buffer for eac
UNPACKING AND INSTALLATION This chapter provides unpacking and setup information for the Switch. Unpacking Open the shipping carton of the Switch and carefully unpack its contents.
Installation The site where you install the hub stack may greatly affect its performance. When installing, consider the following pointers: ¾ Install the Switch in a fairly cool and dry place. See Technical Specifications for the acceptable temperature and humidity operating ranges. ¾ Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.
Rack Mounting The switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the switch’s front panel (one each side), and secure them with the screws provided. 16-Po POWE R SYST EM rt 10/1 0 0M b ps Eth ern et Sm art Swi tc h Link/ACT FX F DX Figure 1. Combine the Switch with the provided screws Then, use screws provided with the equipment rack to mount each switch in the rack.
Connecting Network Cable The Switch supports 10Mbps Ethernet or 100Mbps Fast Ethernet and it runs both in half and full duplex modes. The Switch ports are Auto-MDI types. The Switch can automatically change all ports between MDI-II & MDI-X types alleviating any worry about using standard or crossover type cables. AC Power The Switch can be used with an AC power supply of 100~240V AC, 50~60 Hz.

CONFIGURATION This Switch is an unmanaged, but “smart” Switch because programmable administration parameters make it operate more effectively than regular unmanaged (dumb) switches. This chapter describes how to configure the Switch. Console Port (RS-232 DCE) The console configuration requires connecting a terminal, such as a Workstation or a PC running a terminal emulation program (such as HyperTerminal, which is automatically installed with Microsoft Windows) to the RS-232 DCE console port of the Switch.
Figure 6. Start Hyper Terminal function Step 2. Enter a name in the blank to set up a new connection, and then press OK. Figure 7.
Step 3. The Connect To screen will appear as below. Pull down the Connect using and choose the COM port that the Switch has been connected to, then press OK. Figure 8. Connect To Step 4. Make sure the Switch serial port parameters have been set as per the factory default settings (Figure 9). Click OK to configure the Switch. Figure 9.
Configuring the Switch The 16-Port 10/100Mbps Fast Ethernet Smart Switch has a menu-driven console interface for smart switch configuration. The Switch can be configured through the serial port. A network administrator can manage, control and monitor the switch from the console program. This section indicates how to configure the Switch to enable its smart functions including: ¾ Setup There are two items, Port Configuration and VLAN, shown in the Setup screen.
Login First execute the terminal emulation program on the remote workstation, and turn on the Switch. When logging into the Switch, the following screen (Figure 10) prompt appears: Password: Figure 10. Login Insert the password into the blank space and then press Enter to log in to the Main Menu. If you are managing the Switch for the first time, you should input the factory default password “admin” to log in to the Switch.
Main Menu The main menu appears, as shown in Figure 11. Note the console keys in the lower part of the display. Move to highlight a desired option by using Up Arrow, Down Arrow and Tab keys, and then press the Enter key to confirm. There are four options: Setup, System, File, and Statistics, shown in the Main Menu screen. Figure 11.
Configuring Setup Menu Note that there are two items, Port Configuration and VLAN, in Setup menu as shown in Figure 12. Figure 12. Setup Menu ¾ Port Configuration In the Port Configuration menu (Figure 13), each port’s (inc. port 17: Fibre port) Speed, Flow Control, and QoS can be controlled. Link Status is automatically determined by the Switch and can’t be shifted.
Figure 13. Port Configuration (1) Speed There are five modes— Auto, 100M Full, 100M Half, 10M Full, and 10M Half—for speed selections. To change the speed setting, highlight Port and enter the port number to select the desired port, next highlight Speed, click Enter, and use Space Bar to switch between the five different options. (2) Flow Control This setting determines whether or not the Switch will be handling flow control.
High and Low. The default setting for QoS on all ports is High. To change the QoS setting, highlight Port and enter the port number to select the desired port. Set QoS as required to determine which ports will always transfer their data first. (4) Link Status This value is automatically determined by the Switch and can’t be changed. If there is a valid connection to the Switch through the indicated port, the Link Status will show the connection speed.
For example, there are five computers (PC1~PC5) connected to the Switch’s port 1~5. They had been divided into two VLAN groups: VLAN1 (PC1~PC4) and VLAN2 (PC2~PC5). There is no way to connect PC1 and PC5, as shown in Figure 15. If PC1 has to connect to PC5, it should with it in the same VLAN. VLAN1 2 1 3 4 X 2 3 VLAN2 4 5 Figure 15. There is no connection between PC1 and PC5 Using VLAN, the Switch can be divided into many independent small switches.
Configuring System Setting The System Configuration Menu screen (shown in Figure 17) indicates the following information: ¾ Factory Reset: Press to revert to factory settings if the configuration becomes corrupt. ¾ Change Password: Change the input password. ¾ Confirm Password: Confirm the new input password. ¾ Refresh Time: Set the refresh time of the device for Statistics. ¾ Login Timeout: Set the console idle time-out to log out the smart menu if it has been forgotten to do this.
