ABOUT THIS GUIDE Congratulations on your purchase of your Alloy 24-Port 10/100Mbps Fast Ethernet Smart Switch. This device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package. Purpose This guide discusses how to install your 24-Port 10/100Mbps Fast Ethernet Smart Switch.
INTRODUCTION This chapter describes the features of the 24-Port 10/100Mbps Fast Ethernet Smart Switch and some background information about Ethernet/Fast Ethernet 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 utility include: ¾ Security Security is increased with the reduction of opportunity in eavesdropping on a broadcast network because data will be switched to only those confidential users within the VLAN.
Features ¾ 24×10/100Mbps 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 capability to support rate adaptation and ensure data integrity ¾ Broadcast storm protection ¾ Up to 4K unicast addresses entities per device, selflearning, and table aging ¾ 256KBytes on-chip packet buffer for each e
¾ Standard 19” Rack-mount size UNPACKING AND INSTALLATION This chapter provides unpacking and setup information for the Switch. Unpacking Open the shipping cartons of the Switch and carefully unpacks 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 on each side), and secure them with the provided screws. 24-Por t 10 /100 POWER SYSTE Mb ps Eth ern et Sm art Swi tc h Link/ACT FX M F DX Figure 1.

Mount the 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. These ports are Auto-MDI type port. The Switch can auto transform to MDI-II or MDI-X type, so you can just make an easy connection that without worrying if you are using a standard or crossover cable.
automatically and may be turned on without having any or all LAN segment cables connected. IDENTIFYING EXTERNAL COMPONENTS This chapter describes the front panel, rear panel, and LED indicators of the Switch. Front Panel The figure below shows the front panels of the Switch. Figure 3.
Comprehensive LED indicators display the status of the switch and the network (see the LED Indicators chapter below). ¾ 10/100BASE-T Twisted-Pair Ports These ports support network speeds of either 10Mbps or 100Mbps, and can operate in half- and full- duplex transfer modes.

For example, run the Hyperterminal program packaged with Windows 98/ME/2000/XP, the process will procede as follow: Step 1. Click Start Accessories Communications Hyper Terminal (Figure 6), and then the Connection Description screen will be shown as Figure 7. Figure 6. Start Hyper Terminal function Step 2.
Figure 7. Connection Description 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. Port Settings Configuring the Switch The 24-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 such as Port Configuration and VLAN, shown in the Setup screen.
In the System screen, Factory Reset, Change Password, Confirm Password, Refresh Time, and Login Timeout, can be viewed and changed. System Uptime can’t be altered and governed by the Switch. ¾ File The Switch can be uploaded or downloaded its configuration file by using Upload Configuration or Download Configuration in the File setting screen. ¾ Statistics In the Statistics menu screen, each port’s data transferring and receiving status can be viewed, but can’t be changed.
Figure 10. Login Input the password in the blank, and then press Enter to login Main Menu. If you manage the Switch for the first time, you should input the factory default password “admin” to login to the Switch. To change the password, first highlight System Change Password to input your new password, and then highlight Confirm Password to input your new password again to ascertain it. Main Menu The main menu appears, as shown in Figure 11. Find the console keys in the lower part of the screen.
Figure 11. Main Menu Configuring Setup Setting Note that there are two items, Port Configuration and VLAN in Setup menu, shown as Figure 12.
Figure 12. Setup Menu ¾ Port Configuration In Port Configuration menu (Figure 13), each port’s (port 25: 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.
(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. To change the flow control setting, highlight Port and enter the port number to select the desired port.
Grouping of individual ports into a small “virtual” network of their own being independent of all other ports. To change the VLAN, locate the port that needs to be set, select “V” for joining the VLAN group and “-” for not joining. The default setting of VLAN is shown as Figure 14. Figure 14. VLAN Configuration 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).
VLAN1 1 2 3 4 X 2 3 VLAN2 4 5 Figure 15. There is no connection between PC1 and PC5 Using VLAN, it can divide the Switch into many independent small switches. For example, in Figure 16, the Switch has been divided into four VLAN groups. All VLAN groups are independent and there’s no link between each VLAN group. The Switch can be regarded as four smaller switches. X VLAN1 X VLAN2 VLAN3 Figure 16.
Configuring System Setting The System Configuration Menu screen (shown in Figure 17) indicates the following information: ¾ Factory Reset: Press to turn back to factory setting once the setting in blur. ¾ Change Password: To change the input path password. ¾ Confirm Password: To confirm the new input password. ¾ Refresh Time: To set the refresh time of the device for Statistics. ¾ Login Timeout: Set the console idle time-out to log out the smart menu when forgot to log out.
Configuring File Setting The Switch can have its configuration files uploaded or downloaded by using the File screen shown in Figure 18. ¾ Upload Configuration: Select this for uploading the configuration file to the device. ¾ Download Configuration: Select this for copying or backup the current status. Figure 18.
