2. Installing the Switch The switch is designed to operate in workgroup environments without a complicated configuration procedure. It also features an auto-select 100240V, 50/60Hz power supply unit, which works in most countries around the world. Before connecting the supplied power cord into the switch, check to see that the cord voltage and current rating conform to the standards of the country of operation. 2.

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.
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.
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. MDI-X and MDI RJ-45 Connectors MDI-X jack is labeled [X] normally to indicate the jack is designed with internal crossover function. It allows a connection to an end station using straight-through UTP cable.
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 10/100BASE-TX dual speed hub ports 10/100BASE-TX switch ports Auto-negotiation Capable The ports support auto-negotiation function when establishing a link connection with any auto-negotiation capable device. The connection speed and duplex mode are determined through the negotiation process with the connected device.
Flow Control Half-duplex mode uses back pressure flow control to prevent the receiving 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. UTP Cable Connections When making a connection to another device using straight-through UTP cable, make sure MDI-X to MDI connection rule is followed.
3.3 Gigabit Ethernet Slots Each Gigabit Ethernet slot can accommodate one optional Gigabit Ethernet module for your Gigabit connection. The following modules are available for selection: Module 2240-SX 2240-SXJM Wavelength Connector type Fiber cable 850nm SC Multimode fiber 850nm MT-RJ Multimode fiber Module 2240-SX 2240-SX 2240-SXJM 2240-SXJM Fiber cable used 50/125µm 62.5/125µm 50/125µm 62.
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. Duplex Mode Full duplex Fiber cable MM 50/125mm, 62.5/125mm recommended Module Installation 1. Turn off the power to the switch unit. 2. Open the cover of Gigabit slot. 3. Insert the module into slot until it is seated properly. 4.
3.4 Making Trunk Connections Two 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. To increase the bandwidth for the connection between two switch units, a trunking function is implemented on the switch unit for this purpose. Normal data ports can be configured optionally as trunking ports through the network management operation.
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. One trunking port can only belong to one trunk. 3. Only one trunk can exist between two switch units. 4. Crossover UTP cables should be used at the same time for one trunk connection. The length of each cable can be up to 100 meters. 5.
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 allows Ethernet nodes located on different segments to communicate with each other. Basically, all Ethernet nodes are in one single LAN. A Virtual LAN (VALN) is a logical, independent workgroup within a network.
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. Dynamic Learning of Remote VLAN In addition to adding and deleting VLAN member ports through network management console software statically, the switch also supports GVRP (GARP VLAN Registration Protocol).
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. Link/Act. LED : indicates the port cable link and traffic activity. Speed LED : indicates the connection speed used Duplex/Col.

The information includes the network address, subnet mask, broadcast IP, IP of the default router.
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 Windows Hyper Terminal program to perform this out-of-band management operations. Factory default settings of the Console port Baud rate : 115200, N, 8, 1, 1 Flow control : disabled Modem control : disabled The console interface consists of a series of menu boxes. Each menu box has several options, which are listed vertically.
Use the supplied RS232 cable to make the console connection directly from a PC COM port.
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. The switch serves as an SNMP agent and provides RMON capabilities that allows network administrators to set parameters and view statistical counters defined in the MIB-II, Bridge MIB, private MIB and RMON MIB. The supported MIBs are available in the supplied CD-ROM of the switch.
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 Windows NT system. Contact your dealer for any new available software version. 5.9 Support This guide covers the basic information about the management functions supported by the managed switch.
