ELS100-48tx2m.book Page 7 Thursday, November 16, 2000 4:59 PM Feature Summaries The following summaries describe VH-4802 features in areas such as standards compliance, functionality, performance, and options. IEEE 802.1D Bridge The VH-4802 switch is fully compliant with IEEE 802.1D transparent bridging specifications. An address table is provided for learning, filtering, and forwarding. The switch can support up to a maximum of 12K addresses.
ELS100-48tx2m.book Page 8 Thursday, November 16, 2000 4:59 PM Software Download The VH-4802 switch supports the industry-standard Trivial File Transfer Protocol (TFTP) for downloading software to the switch. All switch software is stored in a 2 MB sectored flash ROM. The download feature allows you to easily install software upgrades to the unit. Software can alternatively be downloaded via the serial console port using the XMODEM protocol.
ELS100-48tx2m.book Page 9 Thursday, November 16, 2000 4:59 PM • SNMP-based network manager, in-band The system can also be managed using SNMP, the most common protocol used today for network management. Standard agent MIBs embedded in the switch provide basic SNMP management through industry-standard SNMP applications. Management security protection is provided based on SNMP community names. See Chapter 4, “SNMP Management,” in the Management Guide for more information.
ELS100-48tx2m.book Page 10 Thursday, November 16, 2000 4:59 PM Auto-negotiation Auto-negotiation is a process that permits the switch to automatically select the operational modes of its 10/100 RJ-45 ports. Upon first being connected, the switch detects the speed of the network the port is connected to, either 10Mbps or 100Mbps, and the type of communication setting, half or full duplex. The port is then automatically set by the switch to operate in the proper mode, without user intervention.
ELS100-48tx2m.book Page 11 Thursday, November 16, 2000 4:59 PM Flow Control Flow control allows you to manage network traffic during congestion periods and to prevent the loss of packets when port buffer thresholds are exceeded. Flow control also serves to deny access to additional traffic that could add to a congestion condition. The VH-4802 switch supports flow control per the IEEE 802.3x standard.
ELS100-48tx2m.book Page 12 Thursday, November 16, 2000 4:59 PM Factory Defaults Table 1-4 lists the default settings for switch configuration parameters. Each parameter can be changed via the console menus or Telnet. Table 1-4.

ELS100-48tx2m.book Page 14 Thursday, November 16, 2000 4:59 PM Application Examples The exploding popularity of the Internet and of corporate intranets, as well as new, high-bandwidth desktop applications, are driving the demand for Fast Ethernet. The increase in multimedia traffic and the need to support legacy protocols alongside new, data intensive applications is driving the need for network segmentation and traffic prioritization.
ELS100-48tx2m.book Page 15 Thursday, November 16, 2000 4:59 PM Client/Server Network Application To improve workstation performance in a client/server environment, the VH-4802 switch can be configured to provide 200 Mbps full duplex Fast Ethernet connections to servers by connecting each to a dedicated switch port (Figure 1-4). Users can be accommodated through connections to hubs, both at 10Mbps and 100Mbps speeds, through 10Mbps switches with 100Mbps uplinks, or through direct connections.
ELS100-48tx2m.book Page 16 Thursday, November 16, 2000 4:59 PM Local Backbone Application The VH-4802 switch can be used in a local backbone application, connecting network segments together and providing file-server access (Figure 1-5). Workgroup hubs are provided with a single connection to the switch while servers are put on dedicated 100 Mbps ports. Routers and other networking devices can connect off of the switched backbone as well.

ELS100-48tx2m.book Page 18 Thursday, November 16, 2000 4:59 PM • Environmental Install the VH-4802 switch in a dry area, with adequate air circulation. Avoid placing the switch in direct sunlight or near other heat sources, such as hot-air vents. For temperature and humidity specifications, see Appendix A, “Technical Specifications.” • Ventilation Do not restrict airflow by covering or obstructing air inlets on the side of the switch.
ELS100-48tx2m.book Page 19 Thursday, November 16, 2000 4:59 PM Mounting the Switch in a Rack The switch ships with two (2) multi-position mounting ears and four (4) mounting screws. The mounting screws are used to attach the mounting ears to the switch. Once the ears are attached to the switch, you will need to provide appropriate screws to mount the switch in a rack. Figure 2-1 shows the orientation of the mounting ears for attaching the ears to the switch for a rack mount application.
ELS100-48tx2m.book Page 20 Thursday, November 16, 2000 4:59 PM Installing an Optional Module into the Switch Optional modules are available for media expansion. These modules can be installed into either of the two modular slots on the rear panel of the switch. DO NOT install slide-in modules with the switch powered on. Be sure you power off the switch before installing any module. To install an optional module into the switch, do the following: 1. Disconnect power to the switch. 2.
ELS100-48tx2m.book Page 21 Thursday, November 16, 2000 4:59 PM Connecting a Terminal to the Console Port The console port is a serial RS-232 interface port that enables a connection to a terminal for performing switch monitoring and configuration functions. The terminal may be a PC or workstation running terminal emulation software, or a terminal configured as a Data Terminal Equipment (DTE) connection. Alternatively, this port can be connected to an external modem to enable remote dial-in management.
