8 Product Overview

VH-4802

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.

A TFTP software download is invoked via the Management Setup Menu

using the console menus. A TFTP download can also be invoked using

the on-board Web agent or via SNMP.

Non-Volatile Parameter Storage

Important operating parameters such as IP addresses, Spanning Tree

configuration, and management security parameters, are stored in non-

volatile flash memory. These values are retained when the switch

experiences power interruptions or is powered down for normal

maintenance.

Configuration and Management Interfaces

The VH-4802 switch can be managed using any of the following methods:

Serial console, out-of-band

An RS-232 connection, using a DB-9 connector, is included on the

rear panel for system management. Serial console management can

be performed out-of-band using a terminal or computer running

communications software. You can connect directly to the RS-232

port on the rear panel, or make a connection via a modem. See the

Management Guide for information on managing the VH-4802 switch

via the serial console.

Telnet, in-band (over Ethernet)

The switch supports management through a Telnet connection using

the TCP/IP protocols. Telnet is performed using a terminal or

computer running communications software. See the Management

Guide for information on managing the system via Telnet. Global

user name and password protection for changing the operating

parameters of the switch is provided.

Web-based network manager, in-band

The system can be managed over HTTP protocol with a Web

browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0

or above). Standard agent MIBs embedded in the switch provide

basic SNMP management through an embedded graphic interface.
