8 Product Overview VH-2402S
Software Download
The VH-2402S 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-2402SVH-2402S switch, or attached stack, 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
Management Module 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 Management Module, or make a
connection via a modem. See the Management Guide for information
on managing the VH-2402S switch (or stack) 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.
