INTRODUCTION:
The VH-2402S is a 24 port dual-speed manageable standalone, stackable or rack-mountable switch. The switch
provides 24 10Base-T/100Base-TX ports, plus two rear-panel slots for optional slide-in 100Base-FX, 1000Base-
SX ,1000Base-LX or 1000Base T modules. One of these slots can also be used for an optional stacking module
that allows you to attach up to seven switches to a 4 Gbps high-speed backplane. There is also another rear-
panel slot that accepts an optional SNMP-based Management Module. This module supports both in-band and
out-of-band access for managing the switch and the attached stack.
The VH-2402Sswitches can be used in a standalone configuration, or can be stacked up to seven high to form a
single logical switch with up to 168, 10/100 Mbps ports. One optional Management Module is required for
configuring a standalone switch or an entire stack. The optional stacking Interconnect Module and Interconnect
Cables are not included with the base unit and need to be ordered separately.
Management of the switch or stack is provided when an optional Management Module is installed. Management
access is provided in-band via Telnet, SNMP, or out of band via the serial console port interface either directly or
through an attached modem. An imbedded Web agent also provides management capability to any computer on
the network via common Http browsers such as Netscape Navigator or Microsoft’s Internet Explorer (Note: Both
browsers should be Version 4.0 or above.)
Local Console Management (LCM) allows the user to monitor and configure the VH-2402S from a VT-type
terminal. LCM can be used to configure features such as SNMP community names and access rights, Port
Enable/Disable, firmware downloads, and Device IP address as well as most other parameters. LCM can also
provide statistical and diagnostic information about the entire device or an individual port.
Management of the switch or stack is password protected; the same password is used for LCM and for the Web
browser interface. Prior to accessing the Management Module via a network connection, a valid IP address,
subnet mask, and in some cases a default gateway must be configured using an out of band connection or the
BootP protocol. The management option provides SNMP, RMON (4 groups: 1,2,3,9), and Web management for
system control and statistical monitoring.
It is recommended that one thoroughly review this release note prior to the installation or upgrade of
this product.
