Description
This installation guide describes Enterasys Networks’ Vertical Horizon
VH-2402S Fast Ethernet switch. The switch provides 24
10Base-T/100Base-TX ports, plus two slots for optional slide-in
100Base-FX, 1000Base-SX or 1000Base-LX 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 5 Gbps high-speed backplane. There is also an
optional SNMP-based Management Module that can be installed in the
rear panel. This module supports both in-band and out-of-band access for
managing the switch and the attached stack.
The switch employs a high-speed switching fabric. This design allows for
simultaneous transport of multiple packets at low latency on all ports. It
also uses store-and-forward switching to ensure maximum data integrity.
In this mode, the entire packet must be received into a port buffer and
checked for validity before being forwarded. This prevents errors from
being propagated throughout the network. This switch also features full-
duplex capability on all ports, which effectively doubles the bandwidth of
each connection.
The switch can be used in a standalone configuration, or can be stacked
up to seven high to form a single logical switch with up to 182 ports. When
stacked, the 5 Gbps stack backplane provides enough bandwidth for the
most demanding environment. Moreover, you can use a 100 Mbps fiber
module for connecting to a remote site, or a Gigabit module for a high-
speed backbone connection.
The RMON/SNMP/Web Management Module provides a broad range of
management options. It includes a standards-compliant Simple Network
Management Protocol (SNMP) agent. The SNMP agent allows network
management station applications to collect and present status and
performance information about the stack, as well as providing the ability
A switch stack, or a switch in a standalone configuration, must
have an optional Management Module installed to enable all
ports. The base unit alone has all ports disabled by default.
