Description
This installation guide describes Enterasys Networks’ Vertical Horizon
VH-4802 Fast Ethernet switch. The switch provides 48
10Base-T/100Base-TX ports, plus two slots for optional slide-in
100Base-FX, 1000Base-SX or 1000Base-LX modules. There is also a
fixed SNMP-based management card included in the switch. This
management card supports both in-band and out-of-band access for
managing the switch.
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 connect up to 48 end-node workstations or servers using
its 10Base-T/100Base-TX ports. 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 card 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 switch, as well as providing the ability
to configure and control functions in the switch. The management card
also supports Remote Monitoring (RMON) for Statistics, History, Alarm
and Event groups (Groups 1-3, 9).
Network management can be performed in-band using a TCP/IP or Telnet
connection to the switch. This card also includes a built-in Web agent that
provides management access via common http browsers such as
Netscape Navigator and Microsoft’s Internet Explorer. In addition, the
console port allows out-of-band management using a PC, terminal, or
modem connection.
