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.
