System Features and Benefits
The Switch 3900 is part of 3Com’s SuperStack family.
To combine diverse technologies as your network
grows, install the Switch 3900 in a SuperStack
network.
Some key features of the SuperStack II Switch 3900
system:
■ High-density Gigabit Ethernet and Fast Ethernet
configurations
The Switch 3900 has 24 or 36 Fast Ethernet ports
and up to three Gigabit Ethernet links.
■ Autonegotiation support
The Switch 3900 supports 10BASE-T/100BASE-TX
and full-duplex and half-duplex autonegotiation
on all front panel ports.
■ Multiple-link trunking for Gigabit Ethernet and
Fast Ethernet links
You can choose the performance level of links
between switches, even scaling beyond one
Gigabit.
■ IGMP Snooping
The Switch 3900 conserves the network
bandwidth that is consumed by audio and video
applications by keeping IP multicast traffic isolated
to specific ports.
■ Trunking links, Spanning Tree, and Advanced
Redundant Power Supply (RPS) support
The Switch 3900 protects against cable and
equipment failures with Spanning Tree Protocol
and trunking links. The optional RPS protects
against power interruptions for fault-tolerant
networks.
■ Manageability
The Switch 3900 provides full support for VLANs,
Fast IP, and RMON Version 1, as well as a roving
analysis port through SNMP management.
System Management
Switch 3900 systems include integrated management
to provide fault tolerance and maximum network
availability. This management is accessible in two
ways:
■ Switch 3900 Administration Console
■ Standard network managers based on SNMP, such
as 3Com’s Transcendware, Sun’s SunNet Manager,
HP OpenView, and IBM’s NetView AIX applications
