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.

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
