3E02-04 Ethernet Switch Module - Cabletron Systems 3E02-04 User Manual

Each module provides connectivity to the multiple LANs. Since packets
are bridged/routed across Ethernet Switch Modules only when it is
necessary to reach the end device, each four port module can support four
distinct 10 Mbps LANs, while the eight port module supports eight
distinct 10 Mbps LANs.

1.5 3E02-04 ETHERNET SWITCH MODULE

The 3E02-04 (Figure 1-2) provides connection for four independent
10BASE-T LANs to the ATX backplane and packet processing module. It
includes processing circuitry for receiving and forwarding packets
between the connected 10BASE-T LANs. The module provides several
LEDs to indicate the module's operational status.
The module supports twisted pair Ethernet and the IEEE 802.3
10BASE-T specification.
