1.4 GENERAL DESCRIPTION

Cabletron Systems Ethernet Switch Modules connect the ATX to a
maximum of four individual Ethernet IEEE 802.3 LANs. The Ethernet
Switch Module (3E02-08-ATX) connects to a maximum of eight Ethernet
IEEE 802.3 LANs.
Both module types enable connectivity to FDDI, Token Ring, and
Ethernet networks, and can be configured to support Transparent
Spanning Tree, Source Routing, or Source Routing Transparent Bridging
on each of the ports. The ATX can translate higher level protocols to allow
communication between end-nodes on Ethernet as well as FDDI or Token
Ring. Protocols translated include TCP/IP, Novell NetWare, and
AppleTalk Phase II.
The four port Ethernet Switch Module is available in four versions to
support various cabling types:
• 3E02-04: provides four Unshielded Twisted Pair (UTP) connections
• 3E07-04: provides four thin coaxial cable connections
• 3E08-04: provides four multimode fiber optic connections
• 3E05-04: provides four Attachment Unit Interface (AUI) connections
The 3E02-08-ATX module provides eight UTP connections.
The Ethernet Switch Modules include processing circuitry for receiving
and forwarding data packets between the connected devices. Each module
contains an offline button and several LEDs that indicate the module's and
individual ports' operational status.
The four port modules may be installed in any of the five interface slots
and the ATX can simultaneously support up to five Ethernet Switch
Modules.
The 3E02-08-ATX module may be installed in any of the five interface
slots in a ATX, and the ATX can simultaneously support up to five eight
port modules. Each module provides connectivity to the multiple LANs.
