Cabletron Systems 3H08-04 用户手册

 

Cabletron Systems Fast Ethernet Switch Modules connect the ATX hub 
to a maximum of four individual Ethernet IEEE 802.3 Local Area 
Networks (LANs). Through the ATX backplane, connectivity to other 
Fast Ethernet devices, as well as connectivity to FDDI, Token Ring, and 
Ethernet networks is supported. You can configure the module to support 
Transparent Spanning Tree, Source Routing, or Source Routing 
Transparent Bridging on each of the FDDI, Token Ring, or Ethernet ports 
of the ATX. The ATX is also able to translate higher level protocols to 
allow communications between end-nodes on Ethernet and end-nodes on 
FDDI or Token Ring; protocols translated include TCP/IP, Novel 
NetWare, and AppleTalk Phase II.

The switch modules include processing circuitry for receiving and 
forwarding data packets between the connected devices. Each module 
contains an offline button as well as several light emitting diodes (LEDs) 
that indicate the operational status of the module and the individual ports.

You can install the switch modules in any of the five interface slots of the 
ATX. Each switch module provides connectivity to four distinct 100 Mb 
LANs.

 

The 3H02-04 (Figure 1-2) provides connection for four independent 
100BASE-TX LANs to the ATX backplane and packet processing engine 
(PPE). It includes processing circuitry for receiving and forwarding 
packets between the connected 100BASE-TX LANs within each module. 
The 3H02-04 contains several LEDs to indicate the module’s operational 
status. Each segment has link test enabled and supports receive pair 
polarity reversal detection and automatic correction.

The 3H02-04 supports unshielded twisted pair (UTP) and IEEE 802.3 
100BASE-TX specification.
