LET61
The LET61 port processor (Part #030020-001) is a high performance Ethernet router
interface using a Motorola 68340 CPU. The LET61 port processor supports 10Base-T,
10Base-2 (using the LEC01 Thinnet Ethernet adapter), and AUI (using the LAU01 AUI
Interface adapter) connections. The LET61 port processor may be used for routing,
bridging, and IENView access.
LET61B
The LET61B port processor (Part #030020-004) is a high performance Ethernet interface
using a Motorola 68340 CPU. The LET61B port processor is used strictly for IEN bus
extension, or as a bus monitor. The LET61B port processor supports 10Base-T, 10Base-2
(using the LEC01 Thinnet Ethernet adapter), and AUI (using the LAU01 AUI Interface
adapter) connections.
LET61H
The LET61H port processor (Part #030020-002) is a high performance Ethernet interface
with a 1MB memory expansion capability. The LET61H port processor is used for routing,
bridging, and IENView access at a central site.
Figure 3-27 illustrates the bus communications for the LET61, LET61B and LET61H port
processors.
