Technical Overview

System Diagnostic Controller

This diagnostic controller is composed of a Z-80 microprocessor and its supporting logic. The diagnostic controller is designed to control the power-up sequencing of modules, monitor the 9H531-17 and 9H532-17 input and output power parameters, keep watch over the main host processor, as well as monitor the temperature and control the SMB LANVIEW diagnostic LED. Although the diagnostic controller and the main host processor can operate independent of each other if needed, they exchange information about each other’s status and overall module condition. The information gathered by the diagnostic controller is available to the network manager via local/remote management and the LCD located on the Environmental Module. The 9H531-17 and 9H532-17 have been designed so that in the event of a diagnostic controller fault, the 9H531-17 and 9H532-17 will continue to function.

DC/DC Converter

The DC/DC converter converts the 48 VDC on the system power bus to the necessary operating voltages for its host network services module. The diagnostic controller monitors and controls the operation of the DC/DC converter.

INB Interface

Each module attaches to both INB A and INB B and has two INB ASICs. The INB ASICs use 64-byte Ethernet frames for transmission onto the INBs at 66 MHz.

The 9X5XX modules are fully compatible with the first generation 9X4XX modules. The first generation modules communicate only on INB B using a

56-byte canonical frame format, at 40 MHz. If the newer module detects a first generation module on the backplane, it automatically changes from the fast

66 MHz Ethernet frames, to the first generation compatible 40 MHz canonical frame on INB B only. INB A is used only by the 9X5XX modules and remains at the higher speed.

i960 Core

The i960 core provides modules host services, the SNMP protocol stacks, to support industry standard MIBs, as well as Cabletron enterprise extension MIBs for each media type. Management services, such as telnet, WebView and network address to MAC address mapping, are also provided by the i960 core.
