About This Document
This document provides instructions for servicing the High-Performance Process Manager (HPM). The
instructions consist of fault isolation and removal/replacement procedures at the Optimum Replaceable Unit
(ORU) parts level.
ATTENTION
With TPN R684, Enhanced Universal Control Network (EUCN) is introduced.
In EUCN, the traditional coaxial cable system is no longer utilized and is
replaced with a Fault Tolerant Ethernet (FTE) based communication network.
Throughout the document, unless specifically mentioned, the terms HPM,
NIM, and UCN are interchangeably used with the terms
EHPM, ENIM , and
EUCN respectively.
ATTENTION
With TPN R686, the Enhanced Network Bridge (ENB) is introduced. The
ENB is a variant of the NIM that allows communication between the LCN and
both UCN and EUCN networks. It can communicate over coaxial-based UCN
and FTE-based EUCN communication networks and provides a gateway
function between the UCN and the EUCN. The ENB also facilitates on-
process migration from HPM to EHPM (assuming you have redundant
HPMs).
ATTENTION
Beginning with TPN R686, Fieldbus support is withdrawn.
