This Troubleshooting Manual describes fault-clearing procedures to be performed in reaction
to alarm events that may occur in the FLASHWAVE 4570 system.
1.1 Intended Audience
This document is intended for anyone tasked with clearing fault conditions to restore normal
system operation. Personnel performing these procedures must have general experience
with Synchronous Digital Hierarchy (SDH) transport networks as well as specific experience
with Fujitsu FLASHWAVE 4570 hardware components and network management software.
Personnel must also comply with all relevant safety practices whenever working with
FLASHWAVE 4570 equipment.
1.2 Structure of This Document
Alarm lists
When a fault condition occurs, the relevant alarm notification will be generated and displayed
on craft terminal screens. All FLASHWAVE 4570 alarms are listed in the Alarm lists in
Chapter 2. The alarm lists are divided into separate tables that match the fault categories as
presented on craft terminal screens. These categories are as follows:
Equipment alarms
Communication alarms
Environment alarms
Quality of Service (QoS) alarms
Security alarms
Troubleshooting
For each entry in the Alarm lists, specific fault-clearing procedures are contained in Chapter
3, Troubleshooting. Click the desired alarm name in the Alarm list to jump directly to the
instructions for that alarm.
Described Features
Some features described in this document may not be available. To identify the features
released for your project, please refer to the Release Note delivered together with the
product.

FLASHWAVE 4570 alarms are divided into the following categories:
Equipment alarms: originate from specific hardware elements (e.g., traffic card, controller
card, shelf, etc.) Communication alarms: originate from termination points which represent a particular
function of the network
Environmental alarms: originate from telemetry sensors that monitor conditions/ events
external to the Network Element (NE)
Quality of Service alarms: originate from termination points where performance
measurement and threshold supervision is enabled
Security alarms: originate from termination points which detect the system authentication
and authorization
