13 Understanding Alarms & Reporting

13.1 Alarms

The term Event is a generic term for any occurrence in the system that could cause an entry in the

Event Log to be generated. Events are defined into four categories.

• Loss of Service

• Service warning

• Hardware Warning

• Informational

Some events also cause alarms and are sub-divided as described in the following sections. All these

event types are recorded in the log files accessible in the Configuration GUI. See ”Event Log”.

13.1.1 Loss of Service

This occurs when the Primary Hub detects an event that will result in the complete loss of 1 or more

services in at least 1 RU location, e.g. a link calibration failure, Overload “Safe Mode”, RU

communication timeout, thermal shutdown, etc.

A typical example of a Loss of Service alarm occurs when a Remote Unit is disconnected from the

system.

The log file will show the following type of behavior.

2020-03-31 16:40:47: Raised loss of service alarm: Device is missing on Optical

Remote Unit S/N: 660102004510 RU System

Description

Action

Calibration error

An error has occurred in the

calibration of an optical link.

Either carry out a manual recalibration

through the System Maintenance page or

remove and replace the optical cable

which will force a recalibration to occur. If

the fault persists, check the equipment at

both ends of the affected link.

RU services are restricted

by a missing Service

Module, or by matrix

settings

The system cannot be configured

as desired and some services will

not be present due to incomplete

Matrix settings.

Check that each Matrix has valid input

and output paths set
