Application
This unit describes the skills and knowledge required to remove and replace electronic circuit boards and associated equipment in switching, transmission, fixed, mobile radio, access and site environmental management networks, including the various transmission path components.
It applies to linesworkers, technicians or technical supervisors working for carriers, or other service providers. It also applies to work, which may be performed under direction of the relevant authority.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare for hardware replacement | 1.1 Obtain repair/replacement brief, relevant legislation, codes, regulations and standards for the job 1.2 Discuss and record details of hardware to be removed or replaced, and proposed work schedule with the relevant authority 1.3 Inspect network and determine the scope of the repair task 1.4 Work safely according to relevant safety legislation and client practices 1.5 Obtain appropriate new or replacement hardware and associated installation documentation 1.6 Obtain tools and check they are in good working order 1.7 Undertake an impact risk assessment of the hardware replacement with the relevant authority and prepare a contingency plan |
2. Replace hardware | 2.1 Notify relevant authority of any building or equipment cabinet alarms that might be activated by accessing site 2.2 Verify serial/part numbers of replacement card 2.3 Determine card suite, rack, shelf and slot location 2.4 Remove and replace connecting cables and card as required 2.5 Replace electronic equipment, as instructed by the relevant authority, following relevant anti-static precautions 2.6 Complete associated jumpering or cabling as required 2.7 Request relevant authority or integration team to activate the card 2.8 Escalate any hardware replacement problems with the relevant authority and implement contingency plan 2.9 Restore pressurisation systems as required |
3. Clean up worksite and complete required documentation | 3.1 Remove and dispose of waste and debris from worksite, according to environmental requirements, and restore work area 3.2 Recover faulty equipment and return to appropriate point for disposal or refurbishment 3.3 Complete documentation, update fault records and make recommendations according to the client practices 3.4 Notify relevant authority of job completion and obtain sign-off |
Evidence of Performance
Evidence of the ability to:
interpret, discuss and confirm required work
obtain documentation, equipment and hardware for required work
notify relevant personnel of alarms that could be activated in the access and restoration of equipment cabinets and enclosures
prepare a contingency plan to use if card replacement is unsuccessful, in consultation with relevant personnel
remove and replace circuit boards as instructed by relevant authority, following work health and safety (WHS) requirements and anti-static precautions
replace telecommunications hardware according to client practices
follow required practices or contingency plan if hardware replacement is unsuccessful
update fault records and complete required documentation
restore site to required condition
liaise with personnel from relevant authority for information and reporting purposes.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
explain application of direct current (DC) and alternating current (AC) electrical principles to the removal and replacement of circuit boards
describe static electricity and its impact on electronic circuit boards in telecommunications equipment
outline performance testing and fault finding techniques of telecommunications networks
describe the purpose and operation of common testing equipment
describe the behaviour of faulty network elements including symptoms and impact on network
summarise common telecommunications hardware and network structures
list types of power sources used in telecommunications networks.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications networks engineering field of work and include access to:
a suitable site to replace telecommunications network hardware
a range of hardware currently used in industry
a range of general and test equipment required for testing telecommunications network hardware.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
