How to Trace Unknown Network Cables with Noyafa NF-859GS Malaysia
How to Trace Unknown Network Cables with Noyafa NF-859GS Malaysia
One of the most common problems faced by network technicians is identifying an unknown Ethernet cable.
In a network cabinet containing dozens or even hundreds of cables, labels may be missing, damaged or no longer accurate. Manually disconnecting cables one by one is time-consuming and may interrupt active network connections.
The Noyafa NF-859GS Multifunction Network Cable Tester provides a Cable Scan function to help technicians trace and identify network cables more efficiently.
For IT technicians, CCTV installers, network contractors and maintenance teams in Malaysia, cable tracing can significantly reduce troubleshooting time.
Why Do Network Cables Become Difficult to Identify?
A new network installation may initially be well organised and properly labelled.
However, over time, changes are often made.
New network points are added, equipment is relocated, switches are replaced and CCTV cameras or wireless access points may be installed.
Eventually, technicians may encounter:
Missing cable labels
Incorrect cable labels
Unknown RJ45 cables
Unidentified wall outlets
Unclear patch panel connections
Unknown switch connections
This is where a network cable tracing function becomes useful.
Use Cable Scan to Find the Target Cable
The Cable Scan function of the Noyafa NF-859GS helps technicians trace and identify a target network cable.
Instead of manually checking every Ethernet connection, the technician can use the tester to assist with identifying the required cable.
This is especially useful in network cabinets containing many similar-looking cables.
Trace Cables Between Wall Outlets and Network Cabinets
In an office building, a technician may know which wall network outlet has a problem but not know which cable inside the communication room belongs to that outlet.
Cable tracing can help identify the corresponding cable.
This is useful when troubleshooting network points for:
Computers
Printers
IP phones
CCTV cameras
Wireless access points
Access control systems
Other network equipment
Once the correct cable has been identified, further testing can begin.
Useful for CCTV Cable Identification
Large IP CCTV systems can contain many Ethernet cables connected to PoE switches.
When one camera goes offline, technicians first need to identify the cable connected to that camera.
The NF-859GS Cable Scan function can assist with cable identification.
After locating the cable, technicians can continue checking continuity, PoE and the corresponding switch port.
This makes the NF-859GS particularly useful for CCTV maintenance.
Identify the Corresponding Switch Port
After tracing the Ethernet cable, technicians may also need to determine which switch port it is connected to.
The NF-859GS includes a Port Flash function to assist with network switch port identification.
Cable Scan and Port Flash provide two useful functions for technicians working with complicated network cabinets.
Check the Cable After Identification
Finding the correct cable does not necessarily explain why the network connection has failed.
Once the cable has been identified, technicians can use the NF-859GS to perform additional tests.
The tester provides cable continuity testing to help check the wiring condition.
This can help determine whether the problem may be related to the physical cable or its termination.
Measure the Network Cable Length
The NF-859GS supports Ethernet cable length measurement from approximately 2.5 to 200 metres.
This is useful when the cable route cannot easily be followed physically.
Network cables may run:
Above ceilings
Inside walls
Through conduits
Under raised floors
Along cable trays
Between different rooms or floors
Cable length information provides technicians with additional information during troubleshooting.
Check PoE Connections
Many network cables now carry both data and electrical power through PoE.
Common PoE devices include:
IP CCTV cameras
Wireless access points
VoIP phones
Access control equipment
The Noyafa NF-859GS includes PoE testing capability, allowing technicians to perform additional troubleshooting after identifying the correct cable.
This is particularly useful when the connected device does not power up correctly.
Useful When Taking Over an Existing Network
Network contractors are often asked to maintain systems that were originally installed by another company.
Documentation may be incomplete or unavailable.
In these situations, technicians may need to identify the existing network infrastructure before making any changes.
The NF-859GS can assist with:
Cable tracing
Continuity checking
Cable length measurement
Port identification
PoE troubleshooting
RJ45 termination checking
This can make it easier to understand an existing network installation.
Useful for Network Re-Labelling Projects
Cable tracing is also useful when reorganising a server room or network cabinet.
Technicians can identify cables and create new labels for:
Patch panels
Network cables
Wall outlets
Switch ports
CCTV connections
Wireless access points
Accurate labelling can make future network maintenance much faster.
More Than a Cable Tracer
The Noyafa NF-859GS is not only a cable tracing tool.
It combines:
Cable Scan
Cable Continuity Test
Cable Length Test
QC Test
PoE Test
Port Flash
NCV Detection
LED Lighting
It also includes a 10mW Visual Fault Locator (VFL) for basic fibre optic troubleshooting.
For technicians who perform different network maintenance tasks, this multifunction design can reduce the need to carry several separate basic testers.
Where Can the NF-859GS Be Used?
The NF-859GS is suitable for cable tracing and network troubleshooting in:
Network cabinets
Server rooms
Data centres
Offices
CCTV installations
Factories
Warehouses
Hotels
Schools and universities
Commercial buildings
