The Network You Inherited May Not Match the Network You Were Told About
New IT team. New tenant. New facility manager. Same undocumented network.
Organisations rarely inherit ICT infrastructure exactly as it was originally designed.
A new IT team may take over from a previous team. A new tenant may move into an office with existing cabling. A facility manager may inherit communication rooms that were installed years earlier. A company may acquire another organisation, relocate offices, or take over a newly completed property.
In each situation, there is one important question:
Does the network documentation actually match what exists on the ground?
Sometimes it does.
Sometimes the drawings are outdated.
Sometimes the documentation is incomplete.
And sometimes the infrastructure has changed so much that nobody can confidently say which cables, fibre links, ports and equipment are connected to what.
This is where ICT infrastructure documentation and assessment become valuable.
The Problem With an Inherited Network
An existing network can continue operating even when its documentation is incomplete.
That can create a false sense of security.
The network works, so everyone assumes the infrastructure is understood.
Then something changes.
A switch needs to be replaced.
A department moves.
A new office is added.
A fibre link develops a fault.
A new tenant takes over.
An upgrade project begins.
Suddenly, the organisation needs answers.
Which cable serves this area?
Where does this fibre link terminate?
Which switch serves this floor?
Which ports are available?
Where is the patch panel?
Does the rack layout match the drawing?
Can the existing infrastructure support the planned expansion?
If nobody has reliable answers, technicians may have to physically trace, test and identify connections before work can proceed.
That costs time.
And more importantly, it means the organisation is managing critical infrastructure without a reliable baseline.
How Organisations End Up With Undocumented Infrastructure
ICT infrastructure evolves over time.
It can be inherited through:
- Previous IT teams
- Previous contractors
- Office relocations
- Mergers and acquisitions
- New properties
- Completed construction projects
- Tenant handovers
- Facility expansions
- Network upgrades
- Additional buildings and branches
Every project can introduce changes.
A new fibre link may be added.
A switch may be replaced.
A rack may be reorganised.
New outlets may be installed.
A department may move.
Additional access points may be deployed.
But if these changes are not reflected in the documentation, the organisation gradually develops two versions of its infrastructure:
The infrastructure that exists.
And:
The infrastructure shown on paper.
The bigger the gap becomes, the harder the network becomes to manage.
When Network Drawings Don’t Match Reality
Network diagrams and as-built drawings are important infrastructure management tools.
However, they are only useful when they reflect the current environment.
For example, documentation may show:
Rack A → Switch 1 → Patch Panel 1 → Office Area
But after several changes, the physical infrastructure may actually be:
Rack A → Switch 3 → Patch Panel 2 → New Distribution Point → Office Area
If the documentation was never updated, the original drawing may still be technically present but operationally unreliable.
This is why an ICT infrastructure assessment should not simply involve reviewing old documents.
The physical environment needs to be assessed against the available documentation.
What Should an ICT Infrastructure Documentation Exercise Capture?
The exact scope will depend on the organisation, facility and infrastructure, but a comprehensive assessment may include several important areas.
Physical Connectivity
Understanding how rooms, buildings, racks and network infrastructure are physically connected.
This establishes the relationship between the physical environment and the network.
Structured Cabling
Documenting copper cabling, outlets, patch panels, cable routes and identification.
This is particularly important for organisations planning office expansion, relocation or network upgrades.
Fibre Infrastructure
Fibre links should be identified and documented, including termination points and relevant core information.
For multi-building organisations, accurate fibre infrastructure documentation can be particularly valuable.
Network Equipment
Existing switches, routers, wireless infrastructure and other relevant equipment can be identified and associated with their physical locations.
This helps create a more accurate infrastructure asset baseline.
Rack Layouts
Communication rooms can become increasingly difficult to manage when equipment has been added over several years.
Documenting rack layouts can provide visibility into:
- Equipment positions
- Patch panels
- Switches
- Fibre termination
- Power arrangements
- Connectivity
Port Information
Port information can help connect physical infrastructure to network equipment.
This becomes useful when troubleshooting, adding new connections or planning changes.
IP Information
Where applicable and within the agreed scope, relevant IP information can be incorporated into the infrastructure record.
This helps connect the physical infrastructure with the logical network environment.
Test Results
Infrastructure documentation becomes more useful when supported by appropriate testing.
Depending on the project, testing may include fibre or copper testing and other relevant verification activities.
As-Built Conditions
Perhaps the most important question is:
What is actually installed today?
As-built documentation should reflect the infrastructure that exists—not simply what was originally designed.
Why Infrastructure Documentation Matters to Business
Network documentation is sometimes treated as an IT administrative task.
It shouldn’t be.
Accurate infrastructure information can support multiple business functions.
IT Departments
IT teams can use infrastructure documentation for troubleshooting, maintenance, upgrades and network changes.
Facilities Management
Facilities teams can gain better visibility into communication rooms, cabling routes and ICT infrastructure within the physical environment.
Procurement
Procurement teams can make better-informed decisions when preparing equipment purchases, upgrade projects and infrastructure BOQs.
Project Managers
Project teams can use existing infrastructure information when planning modifications, expansions and new deployments.
Developers and Property Owners
Property stakeholders can maintain better records of ICT infrastructure installed within their buildings and developments.
Management
Management can use infrastructure information to support budgeting, lifecycle planning and future technology investment.
The value increases when ICT, facilities, procurement, projects and management are working from the same verified infrastructure information.
Infrastructure Assessment Before Infrastructure Upgrade
One of the most important times to assess an existing network is before investing in an upgrade.
Organisations sometimes begin with a list of equipment they believe they need.
For example:
“We need more switches.”
“We need additional access points.”
“We need more fibre.”
But before developing a procurement list or BOQ, it can be useful to understand the existing infrastructure.
An infrastructure assessment can help establish:
- What equipment already exists
- What cabling exists
- What fibre infrastructure exists
- How buildings are interconnected
- How racks are arranged
- What ports and connections are available
- What has changed from the original design
- What documentation is missing
- What infrastructure requires further investigation or testing
This creates a stronger foundation for ICT infrastructure upgrades and expansion planning.
The Role of Fibrecom
At Fibrecom Solutions Ltd, we position ICT infrastructure as a long-term organisational asset.
Our role is not simply to install cables or supply equipment.
We work with organisations and their stakeholders to understand requirements, assess existing environments and deliver practical ICT infrastructure solutions.
Our approach follows a structured lifecycle:
REQUIREMENT
↓
SITE ASSESSMENT
↓
DESIGN
↓
BOQ

SUPPORT
For organisations dealing with inherited or undocumented infrastructure, the process can begin with understanding what is already installed.
Fibrecom can help assess and capture:
Physical connectivity
Structured cabling
Fibre links
Network equipment
Rack layouts
Port information
IP information
Test results
As-built conditions
The objective is simple:
Move from “We think this is how the network is connected” to “This is what we have.”
Don’t Wait for a Network Problem to Expose a Documentation Problem
The worst time to discover that your network is poorly documented is often when you need to make a critical change.
During an outage, relocation or urgent repair, technical teams need information quickly.
They should not have to search through years-old drawings.
They should not have to trace every cable unnecessarily.
They should not have to determine the infrastructure architecture through trial and error.
Good network documentation gives technical teams a starting point.
It reduces uncertainty.
It supports continuity.
And it makes future infrastructure work easier to plan.
When Should You Document Your ICT Infrastructure?
An infrastructure documentation exercise may be worth considering if:
- You have a new IT team.
- You have moved into a new facility.
- You have taken over an existing property.
- You have acquired another organisation.
- Your network has undergone several upgrades.
- Existing network drawings are outdated.
- Your organisation operates across multiple buildings.
- Fibre connectivity is poorly documented.
- Rack layouts are unclear.
- Troubleshooting frequently requires physical tracing.
- You are preparing a major network upgrade.
- You are planning an office relocation.
- You are preparing an ICT infrastructure BOQ.
- You are expanding to new locations.
- You are unsure what infrastructure you currently have.
From “We Think” to “We Know”
A well-managed ICT environment should not depend entirely on institutional memory.
When one IT manager leaves, the infrastructure knowledge should not leave with them.
When a contractor completes a project, the client should have usable documentation.
When a tenant moves out, the next tenant should be able to establish what infrastructure remains.
When a company acquires another business, it should be able to assess the inherited ICT environment.
And when a network is upgraded, the documentation should evolve with it.
The objective is not simply to create another document.
The objective is to create a reliable infrastructure baseline that people can use.
Build From What You Know
Before deciding what equipment to purchase, what infrastructure to upgrade or what new connectivity to deploy, establish what already exists.
Assess it.
Verify it.
Test it where required.
Document it.
Then plan what comes next.
Fibrecom Solutions Ltd works with organisations, ICT teams, facilities teams, project managers, procurement teams, developers and contractors to assess, design, supply, deploy, test and document ICT infrastructure.
If your organisation has inherited a network and the documentation doesn’t tell the whole story, let’s establish what you actually have.
