IT & Networking · 50+ users, multiple floors or buildings
Business and site network
Start with a site survey. Explore two floors connected by fibre, two internet services with failover, a dedicated firewall, managed Wi-Fi, shared services and power protection at each rack.
Explore the network
Start with a site survey. Follow the copper-coloured fibre from the site core to Floor 1 and Floor 2. Select any device for its role and survey checks. F1 and F2 mean Floor 1 and Floor 2; icons represent equipment roles, not quantities.
- Fibre backbone / provider line
- Ethernet cable (Cat6)
- Power protection
- Wi-Fi

What a site survey covers
A larger site needs measured requirements before an equipment schedule. We assess these areas with you, then document the proposed network and installation scope.
Buildings, floors and cable paths
Map racks, desks, outlets and inter-building routes; measure distances and inspect access, containment and physical protection.
Internet and continuity
Check provider availability, route diversity, handovers, upload demand and acceptable downtime; agree failover and recovery tests.
Users and applications
Identify wired and wireless users, business workloads, growth, remote access and dependencies on shared services.
Wi-Fi coverage
Measure coverage, interference and client demand; confirm access-point placement, central management and guest separation.
Security and segmentation
Document staff, guest, CCTV, services and management access; agree permissions and verify isolation and authorised traffic.
Racks, PoE and power
Inspect rack space, ventilation, earthing and power; measure loads and select protected-power cover from equipment specifications.
Storage, recording and recovery
Confirm file growth, camera streams, recording retention, backups, off-site copies and restore requirements.
Testing and handover
Agree cable and fibre tests, failover checks, coverage verification, labels, port maps and operational documentation.
Design notes
- This representative topology is a starting assumption for Peter to review. Floor labels show physical locations; dashed Services and CCTV boxes show logical network groups. It is not a measured plan or a fixed equipment schedule.
- Two internet services provide alternative provider paths when failover is configured and tested. They do not duplicate the firewall, core switch, floor uplinks or power source. Agree acceptable downtime and recovery needs before choosing hardware or path redundancy.
- The floor switches connect to the core by fibre. Confirm routes, distance, fibre type, compatible interfaces, termination, testing and physical protection during the survey.
- Centrally managed Wi-Fi still needs coverage testing. Walls, interference, client demand and movement between floors affect placement and configuration.
- Separate staff, guest, CCTV, service and administration traffic with VLANs and explicit access rules. Verify required applications and printing across permitted paths, and test guest isolation.
- Provide protected power at every rack and provider handover. Include PoE devices in measured switch loads, use equipment runtime charts and document shutdown and recovery procedures.
- Treat shared files, backups and CCTV retention as separate requirements. Document access, keep a separate off-site backup and test restores before handover.
Plan your site before choosing equipment
Book a site survey so we can confirm the floors or buildings, users, applications, fibre routes, Wi-Fi coverage and power arrangements. The result is a documented scope based on your site.
