NETWORK PLANNING
TOOLS & PLANNERS
Plan infrastructure with calculations you can inspect.
Practical calculators for networks, racks, power, storage and installation planning. Inputs, formulas and assumptions remain visible so the result can be checked.
Derived directly from the values you enter.
Technical statements are tied to published standards or authoritative documentation.
Planning allowances you choose are shown separately and are never presented as mandatory requirements.
WORKING TOOLS
Calculate and plan
These tools run entirely in your browser. They do not select a product or pretend to engineer an installation.
POWER OVER ETHERNET
PoE Budget Planner
Enter device groups using the maximum or allocated power value appropriate to your planning method.
Show the calculation and technical basis
NETWORK CAPACITY
Data Transfer Time Calculator
Show the calculation
RACKS & CABINETS
Rack Unit Planner
Planning note
Rack units describe vertical mounting space. They do not confirm equipment depth, weight, rail compatibility, airflow clearance, cable bend radius, PDU mounting or cabinet load rating. Those must be checked separately against the equipment and cabinet specifications.
POWER & COOLING
Electrical Load & Heat Calculator
Show the calculation and limitation
Important: electrical load converted to heat does not by itself size an air-conditioning system. Room heat gains, UPS losses, lighting, people, environmental conditions, redundancy and the cooling design must also be considered.
STORAGE
RAID Capacity Calculator
Show the calculation and limitation
Nominal capacity is based on equal usable capacity per drive, limited by the smallest drive. Controller metadata, filesystem overhead, formatting and vendor implementation can reduce space available to applications. RAID is not a backup.
SECURITY & STORAGE
Camera Recording Storage Calculator
Show the calculation and limitation
This is a bitrate-based data-volume calculation. Actual variable-bitrate recording depends on scene complexity, codec, frame rate, resolution, motion and camera settings. NVR overhead and storage protection are not included.
NETWORK INSTALLATION
Switch Port Capacity Planner
Show the calculation
This counts physical access ports only. It does not determine switch architecture, uplink bandwidth, stacking, redundancy, VLAN design, PoE capacity or oversubscription.
RACKS & CABINETS
Visual Cabinet Builder
Build a rack elevation by adding equipment in rack units. This plans vertical U-space only.
What this result does and does not establish
CALCULATED Used and remaining rack units are arithmetic from the U values entered. A rack unit is a vertical mounting measure. This tool does not establish cabinet depth, equipment weight, rail compatibility, airflow, cable bend radius, power distribution, thermal suitability or cabinet load capacity. Verify those against the actual equipment and cabinet specifications.
FIBRE
Fibre Link Loss Budget Worksheet
Calculate planned passive link loss from values you enter. Use the limits from the applicable project standard, application specification and component manufacturer.
Show the calculation and technical basis
REFERENCE Optical loss budgets include fibre length and connection/splice losses. Application limits and component values vary, so this tool deliberately requires those values to be entered rather than silently assuming a fibre type or application.
STRUCTURED CABLING
Structured Cabling Capacity Planner
Turn outlet quantities into termination and patch-panel capacity. This is a quantity planner, not a standards compliance certificate.
Show the calculation and limitation
This tool does not determine cable category, maximum link length, pathway fill, separation from power, fire rating, earthing/bonding, test limits or local regulatory requirements. Those depend on the installation and applicable standards.
NETWORK DOCUMENTATION
Network Topology Sketcher
Create a simple logical overview from device counts. It documents what you enter and does not infer a network architecture.
Planning limitation
The diagram is a logical documentation sketch only. It does not validate redundancy, routing, VLANs, spanning tree, firewall policy, uplink capacity, switch stacking, high availability, broadcast domains or physical cabling.
UPS & POWER
UPS Candidate Checker
Compare an entered load with a specific UPS candidate's published W and VA ratings. Runtime is only checked when you enter a manufacturer-published runtime for that candidate and load.
Show the checks and limitation
REFERENCE UPS selection requires both W and VA load/capacity to be considered. Runtime depends on the specific UPS, battery system and load. Netcomtech does not estimate runtime from VA alone.
INSTALLATION
Installation & Commissioning Worksheet
Create a printable checklist for an infrastructure installation. The checklist records verification; it does not certify compliance.
DOCUMENTATION
Infrastructure Documentation Sheet
Build a simple printable handover record for a rack, communications room or installation.
| Item | Identifier | Location / U | Management IP / reference | Notes |
|---|
Do not place passwords, private keys or other secrets in a handover sheet intended for general circulation.

TECHNICAL BASIS
Sources and boundaries
Netcomtech separates arithmetic from reference information. IEEE 802.3 defines Ethernet and standardized PoE, including four-pair PoE introduced by IEEE 802.3bt. Cisco documentation shows that PoE switches detect/classify powered devices and account for allocated power against the switch budget. Fluke Networks documents standards-based copper cabling performance and the specific limitations around 10GBASE-T on Category 6 compared with Category 6A. Schneider Electric publishes data-centre heat-load calculation guidance.
Technical review: September 2026. Calculators are planning aids, not substitutes for site surveys, engineering design, manufacturer compatibility checks or certification testing.
TECHNICAL BASIS
References used for these planning tools
Where a tool depends on project-specific or manufacturer-specific limits, Netcomtech asks you to enter the verified value rather than inventing one.
Fibre loss planning
Fluke Networks explains that link-loss budgets include fibre length, connectors, splices and other passive components, and that application limits must also be respected.
Fluke Networks: loss budgetsUPS selection
Schneider Electric identifies load assessment, UPS capacity, topology and runtime as important selection considerations. Runtime is specific to the UPS and load.
