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.

How Netcomtech tools work
CALCULATED

Derived directly from the values you enter.

REFERENCE

Technical statements are tied to published standards or authoritative documentation.

USER ASSUMPTION

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.

NETWORK PLANNING

IPv4 Subnet Calculator

Show the calculation

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

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.

ItemIdentifierLocation / UManagement IP / referenceNotes

Do not place passwords, private keys or other secrets in a handover sheet intended for general circulation.

PLANNING LIBRARY

Infrastructure areas this section will cover

The framework is deliberately broader than servers and covers the physical and logical infrastructure lifecycle.

Media, connectors, transceivers, link loss, polarity, testing and documentation.

Wireless

AP requirements, wired uplinks, PoE, deployment inputs and survey considerations.

Racks & cabinets

Rack units, depth, rails, cable management, airflow, PDUs and equipment layouts.

Power & UPS

Electrical load, VA, power factor, UPS planning, PDU loads and power-path resilience.

Storage

RAID capacity, usable storage, growth allowances and backup capacity planning.

Servers

Rack space, power, storage and component concepts without depending on current stock.

Installation

Pre-installation surveys, commissioning, testing, cable schedules and handover records.

Documentation

Rack elevations, port schedules, IP plans, cable records and equipment schedules.

Resilience

Redundant paths, N+1 concepts and identifying single points of failure.

Data centre planning

Rack density, power, cooling inputs, structured cabling and capacity documentation.

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.

UPS selection

Schneider Electric identifies load assessment, UPS capacity, topology and runtime as important selection considerations. Runtime is specific to the UPS and load.
