Telecommunications Remote Backup Cabinet Solution
GENX & OPTUS
An existing client, Genx, approached TROPAC with a requirement to support Optus remote backup telecommunications infrastructure through a custom cabinet solution. The brief required a compact, lightweight design capable of single-person handling, incorporating ventilation, gland plates, padlockable access, and integrated power protection components.
Working directly with both Genx and Optus, TROPAC progressed through multiple design reviews and prototyping phases in collaboration with manufacturing partners to develop a fully assembled, deployment-ready solution. Following in-field trials, further refinements were made to accommodate a dedicated battery compartment and separate control section, resulting in a redesigned, stackable two-cabinet system.

The final design was approved and confirmed for national rollout to support Optus emergency backup network infrastructure.

PROJECT PROCESS
CLIENT BRIEF
TELECOMMUNICATIONS
Genx initially approached TROPAC requesting a custom cabinet solution to support Optus infrastructure, specifically targeting backup coverage systems suited to their mobile network requirements.
Following initial engagement, TROPAC entered into direct discussions with Optus to work through technical requirements in detail. Through an iterative design and development process, a prototype solution was established — outsourcing cabinet manufacture nationally, with internal power and data accessories installed and wired in-house to deliver a complete, client-ready solution. Optus then fitted the completed cabinet with their mobile system hardware.
Following the success of the initial prototype, Genx submitted further requests requiring a full design redesign. The revised solution needed to accommodate a dedicated battery system in the lower section of the cabinet, with a separate control section housed in the upper compartment. After multiple design iterations and client feedback cycles, two finalised prototypes were produced and submitted for client review.
Optus confirmed satisfaction with the final design and advised the solution will be rolled out nationally as part of their emergency backup coverage infrastructure, providing continuity of mobile coverage during network downtime events.
PROJECT PROCESS & PROTOTYPES
PRODUCTS SUPPLIED
- 20 x custom-manufactured lightweight cabinet fitted with 19-inch rack unit rails for equipment mounting. Access is secured via a flush, padlockable chrome swing handle with an 18mm cam lock. Power distribution is through a 4-pole MCB cover (IP66) mounted on a 3-module back box, supported by two miniature circuit breakers — a 10A 1P 6kA and a 6A 1P 10kA, both C-curve rated. An IP66-rated 10A 3-pin 250V appliance inlet provides the power connection point, with 6mm earth and neutral DIN terminals for wiring terminations.
- Thermal management is provided by a 150×150mm filter fan rated at 58m³/hr for 48VDC, complemented by filter vents in both 150×150mm and 204×204mm sizes. All ventilation components are UV-rated, IP55-compliant, and fitted with high-efficiency G4 filter media.
