Twoaie: Network Rack Layout

April 9, 2026

The Twoaie: Network Rack is built around a Tecmojo 20U 4 Post Open Frame Rack. The front of the rack only has 18U of rack space due to the design and structure of the rack which has a 1U support brace at the top of the rack, and another 1U support brace at the bottom of the rack. The rear of the rack has 16.5U of rack space owing to a larger support braces at the top and bottom of the rack.

The Twoaie: Network Rack is structured on the hierarchical (tiered) topology — a hybrid network that integrates the star and bus topologies within the design — that organise the network equipment into distinct layers: access, distribution, and core. This design improves performance, scalability, and management of complex networks by defining clear, and logical roles and functions of each layer.

NOTE: I have written down the RU (Rack Unit) position of a node or fixed asset in the rack – noting the height in rack units – starting from the bottom of the rack and counting upwards.

Top Shelf (Aerag: Antenna Array)

On top of the network rack sits the Aerag: Antenna Array with two "Poynting MIMO-4-4-V2 Antennas" that connect to the Grinney: Gateway Cluster in RU 14.
