Busbar Adapter Test Stand for Rack-Free Server Power Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rack servers without internal power supplies require installation in a rack for testing, complicating testing in laboratory and special environments due to the need for custom setups and heavy, cumbersome test racks with non-standard power sources.
Innovation Solution
A portable test stand with a built-in power module and busbar adapter that allows devices to be powered independently of a rack, using a standard 110V wall outlet, minimizing footprint and enabling easy reconfiguration for different devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a custom rack with rack-level power source is used to test servers without internal power supplies, then the servers can be powered and tested, but the test rack becomes heavy and cumbersome requiring pallets for movement
Solution Approach 1:
The invention separates the power supply function from the rack structure. Instead of integrating a rack-level power source into a heavy custom rack, the solution uses a standalone power module that can be detached and moved independently. The power module connects to the server via a busbar adapter, allowing the testing setup to be lightweight and mobile while maintaining full power supply capability.
Solution Approach 2:
The power supply unit is extracted from the rack structure and placed in a separate, portable module. This extraction eliminates the need for a heavy custom rack, as the power module can be positioned anywhere within testing environment and connected to the server without requiring a permanent rack installation.
2Reliability
If a custom rack with powershelf and PSU is used for testing, then servers can be powered, but the device complexity and setup requirements increase
Solution Approach 1:
The invention combines the busbar adapter and power connection interface into a single integrated component. The busbar adapter attaches to the server's existing busbar and provides direct power connections, eliminating the need for separate powershelf, PSU, and whip assemblies. This merging simplifies the overall testing setup while maintaining reliable power supply.
Solution Approach 2:
The busbar adapter serves multiple functions: it provides electrical power connections, mechanical support for the power module, and a standardized interface for different server configurations. This multi-functionality reduces the number of separate components needed and simplifies the testing setup process.
3Reliability
If rack-mounted testing is used for servers without internal power supplies, then power can be supplied, but mobility and ease of reconfiguration are reduced
Solution Approach 1:
The invention creates a dynamic, reconfigurable testing setup where the power module can be easily moved and repositioned. Unlike fixed rack-mounted configurations, the standalone power module can be relocated to different testing positions, allowing flexible adaptation to various testing environments and configurations without permanent installations.

AI summary
An apparatus provides power for computer devices, such as servers, facilitating their testing outside of the typical server rack. A platform of supports the computer device while providing for a power supply unit beneath the platform to be connected to the device. The location of the power supply beneath the platform decreases the combined footprint of the apparatus and device under test. The power supply unit may be configured to connect to standard voltages, allowing the computer device to be tested where connection to rack-level voltage is not convenient.
