Authenticate to load engineering data. No telemetry or engineering approval is assumed.
1. Electrical source topology
Document upstream infrastructure from utility/switchgear to UPS and PDU/busway. All entries are operator supplied.| Source | Domain | Design limit | Upstream |
|---|
2. Rack design and A/B power feeds
A and B each reserve the full design peak for a fault scenario. Downstream / upstream reservations are analyzed against documented source limits.3. Cooling plant and liquid loop
Flow estimate assumes water at approximately 1 kg/L and 4.186 kJ/kg/K. Glycol mixes, pump head and pressure drops require qualified engineering calculations.4. Calculated rack assessment
Choose a rack and calculate to view source paths, thermal split, and warnings.
5. Evidence & independent review
The submitted engineering configuration is hashed. Changes to the model or evidence invalidate the prior review.| Review | Status | Current? | Action |
|---|
6. Human-notification handoff register
No external emails, pages, ITSM tickets, or notifications are transmitted. This records the operator's external communication reference only.| Notice | Channel | Reference |

Engineering disclaimer: Documented independence is not proven upstream electrical independence. Electrical code review, protective-device coordination, qualified mechanical and liquid-cooling design, controlled failure testing, OEM validations and site acceptance remain mandatory before energizing any 120 kW rack.
