Best Practices
- UPS at bottom (U38-42) — heaviest
- Servers in mid-rack (U15-30)
- Patch panel near switch (+/- 2U)
- Cable mgmt between PP and switch
- PDU adjacent to UPS

Runtime Calculation
Each server draws 500 W. The UPS is rated at 3000 VA
with a power factor of 0.9 (2700 W usable). With 3 servers running,
how many minutes can the UPS sustain load?
Hint: Runtime (min) = (Watt-hours x 60) / Load (W). Assume 1 kWh battery capacity at 82% charge.

Server Power Redundancy
Toggle each server between single and dual power supply (dual recommended for production).
Place servers in the rack first.
Configuration Verification
Submit your rack configuration for evaluation. All 10 checks must pass to complete the lab. Ensure you have placed all required devices, configured environmental thresholds, set power redundancy, and selected the correct fire suppression type.
