What Are The Features Of 84/30 Server Rack Models?
84/30 server racks are standardized units measuring 84 inches tall with 30 rack units (RU) of vertical mounting space. They typically support loads up to 2500 lbs and feature 19″ width compatibility for enterprise hardware. Advanced models include perforated doors for airflow management and adjustable depth (1000-1200mm range).
What cooling systems work best with 84/30 racks?
High-density deployments require hot/cold aisle containment paired with vertical exhaust ducts. For every 1kW load, allocate 120 CFM airflow. Blade servers often need rear-door heat exchangers maintaining 22°C±2 inlet air.
How do 84U racks compare to 42U models?
| Feature | 84U | 42U |
|---|---|---|
| Max Weight Capacity | 2500 lbs | 1500 lbs |
| Typical Power | 30kW+ | 10-15kW |
While 84U racks double vertical space, they require reinforced flooring (500 lbs/ft² vs 200 lbs/ft²). Their 36″ depth accommodates full-size UPS systems unlike 42U’s 24″-29″ range.
FAQs
Only models with base isolation plates and cross-brace reinforcement meet IEEE 693 Zone 4 standards (0.5g lateral force).
What’s the lead time for custom 84/30 racks?
Allow 8-10 weeks for NEMA 12 enclosures with EMI shielding – powder coating alone takes 14 days curing.
