This fan option is fully compatible with HP BladeSystem c7000 and c3000 enclosures, as well as any c-Class chassis that support FIO fan modules.
How do I install the HP BLc 6X Active Cool 200 FIO Fan Option?
Simply slide the module into an empty FIO fan slot in a powered-off or hot-swap-allowed c-Class enclosure until it clicks into place; the enclosure auto-detects the fan and adjusts airflow.
Is the fan module hot-swappable without downtime?
Yes. The HP BLc 6X Active Cool 200 FIO Fan Option supports hot-swap operations, allowing you to replace or add fans without powering down the BladeSystem.
What cooling capacity does this fan option provide?
Each module delivers up to 200 cubic feet per minute (CFM) of airflow across six high-speed fans, ensuring efficient heat dissipation for densely populated blade servers.
What is the noise level of the HP Active Cool 200 fan module?
Under typical load, the module operates at approximately 52 dBA, balancing high cooling performance with acceptable sound levels in data-center environments.
How much power does the fan option consume?
The six-fan module draws a maximum of 50 watts under full speed, with dynamic power management reducing consumption during lower thermal loads.
Does the HP BLc 6X Active Cool 200 support redundant cooling?
When installed in pairs or with existing FIO fan modules, it provides N+1 redundancy to maintain cooling even if one fan module fails.
How many fan modules are recommended per enclosure for optimal cooling?
HP recommends installing at least four 200 CFM fan modules in a c7000 enclosure and two in a c3000 chassis to achieve proper airflow and redundancy.
What are the physical dimensions and weight of the fan module?
The unit measures 6.8 x 1.0 x 7.5 inches (W×H×D) and weighs approximately 0.7 pounds, fitting standard full-height c-Class FIO slots.
