• There is at least 50 mm (2 in.) of ventilated space at the sides of the appliance and 100 mm (4 in.) at the rear of the appliance.
• The top cover is removed for no longer than 30 minutes while the appliance is operating.
• The processor housing cover covering the processor and memory area is removed for no longer that 10 minutes while the appliance is operating.
• A removed hot-swap drive is replaced within 2 minutes of removal.
• Cables for optional adapters are routed according to the instructions provided with the adapters (ensure that cables are not restricting air flow).
• The fans are operating correctly and the air flow is good.
• A failed fan is replaced within 48 hours.
