Chapter 3: Maintenance and Component Installation
System Cooling
Eight hot-swapable 9-cm counter-rotating fans at the rear of the chassis provide the cooling
for the system. Each fan unit is made up of two fans joined back-to-back, which rotate in
opposite directions. This counter-rotating action generates exceptional airow and is e󰀨ective
in dampening vibration levels.
Replacing Fans
Fan speed is controlled by system temperature via IPMI. If a fan fails, the remaining fans
will ramp up to full speed. Replace any failed fan at your earliest convenience with the same
type and model (the system can continue to run with a failed fan).
Replacing a System Fan
1. Inspect the rear of the chassis to determine which fan requires changing.
2. Squeeze both release tabs on the fan simultaneously and gently pull the fan from the
housing (see gure below). The fan's wiring will automatically detach.
3. Place the new fan into the vacant fan space and push in until it clicks into place.
