Cooling fans
Isilon IQ nodes contain three cooling fans to prevent the node components from overheating.
General ESD guidelines
Always follow electrostatic discharge (ESD) prevention procedures when removing and replacing cards, memory, and other
system components. You must use a wrist strap, attached to the node chassis, for grounding.

Replacing a cooling fan
Isilon nodes contain three cooling fans to maintain proper airflow. Each cooling fan can be individually replaced without
powering down the node.
1. Remove the top panel from the node.
For more information, see
on page 38.
Note: Removing the top panel from a node temporarily places the node into a read-only state. The node
returns to a read/write state when the top panel is replaced.
2. Identify the fan you want to replace.
A small red fan fault LED at the rear base of each fan indicates the fan to replace. The following figure shows the
location of each fan.
