Replace a Pilot Fan Module
If a fan module fails, the
Pilot internal temperature rises quickly. If the
temperature exceeds normal thresholds, the system issues critical alerts. Replace
fan modules as soon as possible to prevent high-temperature buildup.
Prerequisites:
•
Before handling a component, touch a grounded surface to discharge any
static electricity.
• Aach an electrostatic discharge (ESD) wrist strap to your wrist, and stand
on an ESD mat while replacing components.
• If you need to replace multiple fan module, replace only one fan module at a
time and within ve minutes.
• Initiate Guided Maintenance only when you are able to replace the fan
module immediately.
Each Pilot has four fan modules that are located side-by-side at the center inside
the Pilot chassis.
A fan module is a customer replaceable unit (CRU) and is hot-
serviceable. Replacing a fan module does not require you to bring the Pilot
oine. The following gure shows the location of the Pilot fan modules.
