Replace a Controller Fan Module
If a fan module fails, the system issues critical alerts. Replace failed fan modules
as soon as possible.
Prerequisites:
•
Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch
shaft.
• 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.
• Deploy any rack anti-tilt mechanism before releasing the release buons and
extending the Controller chassis.
• Fail over the Controller before replacing the component using Guided
Maintenance.
Note: The Controller must be failed over to prevent data loss or data
corruption during the component replacement process.
• Initiate Guided Maintenance only when you are able to replace the fan
module immediately.
Each Controller has v
e fan modules that are located side-by-side at the center
inside the Controller chassis. A fan module is a customer replaceable unit (CRU).
Replacing a fan module requires you to bring the Controller oine. The
following gure shows a Controller fan module.
