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.
•
Attach 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 buttons 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 five 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
offline. The
following figure shows a
Controller fan module.
