Chapter 6. Fans

Before replacing a failed fan in a DE6400 or DE6600 array, review the following

requirements.

• You have a replacement fan that is supported for your controller shelf or drive shelf model.

• You have an ESD wristband, or you have taken other antistatic precautions.



If the Recovery Guru indicates that it is not OK to remove the fan, contact

technical support.

You can replace a fan in a DE6400 or DE6600 array.

About this task

Each DE6400 and DE6600 controller shelf or drive shelf includes five fans. If a fan fails, you must

replace it as soon as possible to ensure that the shelf has adequate cooling.

Before you begin

Make sure you have the following:

• A replacement fan.

• An ESD wristband, or you have taken other antistatic precautions.

• A flat, static free work area.

• Labels to identify each cable that is connected to the controller canister.

• A management station with a browser that can access ThinkSystem System Manager for the

controller. (To open the System Manager interface, point the browser to the controller's domain

name or IP address.)

Place the controller canister offline so you can safely replace the failed fan.

Steps

1. From ThinkSystem System Manager, review the details in the Recovery Guru to confirm that

there is an issue with a fan and to ensure no other items must be addressed first.

2. From the Details area of the Recovery Guru, determine which fan to replace.

3. Back up the storage array's configuration database using ThinkSystem System Manager.
