Fan Module Overview

Chapter 4 Installation and Maintenance

Fan Module Overview

Step 8 Ensure that the power supply is properly aligned and the installation screw is tightened.

This completes the steps for reconnecting the DC-input power supply to the SCE 1000 platform.

Fan Module Overview

The fan module provides cooling for the internal components. The fan drawer is a field- replaceable unit containing five fans, and is installed at the right rear of the SCE 1000 platform.

When a fan malfunctions, the fan module should be replaced as promptly as possible. Although it is possible for the unit to function for some time with one non-functioning fan, this is not optimal or recommended.

When a fan failure occurs, the environment monitor will send an error message to the console. An SNMP trap indicating that the fan is not functioning properly is also sent. Note that a fan failure is often audible.

Removing and Replacing the Fan Module

The following sections explain how to remove and replace a fan module in a SCE 1000 platform:

•Removing the Fan Module (on page 4-20 )

•Replacing the Fan Module (on page 4-21)

ESD Warning Do not remove or install modules without using appropriate anti-static guard measures. The SCE 1000 includes an anti-static wrist strap in the accessory kit. Attach the copper tape strap to an unpainted metal surface on the chassis. You may leave the strap connected to the chassis when your have finished.

Removing the Fan Module

Warning When removing the fan drawer, keep hands and fingers away from the spinning fan blades. Let the fan blades stop completely before removing the fan drawer.
