REFERENCE INFORMATION:

Servicing Fan Modules

The following topics are covered in this section:

About System Fans

Each server node contains two fan modules. Each fan module contains a single, dual-motor, 80 mm, counter-rotating fan assembly that contains two fans. Each fan module is hot-swappable.

When a server node is removed from the system, the fans provide sufficient cooling for all 24 front disks and the server node. A door automatically closes off the vacant server node slot to ensure proper cooling. When the server node is replaced, its two fans also cool the 24 front disks and provide cooling to the second server node.

Caution - While the fan modules do provide some cooling redundancy, if a fan module fails, replace it as soon as possible.

Fan Module LED Reference

Each fan module contains a single, bicolored LED that indicates fan fault status. This LED is visible from the rear of the server node. For a description of the fan LEDs, see Server Node Fan LEDs.

See Server Node General Status Indicators for more information about system status LEDs.

Detecting Fan Module Failure

The following LEDs are lit when a fan module fault is detected:

Front and rear Service Required LEDs located on each server node
REAR HDD/PS/FAN LED located on the front of each server node
Fan Fault Status LED located on the faulty fan module

The system Overtemperature LED for a server node might light if a fan fault causes an increase in server node operating temperature. See Server Node General Status Indicators for more information about server node LEDs.

Remove Fan Module (CRU)

Identify the faulty fan module with its amber LED.
A Fan Fault Status LED is located on each fan module as shown in the previous figure. When a fan fails, the LED lights amber, indicating that service is required.
To remove the faulty fan module, press down on the fan release lever [1].
While holding the release lever down, use the handle on the fan module to pull it out of the server node [2].
The fan door swings shut to ensure proper cooling.

Install Fan Module (CRU)

Align the fan module in the fan door and slide it into the server node.
The extender on the side of the fan module pushes the fan door open, allowing the fan module to enter.
Apply firm pressure to fully seat the fan module.
The fan release lever engages when the fan is fully seated.
Verify that the Fan Fault Status LED on the replacement fan module is lit green.
Verify that the following fault LEDs on the applicable server node are off.
- Front and rear Service Required LEDs located on the applicable server node
- REAR HDD/PS/FAN LED located on the front of the applicable server node
See Server Node General Status Indicators for more information about system LEDs.

Note: After the fan replacement, if the Service Processor is still reporting a fan failure/missing. Then the issue could be the fan power cable inside the System Controller. The node must be brought down in order to investigate this cable. Refer to "Servicing the Fan Power Cables" section in the Service Manual:
