Fan Module Overview

The eight fan modules (FMs) are directly accessible at the front of the server and are arranged in two stacked rows of four FMs:

SMOD0 System A: FM 0, 1, 2, 3
SMOD1 System B: FM 4, 5, 6, 7
Bottom row from left to right: FM 0, FM 2, FM 4, and FM 6.
Top row from left to right: FM 1, FM 3, FM 5, and FM 7.

The eight fan modules are installed in two fan frames The left frame contains FM 0, FM1, FM2, and FM 3. The right frame contains FM 4, FM 5, FM 6, and FM 7.

Each vertical pair of FMs provides cooling for the corresponding CPU modules (CMODs), which are located directly behind the FMs. For example, FMs 0 and 1 provide cooling for CMODs 0 and 1, and FMs 6 and 7 provide cooling for CMODs 6 and 7.

How to Remove a Fan Module

Caution - Data Loss. Do not remove more than one fan module from a column while the system is in Main power mode. This action removes power from the CMODs and causes an immediate shutdown. On an eight-CMOD system, this applies to all fan modules. On a four-CMOD system, this applies to the fan modules in the left-side fan frame.

Note - The Fan module is a hot-swap component.

1. Get the new part ready.

a. Obtain box that new part came in.

b. Open box, unwrap the part from any packing material, and lay the new part on an anti-static pad near the server that you are servicing.

2. Identify the fan module by its position and designation or, if it is in a failed state, by its steady on Service Action Required indicator. A fan in a fault state has a lit amber-color Service Action Required indicator.

3. To unlock the fan module, push in the green release button.

4. To remove the fan module, pull it out of the slot

Caution - Electrical hazard. During a hot-service procedure, voltage is present. Do not reach into the vacant fan module slot with your hand or any object. Do not touch the exposed CMOD fan module power connector.

Caution - Server overtemperature. The slot's air vane maintains system cooling by preventing a disruption of server airflow. Do not open the air vane when the system is running.

How to Install a Fan Module

1. Align the fan module with the slot.

2. To install the fan module, slide it into the slot until it stops and gently push it inward until the fan module locks into place. The locking action is accompanied by a click sound.

3. Verify that the green Fan OK indicator on the fan module lights and is on steady.

How to verify the Fan module working properly.

log into ILOM to confirm if Fan module is working properly.

-> show /System/Cooling/Fans/Fan_x

note:the "x" means which Fan Module number your replaced

Sample

-> show /System/Cooling/Fans/Fan_0

/System/Cooling/Fans/Fan_0
    Targets:

    Properties:
        health = OK
        health_details = -
        part_number = Not Supported
        serial_number = Not Supported
        location = FM0 (Fan Module 0)
        fan_percentage = 37 %

Check ILOM event log to see if any errors are related to Fan Module.

faultmgmtsp> fmadm faulty
example

-> start /SP/faultmgmt/shell
Are you sure you want to start /SP/faultmgmt/shell (y/n)? y

faultmgmtsp> fmadm faulty
No faults found

-> show /SP/logs/event/list

Check Solaris FMA info if any errors exist.
