DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

N/A, the fan module is a hot-swappable CRU

Time Estimate: 30 minutes

Task Complexity: 0

FIELD ENGINEER/CUSTOMER INSTRUCTIONS

PROBLEM OVERVIEW: replace a faulty SPARC T4-4 Server Fan Module

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

The server will continue to operate at full capacity with four or more fan modules installed in the server. The server will not operate with fewer than four fan modules installed and operating. If the server is operating with four fan modules installed and one or more of those four fan modules fails, the server will power down to keep from overheating. You can perform a hot-service on a fan module only if four or more fan modules are operational.

WHAT ACTION DOES THE FIELD ENGINEER/CUSTOMER NEED TO TAKE:

A) Remove a Fan Module

The fan module is a hot-service component that can be replaced by a customer.

1. Locate the faulty fan module that you want to remove from the server. Check the following indicators:

See rear of Server for the locations of the fan modules.

Fan Module LED
System Service Required LEDs on the front panel and rear I/O module
Server Fan Fail LED on the front panel
If the fan fault causes an overtemperature condition to occur, the server Overtemp LED will turn on, and an error message will be logged and displayed on the system console.

2. Determine if you can remove the fan module with the server running or not.
Determine if you can remove a fan module with the server running or if you must shut down the server before removing a fan module.

NOTE - The server will continue to operate at full capacity with four or more fan modules installed in the server. The server will not operate with fewer than four fan modules installed and operating. If the server is operating with four fan modules installed and one or more of those four fan modules fails, the server will power down to keep from overheating. You can perform a hot-service on a fan module only if four or more fan modules are operational.

- If you can remove a fan module with the server running, go to Step 3.

- If you cannot remove a fan module with the server running, remove power From the Server to power down the server before continuing.

3. Press down on the middle portion of the fan lever and lower the lever slightly to disengage the fan latch.

4. Lower the fan lever completely and pull out on the fan module to remove the fan module from the server.

B) Install a Fan Module

1. Insert the fan module into the empty fan module slot.

2. Lift the fan lever up completely until the latch clicks into place to completely seat the fan module into the slot.

3. Power on the server, if necessary.
If you had to power off the server before removing and installing a new fan, return the server to Operation to power on the server again.

4. Verify the fan module functionality.
a. Check the front or rear panel LEDs for the following indications:

Green System OK LED – illuminated

Amber System Fault LED – not illuminated

Amber System Fan Fault LED – not illuminated

See Front Panel System Controls and LEDs and Rear I/O Module LEDs.

Note : If you are replacing a fan module when the server is powered down, the LEDs might stay lit until power is restored to the server and the server can determine that the fan module is functioning properly.

b. Run the ILOM show faulty command to verify that the fault has been cleared.
If the previous steps indicate that no faults have been detected, then the component has been replaced successfully. No further action is required.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Verify functionality, no service LEDs or messages
