DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
Familiarity or training for X4470 platform.

DELIVERY REQUIREMENT: Schedule with maintenance window within contractual terms.

FIELD ENGINEER INSTRUCTIONS

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

Caution 1: If you remove one of the fans in the back row, replace it within 30 seconds to prevent overheating of the server.

Caution 2: Hazardous moving parts. Unless the power to the server is completely shut down, the only service permitted in the fan compartment is the replacement of the fan modules.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Remove a Fan Module

1. Prepare for servicing:

a. Attach an antistatic wrist strap.

b. Extend the server to the maintenance position.

2. Identify the faulty fan module with a corresponding Service Action Required LED.

3. Using your thumb and forefinger, grasp the handle on the fan module and lift it out of the server.

Caution 1: When removing a fan module, do not rock it back and forth. Rocking the fans modules can cause damage to the fan board connectors.

Caution 2: When changing the fan modules, note that only the fan modules can be removed or replaced. Do not service any other components in the fan compartment unless the system is shut down and the power cords are removed.
Install a Fan Module

1. Unpack the replacement fan module and place it on an antistatic mat.
2. Install the replacement fan module into the server.
The fan modules are keyed to ensure that they are installed in the correct orientation.
3. Apply firm pressure to fully seat the fan module.
4. Verify that the Service Action Required LED on the replaced fan module is not lit.
5. Verify that the Top Fan LED and the Service Action Required LED on the front of the server are not lit.

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.
