FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Server X4-2L SAS Expander Assembly needs replacement

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

If the system is still up and functioning, the administrator should perform an orderly and graceful shutdown of applications and OS.  Then power off the server and remove the AC power cords from the system.

A data backup is not a prerequisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.

1. Power off the server and disconnect the power cords from the power supplies.
2. Extend the server to the maintenance position in the rack.
3. Attach an anti-static wrist strap.
4. Remove the top cover.

2. Remove the SAS expander.

1. Disconnect SAS/SATA cables from the SAS expander module making note of their locations so that they may be re-connected in the same positions.
2. To disconnect the HBA cable and the SAS/SATA cables from the SAS expander module, press the latch, and then pull out to disengage each cable from the SAS expander module.
3. To disconnect the SAS/SATA cables from the front storage drive backplane and the SAS expander module, press the latch, and then pull out to disengage the cables from each storage drive backplane.
4. If they are installed disconnect the rear storage drive SAS cables from the SAS expander module, press the latch, and then pull up to disengage the disk drive SAS drive cable from the SAS expander module.
5. Remove the SAS expander module from the chassis:
   1. Locate and loosen the four black push pins that secure the SAS expander module to the server's chassis. Loosen each push pin by pulling up on the pin until it clicks into the open position
   2. Grasp the sides of the SAS expander module, and gently lift the module to disengage the module from the chassis connector
6. Place the SAS expander module aside on an antistatic mat.

3. Replace the SAS expander.

1. Remove the replacement SAS Expander from it's anti-static bag and place on an anti-static mat.
2. Install the SAS expander module:
   1. Lower the SAS expander module into the server chassis, and gently push down on the module to engage the chassis connector.
   2. Push down on the four black push pins to secure the SAS expander module to the server's chassis.
3. Connect the HBA cables and SAS cables to the SAS expander module
4. Route the SAS cables from the disk backplane between the fan modules and between processors and DIMMs in the cable trough.
5. If present Install the cable connectors into the rear-mounted storage drive backplane.To reconnect the rear-mounted storage drive SAS cables to the SAS expander module, plug each cable into its top SAS expander module connector until you hear an audible click.
6. Making sure to reconnect the cables in the same order as they were previously installed reconnect the SAS/SATA cables to the SAS expander module. To reconnect the HBA cable and the SAS/SATA cables to the SAS expander module, plug each cable into its SAS expander module connector until you hear an audible click.
7. To reconnect the front storage drive SAS/SATA cables to the SAS expander module, plug each cable into its SAS expander module connector until you hear and audible click
8. Place the cables into cable tie-downs, and secure them with the tie-downs

4. Return the Server to operation

1. Replace the top cover
2. Remove any anti-static measures that were used.
3. Return the server to it's normal operating position within the rack.
4. Re-install the AC power cords and any data cables that were removed.
5. Power on server. Verify that the Power/OK indicator led lights steady on.
