ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

PROBLEM OVERVIEW: Netra SPARC S7-2 LED Board Replacement

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

DAMAGE ALERT: Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc). If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return FRU just as the new FRU was packaged, to avoid any damages during shipping.

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

Customer should perform an orderly and graceful shutdown of applications and OS to get the OpenBoot PROM prompt. Then power off the server and remove the AC power cords from the system.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Remove LED Board

1. Prepare the server for service.

a. Power off the server and disconnect the power cords from the power supplies.
b. Extend the server to the maintenance position in the rack.
c. Attach an antistatic wrist strap to your wrist and then to a metal area on the chassis.

Caution - Components inside the chassis might be hot. Use caution when servicing components inside the chassis.

2. Remove server top cover:

a. Open the server top cover by pressing and holding down the top cover release button and then use the recessed area to slide the top cover toward the rear of the server (about 0.5 inches (12.7 mm)).
b. Lift the top cover off the chassis and set it aside.

3. Open the front bezel.

4. Remove all Fan Modules.

5. Remove the Fan Tray.

6. Disconnect the disk backplane cables & rotate the Drive Cage to the service position.

7. Remove the USB cable from the PSU duct's channel & then remove the PSU duct.

8. Loosen the cables from the main air duct assembly.

9. Loosen the left thumb screw bracket, slide it forward to remove, & then remove the air duct.

10. Remove the cables from the cable tie to allow access to the LED board's connector on the motherboard.

11. Disconnect the LED Board cable from the motherboard.

12. Remove the left LED indicator module:

a. Remove the two No. 2 Phillips screws that secure the LED indicator module to the server front panel.
b. Remove the LED indicator module from the server front panel.

Install Left LED Indicator Module

1. Position the LED on the server front panel.

2. Insert and tighten the two No. 2 Phillips screws to secure the LED indicator module to the server front panel.

3. Reconnect the LED board cable to the motherboard.

10. Install the fan tray

11. Install all fan modules

12. Close the front bezel.

13. Install the server top cover. Place the server top cover on the chassis and slide the top cover toward the front of the server (about 0.5 inches (12.7 mm)) until you hear the top cover release button lock into place.

14. Return the Server to operation.

a. Remove any anti-static measures that were used.
b. Return the server to it's normal operating position within the rack.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FE/CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot system and monitor boot sequence for errors. Test functionality of system:
1. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command to verify that the fault has been cleared.
2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear
