CAP PROBLEM OVERVIEW:

Centerplane Failure

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

WHAT ACTION DOES ENGINEER NEED TO TAKE:

1. Halt the Solaris operating environment in each domain and power off the system.

2. If you have only one Sun Fire 3800 in a cabinet, or if the Sun Fire 3800 system is a standalone system, remove the power cords from the wall outlets.

3. Disconnect the power cords from the power supplies.

4. Attach a wrist strap or foot strap. Connect the ESD jack from the system to your wrist strap or foot strap. Place a grounded ESD mat close to the system

5. At the front of the system, remove the boards and the I/O assemblies. You do not need to remove the board filler panels, but you do need to remove the I/O assembly filler board.

Note – When you remove the boards and assemblies from the system, do not stack

the boards and assemblies of top of each other.

6. At the front of the system, disconnect the LED cable. The connector key is on the top horizontal surface.

7. At the rear of the system, remove the fan trays and the fan tray filler panel.

a. Loosen the captive screws.

b. Make sure that the power cords to the power supplies are out of the way.

c. Slide the fan trays out.

d. Remove the fan tray filler panel (if installed).

8. Remove the power supplies and power supply filler panels.

You must remove all the power supplies and the filler panels as well.

a. Loosen the captive screws.

b. Holding the power supply handle, slide the power supply partially out of the system.

Caution – Do not remove the power supply completely from the system while

holding the handle of the power supply.

c. Holding the power supply with both hands, slide the power supply completely out of the system.

d. Remove the power supply filler panels.

9. If the Sun Fire 3800 system is installed in a cabinet, remove the clamp

a. Beginning at one end of the clamp, remove the six larger screws with a Phillips screwdriver.

b. Working your way around the clamp, continue to remove all the screws that secure the clamp.

There are two screws on the top and two screws on each of the two sides.

c. Put your fingers in the holes and remove the clamp.

10. Remove the nine smaller screws with a Phillips no. 1 screwdriver.
Make sure that the power supply cables are clear and remove the subchassis.

11. Remove the six screws of the lower bulkhead with a long-shaft Phillips no. 2 screwdriver. Remove the lower bulkhead.

12. Use a long shanked Phillips no. 2 screwdriver to loosen the 18 captive screws on

the bulkhead that attach the centerplane to the system. Loosen the captive screws in this order:

1. Four corners

2. Middle

3. Remaining screws, working your way around the edges

The centerplane hangs on a guide pin and will begin to shift when the last bulkhead screw is unfastened.

13. Disengage the centerplane from the guide pin in the center of the cabinet.

Hold the centerplane, with one hand on the top and one hand on the middle while you

are detaching it from the guide pin. Remove the centerplane.

Now is possible to install the new Centerplane

14. At the rear of the system, install the centerplane.

>a. While holding on to the centerplane at the bottom and the middle, mount the

centerplane to the guide pin in the top center. Hold on to the centerplane while mounting it.

b. Partially tighten the 18 captive screws that attach the centerplane to the system

two or three turns with a Phillips screwdriver, in this order:

1. Upper-left corner

2. Lower-right corner

3. Upper-right corner

4. Lower- left corner

5. Middle screws in this order: (top-middle, left-side middle, right-side middle)

c. Partially tighten the remaining screws, two or three turns with a long handled

Phillips screwdriver, beginning at the lower left of the unit. Continue around the unit from left to right, and partially tighten the screws two or three turns,

ending with the lower right.

Tighten the screws in the same order.

15. Install the lower bulkhead.

a. Partially tighten the six screws, making two or three turns with a Phillips screwdriver, in the following order:

1. Upper-left corner

2. Upper-right corner

3. Lower- left corner

4. Lower-right corner

5. Left middle

6. Right middle

b. Tighten the screws in the same order.

16. Verify that all screws tightened up to this point as specified in these instructions.

17. Slide in the subchassis, making sure that the power supply cables are out of the way.

a. Partially tighten the nine screws, making two or three turns with a Phillips screwdriver in this order:

1. Upper-left

2. Lower-right

3. Lower-left

4. Upper-right

5. Upper-middle screws

6. The remaining screws

b. Tighten the screws in the same order.

18. If you are replacing the Sun Fire 3800 system in a cabinet, install the clamp

There are six screws: two screws on the top and two screws on each of the two sides.

a. Beginning at one end of the clamp, partially tighten the first screw with a Phillips screwdriver.

b. Continuing to work your way around the clamp, partially tighten each screw with a Phillips screwdriver.

c. Tighten the screws in the same order.

19. Install the power supplies and power supply filler panels.

Caution – Do not connect the power supply cables to the power supplies when you install the power supplies. The power must be turned off.

If you are replacing only one power supply, the default positions are at the righthand side. If you are replacing two power supplies, the default positions are the

right and the middle position.

a. Holding the power supply base with both hands, slide the power supply partially in.

b. Holding the power supply handle with both hands, slide the power supply into the system until it is fully engaged.

c. Tighten the two captive screws.

d. Attach the power supply cable.

e. Install the power supply filler panels in the empty power supply slots. Tighten the captive screws.

20. Install the fan trays.
The bottom two fan trays are installed with the captive screws on the top. The top two fan trays are installed with the captive screws on the bottom. The default

configuration is three fan trays installed in this order:

1. Top Left - Filler Panel, FT1

2. Top Right - Fan Tray, FT0

3. Bottom Left - Fan Tray, FT3

4. Bottom Right - Fan Tray, FT2

a. Slide in the bottom two fan trays, FT3 and FT2.

Make sure that the captive screws are on the top.

b. Tighten the two captive screws.

c. Slide in the top two fan trays, FT0 and FT1.

Make sure that the captive screws are on the bottom.

d. Tighten the captive screws.

e. Install the fan tray filler panels to cover the empty fan tray slots.

21. Verify that the captive screws on the power supplies and fan trays are tightened properly.

22. Reconnect the LED cable.
The connector key should go on the top.

Tip – A small flashlight can be useful when you connect the LED cable.

23. At the front of the system, install the boards and assemblies in this order

1. I/O assembly filler board

2. I/O assembly

3. Two system controller boards

4. Lower CPU/Memory board

5. Upper CPU/Memory board

24. Reconnect the cables to the System Controller boards and the I/O assemblies.
