Part

Part No: 501-7288-06
Part Description: FRU, MBC Board

Impact

The first set of 105 FRU MBC boards for the Sun Fire V445 were shipped from CTH with the jumper for pins 1 and 2 of J0601 installed. These FRUs will fail to operate with J0601 in this position and the system will not power up. The jumper must be moved to pin 2 only (open) for the module to operate correctly.

Contributing Factors

A specific group of MBC Board FRUs, P/N 501-7288-06, are affected. The boards can be identified by visually inspecting for pins 1 and 2 of J0601 being jumpered. In addition, they will have serial numbers (at top left of board) from the following list.

Symptoms

When an affected MBC FRU is installed the system will not power up.

Root Cause

Only the lower segments of ALOM code was loaded into ALOM flashrom on these 105 MBCs. After BFT testing the jumper was installed across pins 1 and 2 but the boards were not retested. With this jumper installed, the MBC card will flip upper and lower code and try to execute non-executable code.

Resolution

When replacing the MBC board from FRU stock, move the jumper to pin 2(J0601) prior to replacing the MBC board, then update the ALOM firmware.

Detailed Procedure:

1. Visually inspect the MBC board prior to installation.
2. Refer to the attached document for pin position.
3. Move the jumper to pin 2 (OPEN).
4. Install the MBC board into the system.
5. Update the ALOM firmware. From the "sc>" prompt:

  sc> flashupdate -s (netid) -f (file of download firmware)
  sc> resetsc -y

6. Power on the system

The latest ALOM firmware may be downloaded from http://www.sun.com/download/products.xml?id=44eb1efd

29-sep-2006 karen continuing this FAB in pete's absence. His last question was :
MGT, MBC, and CTH don't appear to be tests. The only one I am really concerned about is MBC since that is the affected component. What is the full name of this board that will be displayed in the Sun System Handbook?
