Incorrect handling resulting in damage to system boards (see details below).

Impact

Increasing number of V2x0 system boards are being returned for repair that show signs that they were incorrectly handled resulting in small cracks in and around u13.

Symptoms

System failure or intermittent failure after part swap.

Root Cause

Incorrect handling can cause failure of soldered joints around specific components, thus leading to failure or intermittent failure.

Workaround

When handling the board do so by holding the board with 2 hands, one on either opposite edge. DO NOT hold with one hand.

When removing from the ESD bag support the board from below, by firstly placing your hand in the bag and under the board, remove the board, place on ESD mat on a flat surface, then handle the board by edges or CPU carriers for installation as detailed below.

When replacing the board into the ESD bag reverse the above procedure.

When removing the failed board from the system, disconnect all cabling, remove screws at rear plate on SCSI port and 5mm nuts on Serial management Port. Remove Air Plenum, Fan Assembly, PCI Riser and support. Remove 10 screws retaining System Board to chassis. Stand to the LEFT of the system when viewed from front. Grasp the System Board by the 2 CPU carrier handles and lift board clear.

Installing the board is the reverse of the above.

DO NOT hold board with one hand only.
DO NOT attempt to remove or install board unless held by the CPU carriers.
DO NOT hold board by CPU Heat Sink or Fans

Resolution

The manufacture of the system board has included installation and removal instructions that must be followed when servicing a Sun Fire V2x0 system.
