H136268 - BRIDGE CARD EMC SHIELD CAUSES SYSTEM FAILURE
 
 SYMPTOM:
 The PC Server 720 (8642) hangs or fails to boot.
 
 PROBLEM ISOLATION AIDS: NONE
 
 FIX:
 Inspect the EMC shield on the bridge card.  Locate the metal
 clip (one of four) on the component side near capacitor C66.
 If the clip appears too close to capacitor C66, remove the
 EMC shield, and cut out the corner of the metal clip to
 increase the clearance from the capacitor (Recommended).
 -OR-
 Remove the EMC shield, and insulate the edge of the metal clip
 with electrical tape, and re-install the shield (Alternative).

 Some bridge cards were undercut at the EMC shield attach point
 which could cause a short to the C66 capacitor.
