H136842 - SERVER 720 HANGS AT CP 69 AFTER PLANAR REPLACEMENT SYMPTOM: The PC Server 720 (8642) hangs at Check Point 69 (CP 69) during POST after the system board FRU p/n06H1810 has been replaced. PROBLEM ISOLATION AIDS: - The Server 720 has a MicroChannel RAID adapter FRU p/n06H3059 FIX: If installing a system board on a Server 720 with a MicroChannel RAID adapter, inspect the system board first: Locate the small chip at U74 and look for a tiny blue dot the size of a period (.). If this chip has a blue dot, the system board is good and can be installed. -OR- If ordering a system board for a Server 720 configured with a MicroChannel RAID adapter, contact Brian Rousey at: tie-line 793-8203, 512-823-8203 (work) or 512-869-2603 (home) and Brian will ship a new system board. The current field stock of system boards will work with all other Server 720 SCSI and RAID configurations. .-------------------------------------------------------. | ========================== | | ==================== | | ========================== | | ==================== | | _ ========================== | -------- |_| U74 ==================== | | ========================== | | ==================== | | ============================== | | ==================== | | ========================== | | ==================== | | ========================== | | ==================== | | | | ============================== ==================== | | ============================== | | | | ============================== | | | | | | ========================== | | ========================== | | ========================== | | ========================== | | ========================== | | ========================== | ---------------------------------------------------------------- The affected stock is being cleared from the field and this tip will be updated when the good stock is available.
