Abstract: SERVER 720 HANGS at CP 69 after PLANAR Replacement
SYMPTOM:
The PC Server 720 (8642) hangs at Check Point 69 (CP 69) during
POST or MicroChannel adapters are not recognized by the system
after the system board FRU P/N 06H1810 has been replaced.
PROBLEM ISOLATION AIDS:
FIX:
If replacing a system board on a Server 720 with MicroChannel
adapter(s), 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.
In the unlikely event that the tiny blue dot is missing and the
Server 720 does not boot properly, order system board FRU P/N 01K7236.
