Please see the LEGAL - Trademark notice.
It is a REQUIREMENT that ECA013 is
applied to the Server - PRIOR to applying this TIP.
---------------------------------------------------------
Follow this procedure to put the processors back on-line:
1. Boot to the Setup utility by pressing <F1> during the memory count.
2. Load Setup Defaults by pressing <F5> <Enter>.
3. Save and Exit by pressing <F10> <Enter>.
-OR-
Reset NVRAM (CMOS) with switch S6A1-1. Refer to the procedure
(on pages 109-110 in the PC Server 704 HMM, publication number
S78H-6414-00.)
4. Power off the Server
5. Disconnect the I2C cable FRU P/N 75H9051 from connector J10
on the power distribution board.
6. Restart the Server.
This action resets system register settings to their default values.
If the errors continue after restoring the system defaults,
and after disconnecting the I2C cable
continue with normal problem determination procedures.
NOTE:
With the I2C cable disconnected, the System Drive-fault LED will
be disabled, but the individual Hard Disk Fault LEDs will
function normally.
