MAP 0280: 604 or 604e High Node Minimum Configuration
Minimum Configurations for 604 and 604e High Nodes:
Ÿ
Power distribution cable cluster, system planar (SP), I/O planars, I/O card (IOD), CPU module flex
cables, I/O module flex cables, system interface board (SIB), one CPU card (CPU), one memory
card (MC), power supply (PS), lateral planar 1 card, lateral planar 2 card, and node supervisor
assembly.
If no failure is detected, the maintenance menu is displayed. Any other response means one of the
remaining FRUs is failing.

cables, I/O module flex cables, system interface board (SIB), one CPU card (CPU) and one
memory card (MC), power supply (PS), SCSI adapter, lateral planar 1 card, lateral planar 2 card,
and node supervisor assembly.
If no failure is detected, the Diagnostic Operating Instructions frame is displayed when the diagnos-
tics are loaded, and the system console is selected. Any other response means one of the
remaining FRUs is failing.

– Sometimes an SRN or BUMP Error Code will be logged in the BUMP Error Log. Before proceeding,
check the BUMP Error Log for any SRNs or Error Codes. (See "Using the 604 or 604e High Node
BUMP Menus" in
IBM RS/6000 SP: Maintenance Information, Volume 3, Locations and Service Proce-
dures for BUMP menu descriptions.) This is done as follows:
1. Power off
2. From the GUI Node Front Panel Layout, set the physical key to the service position.
3. Press Enter at the TTY console.
4. Type sbb
5. Press Enter
6. Select “Set Flags” (1)
7. Enable the BUMP Console Present Flag, disable the Autoservice IPL flag.
8. To exit, type x twice.
9. Power on
10. When the Maintenance Menu appears, display the BUMP Error Log. (Scan all pages.)
11. If an SRN is logged, record it and any location codes. Location Codes are separated by a blank.
Perform the listed action. An SRN will be preceded by ‘888 103’.
12. If no SRN is logged, check for an Error Code. If an Error Code is logged, record it and any location
code. Location codes are separated by a blank. Perform the listed action. Look up the Error Code
for possible FRUs. See
RS/6000 SP: Maintenance Information, Volume 3.
13. Perform the following:
– Ensure that the diagnostics and the operating system are shut down. At the Maintenance Menu, select
5 and then hit ENTER.
– Ensure that the key position switch is in the Service Position.
– Set the circuit breakers to the On (‘1’) position.
– Ensure power supply cable(s) are connected to power supplies.
– Perform service diagnostics from either hdisk0 or network boot.
– Find the symptom in the following table that best matches the symptom on your system, and then
perform the associated task.
Note: Before verifying any condition indicated in the following steps of this MAP (e.g., a certain code
displayed on the operator panel display), be sure that the system activity has stopped on that
condition (same condition for more than 3 minutes).
