MAP 0460: Scalable Electrical Power Base Unit
– Go to Step 077 on page 1-278 to verify fix.
048
Main power LED card should be replaced; however, this action requires powering off all processor nodes.
Are there other problems requiring this frame to be powered off?
Yes No
049
– Schedule maintenance to replace main power LED card.
– Go to “MAP 0570: End of Call” on page 1-357.
050
– Refer to "Replacing the Main Power Switch or LED" in
IBM RS/6000 SP: Maintenance Information,
Volume 3, Locations and Service Procedures to replace the main power LED card.
– Go to “MAP 0570: End of Call” on page 1-357.
051
System monitor log reports “dc Power Loss” for any power module(s).
Note: Under light power-loading conditions, SEPBU power modules may enable/disable their outputs to
maintain proper output. In this situation, you will see intermittent “dc Power Loss” conditions from
the power modules. If this is a persistent problem, you may choose to put the circuit breaker of
one power module in the Off (‘0’) position.
– From the system monitor on the control workstation, open the “Frame Environment” window.
– Allow the “Frame Environment” window a few minutes to refresh a few times. Correlate this display with
the system monitor log to obtain an accurate condition.
– Check for “dc Power Loss” (red) condition for all power modules.
If all power modules show “dc Power Loss”, then open “Global commands” window and power-off all
processor nodes and/or switch assemblies in this frame.
If only one power module shows “dc Power Loss”, then order another power module for use in
isolating the failing part.
Does the system monitor indicate “dc Power Loss” (red) for any power module(s)?
Yes No
052
No problem detected.
– Go to “MAP 0570: End of Call” on page 1-357.
053
A “dc Power Loss” indicated for one or more power modules.
Are all power modules indicating a “dc Power Loss” condition?
Yes No
054
– Make a note of which power module(s) is indicating a problem.
– Refer to "Removing the SEPBU Power Module" in
IBM RS/6000 SP: Maintenance Information,
Volume 3, Locations and Service Procedures.
