MAP 0370: Main Power
Common to PDU and SEPBU:
Ÿ Provides supe12 V dc power
Ÿ Pr48 V dc power for processor node(s) and/or switch assemblies (usually N+1 configura-
tion)
Ÿ
Houses frame supervisor for frame control/monitoring
Ÿ
Common connectors at bulkhead
Ÿ The +48 V dc power can be controlled via frame supervisor.
DANGER
Both the SEPBU power chassis and the PDU 48 V power chassis are field replaceable units
(FRUs) which contain NO serviceable parts; they are labeled as such. Do not attempt to
isolate or repair these components, since doing so may result in severe injury or even
death.
001
Problem detected concerning power in frame.
Attention: When servicing frame(s) in a parallel environment, powering off a frame will cause all parallel
jobs to terminate. The switch network can not be re-initialized until power is restored to the frame, or the
frame is removed from the active configuration in a multi-frame system. Refer to "Removing and Restoring
Switch Resources" in
IBM RS/6000 SP: Maintenance Information, Volume 3, Locations and Service Proce-
dures, for these procedures.
Note: PDU is an acronym for Power Distribution Unit. SEPBU is an acronym for Scalable Electrical
Power Base Unit.
