Refer to Table 18, Table 19, Table 20, Table 21, and Table 22, when experiencing system shutdown related to voltage or temperature problems.
Table 18 describes voltage related system shutdowns, their meanings,
and suggested actions.
Table 18. Voltage related shutdown messages and actions
Message | Meaning | Suggested Action |
---|---|---|
System shutoff due to X current over max value | Level-critical; system drawing too much current on voltage X bus | See "Power checkout". |
System shutoff due to X current over min value | Level-critical; current on voltage bus X under minimum value | See "Power checkout". |
System shutoff due to X V over voltage | Level-critical; system shutoff due to X supply over voltage |
|
System shutoff due to X V under voltage | Level-critical system shutoff due to X supply under voltage |
|
System shutoff due to VRM X over voltage |
|
|
Table 19 describes temperature-related shutdown messages and
suggested actions.
Table 19. Temperature related shutdown messages and suggested actions
Message | Meaning | Suggested Action |
---|---|---|
System shutoff due to board over temperature | Level-critical; board is over temperature |
|
System shutoff due to CPU X over temperature | Level-critical; CPU X is over temperature |
|
System shutoff due to CPU X under temperature | Level-critical; CPU X is under temperature | Ambient temperature must be within normal operating specifications; see Appendix E, "Specifications". |
System shutoff due to DASD temperature (sensor X) | Level-critical; DASD area reported temperature outside recommended operating range | Ensure system is being properly cooled, see Appendix E, "Specifications". |
System shutoff due to high ambient temperature | Level-critical; high ambient temperature | Ambient temperature must be within normal operating specifications; see Appendix E, "Specifications". |
System shutoff due to system board under temperature | Level-critical; system board is under temperature | Ambient temperature must be within normal operating specifications; see Appendix E, "Specifications". |
