T071 - Missing Power Supply
Description GUI Description: A previously installed power supply is missing.
Explanation: The library can no longer detect the presence of a power supply
that was previously physically installed and logically added to the system.
Detection Scenarios Regular polling between LCB and power supply checks for presence of the
power supply.
Root Causes • Power supply has been physically removed after being added to a powered
on system.
• Hardware failure inside supply.
• Hardware failure in library side connector or other electronics.
• Disconnected module terminator or module-to-module cable.
• Damaged module terminator or module-to-module cable with bent or broken
pins.
Service Resolution
Steps
1 Perform DR022 - Resolve Missing Power Supply
on page 377.
2Use the Details option in the RAS ticket to identify which power supply bay
is generating the RAS ticket. Inspect the power supply bay and verify that
there is a power supply present and turned on. For normal operation, both
LEDs (AC OK and DC OK) should be solid green. The STANDBY LED
should be off. Reseat the power supply and swap with others in the unit to
isolate failure to either the slot or the power supply.
3 Inspect the module terminators and module-to-module cables for loose
connectors or damage (bent or broken pins). If damaged, replace the part.
Reseat the terminators and cables.
Possible CRUs/FRUs Note: Read and perform all resolution steps before dispatching any parts.
Dispatch parts as indicated by resolution steps performed above.
• Module Terminators and Module-to-Module Cables
• Power Supply
