Symptoms

VSM fenced a power supply
Power fault LED is lit
Customer received a SIM message containing FSC7E92 or FSC7E93
If attached to SDP, VSM performed a MIM with FSC7E92 or FSC7E93

Cause

The environmental monitoring task has determined that
the N_INT power supply failure line from the logic card
cage power supply in power zone 0 or 1 is asserted. This
assertion indicates that the power supply is no longer
supplying power to the system.

Solution

Customer: Open a service request in MOS for analyze by Oracle Technical Support.

Please insert the whole SIM message in the description field.

See Doc ID 1452594.1 for SIM message examples.

Two methods to confirm error and generate an ATR to facilitate repair:

METHOD 1
Connect to the VSM and log into the machine.
Navigate to FRU status screen
Examine the status of FRUs CU.1.LPS0 and CU.1.LPS1(card type = LPS2) one should be flagged as fenced.
Make note of the exact FRU location that is fenced and the part number of the FRU.
Create Field Task to have the power supply replaced.
Inform customer that the VSM lost one power supply.
The VSM has a failed power supply however the redundant power supply is functioning and there is no impact to production.

End method 1

METHOD 2
NOTE: IF you do not have access to ZENOBIA use SPLATT to crunch files See KM: 1399676.1
1. Get a full set of base files from the VTSS using standard processes.
2. Place files on zenobia using standard filing conventions.
3. Run the crunch_it all script.
   EX: crunch_it all <enter>
4. Review hic.dmp file
   EX: less hic.dmp <enter>
5. Review hic.dmp file specifically the PSA section.
   You should see a Fencing action against CU.1.LPS0 or LPS1 depending on
   which power supply failed.
   EX: Found PSA Action has taken place
       --------------------------------
       11/09/18 15:06:34 PSA 0x7e93 INIT FENCE 0105 27 - CU.1.LPS1

6. Review crnt_fru.lst file to identify the part number of the defective
   power supply.
7. Create Field Task to have the power supply replaced.
8. Inform customer that the VSM lost one power supply.
   The VSM has a failed power supply however the redundant power supply
   is functioning and there is no impact to production.

End method 2
