Troubleshooting
c. Check the 'Desired Power' controls on all FRUs installed on that slot (parent and managed FRUs) and check if the total exceeds the maximum power capability of the slot.
6. If the FRU is in M3, the checks suggested in Step 5 above all pass, and the FRU along with its managed FRUs is below the slot's maximum power capability, it is possible that the Shelf's total power capability is exceeded. In this case, collect all Shelf Manager logs from the /tmp/shmgr/ folder and forward them to Radisys Technical Support for further investigation.
Responding to a FRU not powered properly
Perform the following steps to confirm/correct this indication:
1. Check that the FRU is inserted correctly and that the hot‐swap latch is in the closed position. 2. Check the blue hot‐swap (H/S) LED on the FRU that is not powered correctly. The LED should be blinking with short blinks if it is waiting to be activated by the Shelf Manager. The LED should be off if the Shelf Manager is activating or has already activated the FRU.
a. If the hot‐swap LED remains blinking for a long time, check the hot‐swap state of the FRU. For details, see Overriding the default ShMS hot‐swap mechanism on page 72.
b. If the hot‐swap LED is off, verify the FRU’s voltage sensor readings are within specifications. If they are outside the specifications, remove and re‐insert the FRU.
3. Check that IPMI communications to the FRU are working properly.
4. Use the hotswap CLI command to virtually extract and re‐insert the FRU.
Responding to power LED off in SDP
Indications are that the I/O expander on the SDP that controls the GPOs for the alarm LEDs is getting reset. Other than the Power LED, all other alarm LEDs (including the audible alarms) are periodically updated by the Shelf Manager, so they will all recover to their correct states following that occurrence. However, the Power LED is never touched after ATCA‐5014 IPMC initialization so if it turns off in runtime then it will never get updated again. That is why it remains off.
In newer ATCA‐5014 firmware, an internal state machine constantly monitors the GPOs on the I/O Expander on the SDP and if any are found in an unexpected state such as Power LED off, it is recovered immediately. This kind of local recovery mechanism on the IPMC itself guarantees that the LEDs on the SDP synchronizes with the ATCA‐5014. 119
