AMBTEMP

A processor (critical/warning) over-temperature fault occurred.

Before you begin

Note: Storage complex repair actions must always be managed from the management console. To replace any FRUs identified in this procedure, use Storage Facility Management > storage facility > Exchange Parts. If the FRUs are listed in this or another Serviceable Event, select them from there.

Procedure

  1. Is the room ambient temperature within normal range (less than 35 degrees C or 95 degrees F)?
    • Yes, go to step 3.
    • No, go to the next step.
  2. Do the following:
    1. Notify the customer. The customer must bring the room temperature within normal range.
    2. For more information about over-temperature conditions including proper installation of the storage facility, refer to MAP20E0 Rack temperature alert and the Installation and Planning Guide PDF included on the service documentation CD that should be stored in the document enclosure at the front upper left of rack-1.
    3. Display open serviceable events looking for related over-temperature problems and review them.
    4. After the customer has restored the proper ambient room temperature, cancel all related over-temperature serviceable events.
    5. If the storage facility is powered off, you will need to manually power it back on using the management console. Refer to MAP2470 Powering off and on the storage facility from the management console.
    6. If the storage facility has problems powering on, look for new related open serviceable events or use visual symptoms to begin the repair. If none exist, call the next level of support.
    7. Exit this procedure.
  3. There can be other conditions that cause an over-temperature to be reported by multiple resources in this storage facility. Read the following substeps before continuing.
    1. An over-temperature may affect one CEC enclosure or may affect the entire rack. If it affects the rack, there should be other related open serviceable events.
    2. Before continuing, read MAP20E0 Rack temperature alert.
    3. If other related problems are found, repair those first.
    4. If no other problems are found, return here and continue with the next step. The next steps assume the problem only affects this CEC enclosure.
  4. Are the front and rear of the CEC enclosure free of obstructions?
    • Yes, continue with the next step.
    • No, the CEC enclosure must be free of obstructions for proper air flow.
  5. At the front left of the CEC enclosure, do all the positions in the system processor backplane have cards or fillers to ensure the air flow is correct?
    • Yes, continue with the next step.
    • No, fill any open positions with the proper parts. Retry the procedure that failed. This ends the procedure.
  6. At the right rear of the CEC enclosure, are both power supplies installed?
    • Yes, continue with the next step.
    • No, install the missing power supply. Retry the procedure that failed. This ends the procedure.
  7. Exchange the following field replaceable units (FRUs), if present, one at a time. See Location codes in serviceable events and Exchanging parts.
    • Processor 1, at location P2–C1
    • Processor 2, at location P2–C2
  8. After each FRU is exchanged, is the error code that sent you to this procedure still reported?
    • Yes, replace the next FRU on the list. If all FRUs on the list have been replaced, call your next level of support. This ends the procedure.
    • No, the problem has been corrected. Return to the procedure that sent you here. This ends the procedure.
