  1. Is the mode indicator for the 2145 UPS that is connected to the failing SAN Volume Controller 2145-4F2 off?
    NO
    Go to step 3.
    YES
    Go to step 2.
  2. (from step 1)
    Are other 2145 UPS units showing the mode indicator off?
    NO
    The power supply to this 2145 UPS is faulty or not connected correctly.
    1. Ask the customer to check the site power connection to this 2145 UPS.
    2. If the input power connection is stable, replace the field-replaceable units (FRUs) in the following sequence:
      1. 2145 UPS power cord
      2. 2145 UPS electronics assembly
      3. 2145 UPS assembly
    3. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
    YES
    Main power is missing from installation.
    1. Restore main power to installation.
    2. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
  3. (from step 1)
    Is the 2145 UPS mode indicator illuminated and flashing green?
    NO
    Go to step 4.
    YES
    The 2145 UPS is in standby mode. This can be because the SAN Volume Controller 2145-4F2 nodes powered by this 2145 UPS have been turned off for more than five minutes, or the off button on this 2145 UPS was pressed.
    1. Press and hold the on button until you hear the 2145 UPS beep (approximately one second) and the power-on indicator shows solid green. If the mode indicator does not change to solid green, replace the 2145 UPS electronics assembly.
    2. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
  4. (from step 3)
    Is the mode indicator illuminated solid red?
    NO
    Go to step 8.
    YES
    The 2145 UPS is in bypass mode. Go to step 5
  5. (from step 4)
    Is the 2145 UPS overload load level indicator illuminated red?
    NO
    Go to step 6.
    YES
    The 2145 UPS output power requirement exceeded the 2145 UPS capacity.
    1. Check that no more than two SAN Volume Controller 2145-4F2 nodes are connected to the 2145 UPS.
    2. Check that only SAN Volume Controller 2145-4F2 nodes are connected to the 2145 UPS.
    3. After ensuring output loading is correct, turn off and unplug the input power from the 2145 UPS. Wait at least five seconds until all LEDs are off and restart the 2145 UPS by reconnecting to input power and pressing the on button until you hear the 2145 UPS beep (approximately one second).
    4. If the condition persists, call the IBM® Support Center.
    5. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
  6. (from step 5)
    Is the 2145 UPS general alarm indicator illuminated and flashing red (causing a continuous audible alarm)?
    NO
    Go to step 7.
    YES
    The 2145 UPS internal temperature is too high.
    1. Turn off and unplug the 2145 UPS. Clear the vents at the front and rear of the 2145 UPS. Remove any heat sources. Ensure the airflow around the 2145 UPS is not restricted.
    2. Wait at least five minutes and restart the 2145 UPS by reconnecting to input power and pressing the on button until you hear the 2145 UPS beep (approximately one second).
    3. If the condition persists, replace the 2145 UPS electronics assembly.
    4. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
  7. (from step 6)
    Is the 2145 UPS Battery Mode indicator illuminated and flashing red (causing an audible beep every five seconds)?
    NO
    The 2145 UPS is in bypass mode because of an internal 2145 UPS fault.
    1. Replace the following assemblies in turn:
      • 2145 UPS electronics assembly
      • 2145 UPS battery assembly
      • 2145 UPS assembly
    2. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
    YES
    The 2145 UPS battery might be fully discharged or not connected correctly.
    1. Check that the 2145 UPS battery assembly is installed correctly.
    2. Check that the 2145 UPS has been connected to a power outlet for at least two hours to charge the battery. After charging the battery, press and hold the test/alarm reset button for three seconds; and then check the battery mode indicator.
    3. If the battery mode indicator is still on, replace the 2145 UPS battery assembly.
    4. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
  8. (from step 4
    Is the 2145 UPS wiring fault indicator illuminated and flashing red (causing an audible beep every five seconds)?
    NO
    Go to step 9.
    YES
    The 2145 UPS ground wire connection does not exist or the power input line and neutral wires are reversed.
    1. Check the grounding of the 2145 UPS.
    2. Ask the customer to check the 2145 UPS input power connection.
    3. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
  9. (from step 8)

    Is the 2145 UPS mode indicator flashing red (causing an audible beep every five seconds)?

    NO
    Go to step 10.
    YES
    The 2145 UPS is receiving input power that might be unstable or outside the specified voltage or frequency range. The SAN Volume Controller 2145-4F2 automatically adjusts the 2145 UPS voltage range. If the input voltage has recently changed, the alarm condition might be present until the SAN Volume Controller 2145-4F2 has adjusted the alarm setting. Ensure that an operational SAN Volume Controller 2145-4F2 is connected to the 2145 UPS. If the condition persists for at least five minutes, do the following:
    1. Ask the customer to check the site power for the 2145 UPS that is providing power to this SAN Volume Controller 2145-4F2. Check the connection, voltage, and frequency.
    2. If input power is available, replace the 2145 UPS electronics assembly.
    3. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
  10. (from step 9)
    Are the 2145 UPS general alarm, battery power, battery mode, wiring fault, and mode indicators illuminated and flashing red (causing a continuous audible alarm)?
    NO
    The 2145 UPS is no longer showing a fault. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification.
    YES
    The 2145 UPS is reporting a fault condition.
    1. Replace the following assemblies in turn:
      • 2145 UPS electronics assembly
      • 2145 UPS battery assembly
      • 2145 UPS assembly
    2. Verify the repair by continuing with MAP 5300: 2145 UPS repair verification2145 UPS.
