Notes: The green Load2 LED ( 1 ) indicates that power is being supplied to the right pair of ac-power outlets as seen from the rear of the 2145 UPS-1U. The amber Load1 LED ( 2 ) indicates that power is being supplied to the left pair of ac-power outlets as seen from the rear of the 2145 UPS-1U. These outlets are not used by the SAN Volume Controller. This LED might be illuminated during power-on sequences, but it is typically extinguished by the SAN Volume Controller node that is attached to the 2145 UPS-1U. A blank cell indicates that the light or buzzer is off.

Is the power-on indicator for the 2145 UPS-1U that is connected to the failing SAN Volume Controller off?

NO

Go to step 3.

YES

Go to step 2.
(from step 1)
Are other 2145 UPS-1U units showing the power-on indicator as off?
NO

The 2145 UPS-1U might be in standby mode. This can be because the on/off button on this 2145 UPS-1U was pressed, input power has been missing for more than five minutes, or because the SAN Volume Controller shut it down following a reported loss of input power. Press and hold the on/off button until the 2145 UPS-1U power-on indicator is illuminated (approximately five seconds). On some versions of the 2145 UPS-1U, you need a pointed device, such as a screwdriver, to press the on/off button.
Go to step 3.

YES
Either main power is missing from the installation or a redundant ac-power switch has failed. If the 2145 UPS-1U units are connected to a redundant ac-power switch, go to MAP 5320: Redundant ac power. Otherwise, complete these steps:
1. Restore main power to installation.
2. Verify the repair by continuing with MAP 5250: 2145 UPS-1U repair verification.
(from step 1 and step 2)
Are the power-on and load segment 2 indicators for the 2145 UPS-1U illuminated solid green, with service, on-battery, and overload indicators off?
NO

Go to step 4.

YES

The 2145 UPS-1U is no longer showing a fault. Verify the repair by continuing with MAP 5250: 2145 UPS-1U repair verification.
(from step 3)
Is the 2145 UPS-1U on-battery indicator illuminated yellow (solid or flashing), with service and overload indicators off?
NO

Go to step 5.

YES
The input power supply to this 2145 UPS-1U is not working or is not correctly connected, or the 2145 UPS-1U is receiving input power that might be unstable or outside the specified voltage or frequency range. (The voltage should be between 200V and 240V and the frequency should be either 50 Hz or 60 Hz.) The SAN Volume Controller automatically adjusts the 2145 UPS-1U voltage range. If the input voltage has recently changed, the alarm condition might be present until the SAN Volume Controller has adjusted the alarm setting. Power on the SAN Volume Controller that is connected to the 2145 UPS-1U. If the SAN Volume Controller starts the on-battery indicator should go off within five minutes. If the SAN Volume Controller powers off again or if the condition persists for at least five minutes, do the following:
1. Check the input circuit protector on the 2145 UPS-1U rear panel, and press it, if it is open.
2. If redundant ac power is used for the 2145 UPS-1U, check the voltage and frequency at the redundant ac-power switch output receptable connected to this 2145 UPS-1U. If there is no power, go to MAP 5340: Redundant ac power verification. If the power is not within specification, ask the customer to resolve the issue. If redundant ac power is not used for this uninterruptible power supply, check the site power outlet for the 2145 UPS-1U providing power to this SAN Volume Controller. Check the connection, voltage, and frequency. If the power is not within specification, ask the customer to resolve the issue.
3. If the input power is within specification and the input circuit protector is stable, replace the field-replaceable units (FRUs) in the following sequence:
  2145 UPS-1U power cord
  
  2145 UPS-1U
4. Verify the repair by continuing with MAP 5250: 2145 UPS-1U repair verification.
(from step 4)
Is the 2145 UPS-1U overload indicator illuminated solid red?
NO

Go to step 6.

YES
The 2145 UPS-1U output power requirement has exceeded the 2145 UPS-1U capacity.
1. Check that only one SAN Volume Controller node is connected to the 2145 UPS-1U.
2. Check that no other loads are connected to the 2145 UPS-1U.
3. After ensuring that the output loading is correct, turn off the 2145 UPS-1U by pressing the on/off button until the power-on indicator goes off. Then unplug the input power from the 2145 UPS-1U. Wait at least five seconds until all LEDs are off and restart the 2145 UPS-1U by reconnecting it to input power and pressing the on/off button until the 2145 UPS-1U power-on indicator is illuminated (approximately five seconds). On some versions of the 2145 UPS-1U, you need a pointed device, such as a screwdriver, to press the on/off button.
4. If the condition persists, replace the 2145 UPS-1U.
  Note: If the condition recurs, replace the power supply or power supplies in the node. See Replacing the power supply.
5. Verify the repair by continuing with MAP 5250: 2145 UPS-1U repair verification.
(from step 5)
Is the 2145 UPS-1U service indicator illuminated flashing red and the on-battery indicator illuminated solid yellow, with the power-on and overload indicators off?
NO

Go to step 7.

YES
The 2145 UPS-1U battery might be fully discharged or faulty.
1. Check that the 2145 UPS-1U 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 service indicator.
2. If the service indicator is still flashing, replace the 2145 UPS-1U.
3. Verify the repair by continuing with MAP 5250: 2145 UPS-1U repair verification.
(from step 6)
Is the 2145 UPS-1U service indicator illuminated flashing red, the on-battery indicator illuminated solid yellow, and the power-on illuminated solid green, with the overload indicator off?
NO

Go to step 8.

YES
The 2145 UPS-1U internal temperature is too high.
1. Turn off turn off the 2145 UPS-1U by pressing the on/off button until the power-on indicator goes off. Then unplug the 2145 UPS-1U. Clear vents at the front and rear of the 2145 UPS-1U. Remove any heat sources. Ensure the airflow around the 2145 UPS-1U is not restricted.
2. Wait at least five minutes and restart the 2145 UPS-1U by reconnecting to input power and pressing the on/off button until the 2145 UPS-1U power-on indicator is illuminated (approximately five seconds).
3. If the condition persists, replace the 2145 UPS-1U.
4. Verify the repair by continuing with MAP 5250: 2145 UPS-1U repair verification.
(from step 7)
Is the 2145 UPS-1U, service, on-battery, overload, and power-on indicators illuminated and flashing?
NO
The 2145 UPS-1U has an internal fault.
1. Replace the 2145 UPS-1U.
2. Verify the repair by continuing with MAP 5250: 2145 UPS-1U repair verification.
YES
The 2145 UPS-1U battery might be fully discharged or faulty.
1. Check that the 2145 UPS-1U 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 service indicator.
2. If the service indicator is still flashing, replace the 2145 UPS-1U.
3. Verify the repair by continuing with MAP 5250: 2145 UPS-1U repair verification.
