Utility power has been restored.
Troubleshooting: No user action is required. This notification is to inform the user that input line voltage to the APC UPS has been restored.
The APC UPS batteries are low and will soon be exhausted if power is not restored.
Troubleshooting: This is a critical condition indicating that the APC UPS has been on battery backup power due to a loss of input line voltage. The user should commence safe system shutdown to prevent a loss of data. This condition can also be prevented by configuring APC's PowerChute plus to perform automatic, unattended shutdown of all attached computers when this condition is reached.
The APC UPS has returned from a low battery condition.
Troubleshooting: No user action is required. This notification is to inform the user that the APC UPS batteries have been charged to a level sufficient to support the protected load if a subsequent power outage occurs.
The APC UPS has switched to battery backup power.
Troubleshooting: The APC UPS has lost input line voltage and is providing battery backup voltage to the loads connected to it. Determine why the voltage has been lost and restore if possible. If the line voltage cannot be restored before battery exhaustion, the user can perform a safe server shutdown and reboot the APC UPS once line voltage is restored. Safe shutdown can be configured for protected system using APC's PowerChute plus software.
The APC UPS batteries are discharged. If power fails, an immediate low battery condition will exist. Sufficient runtime for necessary action cannot be guaranteed.
Troubleshooting: The APC UPS batteries are discharged likely as a result of recent usage during a power failure. The APC UPS used its battery power until a low battery condition was reached. The line voltage has since been restored and the batteries have commenced charging. This trap is only a warning to the user that the APC UPS battery level may not be able support its protected load during a subsequent power outage. The user should allow the battery to recharge (see APC UPS owner's manual for recommended charging time) and check to see if the alarm condition has cleared. If alarm condition still exists, the batteries may need replacement.
Communication lost with external battery pack(s). Check battery signal cable(s).
Troubleshooting: This trap is supported only on APC UPS models that support the addition of external batteries. Check to see that all external battery cables are properly connected. If all cables are connected and the trap has not cleared, it likely means that one or more of the cables is damaged. Disconnect individual cables and verify that the number of batteries decreases. When a cable is disconnected and the number of batteries does not decrease that cable is bad and should be replaced. Contact APC technical support at 800-800-4272 for assistance.
Communication with the APC UPS has been established.
Troubleshooting: No user action is required. This notification is to inform the user that communication between the APC UPS and server has been re-established.
Communication established with external battery pack(s).
Troubleshooting: This trap does not require user action. It is to inform the user that the cable connection to an external battery has been restored.
The APC UPS has sensed a load greater than 100 percent of it's rated capacity.
Troubleshooting: The loads attached to the APC UPS exceeds it's rating. The load level must be reduced by removing one or more devices from the APC UPS output receptacles or by upgrading to a larger APC UPS.
The APC UPS is entering 'sleep' mode.
Troubleshooting: This trap is to inform the user that the APC UPS is going to sleep and will no longer provide output voltage to the connected loads. The APC UPS has either been put to sleep by a management station using an SNMP set or due to a sustained power outage. If the APC UPS has been placed in sleep mode from a management station it can be re-awakened using an SNMP set from the management station. If the condition was caused by a sustained loss of input voltage the APC UPS will automatically recover from this condition shortly after power has been restored. (Automatic wake-up delays can be configured based upon minimum time or battery charge after input line power is restored.)
A contact on the APC Measure-UPS has changed from it's normal position.
Troubleshooting: The user action required will depend on what is connected to the dry contacts. For example, if a door security sensor is connected to a contact and a trap is received indicating that that contact is faulted the user might decide to call security personnel.
A contact on the APC Measure-UPS has returned to it's normal position.
Troubleshooting: A condition which caused a contact fault has been corrected. No user action is required.
The APC UPS failed it's internal self-test.
Troubleshooting: The APC UPS has failed to correctly complete an internal diagnostic. The most likely problem is a battery which has become weak with age and should be replaced. Please refer to the APC UPS documentation for user battery replacement.
The APC UPS is on bypass due to a hardware failure.
Troubleshooting: This trap is presently supported only by the Matrix-UPS and Symmetra Power Array. This trap indicates that the APC UPS has been placed into bypass mode (no electronic line filtering) due to a hardware failure. Check the cooling fans in the APC UPS to ensure they are operational. Call APC technical support at 800-800-4272 for assistance.
The base module bypass power supply needs repair.
Troubleshooting: This trap is presently supported by the Matrix-UPS and Symmetra Power Array. It indicates that the power supply providing voltage to the base module cooling fans has failed. If this condition is not corrected the APC UPS will eventually shut down due to high internal temperatures. APC PowerChute plus installed on the server or workstation can be configured to automatically shutdown the server or workstation connected to the APC UPS when this condition is detected. Call APC technical support at 800-800-4272 for assistance.
The base module fan needs repair.
Troubleshooting: This trap is presently supported by the Matrix-UPS and Symmetra Power Array. This trap indicates that the base fan has failed. Call APC technical support at 800-800-4272 for assistance. If this condition is not corrected the APC UPS will shut down due to a high internal temperature. APC PowerChute plus software installed on the server or workstation can be configured to automatically shutdown the server or workstation connected to the APC UPS when this condition is detected.
The APC UPS passed it's internal self-test.
Troubleshooting: No user action is required. This notification is to inform the user that a diagnostic test has been performed and the APC UPS is working correctly.
The APC UPS has enabled it's Smart-Boost feature.
Troubleshooting: This notification is to inform the user that the input line voltage has dropped below the optimal level. The APC UPS has internally boosted the input voltage to a normal range without utilizing its battery.
A battery run time calibration test has been initiated.
Troubleshooting: This trap is supported only through the PowerNet SNMP hardware Adapter. No user action is required. This trap is notification that a user has initiated a battery calibration from a management station. The calibration allows the APC UPS to calculate an accurate runtime for the attached load.
The batteries in the APC UPS need to be replaced.
Troubleshooting: The batteries in the APC UPS have been found to be bad by internal diagnostic tests and will not be able to support the protected load during a power outage. Refer to the APC UPS battery replacement procedure in the APC UPS Owner's Manual.
APC UPS put on bypass by user via software or front panel.
Troubleshooting: No user action is required. This trap is a notification that a user has placed the APC UPS into bypass mode using an SNMP set from a management station or from the front panel.
APC UPS put on bypass by user via rear switch.
Troubleshooting: No user action is required. This trap is a notification that the APC UPS has been placed into bypass mode due to someone changing the position of the Bypass switch on the back of the Matrix-UPS or lower front of the Symmetra Power Array.
The APC UPS has returned from bypass mode.
Troubleshooting: No user action is required. The trap is a notification that the APC UPS has been restored to normal operation and is no longer bypassing the electronics unit.
Communication with the APC UPS has been lost.
Troubleshooting: This trap indicates that communication between the software agent and APC UPS has been lost. Determine if the serial cable (black 24C cable) is disconnected between the server and APC UPS. If the serial cable is connected ensure UPS.exe is running.
