Known Issue	UPS Family

After updating the NMC’s firmware via a USB flash drive, the USB is not recognized in the display or NMC Web UI.	♦	♦
Some pages in the Web UI help are not updated.	♦	♦
It can take up to 30 minutes to complete a UPS firmware upgrade when using HTTPS. To workaround this, use SCP as an alternative.	♦	♦
When a UPS firmware upgrade is in progress, the upsAdvcontrolFirmwareUpdate SNMP OID incorrectly reports the value as “noFirmwareUpdate” instead of “UpdateinProgress”.	♦	♦
Filtering by time does not work for the Power Event Log.	♦	♦
Entering unsupported commands in the Command Line Interface (CLI) does not return a E102 Parameter error.	♦	♦
The alarm description is shown incorrectly in DCE for outlet group-related alarms.	♦
You cannot unzip the debug file completely from a USB drive. This issue is seen intermittently.	♦
During the Setup Wizard, when selecting output voltage, the UPS may incorrectly indicate the input voltage present causing a warning on the display that can be dismissed.		♦
You are unable to configure some OIDs upsAdvConfigAlarmRedundancy, upsAdvConfigHighBypassLLTransferVolt, and upsAdvConfigLowBypassLLTransferVolt from SNMP interface.		♦
Only alphanumeric passwords are supported for new users created in the NMC for access to the display.		♦
When an internal or external Battery Module is connected or disconnected from its slot, the Event Log entry does not report its serial number.		♦
You cannot make configuration changes via the display when RADIUS is enabled and the User Mode is set to “Authentication Needed”.		♦
The option to cancel or mute a UPS audible alarm is not present in the Web UI.		♦
The ups -s start CLI command is unsuccessful even when the self-test is started correctly.		♦
There is no option to set the language of the display in the NMC Web UI.		♦
There is no option in the Web UI or the display to cancel a UPS audible alarm test. It is not recommended to initiate a continuous alarm as the only way to stop the UPS beeping is to turn off the UPS.		♦
You cannot modify the output voltage setting from the SNMP interface if the output is in Manual Bypass.		♦
The “Minimum Redundancy lost" event is not displayed in PowerChute Network Shutdown although it is supported by the NMC. If this event occurs, the server will not shutdown.		♦
