|
| 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. | ♦ | ♦ |
| 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. | ♦ | |
| 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. | ♦ | |
| You are unable to configure upsAdvConfigAlarmRedundancy OID from SNMP interface. | ♦ | |
| 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. | ♦ | |
