Chapter 38 Troubleshooting Make sure you have entered the user name and password correctly. The user name and password are case-sensitive, so make sure [Caps Lock] is not on. If this does not work, contact the network administrator or local vendor. 38.2 Device Management One device always keeps in On_Pending status in the device window. How can I do? A devices with the On_Pending status means there are some pending tasks the Vantage CNM should set but has not set to the device. If the device keeps in the status for a long time (for example, over 30 minutes), this may cause inconsistency between the Vantage CNM and the device. Try to do the following. 1 Refresh the device window to get the latest device status. Make sure the connection between the device and the Vantage CNM is ok. 2 Make sure the Vantage CNM's public IP address is properly configured. (For example, you can not use 127.0.0.1.). And this IP address should match the one configured in the managed devices. If you need to change the Vantage CNM's public IP address, you have to restart the managed devices or Vantage CNM server to reset the connections. See the procedure to change this IP address in the Section 30.1.1 on page 563. 3 Device firmware backup/restore or configuration file backup/restore on the Vantage CNM has upload/download files on the FTP server. Make sure the FTP server is properly configured, the connection and the FTP account's permission are ok. See Section 30.2 on page 564. 38.3 Device Firmware Management Why do I always fail to upload a firmware file to the Vantage CNM? 606 Vantage CNM User's Guide
