WARNING! Improper shutdown of the modem may result in the underlying cellular module becoming irrecoverably unresponsive. Digi strongly recommends performing a clean shutdown procedure on your XBee cellular devices before removing power from the devices. Performing a shutdown allows the module to unregister from the cellular network and safely store operating parameters.

The RSA PKCS#1 format is the only common format across XBee Cellular device variants. You can identify a PKCS#1 key file by the presence of BEGIN RSA PRIVATE KEY in the file header.

The XBee devices that have the x11 or later version of the firmware installed are by default able to secure the TLS connection to Digi Remote Manager. The default configuration provides confidentiality of the communication but is not able to authenticate the server without a certificate being provided.
