Restricting hosts that can change
product settings
The product is equipped with the password function and host restricting function to ensure security of
the product itself. Using these functions enables you to prevent third parties from changing a product
setting without permission. The product can be accessed by means of the Web browser (HTTP),
TELNET, SSH, or SFTP software. You can configure the restriction individually for each of them.
