2.11 IT security
Ensure that the LP4502 is installed securely. Create user accounts to the web configuration page using
secure passwords.
Ensure all DIP switches are to be in the
OFF
position for the normal operating mode.
The LP4502 is shipped from the factory with a default login account, which is enabled when DIP 1 is moved
from
OFF
to
ON
). The default login user name (admin) and password (password) will be
available for five minutes once the DIP switch is toggled. It is therefore important that at least one user
account is defined, and the DIP switches are set to
OFF
before the LP4502 is commissioned.
Configuring the LP4502 with an IP address that is accessible from the public is
not
recommended.
The following options are available for enhanced network security:
n
Disable SNMP.
n
Zeroconf discovery.
n
The web configuration module.
n
Enable data encryption over the host communication port.
