Environmental and Operating Parameters
The following table lists the key environmental and operating parameters for the DFL-160
hardware.

Heat Flow Considerations
The DFL-160 is a low power device that generates a modest amount of heat output during operation.
The following precautions should be taken to allow this heat to dissipate:
• Do not install the DFL-160 in an environment where the operating ambient temperature might
come close to or go beyond the recommended operating temperature range (as stated in the table
above, the operating range is from 0°C to +50°C).
• Make sure that airflow around the DFL-160 unit is not restricted.
• Do not place anything on top of the unit, including any other electronic devices.
Power Supply Precautions
The following is recommended in regard to the power supply:
• Make sure that any power source circuits are properly grounded, and use the power cord
supplied with the DFL-160 to connect it to the power source.
• Ensure that the DFL-160 does not overload the power circuits, wiring and over-current
protection. To determine the possibility of overloading the supply circuits, add together the
ampere ratings of all devices installed on the same circuit as the DFL-160 and compare the total
with the rating limit for the circuit. The maximum ampere ratings are usually printed on the
devices near AC power connectors.
• If your installation requires any power cords other than the one supplied with the product, be
sure to use a power cord displaying the logo of the safety agency that defines the regulations for
power cords in your country. The logo is your assurance that the power cord can be used safely
with the DFL-160.
• The purchase and use of a separate surge protection unit from a third party should be considered
to protect against damage by electrical power surges. This is particularly recommended in
geographic regions where lightning strikes might occur.
Software Installation
A copy of the NetDefendOS network operating system is already pre-installed on the DFL-160 unit.
When the unit is powered up, NetDefendOS will automatically start for the first time with the
factory default settings. Initial startup is described in Section 2.2, "Web Browser Connection".
