C) Mechanical Loading - Prevent unsafe conditions
by avoiding uneven mechanical loading.
D) Circuit Overloading - Consideration should be
given to the connection of the equipment to the
supply circuit and the effect that overloading of
the circuits might have on overcurrent protection
and supply wiring. Appropriate consideration
of equipment power ratings displayed on the
nameplate should be used when addressing this
concern.
E) Earthing - Reliable earthing of rack-mounted
equipment should be maintained. Particular
attention should be given to supply connections
other than direct connections to the power supply
(e.g. use of power strips).

Connecting To The Network
When powering on the device, allow 1 to 2 minutes
for the device to boot up completely before
connecting it to the network. Please refer to the
instructions below for making network connections:
1. Using an Ethernet cable, connect the external
router to the WAN1 port on the firewall. Port 1 is
pre-configured as the WAN1 network segment.
2. (
Optional
) Using an Ethernet cable, connect a
switch to the DMZ port (port 3 on the device).
3. Using an Ethernet cable, connect other Ethernet
devices, such as a switch, to the LAN ports (ports
4, 5, and 6 on the device). These ports are pre-
configured as LAN interfaces by default.
4. Connect a management station to the console
port on the DFL-870 using the included cable to
configure the device using the CLI.
Note
: When connecting a PC to the console port with
the included Mini-USB to USB cable, Windows will
recognize the device and automatically install the
appropriate driver. When using a Linux or MacOS-
based system, you may need manually download
and install the mini-USB drivers. To download these
drivers, visit

is allowed by default. For more information on
configuring connection settings, please refer to the
user manual.
1. Connect the management station to LAN1
(port 4). Make sure that the management
station is configured with a static IP address in
the
192.168.10.2-254
range with a subnet of
255.255.255.0
.
2. Launch one of the compatible web browsers, and
