• Verify that the BARRICADE and attached device are
powered on.
• Be sure the cable is plugged into both the
BARRICADE and the corresponding device.
• Verify that the proper cable type is used and that its
length does not exceed the specified limits.
• Be sure that the network interface on the attached
device is configured for the proper communication
speed and duplex mode.
• Check the adapter on the attached device and cable
connections for possible defects. Replace any
defective adapter or cable if necessary.
Network Connection Problems

from the
attached LAN,
or the
BARRICADE
cannot ping any
device on the
attached LAN
• Verify that the IP addresses are properly configured.
For most applications, you should use the
BARRICADE’s DHCP function to dynamically
assign IP addresses to hosts on the attached LAN.
However, if you manually configure IP addresses on
the LAN, verify that the same network address
(network component of the IP address) and subnet
mask are used for both the BARRICADE and any
attached LAN devices.
• Be sure the device you want to ping (or from which
you are pinging) has been configured for TCP/IP.
