Link LED is OFF • 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

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
clients on the 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 the LAN devices.
• Be sure the device you want to Ping (and the device
from which you are Pinging) have been configured for
TCP/IP.
