•
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
Cannot Ping the
Barricade 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.
