Action
• Verify that the Barricade Plus and attached device
are powered on.
• Be sure the cable is plugged into both the Barricade
Plus 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.
• Verify that the IP addresses are properly
configured. For most applications, you should
use the Barricade Plus' DHCP function to
dynamically assign IP addresses to any host on
the attached LAN. However, if you manually
configure any 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 Plus 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.
