ROUBLESHOOTING

This section describes common problems you may encounter and possible

solutions to them. The Barricade can be easily monitored through panel

indicators to identify problems.

Troubleshooting Chart

Symptom

Action

LED Indicators

Power LED is

Off

•

Check connections between the Barricade, the

external power supply, and the wall outlet.

•

If the power indicator does not turn on when the

power cord is plugged in, you may have a problem

with the power outlet, power cord, or external power

supply. However, if the unit powers off after running

for a while, check for loose power connections, power

losses, or surges at the power outlet.

If you still cannot isolate the problem, then the

external power supply may be defective. In this case,

contact Technical Support for assistance.

•

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

•

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.
