Management Problems
Cannot connect 
using the web 
browser• Be sure to have configured the Barricade with a valid 
IP address, subnet mask, and default gateway.
• Check that you have a valid network connection to the 
Barricade and that the port you are using has not been 
disabled.
• Check the network cabling between the management 
station and the Barricade.
Forgot or lost 
the password• Press the Reset button on the rear panel (holding it 
down for at least six seconds) to restore the factory 
defaults. Troubleshooting Chart

Wireless Problems
A wireless PC 
cannot associate 
with the 
Barricade.• Make sure the wireless PC has the same SSID settings 
as the Barricade. See “Channel and SSID” on page 25.
• You need to have the same security settings on the 
clients and the Barricade. See “Security” on page 27.
The wireless 
network is often 
interrupted.• Move your wireless PC closer to the Barricade to find 
a better signal. If the signal is still weak, change the 
angle of the antenna.
• There may be interference, possibly caused by 
microwave ovens or wireless phones. Change the 
location of the possible sources of interference or 
change the location of the Barricade.
• Change the wireless channel on the Barricade. See 
“Channel and SSID” on page 25.
• Check that the antenna, connectors, and cabling are 
firmly connected.
The Barricade 
cannot be 
detected by a 
wireless client.• The distance between the Barricade and wireless PC is 
too great.
• Make sure the wireless PC has the same SSID and 
security settings as the Barricade. See “Channel and 
SSID” on page 25 and “Security” on page 27. Troubleshooting Chart

Ethernet Cable
Caution:Do not plug a phone jack connector into an RJ-45 port. For 
Ethernet connections, use only twisted-pair cables with RJ-45 
connectors that conform to FCC standards.
Specifications
Wiring Conventions
For Ethernet connections, a twisted-pair cable must have two pairs of 
wires. Each wire pair is identified by two different colors. For example, one 
wire might be red and the other, red with white stripes. Also, an RJ-45 
connector must be attached to both ends of the cable.
Cable Types and Specifications
Cable Type Max. Length Connector
10BASE-T Cat. 3, 4, 5 100-ohm UTP 100 m (328 ft) RJ-45
100BASE-TX Cat. 5 100-ohm UTP 100 m (328 ft) RJ-45 
						

							CABLES
B-2
Each wire pair must be attached to the RJ-45 connectors in a specific 
orientation. The following figure illustrates how the pins on an Ethernet 
RJ-45 connector are numbered. Be sure to hold the connectors in the same 
orientation when attaching the wires to the pins. 
Figure B-1.  RJ-45 Ethernet Connector Pin Numbers
RJ-45 Port Ethernet Connection
Use the straight-through CAT -5 Ethernet cable provided in the package 
to connect the Barricade to your PC. When connecting to other network 
devices such as an Ethernet switch, use the cable type shown in the 
following table.

Pin Assignments
With 10BASE-T/100BASE-TX cable, pins 1 and 2 are used for 
transmitting data, and pins 3 and 6 for receiving data.
Straight-Through Wiring
If the port on the attached device has internal crossover wiring (MDI-X), 
then use straight-through cable.
