A-1 APPENDIX A TROUBLESHOOTING 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.
TROUBLESHOOTING A-2 LED Indicators LAN 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 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 h o s t s o n t h e a t t a c h e d L A N . H o w e v e r , i f y o u m a n u a l l y 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.

TROUBLESHOOTING A-3 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 Symptom Action
TROUBLESHOOTING A-4 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 4-26. • You need to have the same security settings on the clients and the Barricade. See “Security” on page 4-29. WEP encryption not working when using Windows Zero Configuration (WZC) serviceIf you are using WEP encryption on the SMC Barricade and Windows Zero Configuration (WZC) service to configure the wireless settings on your PC you may experience problems connecting to the SMC Barricade. This is caused by a conflict with beacon packet element ID 221 used by the WPS protocol and Windows Zero Configuration (WZC) service. There are four different ways you can easily solve this problem. Take any one of the following actions: 1. Update WZC. Please visit Microsoft download center for upgrading the WZC: Wireless LAN API (KB918997) at http://www.microsoft.com/downloads/details.aspx?Fa milyID=52a43bab-dc4e-413f-ac71- 158efd1ada50&DisplayLang=en 2. Disable WPS. Check Disabled and click Apply Changes on Wi-Fi Protected Setup (WPS) screen. See “Wi-Fi Protected Setup (WPS)” on page 4-36 for details. 3. Use WPA/WPA2-PSK. See “WPA” on page 4-31, “WPA2” on page 4-32 for configuring WPA/WPA2-PSK security. 4. Manually configure profile using WZC. Disable the security authentication manually. - Click on Wireless Network Connection/change advanced settings of the client PC. - Click on the Wireless Networks, choose the appropriate wireless network name, and click Properties. - Click Authentication and uncheck the Enable IEEE 802.1X authentication for this network. - Click OK to finish configuration.

TROUBLESHOOTING A-5 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 4-26. • 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 4-26 and “Security” on page 4-29. Troubleshooting Chart Symptom Action
B-1 APPENDIX B CABLES RJ-45 Cable Caution:DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with 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 Connection Use the straight-through CAT-5 Ethernet cable provided in the package to connect the Router to your PC. When connecting to other network devices such as an Ethernet switch, use the cable type shown in the following table.
