Troubleshooting

Overview

This chapter covers some common problems that may be encountered while using The Load Balancer and some possible solutions to them. If you follow the suggested steps and The Load Balancer still does not function properly, contact your dealer for further advice.

General Problems

Problem 1:

Solution 1:

Can't connect to The Load Balancer to configure it.

Check the following:

The Load Balancer is properly installed, LAN connections are OK, and it is powered ON.

Ensure that your PC and The Load Balancer are on the same network segment. (If you don't have a router, this must be the case.)

If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it.

If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.1.2 to 192.168.1.254 and thus compatible with The Load Balancer’s default IP Address of 192.168.1.1.

Also, the Network Mask should be set to 255.255.255.0 to match The Load Balancer.

In Windows, you can check these settings by using Control Panel-Networkto check the Properties for the TCP/IP protocol.

Internet Access

Problem 1:

When I enter a URL or IP address I get a time out error.

Solution 1:

A number of things could be causing this. Try the following troubleshooting steps.

 

Check if other PCs work. If they do, ensure that your PCs IP settings are

 

correct. If using a Fixed (Static) IP Address, check the Network Mask, Default

 

gateway and DNS as well as the IP Address.

 

If the PCs are configured correctly, but still not working, check The Load

 

Balancer. Ensure that it is connected and ON. Connect to it and check its

 

settings. (If you can't connect to it, check the LAN and power connections.)

 

If The Load Balancer is configured correctly, check your Internet connection

 

(DSL/Cable modem etc) to see that it is working correctly.

Problem 2:

Some applications do not run properly when using The Load Balancer.
