Key Considerations 809

Potential Hazards The Device Restore and Setup operations initialize most types of device when using Restore prior to applying the software configuration. The initialization of a device and Setup that is connected to your network can cause network loops. It is

particularly likely that a network loop will occur if the target devices are configured with any of the following features prior to the start of the operation:

■VLANs

■Spanning Tree

■Aggregated Links

■Resilient Links

3Com strongly recommends that you isolate target devices from the rest of the network and connect them directly to the management station before using Restore or Setup.

Why Errors can Occur A common reason for the failure of a Device Restore or Setup operation is during Restore and a loss of contact with the target device. This can occur either when the

Setup device is initialized prior to configuration or while the device is being configured. If this happens, please ensure that the target device is either connected directly to the management station or is connected to the management station through a simple unmanaged hub or switch.

If the restored configuration you are applying results in ports being disabled, you will also need to ensure that the device is connected to the management station through a port that does not become disabled when the configuration is applied.
