Setting the Waiting Time for Connection at Startup
If you connect the machine to a switching hub, it may not be able to connect to a network even though your network settings are set correctly. This occurs because the spanning tree process performed between switching hubs prevents them from communicating with each other immediately after the machine connects to a switching hub.
In this case, use the following procedure to delay the start of communication.
