5 The integrated LES/BUS is started. The LEC in the IBM 8285 automatically registers with it.
6 The ports attached the LECs are enabled. They are now ready to connect ATM devices. Note that many LECs should be started after the LES/BUS has been up because they have retry counts which limit how many times they may issue the LANE registration request.
7.2.4 Troubleshooting Your LANE Network
There are relatively few entries in a LANE network that could cause you problems. The following sections describe the typical items that should be considered:

•
Check the Physical (ATM) Connection
Check the LANE Registration
Other Considerations
For more information about troubleshooting your LANE network, refer to the troubleshooting chapter of IBM 8285 Nways ATM Workgroup Switch: Installation and User′s Guide.
7.2.4.1 Check the Physical (ATM) Connection
When you connect an ATM device to the IBM 8285, you have to connect the physical cabling to the device and configure its ATM parameters. Then the device should be connected to the ATM network and you can check the status from the IBM 8285 console using SHOW PORT command.
Figure 45 on page 140 shows a sample console screen when the commands issued.
