			OFF	DIP switch settings

*Use the SHOW DEVICE command to view the DIP configuration setting. Use the SET DEVICE DIP_CONFIGURATION command to change the DIP configuration setting.

†If the carrier does not have configuration settings stored in NVRAM, it uses default settings.

If the DMM detects a problem with the NVRAM configuration, it forces the carrier to use default settings. For example, if you install the carrier with ports assigned to Ethernet_8 into an ONcore hub model that does not support Ethernet_8. If the configuration problem is port level, the DMM forces only the affected ports to use default settings.

‡ The DMM must be fully initialized when you install the carrier module.

Selecting a Network The Edge Router engine connects to an Ethernet network through a backplane port on the ONcore carrier. A base engine installed in ONcore carrier engine bay 1 uses carrier backplane port 1. A base engine installed in ONcore carrier engine bay 2 uses carrier backplane port 5.

You can assign a carrier backplane port to:

■One of eight Ethernet backplane networks

■One of four Isolated backplane networks

For details on backplane networks, refer to the ONcore Switching Hub Installation and Operation Guide (Document Number 17-00362-5).
