10/100Base-T Ethernet Interface

The Ethernet port (ETH 0/1) is an RJ-45 connector. See Table A-1 on page 25 for the Ethernet port pinouts. The Ethernet port provides the following:

•10Base-T or 100Base-T with a single connector

•Auto-negotiation

•CSMA/CD

•IEEE 802.3 compatibility

DBU Interface (1700600L2 only)

The NetVanta 3120 has a DBU port on the rear panel to provide analog, V.90 dial backup. See Table A-2 on page 25 for the DBU connector pinouts.

Factory Default Switch

The NetVanta 3120 has a factory default switch (labeled in Figure 3) on the rear of the unit. If the factory default switch is pressed during bootup, the unit will stay in bootstrap mode. Since the unit has no serial port, Telnet has been built into the boot code. The default IP address is 10.10.10.1.
