IEEE 802.3 compatibility
DBU Interface (1700600L2 only)
The NetVanta 3120 has a

Factory Default Switch
The NetVanta 3120 has a factory default switch (labeled in
) 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.
