The front panel interface (Figure 3-1) allows you to configure network, port, and
SNMP parameters and troubleshoot the unit using loop tests and BERTs without
having to physically connect a terminal to the unit. The interface screen can be
manipulated using the three front panel buttons. The interface screen and the LED
indicators allow you to see the unit’s status.
