OPERATION
3.1 Front Panel Description
The switch front panel (Figure 3-1) provides the local interface to configure, operate, and
monitor the switch:
•
A 48-character, 2-line LCD display in the upper-front panel displays options and
status for the operator.
•
Nine LEDs grouped under the LCD display provide mode and fault status at a
glance.
•
A 16-key keypad to the right allows the operator to perform setup, configuration,
and operation functions.
•
An audible beeper signals the pressing of a keypad key.
The display, LEDs, and beeper are mapped into address space of the external bus
structure. The display updates every second, and the LEDs and beeper update as needed.
