LEDs
The PremierWave 2050 contains several external signals that are intended to drive external
status LEDs. The LEDs are listed below. The signals may be connected as shown in the
reference schematic figure below.
Note:
The System LED usually remains
on
. When the
Default
button is pressed for 7
seconds, the System LED starts blinking every second to indicate the default button can
be released to complete resetting the unit to factory default. The unit reboots after
release of the
Default
button. A lit WLAN LED indicates the STA interface is associated
with an access point.
