Viewing and
Understanding
LEDs
Two LEDs appear on the front of the amplier
chassis. One is labeled POWER and appears
as solid red during initial power up, ashes green
during a boot sequence, and appears solid green
when fully booted.
The STATUS LED uses the following indicators to
provide information about the module:
• Flashing red – No network connection found.
• Solid blue – The amplifer is in an uninitialized
state and is not associated to a server. (The
server may be in a discovery mode.)
