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.)

1200 MacArthur Blvd. Suite 304,

Mahwah, NJ 07430

• Solid green – The amplifer is registered to a

Nyquist server and is in normal operation.

• Flashing green – The amplifer has an IP

address but is not registered with the Nyquist

server.

• Solid red – The amplifer needs to be reboot-

ed or reset so that the Nyquist application

can resume.

• Flashing Blue – The amplifer is updating.

Using the Reset Button

The Reset button allows you to

restart the amplifer or to reset the

amplier’s conguration settings

to the factory default settings.
