Power Up

Power Up

The front LED indicators and configuration switches are illustrated in

Figure 4

. Upon power-up, the green PWR LED should light and the yellow

CONF LED should illuminate for the duration of module initialization.

Operation Indicator LEDs

With factory default configuration and a valid input signal connected, the
green PWR LED, and one or both of the green signal Channel Lock LEDs
should illuminate when phase lock is achieved for valid AES/EBU input
signals (refer to

Table 1 on page 12

to see the possible operating indicator

combinations).

The yellow COMM LED, when flashing, indicates communication is active
on the frame bus. The LED also goes into a steady long interval flash when
the module receives a Location command from the remote control system,
providing easy visual identification of the module in a rack with multiple
8900 frames.

Figure 4. LEDs and Testpoints

A red FAULT LED indicates an error situation and, with the previously
described LEDs, can indicate the operational conditions presented in

Table 1 on page 12

. The table describes LED indications and the signal

input/output conditions that are indicated.
