The box color next to each channel indicates the current status of the channel:
• Red = data path is known to be failed.
• Black = data path status is unknown.
• Green = data path is known to be good.
The applicable data paths can be verified by viewing the configuration mode pages listed
below.
5.4 Data Path Indications on the Main and GIA Configuration Pages

configuration pages. Post GDU 9.11 software uses green check, red x, black N/A,

uses pre GDU 9.11 boxes in the troubleshooting tables, the technician should be
aware of the differences.
