Setting Up and Testing the Desktop Unit
Campus-RS Desktop Unit User Manual 2-9
TEST THE HDSL PORT
It is recommended that you test all Desktop Units at your location prior to
installing units at a remote site. This minimizes additional trips to the remote
site to troubleshoot problems.
It is also possible to test a Desktop Unit with a Line Unit installed in a
Campus-Star chassis. This requires creating a cable to connect the HDSL port
on the Desktop Unit to the port on the Campus-Star. Refer to the Campus-Star
user manual for the Campus-Star HDSL port pinouts.
1 If you have not already done so, follow the instructions in “Surge
Protection” on page 2-1.
2 If you have not already done so, connect each Desktop Unit to a power
source.
3 Turn on the power to each Desktop Unit, using the power button on the
back panel.
Each unit performs a power-on test. After completing the test, the HDSL
LED on each unit flashes red and the LCD displays:
MARGIN (LOC/RMT)
1:XX/XX 2:XX/XX
This indicates successful completion of the power-on test. If either unit
fails the test, the LCD displays an error code. If this happens, contact
ADC, following the instructions in “Product Support” on page C-1.
To establish an HDSL link, the HDSL transmission rate must
be the same for each unit. Unless you have changed the
HDSL transmission rate for one of the units, both will be set
automatically to the factory default.
