3000/3010 System Manual
Each SCU is shipped in its own cardboard shipping carton. Open the carton carefully
and avoid deep penetration into the carton with sharp objects. After removing the unit
from the carton, unwrap the bubble-wrap and pull the unit from the anti-static plastic
bag.
Inspect the unit for possible damage. If the equipment has damaged in transit, file a
claim with the carrier, then contact ADTRAN Customer Service.
1.3
Remove the Current SCU from the Shelf
The removal of the SCU will not disrupt the flow of data through the shelf, Cell
Switch Modules, MUX modules or access cards. A temporary loss of communication
with the shelf as well as the loss of monitoring and recording alarms will occur while
the SCU is being replaced. Since the SCU is not in the data path, no data will be
affected.
1.3.1
Logoff the system
1. From the Total Access Main Menu, select option 6, Logoff, and press <Enter>.
2. From the Exit and Logoff screen, Enter Y and press <Enter>.
1.3.2
Remove the SCU
1. Gently but firmly pull down on the faceplate ejector tab until the unit is unseated
from the backplane.
2. Slide the unit completely out of the shelf and place in an anti-static bag or on an
anti-static surface.
1.4
Install the Replacement SCU into the Shelf
1. Gently but firmly push the replacement SCU into the now empty far-left slot
labeled SCU. Simultaneous thumb pressure at the top (above the Four-Character
Display) and bottom (below the DB-9 connector) of the unit will ensure a good
seat of the SCU pins into the backplane connector.
2. Push the ejector tab close and against the SCU faceplate.
3. Verify that the SCU power-on self test routine is successfully completed. The
sequence on the SCU faceplate is:
1.) HST and ACO green LEDs will blink rapidly several times.
2.) Four-character display will flash all LEDs momentarily.
3.) All LEDs will extinguish except HST if the SCU is designated or defaulted to
Host mode. In that case, the HST will remain lit.
4.) Four-character display will cycle through the “CRAFT baud”, “Ethernet”,
Inband”, and “CPU load” messages.
Power-on self test is complete.
