Installation Instructions
AT-NT117 (AC) and AT-NT118 (DC)
ADSL Mini-DSLAMs
The following instructions provide installation procedures for the AT-NT117 (AC) and AT-NT118 (DC) ADSL Mini-
DSLAMs. Allied Telesyn strongly recommends using proper static protection techniques when installing
and handling this equipment.
Installation Instructions
Step #1 - Unpack and inspect the AT-NT117 or AT-NT118.
You should have the following components:
1) One AT-NT117 or AT-NT118
2) Power cord (for the AT-NT117 only)
3) Rubber feet (4)
4) Rack mount brackets (2)
5) Rack mount bracket screws (10)
If there is visible damage, do not attempt to connect the device; contact Allied Telesyn Technical Support
for assistance.
Step #2 - Install the Uplink Interface Module (AT-NT510, AT-NT530, AT-NT540, AT-NT550, or
AT-NT560). DO NOT POWER UP THE AT-NT117 OR AT-NT118 UNTIL AFTER THE UIM HAS BEEN
INSTALLED.
Unscrew the AT-NT117 or AT-NT118 chassis, using a Phillips screwdriver and carefully lift off the top half
of the chassis; set aside. Remove the blanking plate from the slot selected for the UIM (either slot may be
used). Carefully position the UIM with the faceplate facing out of the vacated slot. Ensure that the
connector between the UIM and the AT-NT117 or AT-NT118 is fully aligned. Secure the UIM in place with
the four provided screws. Replace the chassis top and reattach with all eight screws.
Step #3 - Site selection
When selecting a site for the AT-NT117 or AT-NT118, please consider the following:
§ Maximum recommended ambient temperature is 65°C. Internal temperatures of rack should be
considered.
§ Ensure that the unit is placed in such a manner that the cables will not become a tripping hazard or
become dislodged from the unit.
§ Do not block power supply vents or otherwise restrict airflow when installing unit in rack.
§ Mechanical loading of rack should be considered so that the rack remains stable and unlikely to tip
over.
§ Consideration of the overall loading of the branch circuit should be given before installing any
equipment in a rack environment.
§ Ensure that a reliable grounding path is maintained in the rack system. This unit is intended for a
grounded connection.
For tabletop mounting, attach the rubber feet to the bottom of the unit. For rack mounting, attach the rack
mount brackets to the sides of the unit at the desired position with the provided screws.
Step #4 - Powering up the AT-NT117 or AT-NT118. Connect power to the AT-NT117 or AT-NT118 from
an appropriate power source. The AT-NT117 uses AC power. Turn on the power switch located on top of
the AC inlet. Verify that the PWR LED is illuminated.
