UIM-DS3 Installation in a Mini DSLAM
a. Remove the (8) screws securing the Mini DSLAM chassis and carefully lift off the chassis
cover. Set the screws aside.
b. Select a port on the Mini DSLAM for UIM-DS3 installation; either port (1 or 2) may be
used. Although not required for operational purposes, if redundancy is desired, two UIMs
may be installed in the Mini DSLAM, one in each port.
c. Remove the blanking plate* from the selected port.
d. Carefully slide the faceplate of the UIM-DS3 under the inside lip of the Mini DSLAM at
the selected port opening such that the UIM-DS3 circuit board is facedown and the UIM-
DS3 label shows through the port opening with the model name along the right-hand
edge.
e. Ensure the mounting holes on the UIM-DS3 are lined up with the corresponding pems on
the Mini DSLAM board and the board-to-board connector key pins are properly aligned.
f. Gently press down with even pressure on all four corners of the UIM-DS3 until the board-
to-board connector is fully seated.
g. Secure the boards together at the pems with the (4) provided panhead screws.
h. Secure the UIM-DS3 faceplate to the front of the Mini DSLAM chassis using the (2)
provided beige flathead screws.
i. Replace the Mini DSLAM chassis cover and secure with the original (8) screws.
CAUTION
Disconnect all power sources from the Mini DSLAM before installing the UIM-DS3.
CAUTION
*Blanking plates should be stored for possible future use. If a UIM-DS3 is removed from a Mini
DSLAM, it must be replaced with either another UIM or a blanking plate. DO NOT OPERATE A MINI
DSLAM WITH AN EMPTY UIM PORT.
