UIM-E3 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-E3 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-E3 under the inside lip of the Mini DSLAM at the
selected port opening such that the UIM-E3 circuit board is facedown and the UIM-E3
label shows through the port opening with the model name along the right-hand edge.
e. Ensure the mounting holes on the UIM-E3 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-E3 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-E3 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-E3.
CAUTION
*Blanking plates should be stored for possible future use. If a UIM-E3 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.
