c. Remove the blanking plate* from the selected port.
d. Carefully slide the faceplate of the UIM under the lip of the MUM faceplate at the
selected port opening such that the UIM circuit board is facedown and the UIM label
shows through the port opening with the model name along the right-hand edge.
e. Ensure the mounting holes on the UIM are lined up with the corresponding pems on
the MUM 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 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 faceplate to the MUM faceplate using the (2) provided beige flathead
screws.
Install the MUM in an IP DSLAM chassis.
The IPD12000 is a fourteen slot chassis; slots 1-12 are reserved for Access Modules and
slots 13-14 are reserved for Multiplexer Uplink Modules (MUMs). The IPD4000 is a five
slot chassis; slots 1-4 are reserved for Access Modules and slot 5 is reserved for a MUM.
a. Align the MUM with the slot module guides of the chosen slot for installation (either
slot 13 or 14 on the IPD12000 or slot 5 on the IPD4000).
b. Slide the MUM firmly into the chassis. DO NOT USE EXCESS FORCE.
c. Tighten the fastening screws on the MUM faceplate.
d. Verify that the PWR (Power) LED on the MUM faceplate is illuminated.
UIM 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 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.
CAUTION
*Blanking plates should be stored for possible future use. If a UIM is removed from a MUM, it
must be replaced with either another UIM or a blanking plate. DO NOT INSTALL A MUM WITH AN
EMPTY UIM PORT INTO AN IP DSLAM.
CAUTION
Disconnect all power sources from the Mini DSLAM before installing the UIM.
