Installing the MUM in an IP DSLAM chassis.
The 12000E is a fourteen slot chassis; slots 1–12 are reserved for access modules
and slots U1 and U2 are reserved for Multiplexer Uplink Modules (MUMs). The
4000E is a five slot chassis; slots 1–4 are reserved for access modules and slot U1
is reserved for a MUM.
Procedure
To install a MUM:
1. Align the MUM with the slot module guides of the chosen slot for installation
(either slot U1 or U2 on the 12000E or slot U1 on the 4000E).
2. Slide the MUM carefully but firmly into the chassis until it is fully seated.
3. Tighten the fastening screws on the MUM faceplate.
4. Verify that the PWR (Power) LED on the MUM faceplate is illuminated.
Installing the UIM in a Mini DSLAM
Caution:
Disconnect all power sources from the Mini DSLAM before installing the
UIM.
Procedure
To install a UIM in a Mini DSLAM:
1. Remove the eight screws securing the Mini DSLAM chassis and carefully lift
off the chassis cover. Set the screws aside.
2. 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.
3. Remove the slot cover from the selected port.
Store slot covers for possible future use. If a UIM is removed from a DSLAM, it
must be replaced with either another UIM or a slot cover. Do not operate a
Mini DSLAM with an open UIM slot.
4. Carefully slide the faceplate of the UIM under the inside lip of the Mini DSLAM
at the selected port opening such that the UIM circuit board is face down and
the UIM label shows through the port opening with the model name along the
right edge.
5. Ensure the mounting holes on the UIM are lined up with the corresponding
pems on the Mini DSLAM board and the board-to-board connector key pins
are properly aligned.
6. Gently press down with even pressure on all four corners of the UIM until the
board-to-board connector is fully seated.
