UIM1-A2-GZ40-00
Using the UIM an IP DSLAM
Use of the UIM in a multi-slot IP DSLAM requires that you install the UIM in a
Multiplexer Uplink Module (MUM), then install the MUM in the DSLAM chassis.
Installing the UIM in a MUM
The UIM may be attached to a MUM that has already been in service, although
you must remove the MUM from the IP DSLAM in order to do so. Removal of a
MUM from an IP DSLAM chassis that is powered up will not affect the operational
status of other modules within the chassis; it will, however, disengage the IP
DSLAM's upstream network connection.
Procedure
To install the UIM:
1. Place the MUM on a flat surface with the circuit board facing up.
2. Select a port on the MUM 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 on the MUM.
3. Remove the slot cover from the selected port.
Store slot covers for possible future use. If a UIM is removed from a MUM, it
must be replaced with either another UIM or a slot cover. Do not install a MUM
with an open UIM port into an IP DSLAM.
4. 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 face down and the
UIM label shows through the port opening with the model name along the right
side.
5. Ensure the mounting holes on the UIM are lined up with the corresponding
standoffs on the MUM 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.
7. Secure the boards together at the standoffs with the four provided panhead
screws.
8. Secure the UIM faceplate to the MUM faceplate using the two provided
flathead screws.
