The MERLIN Messaging System module can be installed in the first available slot. There is no required order for module installation in the communications system carrier, other than the processor module in the first slot. The MERLIN Messaging Module is usually installed in the first available slot following the installation of other modules to ensure numerical continuity for extensions in the communications system dial plan.
Note: |
No more than three modules that require 5 Volts should be installed in the same communications system carrier. Communications system modules that require 5 Volts include the Processor Module, the T1 Module, and the MERLIN Messaging System Module. |

1
|
If you are installing a MERLIN Messaging module in a plastic carrier, you must first install the module in the 100A Clamshell Housing. |
See CIB 3219 that comes with the 100A Clamshell Housing Kit for instructions. |
|
2 |
Install the PC Card containing port licensing information in the left-most PCMCIA slot. |
If the PC Card is installed in the right-most PCMCIA slot, the RMD will not function. |
|
3 |
Power down the communications system. |
Be sure to disconnect the power cord. |
|
4 |
Install the MERLIN Messaging System module in the first empty slot in
the communications system carrier, as follows:
For installation in a metal carrier:
|
A damaged carrier or module must be replaced. To avoid damage, do not force the module. If the module does not insert easily, press the bottom-rear locking tab (plastic carrier) or insert a screw driver in the opening at the bottom of the module's faceplate (metal carrier) to release the module. Then remove the module and inspect the module and carrier for damage or obstruction. If there is no damage and no obstruction, re-insert the module. |
|
5 |
Power up the communications system. |
Be sure to power up the carrier containing the processor module last. |
Once you install the MERLIN Messaging System module, do the following:
