Communications System Hardware Requirements
The following communications system equipment is required to install the MERLIN
Messaging System:
- A properly functioning MERLIN LEGEND Communications System, Release 7.0
with a 391A3 (for plastic carrier) or newer power supply module installed
in the same carrier as the MERLIN Messaging System module.
In a multi-carrier system, it is highly recommended that all power supplies
be a 391A3 or newer power supply.
or
- A properly functioning MERLIN MAGIX Integrated System, Release 1.0/1.0i
or later with the following:
- For a metal carrier, a 491D1 or newer power supply module installed
in the same carrier as the MERLIN Messaging System module.
- For a plastic carrier, a 391A3 or newer power supply module installed
in the same carrier as the MERLIN Messaging System module.

Note:
|
The 391A1 and 391A2 power supply modules cannot be installed in the same
carrier as the MERLIN Messaging System module. |
- One available slot in the communications system carrier.

Note: |
The communications system assigns logical IDs and extensions to each port
on the MERLIN Messaging System module.

For MERLIN LEGEND System Maintenance, System Inventory and System Setup reports,
the MERLIN Messaging System module is reported as an 008OPT Module. For the
same reports on an MERLIN MAGIX system, the MERLIN Messaging System is reported
as MERLINMsg.
For module replacement and unit load requirements, refer to System Planning
for the communications system.
