Upgrading an Existing System
If you are upgrading a MERLIN 11 System with Feature Module 1 or 2 to a MERLIN II System with Release 3 or a MERLIN II System with Feature Module 1 m a MERLIN 11 System with Feature Module 2, you may need to do some site preparation work before installing the new modules that make up the upgraded control unit.
SITE PREPARATION Although the customer should have the control unit site prepared, you may need to complete the job with the construction of one or more jack fields. Consider the following:
Be sure that there is a complete set of planning forms for the system to which you will upgrade, that is, a complete set of Release 3 planning forms if upgrading from either Feature Module 1 or 2, or a complete set of Feature Module 2 planning forms if upgrading from Feature Module 1.
If you are extending the capacity of the control unit be sure there is adequate backing to mount an Expansion Carrier onto the Basic Carrier. If necessary, mount a backboard on the wall next to the Basic Carrier to provide for the Expansion Carrier. See “Mounting the Expansion Carrier” on page
If additional CO lines were installed, and if there is a jack field for those lines, you may need to enlarge that jack field. If no jack field exists, you may decide that one should be built. See “Jack Field Wiring” on page
