Preparing the MERLIN LEGEND 
System

Follow these steps to prepare the MERLIN LEGEND system for upgrading to 
the MERLIN MAGIX Release 1.5 system:
1. Remove any of these unsupported modules:
■ 008 (ATL)
■ 400 LS
■ 400 LS/TTR
■ 408 LS (ATL)
■ 408 GS/LS (ATL)
2. If you are upgrading to a MERLIN MAGIX Release 1.0 system, move 
modules to the left of the carrier as necessary to eliminate any empty slots. 
If adding a 100R INA module (requires a metal carrier) only one empty 
slot is allowed before the 100R INA module, otherwise no empty slots 
are allowed. Add more modules to fill the empty slots or upgrade the entire 
system to a metal carrier system.
3. Do a board renumber each time you remove or move a module.
4. Relabel extensions.
5. Back up the system onto a floppy disk or a PC (not onto the PCMCIA card).
