For additional information, see Vertical publication IMI01-005, Handling of
Electrostatically Sensitive Components.

Power-up Initialization (Cold Start)
IMPORTANT!
•
The installation of the DX-120 is complete only when initialization is performed
at the time of startup. This process is required for proper operation of the
system.
• Occasionally it may be required to perform this initialization process after the
original installation, but this is rare.
•
Initialization causes the operational customer database to be established and organized for system operation
and future updating.
•
Once initialization has been completed the default database contents are loaded into operational memory:
the system is ready to run on this database configuration.
•
Customized changes may be made to this database according to the allowable program settings for the
various features.
CAUTION
If you are performing a cold start on a system with an existing customized
database, be sure to back up that database prior to beginning the cold start
procedure. The cold start procedure forces the default database into the
DX-120 switch, overwriting any existing database residing on that switch.
For more details on backing up databases, see the DX-120 Technical
Manual, Volume II, Programming.
