BREAK-FIX PROCEDURES
General
This chapter refers only to replacement of removable modules and plug-ins, not of
other components of the unit. If any other components in the unit require replacement,
contact your local service center
Before replacing modules or plug-ins, see safety issues/warnings in the Installation
chapter above.
For information on installation of the frame/housing on the wall, see the Installation chapter
above.
The ACE3600 has a hot swap capability, which means that the modules can be removed from
their slots and inserted without powering down the unit. The only exception to this rule is the
main power supply module, which cannot be removed during normal operation. See
Replacing a Power Supply Module below for details.
If a module is inserted once the system is running, the system will recognize the module, but
will not operate it using the application until the unit has been rebooted.
