Replacing a Module

Replacing a Module
!
CAUTION:
This section does not apply to the processor or power supply.
Although the system allows you to remove and replace modules without
affecting call processing, partially inserting and removing a module can
cause a cold start.
To add a 100D module or change any of its DS1 parameters, the system
must be idle.
When you replace a module, use the same module type. For example, do
not put a 008 MLX module in place of a 400 GS/LS/TTR module. If a
module is replaced with another type of module, or if a module is added to
the system without powering down the system first, a cold start (System
Reset) occurs.
If you move any module to a different slot, be sure to renumber the
modules by selecting 7€fƒiÃSpy†xgpƒ from system programming. See
System Programming for information about board renumbering.
NOTE:
You can remove and replace line/trunk and extension modules with the
system power on, without affecting normal call processing.
