Replacing Modules
Modules can be removed and inserted (separately or at the same time)
without affecting normal call processing. Leave the system power on.
CAUTION:
■ This section does not apply to the processor or power supply.
■
Although the system is designed for modules to be removed
and replaced without affecting call processing, partially
inserting and removing a module can cause a cold start.
■ Adding a 100D module or changing any of its DS1
parameters requires that the system be idle.
■ When replacing a module, be sure to use the same module
type. For example, do not put an 008 MLX module in place of
400 GS/LS/TTR. 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 occurs.
■ If you move any module to a different slot, be sure to
renumber the modules by selecting
Board Renumber
from
System Programming.
See the “System Programming” guide for information on
Board Renumber.
