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.
