Central Bell
If a central bell is required, connect it to a spare extension position and include the extension in the Ringing
Groups that require the bell.
Expanding an existing system
Modules may be removed and re-inserted in a system without disconnecting the power. See page 45.
However, if additional modules are being installed in a working system, it is necessary to power the system
down before installing a module or backplane.
If additional CO Line modules are to be installed in spare slots, the system needs to be reset before the
switch recognizes the new modules.
Installing an additional CO Line Module
CO line modules can be installed in spare slots on the system without powering the system down. However
the module will not be activated until the system is reset. This can be achieved by pressing the reset button
on the CCU.
Pressing the reset button will invoke a software reset and clear any calls in
progress .
Installing additional Extension Modules or an Internet Router Module
The system must be powered down before installing an additional module on the backplane. It is
recommended that the module, and any additional CO line modules that may be required, be installed
before the system is powered up. When the system is powered up, the additional modules will be
recognized by the system.
The power must be disconnected before installing an Extension or Internet
Router Module or backplane. If battery back-up is provided, ensure the BBU
switch is off and the main AC power source is disconnected.
