Expanding An Existing System; Installing An Additional Network (Pstn Or Isdn) Module; Installing Additional Extension Modules Or A Broadband Module - Mitel 300 Installation And Maintenance Manual

Expanding an Existing system

Modules may be removed and re-inserted in a system without disconnecting the power. See
page 41.
However if additional modules are being installed in a working system it is necessary to power
the system down before installing an MDF or Backplane.
If additional network modules are to be installed in spare slots, the system needs to be reset
before the switch recognises the new modules.
Installing an additional Network (PSTN or ISDN)
module
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 MDF.
Pressing the reset button will invoke a warm reset and clear any calls in
progress
Installing additional Extension modules or a
Broadband Module
The system must be powered down before installing an additional MDF on the Backplane.
When the MDF is installed it is recommended that the Module and any additional Network
modules that may be required, be installed before the system is powered up. When the
system is powered up the additional modules will be recognised by the system.
The power must be disconnected before installing an MDF or
Backplane. If Battery Back up is provided ensure the BBU switch is off
and the mains is disconnected.
