Installation and Maintenance Manual
Expanding an Existing system
Modules may be removed and
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 (Analogue 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 modules
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.
