Maintenance procedures

Faults can be rectified on site by replacing faulty modules or PCBs

Hot Swapping faulty modules

The Network modules can be replaced without powering the system down.

If a Network module is replaced by the same type of module e.g. Analogue by Analogue, the switch will

return to normal operation when the new module is inserted

If a Network Module is to be replaced by a different type of Network Module (e.g. an Analogue module

replaced by an ISDN module) the system must be reset, by pressing the reset switch in the CCU MDF

area, so that the system can recognise the new module type.

If an ISDN line is replacing an analogue line ensure the analogue line cable is

disconnected before connecting the ISDN Line or installing the module. The same

applies if an analogue line replaces an ISDN line.

The Ports Modules can be removed and replaced without powering down the system

The Options Module can be removed and replaced without powering down the system

The Voice module can be removed and replaced without powering down the system.

When a voice module is replaced all recorded messages and greetings are lost.

The Internet Module can be removed and replaced without powering down the system.

The Primary Rate ISDN Module can be removed and replaced without powering down the system.

The MOH Module can be removed and replaced without powering down the system.
