Basic System - Mitel Aastra 470 System Manual

Expansion Stages and System Capacity
The basic system Aastra 470 can be expanded not just with interface cards and sys-
tem modules but also with an applications card (CPU2). The applications card is
supplied with preinstalled operating system, unified communications and multi-
media applications.
The front-side RJ45 sockets of interface cards with 16 or more interfaces are partly
or all four-fold assigned. With the FOP fan-out-panel they can be split again to indi-
vidual sockets.
The Aastra 470 basic system has an integrated fan. The operating reliability of the
communication server can be increased by fitting an optional redundant fan unit.
It is powered by an internal power supply unit (PSU2U). An external auxiliary power
supply unit (APS2) is required for expansions involving a large number of power-
consuming terminals. The auxiliary power supply unit also serves to increase the
operating reliability. If the internal power supply unit fails, the external auxiliary
power supply unit takes over the power supply.
