Basic System - Mitel 470 System Manual

Expansion Stages and System Capacity
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 individual
sockets.
The Mitel 470 basic system has an integrated fan. The operating reliability of the com-
munication 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-con-
suming 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.

For electrical and thermal reasons the dummy covers must always be fitted. They are
removed only to expand the basic system with interface cards or an application card.
