CHAPTER 6 OPERATION AND MAINTENANCE
Overheat (Mitel 470
only)
The temperature inside the
communication server is too high.
Appropriate measures must be
taken immediately to improve heat
dissipation. Measures are
automatically adopted, depending
on where the overheating occurs:
FXO and FXS interface card:
• the ports are deactivated in
groups of 4 ports.
• Once they have cooled down
below a defined card-specific
value, the ports are automati-
cally reactivated group by
group.
CPU2 applications card
• The card will be completely
deactivated. Once it has
cooled down below a defined
value, the card is automati-
cally reactivated.
Internal power supply unit PSU2U
or call manager card CPU1:
• the communication server will
be shut down completely.
NOTE:
• To revent the system from
overheating, no more than
30% of the FXS ports should be
active simultaneously per
32FXS card and no more than
50 FXS ports per system.
• PRI, BRI and DSI cards do not
have temperature sensors and
are therefore never deacti-
vated due to overheating.

Overload detected on
USB port (CPU2) (Mitel
470 only)
A (current) overload was detected
on one of the USB interfaces on the
applications card (CPU2).
NOTE: The maximum current input at
the USB interfaces varies.
