Severity
Overheat (Mitel 470

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
automatically 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 automatically
reactivated.
Internal power supply unit PSU2U
or call manager card CPU1:
• the communication server will
be shut down completely.
Note:
• To revert 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.
