Mitel 470 as of R4.1
syd-0585/1.2 – R4.1 – 08.2016
Trigger condition
Time synchronization via the NTP server (NTP =
Network Time Protocol) has been restored.
Call rejected by the network
• On any line: error code 34
• On required line group:
error code 44
The temperature inside the communication
server is too high. The appropriate measures
must be taken immediately to improve the heat
dissipation, e.g. by providing the required clear-
ances, lowering the ambient temperature or
installing the fan from the rack-mounting set
(Mitel 430 only).
The temperature inside the communication
server is too high. Appropriate measures must
be taken immediately to improve heat dissipa-
tion. 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 man-
ager card CPU1:
• the communication server will be shut down
completely.
Notes:
• To prevent 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 tempera-
ture sensors and are therefore never deacti-
vated due to overheating.
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:
(see also Tab. 29)
A port previously in operation has stopped func-
tioning.
