Installation Guide

Safeguards are built into all Extreme Networks switches and power supply units to minimize the risk of
fire.
Table 109: Thermal Shutdown and Restart Behavior
Switch Model(s) Behavior
All models except
those listed below
When internal system temperatures exceed the thermal shutdown temperature
limit (typically about 20°C higher than normal system operating temperatures),
the system’s power supplies are turned o and the switch shuts down. The
system remains in the OFF state until the system has sucient time to cool and
the internal thermal sensor measures a temperature lower than the maximum
specified ambient temperature, at which time the system restarts automatically.
Alternately, you can restart the system immediately by removing and then
restoring all line power to the system.
X430-8p The switch is not equipped with a mechanism for thermal shutdown. When
internal system temperatures exceed the thermal shutdown temperature limit
(typically about 20°C higher than normal system operating temperatures), the
system reboots and immediately restarts. You then have the option, through the
command-line interface, of allowing the boot cycle to continue:
ALERT: Switch rebooted after reaching emergency shut-off
temperature.
Please evaluate the situation and make sure the causes
of switch
overheating are fixed before continuing.
Continue booting? (Y/N)
Alternately, you can restart the system immediately by removing and then
restoring all line power to the system.
X430-24t
X430-24p
X430-48t
The switch is not equipped with a mechanism for thermal shutdown. When high
operating temperatures are experienced, the system fans are set to full speed and
the switch remains powered.
Alternately, you can restart the system by removing and then restoring all line
power to the system.
X460-G2
(all models)
When internal system temperatures exceed the thermal shutdown temperature
limit (typically about 20°C higher than normal system operating temperatures),
the system’s power supplies are turned o and the switch shuts down. The switch
does not restart automatically, even after cooling. It remains in the OFF state until
you remove and then restore all line power to the system.
Table 110: Ambient Temperature Range for Switches
Switch Series Ambient Operating Temperature Range
X430 0°C (32°F) to 45°C (113°F)
Note: The maximum temperature is 40°C (104°F) for X430-8p model switches.
X440-G2 0°C (32°F) to 50°C (122°F)
Note: The maximum temperature is 60°C (140°F) for the following models: X440-
G2-12t8fx-GE4, X440-G2-24fx-GE4, X440-G2-24t-GE4.
X450-G2 0°C (32°F) to 50°C (122°F)
X460-G2 0°C (32°F) to 50°C (122°F)
