The GS1920-8HPv2 is a compact and fanless Switch capable of supplying Power over Ethernet (PoE).
Certain action will be taken when the temperature of the GS1920-8HPv2 reaches the temperature
thresholds. Please see the table below for how the mechanism works.
Note: The GS1920-8HPv2 will generate logs messages for the situations listed in the

TEMPERATURE AC TIO N
74°C/165.2.°F When the temperature of the GS1920-8HPv2 reaches this temperature threshold, the
SYS
LED will become steady red. See Section 3.3 on page 40 for more information on the LEDs.
To cool down the GS1920-8HPv2, make sure there is enough clearance for ventilation. See
Chapter 2 on page 28 for more information. You can also relocate the GS1920-8HPv2 to a
cooler place.
79°C/174.2.°F If the temperature keeps climbing and reaches this temperature threshold, PoE will be
turned off automatically.
Below 74°C/165.2.°F PoE will be turned on again when the temperature drops and remains below this
temperature threshold for a 30-minute period.
