Configuring The Fan Ventilation Direction; Configuring The Detection Timer; Configuring Temperature Alarm Thresholds For A Member Device - HP 5800 Series Configuration Manual

Configuring the fan ventilation direction

Some switch models accommodate two fan trays to provide good ventilation. The two fan trays must be the
same model. Two fan models are available for the switch. One model has air flow from the port side to the
PSU side. The other model has air flow from the PSU side to the port side.
Manually configure the fan ventilation direction for the switch (the default direction is power-to-port). The
two fan trays must have the same ventilation direction as the switch. .
If one fan tray or both the two fan trays have a different ventilation direction from the switch, the system
outputs trap and log information for you to replace the wrong ones.
To configure the fan ventilation direction:
Step
1. Enter system view.
2. Configure the fan
ventilation direction
for the switch.

Configuring the detection timer

Some protocols might shut down ports under specific circumstances. For example, MSTP shuts down a BPDU
guard enabled port when the port receives a BPDU. Then, the device starts the detection timer. If the port is
down before the detection timer times out, the device automatically brings up the port.
To configure the detection timer:
Step
1. Enter system view.
2. Configure the detection timer.
Configuring temperature alarm thresholds for a
member device
The switch sends traps when the temperature of a sensor crosses the lower or upper temperature threshold.
Change the temperature threshold settings for the switch as needed so remove the alarm condition in time.
If the temperature is lower than the lower limit, the device logs the event and outputs the log information
•
and trap information for users.
If the temperature reaches the warning threshold, the device logs the event and outputs the log
•
information and trap information for users.
