Quick Operation Guide of DS-A81 Series Storage System
Motherboard Information
The information of CPU fan speed, CPU temperature, motherboard fan speed and system
temperature will be monitored. When the fan is abnormal (e.g., low speed) or the temperature is
abnormal (e.g., high temperature), the system shows the corresponding alarm messages.
Chassis Information
The information of the fan speed, temperature information and power supply information of the
chassis will be monitored. Up to 8 chassis fans can be connected depending on different models.
Expansion Enclosure Information
The manufacturer, type, bay number, version, fan speed, temperature and other information of
the expansion enclosure are displayed.
Fan Speed Control
The fan speed of the chassis can be set according to the ambient temperature, to adjust the
internal working temperature of the chassis. Low temperature can help to extend the system life
and reduce the failure rate, but also increase the noise and power consumption. Our storage
system provides 3 working modes of the fan, including high speed, medium speed (default) and
low speed. In the same circumstance, comparing to medium speed, the high speed can decrease
the temperature and the low speed can reduce the noise.
Audio Warning
The system makes the audible warning when the system is in abnormal status. You can click the
mute button to enable/disable the audible warning.
