Chaparral K5312/K7313 ユーザーズマニュアル

You can enable or disable the audible alarm that sounds when the controller becomes 
too hot, detects low or high voltage, or an array becomes critical or offline. Changing 
the mute setting lets you turn off the alarm when it is sounding. You should turn it 
back on after resolving the problem.

The alarm sounds for temperature or voltage conditions (events). Warning events are 
generated when the temperature or voltage enters the warning range. Shutdown 
events are generated when the temperature or voltage enters the shutdown range. 
After reaching the shutdown range, the controller will not function. You must resolve 
the problem and reboot the controller. If the problem is not resolved, it will shut down 
again. 

Alarm conditions trigger an event message that displays in the Disk Array 
Administrator software window and in the event log. See Displaying the Event Log 
on page 5-1.

Table 7-1 shows the temperature and voltage thresholds for each alarm and what to 
do to resolve the problem. 

Table 7-1. Alarm thresholds

CPU temperature

Warning—0°C to 5°C and 
65°C to 70°C
Shutdown—0°C and 70°C
<0°C and >70°C

Check the 

Disk Array

 Administrator software to 

confirm what the alarm means. See Chapter 3, 
Accessing the Disk Array Administrator 
Software.

Check the ambient temperature and lower it, if 
needed. Ambient temperature should be less 
than 45°C.

Onboard temperature

Warning—0°C to 5°C and 
45°C to 50°C
Shutdown—0°C and 50°C
