The subsystem has a novel approach to stabilizing the temperature within the

subsystem: When the intelligent sensors on the backplane detect elevated

temperature, such as high ambient temperature or the failure of any cooling or PSU

module, the system will turn the cooling fans to high speed to extract more heat.

Once the ambient temperature cools down to normal or the failed modules have been

replaced, the cooling fans will return to low speed.

3.3 Audible Alarm

Different controller environmental and operational parameters (like temperature, etc.) have

been assigned a range of values between which they can fluctuate. If either the upper or lower

thresholds are exceeded, an audible alarm will automatically be triggered. The alarm will also

be triggered when an active component on the subsystem fails. If the SecurStor 16i manager is

onsite and hears an alarm, the manager must read the error message on the PC terminal or

RAIDWatch screen to determine what has triggered the alarm. After determining what has

occurred, the SecurStor 16i manager must take appropriate actions to rectify the problem.

WARNING!

If an alarm is triggered it is necessary for you to determine the problem.

If the audible alarm is ignored and the problem is not rectified,

unexpected damage may occur.

3.3.1 Default Threshold Values

Table 3-7 shows the default threshold values for the EMD SecurStor 16i

subsystem. If any of these values are surpassed, the alarm will sound:
