3.7.2 Hardware Monitor

Enter “Hardware monitor” function to view the information of current voltage,

temperature, power supply, and fan status.

If “Auto shutdown” has been checked, the system will shutdown automatically when

voltage or temperature is out of the normal range. For better data protection, please

check “Auto Shutdown”.

For better protection and to avoid single short period of high temperature triggering

Auto shutdown, the iSCSI RAID subsystem use multiple condition judgments for Auto

shutdown, below is the detail of when the Auto shutdown will be triggered.

1. There are 3 sensors placed on the controller for temperature checking, on core

processor, on PCI-X bridge, and on daughter board. The iSCSI RAID subsystem

will check each sensor every 30 seconds. When one of these sensors is over the

high temperature value for continuous 3 minutes, the Auto shutdown will be

triggered immediately.

2. The core processor temperature limit is 85°C. The PCI-X bridge temperature limit

is 80°C. The daughter board temperature limit is 80°C.

3. If the high temperature situation doesn’t last for 3 minutes, the subsystem will not

do auto shutdown.
