Dell MD3220 Storage Array Thermal Shutdown, System Password Reset, Shutdown Threshold Type

Storage Array Thermal Shutdown

The system automatically shuts down when system temperature exceeds the safe threshold. The battery backup unit protects against data loss by providing power to offload cache to non-volatile memory in the event of power loss. It is not necessary to shut down any MD1200 Series expansion enclosures attached to the storage array when thermal shutdown occurs.

Temperature threshold values determine the temperature at which shutdown occurs. These thresholds cannot be changed.

Table 3-1. Shutdown Threshold Type

Threshold Temperature Exceeding	Event Description
Nominal failure threshold	A critical event is set
Maximum failure threshold	Shutdown of the system power supplies occurs
	within 3 minutes
Shutdown threshold	Shutdown of the system power supplies occurs
	within 5 seconds

System Password Reset

The storage array password can be reset if it is forgotten. To reset the password, push and hold down the password reset switch for at least 5 seconds. The password is deleted. See Figure 3-1 to locate the password reset switch.

The RAID controller module allows you to change the password. For more information about setting your password, see "Setting a Password" on page 71.

NOTE: The reset switch can be accessed by using a small object such as the tip of a pen.
