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 three minutes Shutdown threshold Shutdown of the system power supplies occurs within five 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 about setting your password, see "Setting a Password" on page 69. NOTE: The reset switch can be accessed by using a small object such as the tip of a pen. Planning: RAID Controller Modules 33
