Catastrophic errors
The design of the DS2500 allows it to continue operating in the presence of faulty hardware. However,
a critically-high temperature in the enclosure can cause hardware failure and compromise data integrity.
To prevent catastrophic data loss and further damage to components, the following conditions cause the
DS2500 to shut down:
• A power supply removed from the enclosure
• No operational blowers
• An unacceptable temperature level in the enclosure
If any of these conditions exists, the EMU starts a timer to shut down the enclosure in 7 minutes. If the
condition is corrected before the 7 minute countdown is completed, the EMU aborts the shutdown
and normal operation resumes.
