The temperature sensors in the enclosure (see Chapter 3, “Environmental
Monitoring Unit”) detect overtemperature conditions or blower
malfunctions and alert the user to the problem. Simultaneously, the EMU
causes all the operational blowers to operate at high speed thereby
increasing air flow through the enclosure to increase cooling.
•
When the overtemperature condition is caused either by the intake
temperature or the exhaust temperatures (backplane) being too high, the
EMU initiates routines that can cause a power shut down to occur after
8 minutes.
•
Removing a blower significantly changes the air flow pattern within the
enclosure. The EMU initiates a routine that causes a power shut down
to occur after 8 minutes.
•
When there are two or more non-operating blowers (that is, not
operating or rotating too slowly) in the same blower bank the EMU
initiates a routine that causes a power shut down to occur after
8 minutes.
•
When the error condition is caused by no more than one defective
blower in a blower bank the EMU does not initiate a power shut down.
