EMU temperat

ure warning and shutdown operation

The EMU uses multiple temperature sensors to monitor enclosure conditions. A sensor is located in:

• Each power supply

• Each disk dr

ive

• The EMU

An algorithm involving data from multiple sensors determines the temperature in the enclosure. The

following occurs when an unacceptable temperature condition exists:

• As the temp

erature approches a critical temperature condition, a noncritical alarm sounds to provide

time for corrective action before shutdown occurs.

• If the temperature reaches a critical level, the EMU activates the alarm and starts a timer which

shuts down

the enclosure in 7 minutes.
