NOTE: The firmware reads

 

 

 

 

inlet temperature every 5 secs.

 

 

 

 

If the inlet temperature reaches

 

 

 

 

non-recoverable threshold, the

 

 

 

 

firmware will start to check the

 

 

 

 

power status for each sled and

 

 

 

 

initiate the sled for graceful

 

 

 

 

shutdown (pull-low 4 seconds).
