6.3 Fan Tray Signals 

The Fan Tray provides signals for: 

  Fuse monitoring 

  Status of the Hot Swap Controller 

  Fan Speed 

  Temperature 

These signals are controlled by the IPM Controller devices on the Fan Tray PCB. The Shelf 
Manager has access to these signals via IPMB. 

 

6.4 Fan Tray Indicators 

The front panel includes a green Fan Tray OK LED, a red Fan Tray Fault LED, and a blue 
Hot Swap LED.  

The Hot Swap push button indicates to the Shelf Managers that the Fan Tray is about to 
be removed. Its use is optional, but it is provided so that service personnel can be trained 
to look for a blue LED to be illuminated on any active component before removing it from 
the system. Once the operator pushes the Hot Swap button, the Shelf Manager is 
informed of the pending extraction. When the Shelf Manager feels it is “safe“ to remove 
the Fan Tray, the blue Hot Swap LED illuminates solid.
