An Injector Ejector handle that interfaces with a mechanical switch is used to provide hot swap functionality The handle has a captive thumbscrew that activates the hot swap switch and locks the handle securely on the Fan Trays front panel The Shelf Managers monitor the Fan Trays through the two independent bussed IPMB connections When the Fan Tray is first inserted into the system the fans incrementally start at full soeed and then decrease to 25 of full soeed The circuitry on board the Fan Tray uses pulse width modulation to control the speed of all the fans Lower speeds reduce acoustic noise and increase the longevity of the fans The speed of each individual fan is monitored If any of the fan speeds drops below or increases above the desired fan speed a System Event Log SEL entry is logged by the Shelf Manager The Shelf Manager then generates alerts and sets alarm conditions as necessary The system is designed to run indefinitely with any single fan failure When one fan fails all other fans are increased to full soeed The Fan Tray has sufficient cooling capacity to keep the Shelf cooled with a single fan failure Unlike the ATCA Blade FRUs the Fan Tray does not negotiate for power with the Shelf Manager and it does not start out at Power Level 0 as specified in the PICMG 3 0 power management mechanism This ensures that the fans start up immediately upon insertion Figure 19 Fan Tray Front and Rear View
