Fan Tray
The fan tray is responsible for cooling the entire chassis and interfacing with environmental monitors to trigger
alarms when conditions exceed thresholds. The fan tray supports Online Insertion and Removal (OIR).
The fan tray contains four high-efficiency fans with variable speed settings and thermal sensors. If one fan
fails, the speed of the others is increased and a minor alarm is triggered. If a major fan tray failure occurs, the
system is shut down. The individual fans are not field replaceable; the entire fan tray must be replaced in the
event of a major fan tray failure. See Removing the Fan Tray for additional information about the fan.
