Product Overview
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
the fan.
