1.15 Enclosure Cooling
Attention: Limit the amount of time that the enclosure is extended out of the rack to only
what is necessary to exchange a component or perform regular maintenance and should be
limited to a maximum of 5 minutes total. Never extend the enclosure out for longer than 5
minutes to prevent overheating. Only extend the enclosure out of the rack as far as necessary
to service components. The enclosure is equipped with a sensor that will be tripped when
the enclosure's top cover has been opened resulting in the rear fans increasing to max speed.
In the event that a fan has failed, it must be replaced before any other CRUs and should be
removed from the enclosure within 30 seconds of removing the enclosure cover.
