Fans
The Acme Packet 4600 chassis pulls cool ambient air into the chassis through five front-installed intake fans and exhausts heated air through perforated air outlets located along the rear of the chassis. To avoid overheating the system, do not block the air intake or exhaust or otherwise obstruct airflow to the system in any way.
Each individual fan attaches to the chassis with two captive screws, and is powered by a
connector that joins the fan to the motherboard when screwed into the chassis.
The Acme Packet 4600 automatically adjusts the fan speed based on the current operational status and environmental conditions. Fan speed regulation is an automated process that requires no user intervention. You can monitor the status of the fan speed from the Environment menu of the graphic display.
Each fan is a user-replaceable, hot-swappable component. If the Acme Packet 4600 experiences a fan malfunction and generates an alarm, you must remove the existing fan and replace it with a fully functioning fan.
