power outlets for use with the AC power supply. There is no ON/OFF switch on the

operation. The cooling features of the chassis include a solitary fan with vent holes
on two sides of the chassis designed to draw cool air through one side and vented
out of the opposite side.
Intake Fans A single intake fan provides cooling air for the Acme Packet 1100. The fan — located
o
n
the left side of the chassis — blows cool air over electronic components from the
left side of the chassis and vents heated exhaust air through the right side of the
chassis as illustrated below.
