Airflow
Airflow is routed into the mainframe rear and exhausted
out the left side (viewed from the front with E8408A in
horizontal position). When the mainframe is rack-mounted,
allow 50 mm of clearance at the rear and left side for proper
air flow.
Fan Speed
(Cooling Mode, High or Variable set by front panel switch)
High fan speed mode: Maximum airflow all the time
Variable fan speed mode: Fan speed changes between high and
low as a function of ambient and power
supply temperature.
