Rack Mounting Ventilation Recommendations
Excessive heat can decrease the optimal lifetime of the power amplier. An over temp
indicator LED on the front panel of the amplier lights red whenever the recommended
operating temperature has been exceeded. See “Front Panel Features and Operation”
on page 9.
To reduce the chances for an over temp condition, the XPAs should be arranged in a
rack environment so that adequate airflow is available both above and below the XPA
whenever possible. No more than two XPAs should be arranged one-on-top-of-the-other
in a rack without an open space between them, as shown in the following illustration. An
XPA can also be arranged above or below another non-XPA device, but there must be an
open space both above and below those devices.
