Environment

Selenio frames are cooled by forced air drawn in from the front of the frame and exhausted through vents between the back modules at the rear of the frame. There must be free passage for air flow on to allow for adequate ventilation.

The Selenio Frame requires an ambient temperature of between 32° to 104°F (0° and 40°C), with a relative humidity of 10-90% (non-condensing). The frame can only maintain proper operating temperatures when the front panel is closed.

The SEL-FR3 frame occupies a vertical space of 3RU. It uses standard front mounting ears located on the frame chassis. You must provide adequate space behind the mounting ears, and clearance for the connecting cables at the rear of the frame.

Caution

CAUTION

To ensure proper ventilation, keep the front panel closed, and install blank back modules behind empty module slots. The frame will overheat if you do not observe these precautions.
