Precautions for Rack Mounting
Operation of this product is guaranteed in the
temperature range of 0 to 40°C. If mounted in an EIA
standard rack with other equipment, the heat from
each device raises the temperature inside the rack,
which may prevent it from demonstrating its full
performance. To prevent heat buildup, mount the
product in a rack only under the following conditions.
• Leave at least 1U between it and other devices
when mounted with devices that tend to generate
heat, such as power amplifiers. Further, ensure
sufficient ventilation by installing a ventilation panel
in the space, or simply leave it open.
