location.
Inadequate ventilation can result in overheating, possibly
causing damage to the device(s), or even fire. If this device is
to be used in a small space other than an EIA-standard rack,
make sure that there is adequate space around the device: at
least 10cm above, 10cm at the sides and 20cm behind.
• Donotplacethedeviceinalocationwhereitmaycomeinto
