Damage to the device due to inadequate cooling
If the ventilation slits are fully or partly covered, the temperature inside the housing can rise
and exceed the maximum permitted temperature causing damage to the device.
The ventilation slits are located on the side panels of the housing. During installation, select
a mounting position so that the ventilation slits are always free so that the air can circulate.
The clearance to the ventilation slits of the housing must be at least 10 cm.
You will find information about cleaning the air filter in the section "Upkeep and
maintenance".
Close unused module slots of modular devices with dummy covers. Open module slots
impair the air circulation and can damage the device.
If you mount a SCALANCE XR524-8C or SCALANCE XR526-8C in a rack, leave at least
one height unit free above and below.
Warming and premature aging of the IE switch due to direct sunlight
Direct sunlight can heat up the device and can lead to premature aging of the IE switch and
its cabling.
Provide suitable shade to protect the IE switch against direct sunlight.
