Operation
System Overheating
Cooling vents
Inproper cooling can lead to blade and system damage.
To ensure proper cooling and undisturbed airflow through the system always operate the
system in a horizontal position and keep clear at least 60 mm at the back and 60 mm to each
side of the system. Do not obstruct the ventilation openings at the top, sides and back of the
system. Keep the fresh air intake at the bottom front side of the chassis completely clear, and
ensure that fresh air supply is not mixed with hot exhaust from other devices.
To ensure proper air flow within the system make sure that all slots are populated with either
filler blades, blades or dummy blades.
Product Damage
High humidity and condensation on blade surfaces causes short circuits.
Do not operate the system outside the specified environmental limits. Make sure the system is
completely dry and there is no moisture on any surface before applying power. Do not start the
system below 0ºC.
Injury
Caution: this unit has four -48V to -60 V DC feeders. All must be disconnected to de-energize
the system. To reduce the risk of injury, disconnect the feeders when removing power from the
system.
System Damage
Air Filter
Air contamination can pollute the air filter and obstruct the air intake of the system which may
cause system overheating and component damage.
To guarantee proper airflow through the system the air filter has to be replaced at least every
six months. Artesyn Embedded Technologies - Embedded Computing recommends to
replace the air filter every 90 days. Filter replacement frequency depends on the environment
the system is subjected to.
Air filters should be cleaned at least every 90 days or sooner, depending on the conditions of
the environment. Because central offices vary in physical location and cleanliness, check your
air filters every week after you first install your system. In a dusty environment, a filter may
