Safety Notes

Operation
System Overheating
Cooling Vents
Improper cooling can lead to blade and system damage and may void the manufacturer’s
warranty.
To ensure proper cooling and undisturbed airflow through the system always operate the
system in a horizontal position. Do not obstruct the ventilation openings at the front and rear
of the system. Keep the fresh air intake at the bottom-front side of the chassis completely clear.
Make sure that the fresh air supply is not mixed with hot exhaust from other devices. Make sure
that all slots are populated with either blades, filler 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 0 ºC.
Injury
Caution: this unit has two -48 V to -60 VDC feeds. All must be disconnected to deenergize the
system. To reduce the risk of injury, disconnect the feeds when removing power from the
system.
System Damage
Air Filters
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 filters have to be replaced at least every
six months. Artesyn Embedded Technologies recommends to replace the air filters every 90
days. Filter replacement frequency depends on the environment the system is subjected to.
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, filter replacement may be
required more often than in a cleaner environment. Check the filters frequently until you have
a good idea of how often they must be replaced. Based on your findings, establish a regular
replacement schedule and keep a log to record the date of each filter replacement.
