• For better heat dissipation, when installing the EA5801E in the network cabinet, avoid the
short circuit of airflow inside the EA5801E and maximize the vent area.
• If the network cabinet is installed outdoors or in a corridor that is exposed to rain, the
network cabinet must meet the requirements of IP55 class protection. ("IP" refers to
International Protection. The first number "5" refers to the class for preventing the solid
particle from entering the device. That is, the network cabinet cannot completely prevent
dust from entering the device, but the amount of dust that enters the network cabinet
does not damage the device. The second number "5" refers to the class for preventing
water from entering the network cabinet. That is, the water sprayed from different
directions to the network cabinet does not damage the device.)
• If the network cabinet is installed indoors or in a corridor that is out of rain, the network
cabinet must meet the requirements of IP31 class protection. (The first number "3" means
the solid particle with a diameter equal to or larger than 2.5 mm can be prevented from
entering the cabinet. The second number "1" means the drips fallen vertically cannot
damage the device.)
The modes of installing the EA5801E in the outdoor cabinet or network cabinet vary with the
specifications for the customer. The following section describes the common modes to be
taken for installing the EA5801E in the outdoor cabinet or network cabinet.
EA5801E horizontally installed (with the
panel facing the front)

To avoid dusts accumulating on the
board or the board dropping off, do not
install the EA5801E vertically in the
network cabinet, regardless of the front
panel facing upward or downward.
