Description
Keep the device from humidity, rains, and wet floor.
•
When stacking devices, place the heavier and larger ones at the bottom. Make sure the devices
are stacked evenly.
•
Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the
firewall free of obstruction.
•
Make sure the operating voltage is in the required range.
•
Use a screwdriver, rather than your fingers, to fasten screws.
•
Take away the packaging materials and installation tools after installation.
Electrical safety
•
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
•
Locate the emergency power-off switch in the room before installation. Shut power off at once in
case accident occurs.
•
Do not work alone when the firewall has power.
•
Always verify that the power has been disconnected when you perform operations that require
the device to be powered off.
Handling safety
When you move the firewall, follow these guidelines:
•
Move and unpack the firewall carefully to avoid firewall damage.
•
Unpack the firewall at least half an hour and power on the firewall at least two hours after you
move it from a place below 0°C (32°F) to the equipment room. This prevents condensation and
even damage to the firewall.
•
Before you move the firewall, remove all cables and mounting brackets.
•
For long-distance transportation, remove all removable components, such as 4G modules and
4G antennas, and package them separately, and install the filler panels supplied with the
firewall. For short-distance transportation, make sure all removable components are securely
seated in the slots and the screws are fastened.
•
When you move or lift the firewall chassis, support the bottom of the chassis, rather than
holding any removable component.
•
Make sure the accessories of the firewall are not lost or damaged during firewall moving.
Examining the installation site
The firewall can only be used indoors. To make sure the firewall operates correctly and to prolong its
service lifetime, the installation site must meet the following requirements.
Weight support
Make sure the floor can support the total weight of the chassis and accessories. For the chassis
weight, see "Dimensions and weights."
