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 the 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.
Laser safety
The firewall is a Class 1 laser device.
WARNING!
Do not stare into any fiber port when the firewall has power. The laser light emitted from the optical fiber
might hurt your eyes.
• Before you disconnect the fiber connector, execute the shutdown command in interface view to
disable the optical source.
• Install the dust covers to the optical fiber connector to avoid connector damage by built-up dust.
Handling safety
When you move the firewall, follow these guidelines:
• Move and unpack the firewall carefully to avoid firewall damage.
• To prevent condensation and even damage to the firewall, unpack the firewall at least half an hour
and power on the firewall at least two hours after you move the firewall from a place below 0°C
(32°F) to the equipment room.
• Use a safety hand truck when you move multiple firewalls.
• Before you move the firewall, remove all cables and mounting brackets.
• If the firewall needs to be moved over a long distance, remove all the field-replaceable units (FRUs),
such as power modules and interface cards, and package them separately, and install the filler
panels supplied with the firewall.
• If the firewall needs to be moved over a short distance, make sure all the FRUs are securely seated
in slot and the screws are fastened.
