WARNING!
•
Do not stare into any fiber port when the firewall has power. The laser light emitted from the optical
fiber may hurt your eyes.
• Use a fiber test equipment, rather than a microscope or magnifier to observe an operating fiber
connector or port when you test link connectivity or system parameters.
Handling safety
When you move a firewall, follow these guidelines:
• Remove all external cables, including the power cords, before moving the chassis.
• When you move multiple firewalls, use a pallet jack.
• Lift and put down the chassis slowly and never move suddenly.
• If the firewall needs to be moved over a long distance, remove all field-replaceable units (FRUs),
such as interface modules, put them separately in anti-static bags, and install the filler panels
supplied with firewall.
• If the firewall needs to be moved over a short distance, make sure all FRUs are securely seated in
slot and the screws are fastened.
• Make sure the accessories of the firewall are not lost or damaged during firewall moving.
Examining the installation site
The firewalls must be used indoors. To ensure normal operation and long service life of your firewall, the
installation site must meet the requirements in this section.
Weight support
Make sure the floor can support the total weight of the rack, chassis, cards, power modules, and all
other components. For more information, see " Dimensions and weight ."
Temperature and humidity
Maintain appropriate temperature and humidity in the equipment room.
• Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property
change of materials, and metal corrosion.
• Lasting low relative humidity can cause washer contraction and ESD and bring problems including
loose captive screws and circuit failure.
• High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the firewall.
For the temperature and humidity requirements of the firewall, see Table 1 .
