Safety With Laser; Examining The Installation Site; Temperature And Humidity - HP A-F1000-E Installation Manual

If there are two power inputs, disconnect the two power inputs to power off the firewall.
•
• Do not work alone when the firewall has power.
Always check that the power has been disconnected.
•

Safety with laser

• Do not stare into the optical port or fiber connector because the laser light emitted from the optical
fiber may hurt your eyes.
Install a dust plug on the transceiver module to avoid damage to the transceiver module.

Examining the installation site

The HP A-F1000-E firewall can only be used indoors. To ensure that the firewall works properly and to
prolong its service lifetime, the installation site must meet the following requirements:

Temperature and humidity

•
Altitude
•
Cleanness
•
Cooling system
•
• ESD prevention
EMI
•
Lightning protection
•
Rack-mounting
•
Temperature and humidity
You must maintain a proper temperature and humidity in the equipment room. Long-term high humidity
may lead to bad insulation, electricity leakage, mechanical property changes, and metal corrosion.
However, if the humidity is too low, captive screws may become loose as the result of contraction of
insulation washers and static electricity may be produced in a dry environment to jeopardize the circuits
on the device. A high temperature is the most undesirable condition, because it accelerates the aging of
insulation materials and significantly lowers reliability and service life of the firewall.
