Safety With Firewall Moving; Examining The Installation Site; Temperature And Humidity - HP A-F5000 Installation Manual

Safety with firewall moving

When moving an A-F5000 firewall, note the following guidelines:
When moving the firewall, hold the handles at both sides of the chassis.
•
Use at least two persons to move the firewall.
•
Move the firewall carefully.
•
CAUTION:
Do not hold the handle of the fan tray or power supply, the handle of the rear cover of the chassis, or the
air vents of chassis. Any attempt to carry the firewall with these parts may cause equipment damage or
even bodily injury.

Examining the installation site

The A-F5000 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.
