Emi; Lightning Protection; Rack-Mounting; Installation Tools - HP A-F1000-E Installation Manual

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the firewall and application
system, adversely affect the firewall in a conduction pattern of capacitance coupling, inductance
coupling, electromagnetic wave radiation, or common impedance (including grounding system)
coupling. To prevent EMI, note the following guidelines:
Take measures against interference from the power grid.
•
• Do not use the firewall together with the grounding equipment or light-prevention equipment of
power equipment, and keep the firewall far away from them.
Keep the firewall far away from high-power radio launchers, radars, and equipment with high
•
frequency or high current.
NOTE:
Use electromagnetic shielding when necessary.

Lightning protection

To protect the firewall from lightning better, do as follows:
• Make sure the grounding cable of the chassis is well grounded.
Make sure the grounding terminal of the AC power receptacle is well grounded.
•
Install a lightning arrester at the input end of the power supply to enhance the lightning protection
•
capability of the power supply.

Rack-mounting

Before mounting the firewall in a standard 19-inch rack, adhere to the following requirements:
The rack is sturdy enough to support the firewall and installation accessories.
•
Make sure that the size of the rack is appropriate for the firewall, and that there is enough clearance
•
around the left and right sides of the firewall for heat dissipation.
For heat dissipation and device maintenance, make sure the front and rear of the rack should be at
•
least 0.8 m (2.62 ft) away from walls or other devices, and that the headroom in the equipment
room should be no less than 3 m (9.84 ft).
