CAUTION:

• Check the resistance of the ESD-preventive wrist strap for safety. The resistance readin

should be in the

range of 1 to 10 megohm (Mohm) between human body and the ground.

• No ESD-preventive wrist strap is provided with the A-F1000-A-EI/A-F1000-S-EI firewall. Prepare it

yourself.

EMI

To prevent electromagnetic interference (EMI) when you use the firewall, 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).
