Safety recommendations
To avoid any equipment damage or bodily injury, read the following safety recommendations before
installation. Note that the recommendations do not cover every possible hazardous condition.
Safety symbols
When reading this document, note the following symbols:
WARNING means an alert that calls attention to important information that if not understood or
followed can result in personal injury.
CAUTION means an alert that calls attention to important information that if not understood or
followed can result in data loss, data corruption, or damage to hardware or software.
General safety recommendations
•
Do not place the firewall on an unstable case or desk. The firewall might be severely damaged
in case of a fall.
•
Make sure the ground is dry and flat and anti-slip measures are in place.
•
Keep the chassis and installation tools away from walk areas.
•
Keep the chassis clean and dust-free.
•
Do not place the firewall near water or in a damp environment. Prevent water or moisture from
entering the firewall chassis.
•
Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the
firewall free of obstruction.
•
Make sure the operating voltage is in the required range.
•
Use a screwdriver, rather than your fingers, to fasten screws.
•
Stack devices according to the sizes of and packing symbols on the packages.

Electrical safety
•
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
•
Locate the emergency power-off switch in the room before installation. Shut the power off at
once in case accident occurs.
•
Do not work alone when the firewall has power.
•
Always verify that the power has been disconnected.
Laser safety
WARNING
!
Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into
beams or view directly with optical instruments when the firewall is operating.
The firewall is a Class 1 laser device.
•
Before you disconnect the fiber connector, execute the shutdown command in interface view
to disable the optical source.
•
Install dust caps to disconnected optical fiber connectors and ports on disconnected transceiver
modules to avoid damage caused by built-up dust.
•
Insert a dust plug into empty fiber ports.
Handling safety
When you move the firewall, follow these guidelines:
•
Move and unpack the firewall carefully to avoid firewall damage.
•
Unpack the firewall at least half an hour and power on the firewall at least two hours after you
move it from a place below 0°C (32°F) to the equipment room. This prevents condensation and
even damage to the firewall.
•
Use a safety hand truck when you move multiple firewalls.

3
•
Before you move the firewall, remove all cables and mounting brackets.
•
For long-distance transportation, remove all removable components, such as power modules
and interface modules, and package them separately, and install the filler panels supplied with
the firewall. For short-distance transportation, make sure all removable components are
securely seated in the slots and the screws are fastened.
•
When you move or lift the firewall chassis, support the bottom of the chassis, rather than
holding any removable component. Make sure the accessories of the firewall are not lost or
damaged during firewall moving.
Examining the installation site
The firewall can only be used indoors. To make sure the firewall operates correctly and to prolong its
service lifetime, the installation site must meet the following requirements.
Weight support
Make sure the floor can support the total weight of the rack, chassis, modules, and all other
components. For more information, see "Dimensions and weights."
Temperature and humidity
Maintain appropriate temperature and humidity in the equipment room.
•
Lasting high relative humidity can cause poor insulation, electricity leakage, 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 Table1-1.
Table1-1 Temperature/humidity requirements
Temperature
Relative humidity
•Operating:
Without drives: 0°C to 45°C (32°F
to 113°F)
With hard drives: 5°C to 40°C
(41°F to 104°F)
•Storage: –40°C to +70°C (–40°F to
+158°F)
•Operating:
Without drives: 5% to 95%, noncondensing
With drives: 10% to 90%, noncondensing
•Storage: 5% to 95%, noncondensing
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion
and premature aging of components, as shown in Table1-3.

Cooling system
For adequate cooling of the firewall, follow these guidelines:
•
Install the firewall at the installation site with its airflow direction meeting the ventilation
requirements.
Workbench mounting—Ensure a minimum clearance of 100 mm (3.94 in) around the air
inlet and outlet vents of the chassis.
19-inch rack mounting—Ensure a minimum clearance of 80 mm (3.15 in) around the air
inlet and outlet vents of the chassis and a distance of 1U (44.45 mm, or 1.75 in) between the
chassis and other devices.
•
Make sure the installation site has a good cooling system.
The F1005 and F1010 firewalls use passive cooling for heat dissipation.
The F1020, F1030, F1050, F1060, F1070, F1080, and F1090 firewalls provide left side-intake and
right-side exhaust airflow for heat dissipation.
Figure1-2 Airflow through the F1080 firewall chassis
ESD prevention
To prevent electrostatic discharge (ESD), follow these guidelines:
•
Make sure the firewall, the workbench, and the rack are reliably grounded.
•
Take dust-proof measures for the equipment room. For more information, see "Cleanliness."

5
•
Maintain the humidity and temperature at an acceptable level. For more information, see
"Temperature and humidity."
•
Put the removed interface modules away on an ESD workbench, with the PCB upward, or put
them in ESD bags for future use.
•
Always wear ESD clothing, ESD gloves, and an ESD wrist strap.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the firewall and application
system, adversely affect the firewall in the following ways:
•
A conduction pattern of capacitance coupling.
•
Inductance coupling.
•
Electromagnetic wave radiation.
•
Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
•
If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
•
Keep the firewall far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
•
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors. If part of the network cable of an Ethernet port must
be routed outdoors, connect a lightning arrester to the cable before you plug the cable into the
port.
Lightning protection
To protect the firewall from lightning better, follow these guidelines:
•
Make sure the grounding cable of the chassis is reliably grounded.
•
Make sure the grounding terminal of the AC power receptacle is reliably grounded.
•
If an AC power cord is routed from outdoors for connecting to the device, connect the power
cord first to a power lightning arrester before connecting it to the power receptacle on the
device.
•
If a network cable is routed from outdoors for connecting to an Ethernet port on the firewall,

Step
Description
1. Start Before installation, make sure all requirements on the checklist
are met and the firewall is powered off.
2. Mounting the firewall on a
workbench Verify that the workbench is sturdy and reliably grounded.
Ensure a minimum clearance of100 mm (3.94 in) around the air
inlet and outlet vents of the chassis.
3. Installing the firewall in a standard
19-inch rack To avoid bodily injury and device damage, use a minimum of
two people to rack-mount the device.
4. Grounding the firewall Before installation, make sure the firewall and rack are reliably
grounded and you wear an ESD wrist strap.
5. Installing power modules Before you install a power module, make sure the power
module
is not connected to anypower source and the grounding
cable of the firewall is connected reliably.
6. Installing an interface module Install compatible interface modules on the firewall.
7. Installing a drive Install compatible drives on the firewall.
8. Connecting Ethernet cables The firewall provides various ports. Choose compatible
transceiver modules and cables as required. To avoid bodily
injury or device damage, read the restrictions and guidelines
carefully before connection.
9. Connecting power cords Connect compatible power cords to the power modules.
10. Verifying the installation Verify that the firewall is installed securely and reliably
grounded, and that the power modules are as required.
Mounting the firewall on a workbench
IMPORTANT:
•
Ensure good ventilation and a minimum clearance of 100 mm (3.94 in) around the chassis for
heat dissipation.
•
Avoid placing heavy objects on the firewall.
•
To stack firewalls, make sure a minimum vertical distance of 15 mm (0.59 in) is available
between
two adjacent firewalls.

CAUTION:
•
For adequate heat dissipation, ensure a minimum clearance of 80 mm (3.15 in) around the air
inlet and outlet vents of the chassis and a distance of 1U (44.45 mm, or 1.75 in) between the
chassis and other devices in the rack.
•
As a best practice, use a rack shelf together with the mounting brackets
to support the weight of
the chassis.
Rack-mounting the firewall by using front and rear mounting
brackets
The F1020, F1030, F1050, F1060, F1070, F1080, and F1090 firewalls support this installation
