Preparing for installation
H3C SecPath M9000-AI multiservice security gateways include the M9000-AI-E8 gateway and
M9000-AI-E16 gateway.
Safety recommendations
To avoid bodily injury and equipment damage, read all safety recommendations carefully before
installation. Note that the recommendations do not cover every possible hazardous condition.
General safety recommendations
•
Keep the gateway clean and dust-free.
•
Do not place the gateway on a moist area, and avoid liquid flowing into the gateway.
•
Make sure the ground is dry and flat and anti-slip measures are in place.
•
Keep the gateway and installation tools away from walk areas.
•
Do not wear loose clothing, jewelry (for example, necklace) or any other things that could get
caught in the chassis when you install and maintain the gateway.
Electricity safety
•
Clear the work area of possible electricity hazards, such as ungrounded power extension
cables, missing safety grounds, and wet floors.
•
Locate the emergency power-off switch in the room before installation so you can quickly shut
power off when an electrical accident occurs.
•
Unplug all external cables, including power cords, before moving the chassis.
•
Do not work alone when the gateway has power.
•
Always verify that power has been disconnected from a circuit.
Handling safety
When you move the gateway, follow these guidelines:
•
Remove all external cables, including the power cords, before moving the chassis.
•
As a best practice, use a mechanical lift to move the chassis. To move the chassis manually,
use multiple people.
•
Lift and put down the chassis slowly and never move suddenly.
•
Hold the handles of the chassis.
ESD prevention
To prevent the electric component from being damaged by electrostatic discharge (ESD), follow
these guidelines:
•
Ground the gateway correctly.
•
Always wear an ESD wrist strap and make sure it is correctly grounded when installing FRUs.
•
Hold a PCB by its edges. Do not touch any electronic components or printed circuit.

2
•
Put modules away in antistatic bags for future use.
NOTE:
The gateway has an ESD socket at both the front and rear.
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 gateway is operating.
•
Before you remove the optical fiber connector from a fiber port, execute the shutdown
command in interface view to shut down the port.
CAUTION:
•
Insert optical fiber
caps into open optical fiber connectors to protect them from contamination and
ESD damage.
•
Insert dust plugs into open fiber ports and transceiver module ports to protect them from
contamination and ESD damage.
Examining the installation site
The gateway must be used indoors. To ensure the correct operation and long service life of your
gateway, the installation site must meet the requirements in this section.
Weight support
Make sure the floor can support the total weight of the rack, chassis, and accessories. Additionally,
the floor loading plan must also consider system expansion, such as adding more modules. For
more information, see "Appendix B Technical Specifications."
Space
For easy installation and maintenance, make sure the following requirements are met:
•
Make sure the rack has enough space (in height and depth) to accommodate the gateway.
•
The rack allows front and rear access to the gateway.
•
Aminimum clearance of 1.2 m (3.94 ft) is reserved between the rack and walls or other devices.
For more information about the chassis dimensions, see "Appendix B Technical Specifications."

Cooling
The gateway uses front-to-rear airflow for heat dissipation. Plan the installation site for the gateway
based on its airflow direction for adequate ventilation. Make sure the following requirements are met:
•
The installation site has a good cooling system.
•
The rack for the gateway has a good cooling system.
•
Leave a minimum clearance of 300 mm (11.81 in) around the inlet and outlet air vents.

Power
Agood power supply system is essential for correct operation of the gateway. The gateway supports
AC and DC power inputs. Make sure the equipment room meets the following requirements for the
power supply systems.
•
The AC power supply system is stable and reliable and capable of providing power required by
the gateway. Prepare a diesel generator as a backup power source except for the power lines.
•
The DC power supply system is stable and reliable and its output voltage is stable and within
the acceptable range allowed by the gateway.
•
Enough batteries are available to ensure uninterrupted device operation in the event of a power
failure.
For the power supply system to provide power as required by the router:
1. Calculate the system power consumption.
The system power consumption varies by module type and density. For more information about
system power consumption calculation, see "Appendix B Technical Specifications."
2. Select power supplies and identify the number of power supplies.
The total maximum output power of all power supplies must be higher than the system power
consumption. For more information about available power supplies, see "Appendix A FRUs and
Compatibility Matrixes."

5
Lightning protection
To protect the gateway from the lightning, make sure the following requirements are met:
•
The grounding cable for the chassis is correctly grounded.
•
The grounding terminal of the AC power receptacle is correctly 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 the device, connect the network
cable first to a network port lightning arrester before connecting it to the port.
IMPORTANT:
•
No network port lightning arrester or AC power lightning arrester is provided with the device.
Purchase them as required.
•
For the technical specifications and installation instructions for the lightning arresters, see the
documents shipped with them.
Temperature
CAUTION:
If condensation appears on the chassis when you move it to a high
-temperature environment, dry
the chassis before powering it on to avoid short circuits.
If the temperature in the equipment room is too high, too low, or changes dramatically, the device
reliability is reduced and its service lifetime is shortened.
High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the gateway.
To ensure the correct operation of the gateway, make sure the room temperature meets the
requirements in Table 2.
Table 2 Temperature requirements
Temperature Range
Operating temperature 0°C to 45°C (32°F to 113°F)
Storage temperature –40°C to +70°C (–40°F to +158°F)
Humidity
Maintain appropriate humidity in your equipment room, as described in Table 3.
•
Lasting high relative humidity tends to cause poor insulation, electricity leakage, mechanical
property change of materials, and corrosion of metal parts.
•
Lasting low relative humidity is likely to result in loose screws due to washer contraction, and
even electrostatic discharge (ESD), which causes the circuits to fail.
Table 3 Humidity requirements
Humidity Range
Operating humidity 5% RH to 95% RH, noncondensing

6
Humidity Range
Storage humidity 5% RH to 95% RH, noncondensing
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points. In the worst case, electrostatic adsorption can cause
communication failure.
Table 4 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m3)
Dust particles ≤ 3 x 104
(No visible dust on desk in three days)
NOTE:
Dust particle diameter ≥ 5 µm
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 5.

SO21.0
H2S 0.5
NH33.0
Cl20.3
NO21.0
EMI
Electromagnetic interference (EMI) might be coupled from the source to the gateway through the
following coupling mechanisms:
•
Capacitive coupling
•
Inductive coupling
•
Radiative coupling
•
Common impedance coupling
•
Conductive coupling
To prevent EMI, take the following actions:
•
Filter interference from the power grid.
•
Keep the gateway grounding facilities away from grounding and lightning protection facilities of
other devices.
•
Keep the gateway far away from radio transmitting stations, radar stations, and high-frequency
devices to make sure the EMI levels do not exceed the compliant range.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
