power off when an electrical accident occurs.
•
Remove all external cables, including power cords, before moving the chassis.
•
Do not work alone when servicing the router with power present.
•
Never assume that power has been disconnected from a circuit. Always check.
•
The router uses two power switches to achieve redundancy. The router is powered off only
when both power switches are off.
ESD prevention
CAUTION:
Make sure t
he resistance reading between human body and the ground is in the range of 1 to 10
megohms (Mohms).

1-2
Preventing electrostatic discharge
To prevent electrostatic discharge (ESD) damage, follow these guidelines:
•
Ground the router reliably. For how to ground your router, see "Grounding the router."

•
When using the ladder, secure the ladder and strictly follow the rules for using the ladder to
avoid bodily injury.
Examining the installation site
The router must be used indoors. To ensure correct operation and long service life of the router,
verify that the installation site meets the generic operating environment requirements and all the
requirements in this section before installing the router. For the generic operating environment
requirements, see Generic Operating Environment Requirements for H3C Devices Installed Indoors.
Weight support
Make sure the floor or ground at the installation site can support the combined weight of the router
and the rack. The total weight of the router includes the chassis and its components (for example,
modules, fan trays, power supplies, and cables) and accessories. For the weights of the router and
its components, see H3C CR19000-20 Core Router Hardware Information and Specifications.
To mount the router in a rack, select slide rails that can support the total weight of the router.
To assess the load-bearing requirements for the floor and slide rails, take potential system expansion
(for example, adding more modules, power supplies, and fan trays) also in consideration.

1-4
Space
IMPORTANT:
•
There is a minimum clear height of 3 m (9.84 ft) (from the beam or the air duct to the floor) in
the
equipment room.
•
For easy installation and maintenance, reserve a minimum clearance of 1200 mm (47.24 in)
between the rack and walls or other devices.

Figure1-3 Airflow through the chassis
Temperature and humidity
CAUTION:
If condensation
occurs on the chassis when you move it from a lower temperature to a higher
temperature, dry the chassis before powering it on to avoid short circuits.
Adverse temperature and humidity conditions in the equipment room will accelerate the aging of
devices and reduce the capability of the device to withstand harsh environment conditions.
•
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 router.
•
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 screws and circuit failure.
To prevent the preceding issues, maintain the temperature and humidity in the equipment room in
acceptable ranges. As a best practice, maintain the temperature in the range of 18°C to 25°C

1-8
(64.4°F to 77°F) and the relative humidity less than 60% RH for the cold aisle and the air inlet area of
the rack.
Cleanliness
Mechanicallyactive substances 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.
Table1-3 Mechanically active substance concentration limit in the equipment room
Substance Particle diameter Concentration limit
Dust particles ≥ 5 µm ≤ 3 × 104particles/m3
(No visible dust on desk in three days)
Dust (suspension) ≤75 µm ≤0.2 mg/m3
Dust
(sedimentation) 75 µm to 150 µm ≤1.5 mg/(m2h)
Sand 150 µm to 1000 µm ≤30 mg/m3
To maintain cleanliness in the equipment room, follow these guidelines:
•
Use dustproof materials for floors and walls and use coating that does not produce powders.
•
Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips.
Use screen doors and screen windows in the external side.
•
Keep the equipment room clean. If the equipment room environment is not as desired, install air
filters on the rack doors and clean the air filters regularly.
•
Wear ESD clothing and shoe covers before entering the equipment room.
Harmful gas limit
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table1-4.

Gas Maximum concentration (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
NO20.04
To control harmful gases, use the following guidelines:
•
Use environmentally friendly materials to decorate the equipment room. Avoid using materials
that contains harmful gases, such as sulfur or chlorine-containing insulation cottons and rubber
mats.
•
Keep the air inlet of the equipment room away from the pollution source and the sewer.
•
Place batteries separately, preferably in a separate room.

1-9
•
Employ a professional company to monitor and control harmful gases in the equipment room
regularly.

All electromagnetic interference (EMI) sources, from outside or inside of the router and application
system, adversely affect the router 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:
•
Take effective measures to filter interference from the power grid.
•
Separate the working earthing system of the router from the grounding facility and lightning
protection facility of the other electrical devices as far as possible.
•
Keep the router far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Grounding
Correctly grounding the router is crucial to lightning protection, anti-interference, and ESD
prevention. Use a good grounding system for the router. Make sure the resistance between the
chassis and the ground is less than 1 ohm.
Power supply
Agood power supply system is essential for correct operation of the router. The router supports AC,
DC, and high-voltage 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 router. As a best practice, use two power lines for the AC power supply system. If only one
power line is available in the equipment room, prepare a diesel generator as a backup power
source.
•
The DC power supply system is stable and reliable and its output voltage is stable and within
the acceptable range allowed by the device.
•
Enough batteries are available to ensure uninterrupted device operation in the event of a power
failure.
