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.
Moving safety
WARNING
!
Hold the chassis handles firmly to move the router.
CAUTION:
Do not hold
air vents of the chassis, the handle of a fan tray or power supply, or
an ejector lever of a
module to move the router. Doing so might cause equipment damage.
The router is heavy and large. When you move the router, follow these guidelines:
•
Remove all external cables (including power cords), modules, and power supplies before
moving the chassis.

1-2
•
Moving the chassis requires a minimum of four people. As a best practice, use a mechanical lift
to move the chassis.
•
Lift and put down the chassis slowly and never move it suddenly.
•
Pay attention to the safety symbols on the package and handle the router accordingly. (The
symbols in Table1-1 are for illustration only. The symbols on your device packages might differ
from these ones.)
Table1-1 Packing symbols

Place the device with the arrows up.
The device is fragile. Handle it with care.
Keep the device from humidity, rains, and wet floor.
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).
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."
•
Always wear an ESD wrist strap when installing removable components. Make sure the wrist
strap is reliably grounded.
•
Hold a module by its edges. Do not touch any electronic components or PCB.
•
Put a module in an antistatic bag and keep it secure if you are not to install it in the chassis.

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 router 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 dust 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 router must be used indoors. To ensure correct operation and long service life of your router,
make sure the installation site meets the following requirements.
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 and power supplies) and accessories. For the weights of the router and its components,
see "Weights and dimensions."
To mount the switch 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) also in consideration.

1-4
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.
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. For long-term, highly available operation of
the router, make sure temperature and humidity in the equipment room meets the requirements
described in Table1-2.
•
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.
Table1-2 Temperature and humidity requirements
Item Operating Storage
Temperature 0°C to 45°C (32°F to 113°F) –40°C to +70°C (–40°F to +158°F)
Humidity 5% RH to 95% RH, noncondensing 5% RH to 95% RH, noncondensing
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 and clean the air filters of the rack regularly.
•
Wear ESD clothing and shoe covers before entering the equipment room.

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.
