1 Preparing for installation
Safety recommendations
To avoid bodily injury and damage to the router, read all safety recommendations carefully 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
•
Keep the chassis clean and dust-free.
•
Do not place the router on a moist area, and avoid liquid flowing into the router.
•
Make sure the ground is dry and flat and anti-slip measures are in place.
•
Ensure good ventilation in the equipment room and keep the air inlet and outlet vents of the
router free of obstruction.
•
Use a screwdriver to fasten screws.
•
After completing the installation, move the empty packaging materials and installation tools
away from the router area.
•
Keep the chassis and installation tools away from walk areas.
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.
•
Do not work alone when the router has power.
•
Never assume that power has been disconnected from a circuit. Always check.
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.

1-2
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.
Temperature and humidity
CAUTION:
The operating temperature
range of 50G or 100G transceiver modules is 0°C to 70°C (32°F to
158°F)
. With a 50G or 100G transceiver module installed in the router, the operating temperature
range of the
router is 0°C to 70°C (32°F to 158°F). For information about the models of the 50G or
100G transceiver modules, see H3C RA5300 Router Interface Module Manual.
To ensure correct operation and long lifespan of the router, make sure the temperature and humidity
in the equipment room meet the requirements as described in Table1-1.
•
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 cause washer contraction and ESD and cause
problems including loose mounting screws and circuit failure.
•
A high temperature is the most undesirable condition, because it accelerates the aging of
insulation materials and significantly lowers reliability and service life of the router.
Table1-1 Temperature and humidity requirements
Item Operating Storage
Temperature –20°C to +60°C (–4°F to +140°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
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.
Table1-2 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m3)
Dust particles ≤ 3 × 10

(No visible dust on desk in three days)
NOTE:
Dust particle diameter ≥ 5 µm

1-3
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table1-3.

Gas Max. (mg/m3)
SO21.0
H2S 0.5

Cooling system
The router uses left-to-right airflow for heat dissipation, as shown in Figure1-1.
For adequate cooling of the router, follow these guidelines:
•
Plan the installation location for the router based on its airflow direction.
•
Ensure a minimum clearance of 100 mm (3.94 in) around the air inlet and outlet vents on the
router.
•
Make sure that the installation site has a good cooling system.
Figure1-1 Airflow through the chassis
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.
For more information about grounding the router, see "Grounding the router."
ESD prevention
CAUTION:
Check the resistance of the ESD wrist strap for safety. The resistance reading
must
be in the range
of 1 to 10 megohm (Mohm) between human body and the ground.

1-4
Preventing electrostatic discharge
To prevent electrostatic discharge (ESD) damage, follow these guidelines:
•
Make sure the router, workbench, and rack are reliably grounded.
•
Take dust-proof measures for the equipment room.
•
Maintain the humidity and temperature at acceptable levels.
•
Always wear an ESD wrist strap and make sure it is reliably grounded when installing FRUs.
•
Place the removed interface module on an antistatic workbench or put it into an antistatic bag,
with the component side facing upward.
•
Hold an interface module by its edges when you observe or move a removed interface module.
Do not touch any electronic components.
Attaching an ESD wrist strap
1. Wear the wrist strap on your wrist.
2. Lock the wrist strap tight around your wrist to keep good contact with the skin.
3. Secure the wrist strap lock and the alligator clip lock together.
4. Attach the alligator clip to the rack or workbench.
5. Make sure the rack or workbench is reliably grounded.
EMI
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 high-power transmitting stations and radar stations as well as
high-frequency high-power devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Lightning protection
To better protect the router from lightning, do as follows:
•
Make sure the chassis is reliably grounded.
•
Make sure the grounding terminal of the power receptacle is reliably grounded.
•
Install a lightning arrester at the input end of the power supply to enhance the lightning
protection capability of the power supply.
Power supply
Make sure the power supply system at the installation site is stable and meets the requirements of
the power supplies, including the rated input voltage and input current. For more information about
available power supplies, see H3C RA5300 Router Hardware Information and Specifications.

Grounding the router
CAUTION:
•
Correctly connecting the grounding cable is crucial to lightning protection and EMI protection.
Before using the router, make sure the router is reliably grounded.
•
Connect the grounding cable to the grounding system in the equipment room. Do not connect it
to a fire main or lightning rod.
The router has two grounding points: one on the chassis and one on the left 19-inch rack mounting
bracket. Select a grounding point as required.
Grounding the router through the grounding point on the left
mounting bracket
IMPORTANT:
You can use the grounding point on the left mounting bracket only when the mounting brackets are
installed at the front of the chassis.
To ground the router through the grounding point on the left mounting bracket:
1. Remove the grounding screw from the grounding point on the router chassis.
2. Use the grounding screw to attach the ring terminal (M6) of the grounding cable to the
grounding point on the mounting bracket and then fasten the screw.
3. Connect the ring terminal (M8) at the other end of the grounding cable to the grounding point
on the rack.
