Preparing for installation
Safety recommendations
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
•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.
•Make sure the installation site is reliably grounded, and lightning protection and
ESD-prevention are provided.
•Only trained and qualified personnel are allowed to install or service the router.
•Keep accessories, installation tools, and documentation safe.
•Avoid bodily injury. Do not touch any power plug when it is connected.
•Clean up the packaging materials after installation to avoid fire hazard.
Electricity
•Locate the emergency power-off switch in the room before installation. Shut the power off at
once in case accident occurs.
•Make sure the router has been correctly grounded.
•Use an uninterrupted power supply (UPS).
•If there are two power inputs, disconnect the two power inputs to power off the router.
•Do not work alone when the router has power.
•Always verify that the power has been disconnected.
Laser safety
The H3C SR6602-X routers are Class 1 laser devices.
WARNING!
•Do not stare into any fiber port when the router has power. The laser light emitted from the optical
fiber may hurt your eyes.
•Use a fiber test equipment, rather than a microscope or magnifier to observe an operating fiber o
r
port when you test link connectivity or system parameters.

2
Router moving
When you move an SR6602-X router, follow these guidelines:
•Move and unpack the router carefully to avoid router damage.
•Use a safety hand truck when you move a heavy device or multiple devices.
•Before you move the router, remove all the cables, USB devices, mounting brackets, and cable
management brackets.
•If the router needs to be moved over a long distance, remove all the field-replaceable units
(FRUs), such as power modules, fan trays, and interface modules, and package them
separately, and install the filler panels supplied with router.
•If the router needs to be moved over a short distance, make sure all the FRUs are securely
seated in slot and the screws are fastened.
•When you move or lift the router chassis, support the bottom of the chassis, rather than holding
any FRU. Make sure the accessories of the router are not lost or damaged during router
moving.
Examining the installation site
Weight support
Evaluate the floor loading as compared to the actual weight of the router and its accessories (such as
rack and power modules), and make sure the floor can support the weight of the rack and the router
chassis. For more information, see “Appendix A Chassis views and technical specifications.”
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 router.
For the temperature and humidity requirements of the router, see Table 1.

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.

Figure 1 Airflow (SR6602-X1)
•Make sure there is enough space (greater than 10 cm (3.94 in)) around the air intake and outlet
vents on the router for good ventilation.
•Make sure the installation site has a good cooling system.
ESD prevention
CAUTION:
•Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the
range of 1 to 10 megohm (Mohm) between human body and the ground.
•The SR6602-X does not provide any ESD wrist strap. Prepare it yourself.
To prevent electrostatic discharge (ESD), note the following guidelines:
•Make sure the router and rack are well grounded.
•An anti-static floor is installed and well grounded.
•Maintain the humidity and temperature at a proper level in the equipment room. For more
information, see “Temperature and humidity.”
•Always wear an ESD wrist strap and ESD cloth when touching a circuit board, interface module,
or transceiver module.
•Place the removed memory module, CF card, FIP, HIM, or MIM on an antistatic workbench, with
the face upward, or put it into an antistatic bag.
•Touch only the edges, instead of electronic components when observing or moving a removed
memory module, CF card, HIM, or MIM.
To use the ESD wrist strap, perform the following steps:
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. Attach the ESD wrist strap to the alligator clips.
4. Attach the alligator clips to the rack post.
5. Make sure the rack is well grounded.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch 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 switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Lightning protection
To protect the router from lightning better, do as follows:
•Make sure the chassis is well grounded.
•Make sure the grounding terminal of the AC power receptacle is well grounded.
Space
For easy installation and maintenance, follow these space requirements:
•Reserve a minimum of 1 m (3.28 ft) of clearance between the rack and walls or other devices.

6
•For heat dissipation, make sure the headroom in the equipment room is no less than 3 m (9.84
ft).
•Make sure the rack has enough space to accommodate the switch. See Table 6 for rack
requirements. For more information about chassis dimensions, see "Appendix A Chassis views
and technical specifications."

As a best practice, use a rack a
minimum of 0.8 m (2.62 ft) in depth.
NOTE:
The signal cables and power cords are routed through the front of the chassis. If you use power
cords that has a conductor cross-section area of a minimum of 16 sq mm (0.02 sq in), leave more
space between the front rack posts and the front door as appropriate.
Power supply
Perform the following steps to satisfy the power supply requirements of the SR6602-X routers:
1. Calculate the system power consumption.
The system power consumption of the SR6602-X routers depends on the number and type of
interface modules, and fan tray power consumption. For the power consumption of the router,
see “Appendix A Chassis views and technical specifications.”
2. Select power modules according to the system power consumption.
To ensure normal operation of the router, make sure the maximum output power of the power
modules is greater than the system power consumption of the router. After determining the
system power consumption, you can select power modules as needed. For power module
specifications, see “Appendix A Chassis views and technical specifications.”
3. Verify that the power source on the installation site satisfies the power input of the power
modules.
Make sure the power source of the installation site is steady and can satisfy the input
requirements of the power modules and parameters such as rated voltage.
