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
•Keep the router and installation tools away from walk areas.
•Place the router in a dry and flat location and make sure anti-slip measures are in place.
•Remove all external cables and power cords before moving the router.
Electricity safety
•Locate the power-off switch in the equipment room before installation. Shut off the power
immediately if an accident occurs. Disconnect the power cord from the router if necessary.
•Make sure the router is reliably grounded.
•Do not remove and install the chassis cover when the router is operating.
•Connect the interface cables correctly.
•Use an uninterrupted power supply (UPS).
•If two power inputs are available, disconnect both power inputs to power off the router.
•Do not work alone when the router has power.
•Always make sure the power has been disconnected during the installation or replacement
procedure.
Laser safety
•Do not stare into any open apertures of operating transceiver modules or optical fiber
connectors. The laser light emitted from these apertures might hurt your eyes.
•Insert a dust plug into any open fiber port to protect them from contamination or ESD damage.
Examining the installation site
The router can only be used indoors. To ensure correct operation and a long lifespan for your router,
install it in an environment that meets the requirements described in the following subsections.

2
Temperature and humidity
Maintain the temperature and humidity in the equipment room as described in Table 1.
•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 cause problems
including loose mounting screws and circuit failure.
•High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the router.
Table 1 Temperature and humidity requirements
Temperature Relative humidity
–20°C to +60°C (–4°F to +140°F) 5% to 90%, 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.
Table 2 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m3)
Dust particles
≤3 x 104
(No visible dust on the tabletop in three days)
NOTE:
Dust 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 3.
Table 3 Harmful gas limits in an equipment room
Gas Maximum concentration (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
Cooling system
The router uses left-to-right airflow for heat dissipation, as shown in Figure 1.

3
Figure 1 Airflow through the chassis
To ensure good ventilation, follow these guidelines:
•Maintain a minimum clearance of 10 cm (3.94 in) around the air inlet and outlet vents.
•Make sure the installation site has a good ventilation system.
ESD prevention
WARNING!
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 a human body and the ground.
To prevent electrostatic discharge (ESD), follow these guidelines:
•Make sure the router and the floor are reliably grounded.
•Take dust-proof measures for the equipment room.
•Maintain the humidity and temperature levels in the acceptable range.
•Always wear an ESD wrist strap and an ESD garment when touching a circuit board or
transceiver module.
The router does not provide an ESD wrist strap, prepare it yourself.
•Place the removed interface module on an antistatic workbench with the circuit board upward,
or put it in an antistatic bag.
•Touch only the edges instead of electronic components on the circuit board when you observe
or move a removed interface module.
To attach an ESD wrist strap:
1. Wear the wrist strap on your wrist.
2. Lock the wrist strap tight around your wrist to maintain good contact with the skin.
3. Secure the wrist strap lock and the alligator clip lock together.
4. Attach the alligator clip to the grounding screw on the rack in which the router is mounted.
EMI prevention
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.

4
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 router 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 enhance lightning protection for the router, follow these guidelines:
•Make sure the router is reliably grounded.
•Make sure the AC power outlet is reliably grounded.
•Install a lightning protector at the power input end.
Rack requirements
To install the router in a rack, make sure the rack meets the following requirements:
•The rack has a good ventilation system.
•The rack is sturdy and can support the router and its accessories.
•The rack has a size that can accommodate the router.
•Enough clearances are reserved at the two sides of the router for heat dissipation.
•A minimum of 0.8 m (2.62 ft) of clearance is reserved between the rack and walls or other
devices for heat dissipation and maintenance.
•The headroom in the equipment room is not less than 3 m (9.84 ft).

chassis.
2. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding
hole.
3. Remove the hex nut from a grounding post on a grounding strip.
4. Use needle-nose pliers to bend a hook at the other end of the grounding cable. Attach the hook
to the grounding post and use the hex nut to secure the hook to the post.
Figure 13 Grounding the router with a grounding strip
Grounding the router through the grounding terminal on the
rack
Make sure the rack is reliably grounded before grounding the router.
To ground the router through the grounding terminal on the rack:
