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 chassis and installation tools away from walk areas.

•

Make sure the ground is dry and flat and anti-slip measures are in place.

•

Unplug all the external cables (including power cords) before moving the chassis.

Electricity safety

•

Locate the emergency power-off switch in the room before installation. Shut the power off at

once in case accident occurs. Disconnect the power cord of the router if necessary.

•

Make sure the router is correctly grounded.

•

Do not open or close the chassis cover when the router is powered on.

•

Correctly connect the interface cables of the router.

•

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 make sure the power has been disconnected during the installation and replacement

procedures.

Laser safety

WARNING!

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.

CAUTION:

•

Before you remove the optical fiber connector from a fiber port, execute the shutdown

command

in interface view to shut down the port.

•

Insert a dust cap into any unused optical fiber connector and a dust plug into any unused fiber

port or transceiver module port to protect them from contamination and ESD damage.

Examining the installation site

The routers can only be used indoors. To make sure the router operates correctly and to prolong its

service lifetime, the installation site must meet the following requirements.

Temperature and humidity

Maintain temperature and humidity in the equipment room as described in Table 2.

•

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.

Table 2 Temperature and humidity requirements

Operating temperature

Operating humidity

0°C to 45°C (32°F to 113°F) 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. To ensure correct operation, the

equipment room must meet the dust concentration requirements listed in Table 3.

Table 3 Dust concentration limit in the equipment room

Substance

Concentration limit (particles/m

)

Dust particles ≤ 3 x 104

(No visible dust on desk in three days)

NOTE:

Dust particle diameter ≥ 5 µm

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion

and premature aging of components, as shown in Table 4.

Cooling system

The router uses left to rear airflow for heat dissipation.

Figure 1 Airflow through the MSR 5600 chassis

To ensure good ventilation, the following requirements must be met:

•

Leave a minimum clearance of 10 cm (3.94 in) for the air inlet and outlet vents.

•

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.

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 at acceptable levels.

•

Always wear an ESD wrist strap and ESD cloth when touching a circuit board or transceiver

module.

The router does not supply an ESD wrist wrap. Prepare an ESD wrist wrap yourself.

•

Place the removed memory module, CF card, or interface module on an antistatic workbench,

with the face upward, or put it into an antistatic bag.

•

Touch only the edges, instead of electronic components when you observe or move a removed

memory module, CF card, or 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 keep good contact with the skin.

3. Insert the ESD plug into the ESD socket.

4. Connect the alligator clip to the rack.

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, perform the following tasks:

•

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 to make sure the EMI levels do not exceed the compliant range.

•

Use electromagnetic shielding, for example, shielded interface cables, when necessary.

•

To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning

strikes, only route interface cables indoors. If you must route interface cables outdoors, install

network port lightning protectors.

Lightning protection

The router has its own lightning protection system. To better protect the router from lightning, do as

follows:

•

Make sure the grounding cable of the chassis is reliably grounded.

•

Make sure the grounding terminal of the AC 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.

•

Install a special lightning arrester at the input end of outdoor signal lines (for example, E1/T1

line) to which interface modules of the router are connected to enhance the lightning protection

capability.

Rack-mounting

Before mounting the router in a standard 19-inch rack, adhere to the following requirements:

•

The rack is equipped with a good ventilation system.

•

The rack is sturdy enough to support the router and its accessories.

•

For heat dissipation and device maintenance, make sure the front and rear of the rack are at

least 0.8 m (2.62 ft) away from walls or other devices, and the headroom in the equipment room

is no less than 3 m (9.84 ft).
