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).

• Do not work alone when the router has power.

• Always make sure the power has been disconnected during the installation or replacement

procedure.

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.

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.

2

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.

)

Dust particles

≤ 3 x 10

(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.

Cooling system

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.

3

The router does not provide an ESD wrist strap, prepare it yourself.

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 router.

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.

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.

To mount the router on a workbench:

1. Place the router upside down on the workbench and attach the rubber feet to the four round

holes in the chassis bottom.

Figure 10 Attaching rubber feet to the router

2. Place the router upside up on the workbench. Make sure the rubber feet stand securely on the

workbench.

Figure 11 Mounting the router on a workbench

Installing the router on a wall

CAUTION:

Make sure the port side of the router is on the top and is parallel to the floor.

To install the router on a wall:

1. Determine and mark the locations of the mounting holes on the wall, and drill four 22 mm (0.87

in) diameter holes at the mounting hole locations you marked.

12

Figure 12 Drilling holes in a wall

2. Attach 19-inch rack mounting brackets to both sides of the router.

Grounding the router through the grounding

terminal on the rack

CAUTION:

• Correctly connecting the grounding cable is crucial to lightning protection and EMI protection.

• Ensure a minimum resistance of 5 ohms between the router and the ground.

• Make sure the rack is reliably grounded before grounding the router.

To ground the router through the grounding terminal on the rack:

1. Remove the grounding screw from the grounding hole in the front panel of the 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 the grounding terminal of the rack.

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. See Figure 15.
