Preparing for installation

This chapter describes preparations for installing an SR8800-F router.

Safety recommendations

To avoid possible bodily injury and equipment damage, read the safety recommendations carefully

before installation. Note that the recommendations do not cover every possible hazardous condition.

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.

•

Keep the chassis and installation tools away from walk areas.

•

Do not wear loose clothing, jewelry (for example, necklace), or any other things that could get

caught in the chassis when you install and maintain the router.

Electricity safety

•

Clear the work area of possible hazards, such as ungrounded power extension cables, missing

safety grounds, and wet floors.

•

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

once in case accident occurs.

•

Remove all external cables, including power cords, before moving the chassis.

•

Do not work alone when the router has power.

•

Always verify that the power has been disconnected.

Moving safety

WARNING

•

Hold the chassis handles firmly to move the router.

•

Do not hold the handle of a fan tray or power supply,

air vents, or the handle on the real panel to

move the router. Doing so might cause equipment damage or even bodily injury.

The router is heavy and large. When you move the router, follow these guidelines:

•

Remove all the external cables, including the power cords, before moving the router.

•

Use a minimum of two people to move the router, and use a mechanical lift if necessary.

•

Lift and put down the router slowly.

ESD prevention

To prevent the electric component from being damaged by the electrostatic discharge (ESD), follow

these guidelines:

•

Ground the router correctly. For how to ground your router, see "Grounding the router."

•

Always wear an ESD wrist strap and make sure it is correctly grounded when installing FRUs.

For how to use an ESD wrist strap, see "Attaching an ESD wrist strap."

•

Hold a PCB by its edges. Do not touch any electronic components or printed circuit.

•

Put cards in ESD bags for future use.

Laser safety

WARNING

•

The router is a Class 1 laser product.

•

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.

Examining the installation site

The router must be used indoors. To ensure correct operation of the router and to prolong its service

life, the installation site must meet the requirements in this section.

Weight support

Make sure the floor can support the total weight of the rack, chassis, cards, and power supplies, and

all other components. Additionally, the floor loading plan must cover system expansion, such as

adding more cards.

Temperature

CAUTION:

If condensation appears on the

router when you move it to a high-

temperature environment, dry the

router before powering it on to avoid short circuits.

To ensure the correct operation of the router, make sure the room temperature is in the range of 0°C

to 45°C (32°F to 113°F).

Humidity

Maintain appropriate humidity in your 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.

Table 1 Humidity requirements

Humidity Range

Operating humidity 10% RH to 95% RH, noncondensing

Storage humidity 5% RH to 95% RH, noncondensing

Operating altitude

Table 2 Operating altitude requirements

Item Specifications

Operating altitude ≤4000 m (13123.36 ft) (available altitude)

≤3000 m (9842.52 ft) (certified altitude)

Cleanliness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of

metal components and contact points. In the worst case, electrostatic adsorption can cause

communication failure.

Table 3 Dust concentration limits in the equipment room

Substance Particle diameter Concentration limit

Dust particles ≥ 0.5 µm ≤ 1.8 × 107particles/m3

Corrosive gases can accelerate corrosion and aging of components. Make sure the corrosive gases

in the equipment room do not exceed the concentration limits as shown in Table 4.

Table 4 Corrosive gas concentration limits in the equipment room

Gas Average concentration (mg/m3) Maximum concentration (mg/m3)

SO20.3 1.0

H2S 0.1 0.5

Cl20.1 0.3

HCI 0.1 0.5

HF 0.01 0.03

NH31.0 3.0

O30.05 0.1

NOX0.5 1.0

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the router and application

system, adversely affect the router in the following ways:

•

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

•

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

Grounding

For the operating reliability of your router, follow these guidelines:

•

Use a good grounding system to protect your router against lightning shocks, interferences, and

ESD.

•

Make sure the resistance between the chassis and the ground is less than 1 ohm.

For more information about grounding the routers, see "Grounding the router."

Power

Perform the following tasks to meet the power requirements:

1. Calculate the system power consumption

The system power consumption varies by card type, density, and fan tray power consumption.

For more information about system power consumption calculation, see "Module power

consumption and total power consumption."

2. Select power supplies and determine the number of power supplies.

The total maximum output power of all power supplies must be higher than the system power

consumption. For more information about available power supplies, see "Power supplies."

3. Verify that the power system at the installation site meets the requirements of the power

supplies, including the input method and rated input voltage.

Cooling

The airflow designs for all SR8800-F router models are the same.

For heat dissipation, make sure the following requirements are met:

•

A minimum clearance of 10 cm (3.94 in) is reserved at the inlet air vents and outlet air vents.

•

The rack for the router has a good cooling system.

•

The installation site has a good cooling system.
