1 Preparing for installation

Safety recommendations

To avoid bodily injury and damage to the router, read all safety recommendations including the

compliance and safety manual for the router 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.

•

Ensure good ventilation in the equipment room and keep the air inlet and outlet vents of the

router free of obstruction.

•

Make sure the operating voltage is in the required range.

•

When servicing the router, do not wear loose clothing or any other things that could get caught

in the chassis and remove all metal jewelry such as watches, bracelets, and necklaces.

•

Wear protective gloves when inspecting or moving the router.

•

Use a screwdriver to fasten screws.

•

If you cannot install a removable component smoothly, stop your operations and troubleshoot

the issues, preventing component damages caused by misoperations.

•

After completing the installation, move the empty packaging materials and installation tools

away from the router.

•

Keep the chassis and installation tools away from walk areas.

Electricity safety

•

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

cables, missing safety grounds, and wet floors.

•

Locate the emergency power-off switch in the room before installation so you can quickly shut

power off when an electrical accident occurs.

•

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

•

Do not work alone when servicing the router with power present.

•

Never assume that power has been disconnected from a circuit. Always check.

•

The router uses two power switches to achieve redundancy. The router is powered off only

when both power switches are off.

ESD prevention

CAUTION:

Make sure t

he resistance reading between human body and the ground is in the range of 1 to 10

megohms (Mohms).

1-2

Preventing electrostatic discharge

To prevent electrostatic discharge (ESD) damage, follow these guidelines:

•

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

•

Always wear an ESD clothing, an ESD wrist strap, and ESD gloves when installing or removing

removable components. Make sure the wrist strap is reliably grounded.

•

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

•

Put a module in an antistatic bag and keep it secure if you are not to install it in the chassis.

Attaching an ESD wrist strap

1. Put the wrist band of the ESD wrist strap on your wrist.

2. Lock the wrist band tight around your wrist so that it makes good contact with the skin.

3. Attach the other end of the ESD wrist strap to an ESD jack on the chassis.

The router has one ESD jack on both the front and rear panel.

4. Make sure the rack and router is reliably grounded.

Laser safety

WARNING

•

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.

•

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

command in interface view to shut down the port.

CAUTION:

•

Insert dust caps into open optical fiber connectors to protect them from contamination and ESD

damage.

•

Insert dust plugs into open fiber ports and transceiver module ports to protect them from

contamination and ESD damage.

Moving safety

WARNING

Hold the chassis handles firmly to move the router.

CAUTION:

Do not hold air vents of the chassis or the handle of a fan tray, power supply, or module to move the

router. Doing so might cause equipment damage.

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

•

Before unpacking the router, use a mechanical device such as a forklift to move the router as a

best practice. After unpacking the router, use the dolly provided with the router to move the

router to the installation location.

•

Remove all power supplies, modules, and external cables (including power cords) before

moving the chassis.

•

To move the chassis manually, you need four to five people. Before moving the router, remove

modules, filler panels, and fan trays from the router.

•

Lift and put down the chassis slowly and never move it suddenly.

1-3

•

When moving the router, keep your footing solid and maintain body balance.

•

Pay attention to the safety symbols on the package and handle the router accordingly. (The

symbols in Table1-1 are for illustration only. The symbols on your device packages might differ

from these ones.)

Table1-1 Packing symbols

Symbol Description

Do not stack the devices beyond the specified number (n)

Place the device with the arrows up.

The device is fragile. Handle it with care.

Keep the device from humidity, rains, and wet floor.

Ladder safety

The router is 41U high. When you use a ladder to install and maintain the router, follow these

guidelines:

•

Make sure the ladder is in good working condition and the length of the ladder meets the actual

requirements.

•

Use the ladder within its Duty Rating and do not overload it.

•

When using the ladder, secure the ladder and strictly follow the rules for using the ladder to

avoid bodily injury.

Examining the installation site

The router must be used indoors. To ensure correct operation and long service life of the router,

verify that the installation site meets the generic operating environment requirements and all the

requirements in this section before installing the router. For the generic operating environment

requirements, see Generic Operating Environment Requirements for H3C Devices Installed Indoors.

Weight support

Make sure the floor or ground at the installation site can support the combined weight of the router

and the rack. The total weight of the router includes the chassis and its components (for example,

modules, fan trays, power supplies, and cables) and accessories. For the weights of the router and

its components, see H3C CR19000-20 Core Router Hardware Information and Specifications.

To mount the router in a rack, select slide rails that can support the total weight of the router.

To assess the load-bearing requirements for the floor and slide rails, take potential system expansion

(for example, adding more modules, power supplies, and fan trays) also in consideration.

1-4

Space

IMPORTANT:

•

There is a minimum clear height of 3 m (9.84 ft) (from the beam or the air duct to the floor) in

the

equipment room.

•

For easy installation and maintenance, reserve a minimum clearance of 1200 mm (47.24 in)

between the rack and walls or other devices.

Table1-2 Router dimensions and rack requirements

Model Chassis dimensions Rack requirements

CR19000-20

•Height—1820 mm (71.65 in)/41

•Width—440 mm (17.32 in)

•Depth—980 mm (38.58 in)

Chassis—850 mm (33.46 in)

Cable management

bracket—90 mm (3.54 in)

Fan tray handle at the

rear—40 mm (1.57 in)

As a best practice, use a rack that meets the

following requirements:

•With dimensions (H × W × D) of 2200 ×

600 × 1200 mm (86.61 × 23.62 × 47.24 in)

•180 mm (7.09 in) from the front rack posts

to the interior side of the front door when

the router is fully configured with

components and cables. You can reduce

the distance between the front rack posts

and the front door as required.

•A minimum of 950 mm (37.40 in) from the

front rack posts to the interior side of the

rear door.

•740 mm (29.13 in) from the front rack

posts to the rear rack posts.
