1.4 Checking Installation Conditions

Before starting installation, make sure that the equipment room, power supply, ground wire, optical cables, and other materials are ready When these installation conditions are confirmed, the installation may begin according to the pre-designed layouts

For detailed requirements and related items, refer to Appendix A "Operation Environment Requirements" and Appendix B "Equipment Grounding"

1.5 Unpacking the Cabinet

Purpose This procedure guides you to unpack the cabinet.

Tools /Materials Spanner

Screwdriver Hammer Ejector lever

Prerequisites The cabinet has been delivered to the installation site.

Required/As

Warning

The wooden case is direction-oriented and should not be placed upside down Otherwise, fatal damages would be caused to the product Since the cabinet is rather heavy, erecting the cabinet improperly may cause personal injuries

Caution

During the transportation and handling of products, spare parts or components, make sure to avoid the collision of such things against doors, walls or shelves

Caution

To avoid equipment damage in the course of moving, move the packing box to the equipment room or a place near the equipment room before unpacking

Caution

In the process of transporting, handling and installing the equipment, it is forbidden to reach the uncoated metal surface of equipment parts or components with sweaty or dirty gloves

Caution

When handling the cabinet, both hands should hold on the solid positions such as the base, the upper cable rack or bone frame Do not apply too much force on such positions with poor rigidity as cable support, cable fixing beam, so as to avoid any damage to the cabinet or any accident

Caution

Remove the lining board of the rack at the place where the cabinet is to be

Caution

To protect the equipment and find out the cause, place the unpacked equipment indoor Take photos of the site storage environment, the rusted or corroded equipment/packing box/packaging materials Properly keep these photos and store the packing box/packing materials

Step 2 Move the packing box to the equipment room or a place nearby before unpacking

it

Step 3 Check the outer package Stop unpacking immediately, if there is

 Serious damage to the outer package

 Water on the outside packaging box

 Rust/water on the equipment Find out the cause and feed back the information to the local representative office

Step 4 Insert one end of the ejector lever into the hold for the tongue of the wooden case

cover

Step 5 Turn the ejector lever to straighten the tongue See Figure 1.1 Or use a

screwdriver or a hammer to operate the tongue

Spanner Tongue

Woodenboard Steeledge

Figure 1.1 Straightening the tongues Step 6 After straightening all the tongues on the cover, remove the cover See Figure 1.1

Figure 1.1 Removing the cover Step 7 Straighten all the tongues that join the wooden boards around the wooden case

Step 9 Take the cabinet out of the packing box.

Step 10 Remove the plastic packing of the cabinet and erect the cabinet

 Note

At least three persons are required to erect the cabinet: one person to hold the cabinet bottom, and two persons to lift the top of the cabinet and make the cabinet vertical

Step 11 Compare the equipment inside with the packing list If there are any differences,

notify the local customer service center

End

1.6 Unpacking the Boards

Purpose This procedure guides you to unpack the boards from the

board carton.

Tools /Materials ESD wrist strap or ESD glove

Diagonal pliers Paper knife

Prerequisites The board carton has been delivered to the installation site.

Required/As needed Required if the boards are placed in a separate carton for

shipment (for example, in the case of capacity expansion).

Caution

Each board is packed in both a plastic bag and an ESD bag Keep the bags properly They can be used later for keeping the boards or packing the damaged boards returned for repair

Caution

The ambient temperature and humidity may have an impact on the boards In each ESD-preventive bag there is a small bag of desiccant, which shall not be thrown away

Caution

Wait for at least 30 minutes before unpacking if the board is just moved from a cold, dry place to a warm, damp place Otherwise, the moisture condenses on the board surface and damages the components

Caution

Step 12 Cut the straps with diagonal pliers and use a paper knife to split the tape along the

seam between the cover and the box body See Figure 1.1

Caution

Do not cut too deep into the carton with the paper knife Otherwise, the knife might scratch the articles inside

Strap Carton label

Pressure-sensitive adhesive tape Foam plate

Label on the board box

ESD bag Board

Board box

Board box

Figure 1.1 Board carton

Step 13 Open the carton and check whether the number and type of the boards are

consistent with that marked on the carton label

Step 14 Confirm that there is no evident damage on the board package

Step 15 Wear a securely grounded ESD wrist strap then open the board box and take the

board out of the ESD bag

1 Hold the bottom of the ESD bag with your left hand

2 Take the board out of the bag gently by its front panel with your right hand

3 Do not touch any electronic component on the board surface to avoid damage

4 Keep the bags properly

Step 16 Check whether any board is physically damaged If any board damage is found,

contact Huawei If not, put the board back into the board box and put the box in the place specified by the customer

 If you are going to install the board right after unpacking, place the board on

an antistatic surface to discharge the static electricity

original materials and place them at a cool dry place without direct sunshine

or strong electromagnetic radiation
