3.1 Unpacking the Cases and Checking the Items

This describes how to unpack the cases and check the items in the cases for the convenience of

subsequent cabinet installation.

Prerequisite

l Site preparation for the installation is complete.

l The cases that contain the cabinets and components are delivered to the site.

Context

l When carrying or placing the equipment, you should ensure that it does not collide with

doors, walls, shelves, or other objects.

l When transporting or installing the equipment, components, or parts, you should avoid

touching their uncoated metal surfaces with sweaty or dirty gloves.

Procedure

Step 1 Unload the cases.

CAUTION

When unloading the cases, you should place the cases in sequence. Ensure that the labels on thecases face the same direction.

Step 2 Check whether the number of cases on site is the same as is mentioned in the Packing List andwhether the place of delivery is the same as the actual installation place.

If... Then...

The number of cases on site matches that in the Packing List, Go to Step 4.

The number of cases on site does not match that in the Packing List, Go to Step 3.

Step 3 Stop unpacking the cases. Ask the project supervisor to send the Cargo Problems Reportthat issigned by the customer to the local Huawei office within three days.

Step 5 Stop unpacking the cases, find out the causes, and contact the local Huawei office to furtherhandle the problem.

CAUTION

To protect the equipment and find out the causes, perform the following actions: Move the

unpacked equipment indoors for proper storage, take photos of the storage environment, the

rusted or corroded equipment, packing cases, and packing materials. Keep these photos for future

verification. Store the packing cases and materials properly.

Step 6 Unpack the wooden cases.

CAUTION

l Before the unpacking, move the wooden cases into or close to the equipment room if enough

space is available. This prevents damage to the cabinets during the transportation.

l When you unpack the wooden cases, find the one containing the packing list first. Then, you

can find items rapidly according to the names, codes, positions, and quantities in the Packing

List.

l The following description takes the wooden case that contains the cabinet as an example.

The methods of unpacking other types of wooden cases are similar.

1. Place the wooden case on the ground. Ensure that the side with the wooden frame faces the

bottom.

2. Use a wrench, a flat-head screwdriver, or a claw hammer to straighten the tongues on the

four sides of the cover, as shown in Figure 3-1.
