3.1 Unpacking the Cases and Checking the Items
This section describes how to unpack the cases and check the items in the cases to facilitate
subsequent cabinet installation.
Prerequisites
lSite preparation for the installation is complete.
lThe cases that contain the cabinets and components are delivered to the site.
Context
lWhen carrying or placing the equipment, you should ensure that it does not collide with
doors, walls, shelves, or other objects.
lWhen 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 the
cases face the same direction.
Step 2 Check whether the number of cases on site matches the Packing List and whether 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 3.
The number of cases on site does not match that in the Packing List Go to Step 4.
Step 3 Check the shockwatch labels on both sides of each case to determine whether each case has been
hit.
If... Then...
Both labels on a case are transparent, as
shown by part 1 in Figure 3-1
The case has not been hit. Go to Step 5.

If... Then...
Any label on a case becomes red, as shown
by part 2 in Figure 3-1
The case has been hit by a force greater than
50g (g is the standard gravity) during
transportation. Such hit damages the cabinet or
boards in the case. To handle this problem, go
to Step 4.
Figure 3-1 Shockwatch label
Step 4 Stop unpacking the cases. Ask the project supervisor to send the Cargo Problems Report that is
signed by the customer to the local Huawei office within three days.
Step 5 Check whether the cases are intact.
If... Then...
Any case is seriously damaged or soaked Go to Step 6.
The cases are intact Go to Step 7.
Step 6 Stop unpacking the cases, find out the causes, and contact the local Huawei office to further
handle 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 7 Unpack the wooden cases.
CAUTION
lBefore 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.
lWhen you unpack the wooden cases, unpack 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.
lThe 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 3-2.
Figure 3-2 Straightening the tongue
3. Remove the cover. If the wooden case contains a carton, take out the carton and then open
it according to Step 8. If the wooden case contains a cabinet, go to the next step. See Figure
3-3.

CAUTION
This operation needs three to five installers. Prevent the cabinet from falling during the
erection to avoid personnel injury.
6. Remove the bottom of the case, that is, the side with the wooden frame.
7. Remove the packing foam from the corners and edges of the cabinet.
8. Remove the vacuum plastic bag.
Step 8 Unpack the carton, as shown in Figure 3-5.
Figure 3-5 Unpacking a carton
1 Carton label 2 Strap 3 Pressure-sensitive tape
4 Foam plate 5 Board label 6 Board
1. Check the types and quantities of the items in the carton according to the carton label.
2. Use diagonal pliers to cut the straps.
3. Rip the tape along the joint seams by using the paper knife. Do not insert the knife too deep,
or else the items may be damaged.
4. Unpack the carton and take out the items.
Step 9 Unpack boards.
CAUTION
lElectronic components are extremely sensitive to static electricity. When unpacking the
boards, wear an ESD wrist strap or a pair of ESD gloves properly.
lThe ESD bag contains desiccant to keep the bag dry. When taking the board from a cold dry
place to a hot damp place, wait at least 30 minutes before unpacking. Otherwise, moisture
condensed on the board surface may damage the board.
1. Check that no evident damage is on the board packages.
2. Open the packages and ensure that the boards are in good condition. For any board problem,
contact the order management engineer at the local Huawei office.

Step 10 Check whether the unpacked boards need to be installed immediately, and then proceed
accordingly.
If... Then...
The unpacked boards need to be installed
immediately
Place the boards on an ESD surface and
discharge the static electricity.
The unpacked boards need not be installed
immediately
Pack the boards with the original materials and
place them in a cool dry place away from direct
sunlight or strong electromagnetic radiation.
Step 11 Check the items. Check the items one by one according to the names, types, and quantities
described in the Packing List.
The acceptance of items covers the following aspects:
lAppearance: Check whether there is any visible defect, looseness, distortion, or damage;
check whether the labels are legible and whether the nameplates and decorating plates are
available and meet the requirements.
lIntegrity: Ensure that all the parts and accessories required for the installation of cabinets are
available.
lComputer: Check whether the monitor, keyboard, and mouse are intact and in good condition.
lBoard: Ensure that the type and quantity of the boards are consistent with those in the Packing
List. Ensure that no printed circuit board is broken and no component is detached from the
board.
NOTE
The project supervisor should take the major role in the inspection of equipment and components whose
electric characteristics are likely to have been affected.
If... Then...
The packing list indicates "shortage of
articles"
Inform the order management engineer at the
local office. Then, sign the Packing List together
with the customer.
There are any short, wrong, extra, or
damaged items
Representatives of Huawei and the customer
must sign the Unpacking Inspection Memo and
Packing List. The installation supervisor must fill
in the Cargo Problems Report and inform the
order management engineer at the local office in
three days. The installation supervisor must keep
the problematic items intact and the inner and
outer packing intact for future investigation and
verification.
The shipment is intact Place the inspected items by type. Then,
representatives of Huawei and the customer sign
the Packing List.
