Checking a Third-Party Cabinet

Checking a Third-Party Cabinet

If a device is to be installed in a cabinet provided by a third party, you must check the cabinet to ensure that it meets device installation conditions.

Before hardware installation, a third-party cabinet provided by a user must be checked by both the user and a Huawei hardware installation engineer to ensure that it meets device installation and operation requirements. Table 7-1 lists the check items.
Table 7-1  Check items for a third-party cabinet


Check Item



Ground bearing of the equipment room

Not smaller than 600 kg per square meter

□Yes □No


Cabinet parameters

The mechanical structure and size comply with IEC 60297 482.6 mm (19") standards.

□Yes □No

The size meets standards as shown in Figure 7-1.

Depth ≥ 1000 mm

□Yes □No


Available installation space (U)


Indicates the space that is available for installing a Huawei device. Each P36/C36/C72/P36E/C36E requires a 4 U space and each P25/P12/P25E/P12E requires a 2 U space.

Cabinet bearing capacity ≥ 600 kg

□Yes □No

It can hold devices that are loaded.

Guide rail (tray) bearing capacity ≥ 50 kg

□Yes □No


Shape of holes on a mounting bar

□ Square hole (side length ≥ 9.5 mm x 9.5 mm)

□ Round hole (diameter ≥ Ф 7 mm)


Distance between the front mounting bar and the front door ≥ 100 mm

□Yes □No


600 mm ≤ distance between the front and rear mounting bars ≤ 900 mm

□Yes □No

If a cabinet has guide rails or trays, skip this item.

Distance between the front mounting bar and rear door ≥ 700 mm

□Yes □No


Porosity for front and rear doors > 50%

□Yes □No


Door open angle ≥ 120º

□Yes □No

A small door open angle hinders loading, unloading, and maintaining devices.

Device support parts (guide rail, tray) occupy cabinet space.

□Yes □No

If Yes is selected, count the space occupied by support parts into the internal available space of a cabinet. For example, available space for each P25/P12/P25E/P12E increases to 3 U and 5 U for P36/C36/C72/P36E/C36E.

No part protrudes into device installation area to affect device installation.

□Yes □No

Protruding parts include cabinet mechanical parts, power cable plugs, and PDUs.

Cabinet power system

The cabinet supports dual power inputs.

□Yes □No


AC power nominal voltage (V)

□ 220 V AC

□ 110 V AC

The storage node supports both 110 V AC and 220 V AC.

Current of each channel of AC power (A)


Refers to single device power consumption and device quantity.

The number of power sockets available for each channel of each cabinet (pcs)


Each storage node and each LAN switch require 1+1 power supply. KVM requires one power supply.

Power socket type

□ IEC standards

□ PRC standards

□ USA standards

□ UK/Singapore/Hong Kong standards

□ Australia standards

□ France standards

□ Germany standards

□ Others_______

Generally, each storage node is equipped with two standard power cables and two PDU power cables. The cabinet must be equipped with a standard three-pin socket or C13 port. If the onsite situation fails to meet this condition, figure out other solutions to resolve the problem.

Ground point

□Yes □No

M6 screws are required for the ground points in a 19" standard cabinet.
