Part 1

6.3 Install the Chassis in the Cabinet/Rack

Tighten the captive screws on mounting brackets.

If MPUs, LPUs, SFUs, power modules, and fan modules have been installed on the switch, you are advised to remove them before installing the switch in the cabinet/rack.

If a power distribution box needs to be installed in the same cabinet/rack as the switch, install the switch ﬁrst, and then the power distribution box.

Do not impose loads on the interior bottom (if any) of the cabinet/rack during the installation.

Protect your personal safety when dragging the metal handles at the rear of chassis.

Installing the Chassis

6.1 Install Floating Nuts and Guide Rails

When marking the positions of ﬂoating nuts and guide rails, keep the bottom edge of the installation

template on the ﬁrst scale tick counted from the bottom.

Positions of mounting brackets only need to be marked on the front mounting rails, whereas positions of

expandable guide rails must be marked on both the front and rear mounting rails. Keep the mounting holes

on the front and rear mounting rails on the same horizontal plane.

(Two persons) Align mounting holes on the installation template with mounting holes on the mounting rails,

and ﬁx the installation template on the mounting rails. Mark positions of the mounting brackets and

expandable guide rails. Then remove the installation template.

Install ﬂoating nuts in the marked mounting holes.

Power Distribution Requirements

If CloudEngine 16800 series switches use AC or high-voltage DC power supply, the PDU installed in the cabinet must provide at least

16 A of rated output current on each line. Replace the PDU if this requirement cannot be met.

If CloudEngine 16800 series switches use DC power supply, the power supply device must provide at least 58.5 A of rated output

current on each line. Replace the power supply device if this requirement cannot be met.

CloudEngine 16800 series switches must be reliably grounded. Circuit breakers with the current leakage protection function are not

recommended for the switches.

Cabinet Requirements

The Huawei A812 cabinet is recommended. To support the chassis in the cabinet/rack, you can use Huawei expandable guide rails

(expandable between 500 mm and 850 mm) or separately purchased guide rails or tray with sufficient load bearing capacity.

A 800 mm wide and 1200 mm deep cabinet/rack is recommended. It is recommended that the distance (distance A in the ﬁgure) between

front mounting tails and the outer side of the front door is in the range from 165 mm to 175 mm, and the distance (distance B in the ﬁgure)

between front and rear mounting rails is in the range from 650 mm to 750 mm.

The cabinet or rack to be adopted must have enough vertical space for device installation:

CloudEngine 16816 DC chassis: ≥ 37U

CloudEngine 16816 AC & high-voltage DC chassis: ≥ 35U

For chassis heat dissipation and convenient maintenance, leave at least 1000 mm of clearance at the front and rear of the switch. Do not

install the switch against a wall.

If the switch is installed in a 600 mm wide cabinet/rack, do not install a PDU directly facing the switch. Otherwise, the installation and

removal of fan modules are affected. When installing a PDU, ensure that the PDU and the switch are installed at different heights in the

cabinet/rack.

The cabinet must have reliable ground terminals for equipment grounding.

Cables must be routed out symmetrically from the left and right sides of the cabinet. An 800 mm wide cabinet can provide sufficient

spacing for cabling.

If you use AC power modules and AC power cables delivered from Huawei, ensure that an AC power source is available within 3 m

(cable distance) away from the power distribution unit (PDU) of the switch. If you use DC power modules, determine the distance from

the power distribution cabinet to the PDU of the switch (cable distance) according to site survey results. DC cables delivered from

Huawei are 20 m long by default.

The cabinet must have sufficient load bearing capacity to support all the devices in it. The minimum load bearing capacity for a single

chassis is 859 kg.

The cabinet must meet the requirements for front-to-back airﬂow, and the front and rear doors must have a porosity rate of more than

55%.

If necessary, use an earthquake-proof cabinet complying with GR63 Zone4 or Zone3 standard.

The following factors must also be taken into account when you select a cabinet:

Site Requirements

The equipment must be installed in a clean, dry, and well ventilated standard

equipment room where temperature can be controlled within a proper range. The

equipment room must be free from leaking or dripping water, heavy dew, and

humidity.

Take dustproof measures in the equipment room. Dust will cause electrostatic

charges on the chassis and affect connections of metal connectors and joints. This

shortens equipment service life and may cause failures of the switch.

The installation site must be free from acidic, alkaline, or other corrosive gases.

The CloudEngine 16816 switch must be used indoors. To ensure normal operations

and long service life of the switch, the installation site must meet the following

requirements:

The temperature and humidity in the installation site must be within allowed

ranges. (See the table below.)

Safety Guidelines

Observe all safety regulations and precautions

Before installing, operating, or maintaining the equipment,

wear an ESD wrist strap and insert the other end into the ESD

jack on the chassis or cabinet. Remove conductive objects like

jewelry and watches to prevent damages to the equipment

and cards caused by electrostatic discharge.

ESD protection

Only trained and qualiﬁed personnel are allowed to install, operate or maintain the

equipment. Familiarize yourself with all safety precautions before performing any

operation on the equipment.

Operator qualiﬁcations

During equipment transport and installation, prevent the equipment from

colliding with objects like doors, walls, or shelves.

Move an unpacked chassis upright. Do not drag it with it lying down.

Do not touch unpainted surfaces of the equipment with wet or contaminated

gloves.

Do not open the ESD bags of cards and modules until they are delivered to the

equipment room. When taking a card out of the ESD bag, do not use the

connector to support the card's weight because this operation will distort the

connector and make the pins on the backplane connector bend.

Do not install or remove the equipment or power cables while power is on.

To ensure equipment and personal safety, ground the equipment before powering

it on.

To ensure personal and equipment safety, observe all the safety precautions on the

equipment and in this document. and

items do not cover all the safety precautions and are only supplementary to the

safety precautions.

Follow all the safety precautions and instructions provided by Huawei. The safety

precautions outlined in this document are only requirements of Huawei and do not

cover general safety regulations. Huawei is not liable for any consequence that

results from violation of regulations pertaining to safe operations or safety codes

pertaining to design, production, and equipment use.

Use multiple persons to move or lift a chassis and take measures to protect

personal safety.

Laser beams will cause eye damage. Do not look into bores of optical modules or

optical ﬁbers without eye protection.
