Connecting Cables
8
Route cables
Route cables out of the chassis from the left and right sides symmetrically.
Pull the plastic parts of the cable management frames out a little, route
cables through the cable management frames, and then push the plastic
parts in place.
Bundle power cables at 250-mm intervals and use cable ties to fix them
on the rack.
Power cables and ground cables must be more than 30 mm away from
signal cables.
Use cable ties to bundle Ethernet cables and high-speed cables to the rack
at 250-mm intervals. Use binding straps to bundle optical fibers and AOC
cables at 250-mm intervals and use cable ties to fix them on the rack.
Arrange the fibers neatly and route them along the cable tray.
Connect power cables
Before connecting power cables, ensure that both power switches on the chassis are turned off.
To ensure that the connectors and maximum current of power cables meet requirements of the switch, use the power cables delivered with the switch.
The power sockets on the power distribution unit at the rear of chassis and the power modules at the front of chassis have a one-to-one mapping.
Follow the power redundancy principle when connecting power cables. Do not insert all the power cables to the sockets connected to the same circuit breaker on
the PDU.
Do not bend OT terminals to 90 degrees onsite.
For details about cables and optical modules, see the
.
The ground point of CloudEngine 16800 series switches is located at the rear of the chassis and supports a ground cable with a two-hole OT terminal.
If only one power source is available in the equipment room, connect all PMs to power source A (terminal blocks or power sockets A1 to A20) or power source B
(terminal blocks or power sockets B1 to B20).
When both power sources A and B are available:
In AC or high-voltage DC scenarios, power source A is used by default. If power source A is faulty, the system automatically switches to power source B.
In DC scenarios, if the two power sources have different voltages, the power source with a higher voltage provides a higher current.
Requirements for the power distribution of a customer's cabinet: The output power of power sources A and B must be greater than the maximum input power of
the switch
When routing power cables, Ethernet cables, and high-speed cables, route low-voltage cables separately from high-voltage cables. Metallic strength members and
metal armor used in optical fibers must not be routed into the cabinet/rack.
Connect the ground cable before connecting other cables.
When using a ground cable with a one-hole OT terminal, route the ground cable properly to prevent it from hindering installation and removal of fan modules.
Connect signal cables
Cover idle optical ports and optical modules with dust plugs and cover idle
optical fibers with dust caps.
A fiber's bend radius must be 20 times larger than the fiber's diameter, and is
generally greater than or equal to 40 mm.
Overbending of high-speed cables may damage wires in the cables. The bend
radius of high-speed cables must be larger than their minimum bend radius.
The bend radius of AOC cables must be no less than 30 mm.
Do not bundle fibers too tightly. Ensure that you can easily remove a single
fiber from the bundle.
Use an Ethernet cable tester to test conductivity of Ethernet cables before
bundling them.
7.2 Install Cable Management Frames

7.4 Install 1U Filler Panels
Insert the positioning pins of a cable management frame into mounting holes on the chassis, slide the cable management frame up and down to fit the
positioning pins in the recess of the mounting holes, and tighten the captive screws on the cable management frame. Tighten the captive screws with a torque
of 0.54 N·m.
7.7 Install Fan Modules
SFU slots SFU1, SFU2, and SFU9 cannot be used.
Vacant slots must be inserted with fifiller panels.
Before installing a card, power module, or fan module, remove filler panels at the rear of the switch and from the corresponding slot. Keep the removed filler
panels in an appropriate place for future use.

Do not remove filler panels from vacant slots to ensure good electromagnetic shielding, heat dissipation, and dustproof performance.
Before the installation, ensure that the chassis and modules are free from water drips.
When installing a card, ensure that ejector levers of the card are at the bottom to avoid incorrect card installation. Incorrect card installation will damage the
connector at the rear of the card.
When installing a card, gently push the card along the guide rails, and be careful not to crash the card connector. Distorted card connector will cause pins on the
opposite card connector or backplane connector to bend.
If the connector of a card has collided with the slot or other object, ask Huawei professionals whether the card can still be installed. Installing a card with distorted
connector will cause damages to the switch.
Do not install an MPU in an LPU slot or install an LPU in an MPU slot.
Install two MPUs of the same type into the active and standby MPU slots on a device. Only P series and SAN series of LPUs or SFUs can be installed on the same
device. Otherwise, the device may be damaged.

Power Distribution Requirements
5
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
4
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
3
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.)

The first half of the mounting bracket does not need to be adjusted. Therefore, do not uninstall any screw
used to fix the first half.
Gently push a power module into the slot along the guide rails until you hear a click and the power module cannot move forward.
Do not install both DC and AC power modules on the same switch.
When installing a power module, ensure that the indicator on the power module is on the top.

Install 1U filler panels in the cabinet/rack. Place the bottom of a filler panel against the top of the chassis.
7.5 Install SFUs
Do not carry an SFU horizontally
by one person because it is
heavy and long. Two persons are
required when moving an SFU
for a long distance. To prevent
personal injury or damage to the
SFU, follow the preceding steps.
Perform the following steps to install an SFU:
a. Remove filler panels at the rear of the switch and from the slot where an SFU will be installed. Hold the top of the SFU
with both hands and stand the SFU upright. Take the SFU out from the ESD bag.
b. Open the handle on the left side of the SFU. Grasp the handle with one hand and the top of the SFU with the other
hand to stabilize the SFU. Another person removes the latches on the SFU.
c. Place the SFU in the slot and gently push the SFU along the guide rails.
d. Take out the wrenches delivered with the SFU and install the wrenches onto the SFU. If you hear a click, the wrenches
have been installed. Grasp the wrenches with both hands, and gently push the SFU until the hooks of the wrenches are
attached to the interior sides of the slot. Close the wrenches until the SFU is in full and secure contact with the chassis.
e. Remove the wrenches. Press and hold down a round button on the SFU with one hand, hold a wrench with the other
hand, and remove the wrench downwards.
7.6 Install Wrench Storage Box of the SFU
First tilt the wrench storage box of the SFU down to the bottom of the chassis, flatten it and attach it to the bottom of the chassis.
Finally tighten the M3 screws for 3 holes, tighten the captive screws with a torque of 0.54 N·m.
Perform the following steps to install a fan module:
a. Press the release buttons on the right side of the two fan module handles.
b. Turn the fan module handles out.
c. Hold the handles with both hands and gently push the fan module into the slot along the guide rails.
d. Press the release buttons on the right side of the fan module handles to fold the handles.
e. Tighten the captive screws on the fan module. Tighten the captive screws with a torque of 0.54 N·m.
Do not stand a fan module upright to avoid
it falling over and causing damage or injury.
To prevent a fan module from falling down,
hold both handles while removing it.

7.8 Install MPUs and LPUs
7.9 Install Chassis Doors
Components of the chassis door include dedicated cable
management frames. When installing the chassis door
components, you do not need to install the cable management
frames that are delivered with the chassis.
Figures show chassis door installation on the CloudEngine 16808.
1
Install cable management frames on the device. Insert the positioning pins of a cable management frame into mounting holes on the device, insert the
cable management frame horizontally, and tighten the captive screws on the cable management frame.
2
Install upper and lower enclosure frames on the device. Align the upper and lower enclosure frames with mounting holes on the device, insert the upper
and lower enclosure frames horizontally, and tighten the captive screws on the upper and lower enclosure frames.
Install a chassis door on the device.
a. Align the buckles at the bottom of the chassis door with the lower
enclosure frame and insert the buckles.
b. Push the chassis door to the upper enclosure frame until you hear a click
indicating that hooks of the chassis door clasp in the upper enclosure frame.
