Installing Modules
7.1 Slot Description
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
mounting hole 5
device. Otherwise, the device may be damaged.

7.2 Install Cable Management Frames
1
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.
7.3 Install Power Modules
2
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.
7.4 Install 1U Filler Panels

7.5 Install SFUs
1
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
CloudEngine 16816
attached to the interior sides of the slot. Close the wrenches until the SFU is in full and secure contact with the chassis.
mounting hole 7
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
2
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.

Powering On the Chassis
Before performing a power-on check, ensure that power switches on
the external power supply system and the switch are turned off.
Verify that the input voltage is within the operating voltage range for the switch.
Turn on the power switches on the external power supply system and then the two power switches on the chassis to power it on. The
chassis can be powered on when one power switch is turned on. However, to ensure reliable system power supply, both power switches
must be in ON state when the chassis is running.

7.9 Install Chassis Doors
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.
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
2
and lower enclosure frames horizontally, and tighten the captive screws on the upper and lower enclosure frames.
3
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.
NOTE
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.

Connecting Cables
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.
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
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.
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.

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.
