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.

Indicator status when the switch is working properly

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. 

When the                                                                  indicators on the chassis header are in normal state (steady green), check the 

indicators on other modules.

Connecting Cables

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

1

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.

7.3 Install Power Modules

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.

2

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.
