Note: The numbers and types of items in the installation accessory package differ for different product models.

To ensure personal and equipment safety, observe all the safety precautions on the equipment and in this document. Follow all the safety precautions and instructions provided by Huawei.

WARNING:

• Laser beams will cause eye damage. Do not look into bores of optical modules or optical fibers without eye protection.

• Do not install power cables while the power is on.

• Do not turn on the power until you have finished installing the chassis and connecting cables.

CAUTION:

• This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.

• Take ESD protection measures during equipment installation and maintenance. For example, wear ESD gloves or an ESD wrist strap.

• Do not place other objects on the chassis.

• Do not place this product in an environment with flammable or explosive gases, or smoke.

• The installation site must be free from leaking or dripping water, heavy dew, and humidity. If the relative humidity is high, use dehumidifiers or dehumidifying air conditioners.

• The installation site must be well ventilated. Ensure that air vents on the equipment are not blocked.

• Leave at least 50 mm clearance at the rear and both sides of the chassis for heat dissipation.

• Ensure that the temperature and humidity at the installation site meet the switch operation requirements.

• The widths of CE8800, CE7800, CE6800, and CE5800 series switches comply with industry standards. Therefore, these switches can be installed in a standard 19-inch cabinet/rack complying with IEC297.

• The CE5800, CE6800 (420 mm deep) and CE8850-32CQ-EI switches can be installed in a 600 mm or deeper cabinet. The CE6800 (600 mm deep), CE7800, and other larger models can be installed in an 800 mm or deeper cabinet.

• On a switch, the side with power modules and fan modules is the power supply side, and the side with service ports is the port side. To leave sufficient cabling space, ensure that the distances from the port side and power supply side to the interior side of the cabinet doors are at least 130 mm and 70 mm respectively.

• The cabinet must have a reliable ground point to ground the switch.

• If the switches are installed in the same cabinet with a CE12800 switch, keep a distance of 700 mm to 800 mm between the front and rear mounting rails.

The HUAWEI CLOUDENGINE CE6857-48S6CQ-EI is a CE6800 series switch (420 mm deep). The following table shows the supported mounting hardware:

Before you start, determine the directions of the port side and power supply side according to your setup. Ensure the rear mounting brackets will not touch the cabinet door. If the distance between front and rear mounting rails is not within the required range, install self-provided guide rails or a tray to support the chassis.

Installation Procedure:

Step 1. Measure the distance between the front and rear mounting rails. The type and installation method of mounting brackets and matching guide rails vary depending on this distance.

Step 2. Fix mounting brackets to the switch with M4 screws. The specific combination of brackets and guide rails depends on the measured distance from Step 1.

Step 3. Install eight floating nuts on the front and rear mounting rails, two on each mounting rail.

Step 4. Connect the ground cable to the chassis ground point and place the other end on top of the chassis. The ground point of some models may be located at the power supply side.

Step 5. Secure guide rails on the front mounting rails with M6 screws.

Step 6. Hold the bottom of the chassis with both hands, align the mounting brackets with the guide rails, and slowly slide the chassis into the cabinet.

Step 7. Secure the chassis onto the cabinet with M6 screws.

Step 8. Connect the ground cable to the ground point on the cabinet.

CAUTION:

• The switch must use the power modules and fan modules matching the product model.

• The power modules and fan modules used in the switch must have the same airflow direction.

• Power modules with different airflow directions or power values, AC and DC power modules, or fan modules with different airflow directions cannot be used in the same chassis.

• FAN-060A series fan modules can only be installed in CE6850HI, CE6850U-HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI and CE6875EI. Installing them in other switch models may damage the fan modules or switches.

• Front-to-back airflow: Power modules and fan modules with front-to-back airflow are identified by an “AIR IN” flag. Air flows from the power supply side to the port side.

• Back-to-front airflow: Power modules and fan modules with back-to-front airflow are identified by an “AIR OUT” flag. Air flows from the port side to the power supply side.

• If the switch is delivered with the power modules and fan modules installed in the chassis, you do not need to install them again.

• Before installing a power module or fan module, remove the filler panel in the slot.

• If only one power module is used, install a filler panel in the other power module slot.

• To ensure normal operating, the switch must have two normally running fan modules.

• Do not remove the two fan modules from the chassis simultaneously. Replace a fan module within 3 minutes.

Power modules fixed using a captive screw and a lock are installed differently. Power modules and fan modules are hot pluggable. A fan module is installed the same way as a power module fixed with captive screws.

For a power module secured by a captive screw:

Step 1. Insert the power module into a power slot.

Step 2. Tighten the captive screw on the power module panel.

For a power module secured by a lock:

Insert the power module into a power slot. When the power module is completely seated in the slot, the lock is locked automatically.

Ground cable:

• The switch must be reliably grounded.

• Attach the M4 lug to the switch and the M6 lug to the ground point.

Ethernet cable:

• Category 5E or higher category Ethernet cables are recommended for GE electrical ports.

• Category 6A shielded or higher category Ethernet cables are recommended for 10GE electrical ports.

• To protect the switch from lightning, route outdoor cables underground or in steel pipes. Do not route cables aerially.

Optical fiber:

• Optical fibers must be used with optical modules. Connectors of fibers and cables must be clean.

• Cover idle optical ports with dust plugs.

• The bend radius of optical fibers must be larger than 40 mm.

• 10GE optical ports use SFP/SFP+ optical modules and fibers, SFP+ AOC, or SFP+ copper cables.

• 25GE optical ports use SFP/SFP+ or SFP28 optical modules and fibers, SFP+ or SFP28 AOC, or SFP+ or SFP28 copper cables.

• 40GE optical ports use QSFP+ optical modules and fibers, QSFP+ AOC, or QSFP+ copper cables.

• 100GE optical ports use QSFP+/QSFP28 optical modules and fibers, QSFP+/QSFP28 AOC, or QSFP+/QSFP28 copper cables.

Country-specific AC power cable:

• Power cables must be more than 10 cm away from signal cables.

• The country-specific AC power outlet must have a current rating of 10 A and comply with local standards.

• The AC power cable must be locked using a locking strap or bundled to the power module handle using a velcro strap.

The following table describes the typical cable connections for a HUAWEI CloudEngine switch:

Before you start, install third-party terminal simulation software on your PC.

Login Procedure:

Step 1. Use a console cable to connect a PC to the console port of the switch.

Step 2. Start the terminal simulation software, create a connection, select a serial port, and set the following communication parameters:

• Transmission rate: 9600

• Data bit (B): 8

• Parity bit: None

• Stop bit (S): 1

• Flow control mode: None

Step 3. Press Enter, and then enter a password as prompted. The configured password will be saved in the system.

When prompted `Continue to set it? [Y/N]:`, enter `y` and set a password.

Notes:

• By default, the system will start the zero-touch provisioning (ZTP) process. To cancel this process, press Ctrl+C.

• The password entered in interactive mode is not displayed on the screen.

• If password authentication is not configured, you do not need to enter a password, but this brings security risks. Password authentication is recommended.

• The password is a string of 8 to 16 case-sensitive characters. It must contain at least two types of the following: uppercase letters, lowercase letters, digits 0 to 9, and special characters excluding question mark (?) and spaces.

• After a login password is configured, this password will be required upon next login if password authentication is used on this user interface.

• If you forget the login password, see the Troubleshooting section to restore the password.
