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 width of the HUAWEI CLOUDENGINE CE8850-32CQ-EI complies with industry standards and can be installed in a standard 19-inch cabinet/rack complying with IEC297.

• The HUAWEI CLOUDENGINE CE8850-32CQ-EI switch can be installed in a 600 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 switch is 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.

Before You Start

• Determine the directions of the port side and power supply side according to actual situations. If the switch needs to connect to servers in the same cabinet, make port sides of the switch and servers face the same direction to facilitate cable connections. Whether the mounting brackets should be installed near the port side or power supply side depends on the direction in which the chassis is installed. Ensure that 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 guide rails or a tray (self-provided) in the cabinet/rack to support the chassis.

• Switch and mounting bracket mapping table:

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 based on the measured distance.

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.

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 specific models. Installing them in other switch models may damage the fan modules or switches.

Airflow Identification

• 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.

Before You Start

• 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 operation, 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.

Installation Procedure

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.

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. All optical ports on a newly delivered switch are covered with dust plugs.

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

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

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

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

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

C13 straight female to C14 straight male AC power cable:

• Choose this type of power cable when the switch uses AC power modules and receives power from an AC PDU, or when it uses 600 W/1200 W AC&240 V DC power modules and receives power from a 240 V high-voltage DC PDU or power distribution box.

• If a 240 V high-voltage DC power distribution box is used, make OT or cord end terminals for the cable. Cut the C14 straight male connector off and crimp OT or cord end terminals on the bare wires. Connect the brown wire to a negative terminal, the blue wire to a positive terminal, and the yellow-green wire to a protection ground. Notice the positive and negative tags on DC power cables and power terminals.

380 V high-voltage DC power cable:

• Choose this type of power cable when the switch uses high-voltage DC power modules and receives power from a 380 V high-voltage DC power distribution box or frame.

• The delivered cable has bare wires on one end, and OT or cord end terminals must be made for them onsite. Connect the brown wire to the positive pole, blue wire to negative pole, and yellow-green wire to protection ground.

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

USB port:

• The USB port is used to transfer upgrade files and configuration files during a USB-based deployment.

Combo port:

• A GE combo port consists of a GE electrical port and a GE optical port. Only one of them can work at a time.

• Before starting the switch, you can select interface 1 (default) or interface 2 in the BIOS menu.

Before You Start
