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.

The installation site for the HUAWEI CLOUDENGINE CE6881 must meet the following requirements:

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 cabinet for installing a HUAWEI CLOUDENGINE CE6881 must meet the following 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, whereas the CE6800 (600 mm deep), CE7800, CE8850-64CQ-EI, CE8860, CE8861 and CE8868 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 CE8800&7800&6800&5800 series 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.

Before installing the HUAWEI CLOUDENGINE CE6881 chassis, you should:

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.

Follow these steps to install the chassis:

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 the appropriate mounting brackets to the switch with M4 screws, based on the measured distance. For example:

For CE8850-32CQ-EI & 6800 & 5800 (420 mm deep):

310 mm-351 mm: Mounting bracket A + Mounting bracket B + Guide rail E

369 mm-410 mm: Mounting bracket A + Mounting bracket B + Guide rail E

438 mm-479 mm: Mounting bracket A + Mounting bracket B + Guide rail E

497 mm-538 mm: Mounting bracket A + Mounting bracket B + Guide rail E

539 mm-637 mm: Mounting bracket A + Mounting bracket C + Guide rail E

638 mm-696 mm: Mounting bracket A + Mounting bracket C + Guide rail F

697 mm-835 mm: Mounting bracket A + Mounting bracket C + Guide rail F

For CE7800 & 6800 (600 mm deep):

493 mm-548 mm: Mounting bracket A + Mounting bracket C + Guide rail E (Note: If the cabinet is 800 mm deep, mounting bracket C will touch the cabinet door.)

549 mm-551 mm: Mounting bracket A + Mounting bracket C + Guide rail E (Note: Install mounting bracket C in mounting holes at middle of the chassis.)

552 mm-680 mm: Mounting bracket A + Mounting bracket C + Guide rail E (Note: If the cabinet is 800 mm deep, mounting bracket C will touch the cabinet door.)

681 mm-815 mm: Mounting bracket A + Mounting bracket C + Guide rail E

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 the CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI and CE6875EI is 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.

These models require 3U of vertical space in a cabinet/rack.

Step 1: Mount the expandable guide rails on the mounting rails.

a. Hold a guide rail with its front side facing the front of the cabinet and move it to the planned position. Expand the guide rail and hook both sides on the mounting rails. Ensure that the three holes on the guide rails are in the same 1U space.

b. Insert plugs on the top holes on both sides of the guide rail to secure the guide rail.

c. Install an M6 screw in the lowest hole on the rear side of the guide rail.

d. (Optional) Install an M6 screw in the lowest hole on the front side of the guide rail to enhance shock resistance of the switch.

Step 2: Install two floating nuts in the 1U space above the guide rail on each front mounting rail.

Step 3: Install the front mounting brackets near the power supply side or port side depending on which side is facing the front.

Step 4: Install the switch in the cabinet.

a. Lift the switch onto the expandable guide rails by two persons.

b. Slowly push the switch into the cabinet until the front mounting brackets are closely attached to the floating nuts on the mounting rails.

c. Secure the front mounting brackets on the mounting rails with M6 screws.

Step 5: Connect the ground cable to a ground point on the cabinet. The ground points of the CE8860, CE8861, CE8868 and CE8850-64CQ-EI are at the power supply side of the switches.

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.

Airflow Direction:

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 Installation:

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

Before installing a 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 and fan modules are hot pluggable. A fan module is installed the same way as a power module fixed with captive screws. There are two types of installation:

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.

Before You Start:

Only the CE8860, CE8861 and CE8868 switches have extended slots for card installation.

Install a filler panel in a vacant slot.

Slowly push a card into the slot. If you feel resistance or find the card inclined, pull the card out and push it into the slot again. Forcing the card into the slot may damage connectors on the card and backplane.

All cards are hot swappable.

Installation Procedure:

Step 1: Press the two green locking clips in the middle of the filler panel to eject the ejector levers.

Step 2: Turn the ejector levers outward and slowly pull the filler panel out.

Step 3: Press the two green locking clips in the middle of the card to eject the ejector levers.

Step 4: Slowly push the card into the slot, and then turn the ejector levers inward to lock the card in the slot. When the card is completely seated in the slot, the ejector levers will buckle with the locking clips.

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.

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. Connect the brown wire to a negative terminal, the blue wire to a positive terminal, and the yellow-green wire to a protection ground.

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.

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.

Mini USB Port:

Specific models (CE8860, CE8861, CE8868, CE8850-64CQ-EI, CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI and CE6875EI) have a Mini USB port, which provides the same functions as a console port.

The Mini USB port and console port cannot be used together. When both ports are connected, only the Mini USB port is active.

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

Combo Port:

Specific models have two ETH management ports, each of which is a GE combo port. Other models have two ETH management ports (GE RJ45).

The two ETH management ports cannot be used simultaneously. Choose one and use the other as a backup.

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