• 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 where you install your HUAWEI CLOUDENGINE CE6851-48S6Q-HI 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 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.

This procedure applies to CE8850-32CQ-EI and CE7800&6800&5800 series switches.

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.

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. Refer to the mounting bracket and guide rail bundle tables for your specific model and cabinet depth.

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 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.

Before You Start:

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

Installation Procedure:

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 these models are at the power supply side of the switches.

Selecting Modules:

• 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 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 are identified by an “AIR OUT” flag. Air flows from the port side to the power supply side.

Installing Modules:

• If the switch is delivered with the 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 operation, the switch must have two normally running fan modules.

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

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.

• 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.

A fan module is installed the same way as a power module fixed with captive screws.

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

Before You Start:

• 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.
