Site Environment; Installing The Chassis - Huawei CloudEngine 8800 Series Quick Start Manual

4 Site Environment

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. For
the specific requirements, see the Hardware Description for your switch on the Huawei support website.

5.2 Requirements for the Cabinet
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.
5.3 Installing the Chassis in a Cabinet (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. The figures here are for reference only.
