Checking the Cabinet/Rack

Checking the Cabinet/Rack

Table 4-2 describes the requirements for the cabinet/rack where the CloudEngine 8800, 7800, 6800, and 5800 series switches can be installed.

Table 4-2 Requirements for the cabinet/rack




Use a standard 19-inch four-post cabinet or rack. The CE8850-32CQ-EI, CE7800, CE6800, and CE5800 series switches are 43.6 mm high, and the CE8850-64CQ-EI, CE8860, CE8861, and CE8868 are 88.1 mm high. With their widths in compliance with industry standards, these switches can be installed in a standard 19 inch cabinet/rack.


A separately purchased non-standard cabinet/rack must have sufficient space for chassis installation. The cabinet for a CE5800, CE6800 (420 mm deep), or CE8850-32CQ-EI switch must be no less than 600 mm deep, and the cabinet for a CE6800 (600 mm deep), CE7800, CE8850-64CQ-EI, CE8860, CE8861, or CE8868 switch must be no less than 800 mm deep.

Heat dissipation

The CloudEngine 8800, 7800, 6800, and 5800 series switches use front-to-back or back-to-front airflow design. The cabinet must meet the requirement of the airflow.


The cabinet must have reliable ground points to ground the chassis.

Distance between front and rear mounting rails

When the CloudEngine 8800, 7800, 6800, and 5800 series switches need to be installed in the same cabinet with a CloudEngine 12800 switch, keep the distance between the front and rear mounting rails in the range of 700 mm to 800 mm.

Cabling space

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 vertical 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.

Figure 4-1 shows the points from which to take measurements for the cabinet width (a), the cabinet depth (b), and the distance between front and rear mounting rails (c).
