What Requirements Should Cabinets for the CE Series Switches Meet?

What Requirements Should Cabinets for the CE Series Switches Meet?

CloudEngine 12800 and 12800E

A standard 19-inch four-post cabinet or rack is recommended for the CloudEngine 12800 and 12800E series switches. Use Huawei expandable guide rails to support the chassis in the cabinet/rack. Expandable guide rails for the CE12804/CE12808/CE12812/CE12816 switches are expandable between 700 mm to 900 mm, and expandable guide rails for the CE12804S/CE12808S/CE12804E/CE12808E/CE12816E switches are expandable between 500 mm and 850 mm. If you use third-party guide rails or trays, ensure that they have sufficient load bearing capacity.

A Huawei CE12800 and CE12800E cabinet can accommodate two CE12808 switches. To install two CE12808 switches in the same cabinet, install a switch at the bottom and then install the other on the top. Leave certain space above and below the two switches for cabling.

The power distribution unit (PDU) in the cabinet provides both 10 A PDU (C13) and 16 A PDU (C19) sockets. If you want to connect a CloudEngine 12800 or a CloudEngine 12800E switch and another small-sized device to the PDU simultaneously, properly plan the power cable connections to ensure reliable power supply for the two devices. (Sockets on the PDU are divided into different groups for proper power cable connections.) Ensure that the fault of one device does not affect the other device.

A cabinet for the CloudEngine 12800 and 12800E series switches must meet the following requirements:

  • The cabinet/rack must provide reliable ground points for switch grounding. (The ground cable delivered with a switch is 850 mm long.)
  • The cabinet/rack must meet the requirements for front-to-back airflow. The cabinet must meet the requirements for front-to-back airflow, and the front and rear doors must have a porosity rate of more than 50%.
  • If you use AC power cables delivered from Huawei, ensure that an AC power outlet is available within 3000 mm (cable distance) away from the switch.
  • The cabinet must be installed on concrete floor or ESD floor (placed on the floor directly or fixed by expansion bolts). If necessary, use an earthquake-proof cabinet complying with GR63 Zone4 or Zone3 standard.

In addition to the preceding requirements, different models of the CloudEngine series have their own requirements for a cabinet/rack, as described in Table 22-4.

CloudEngine 8800, 7800, 6800, and 5800

Table 22-5 describes the requirements of CloudEngine 8800, 7800, 6800, and 5800 series switches for a cabinet/rack.

Table 22-5 Requirements for the cabinet/rack

Item

Requirement

Width

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.

Depth

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.

Grounding

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.
