This topic describes the grounding principle of the MA5608T chassis and the position of the ground point.

Connect the ground cables properly to guarantee protection against lightening and interference for the MA5608T. When a Huawei cabinet is installed, the service subrack is grounded through mounting ears and therefore no separate ground cables are required. When a third-party cabinet is installed, the separate ground cable needs to be connected to the service subrack and ground point on the cabinet.

Ground the chassis shell securely so that the influence electricity, leakage electricity can flow to the ground, improving the protection against electromagnetic interference.

Use a ground cable to connect the ground point of the chassis shell to the ground bar of the telecommunications room or to the ground directly. It is recommended that the grounding resistance of the telecommunications room should be less than 10 ohms. Refer to the local standards to ground the chassis.

The ground point of the chassis shell is on the left of the chassis, and there is a ground point on the front of the left mounting bracket as shown in Figure 2-33.
