Huawei EA5801-CG04 EA5801-CG08 box-shaped OLT Service Subrack

Huawei EA5801-CG04 box-shaped OLT Service Subrack

The EA5800-X2 service subrack is 2 U high, and has a fan tray at the right. The subrack is installed in the cabinet through the mounting brackets.

 ESD Jack

The ESD jack of the EA5800-X2 service subrack is on the bottom of the fan tray, which is used to connect the ESD wrist strap to prevent device damage caused by electrostatic discharge.

Grounding

 NOTICE:

Connect the ground cables properly to guarantee protection against lightening and interference for the EA5800-X2 subrack. 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.

The EA5800-X2 subrack has 2 ground points. One is on the side panel and the other is at the middle of the right mounting bracket of the subrack,

The power input end of the EA5800-X2 has a noise filter. The center ground of the noise filter connects to the subrack, called the chassis shell ground, that is, the protection ground. Ground the subrack 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 subrack 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 subrack.

We hope that we can establish a good and long time business relationship with you.
