SL91EG4P,EG4P,Huawei OptiX RTN 900 Series IDU Boards

Huawei RTN 900 Board SL91EG4P Overview

The EG4/EG4P is a 4xGE interface board. Different types of interfaces can be flexibly combined based on service requirements. Among ports on the EG4/EG4P, two ports are always RJ45 electrical ports and the other two ports can be SFP ports or RJ45 electrical ports. Among ports on the EG4P, two ports are always RJ45 electrical ports to supply power over Ethernet.

The functional version of the EG4/EG4P is SL91.

The EG4/EG4P receives and transmits GE services or carry MPLS tunnels.

The EG4/EG4P receives/transmits, processes, and converges four channels of GE service signals. The EG4/EG4P can also receive/transmit two channels of FE optical signals using FE SFP optical modules installed at the SFP ports.

There are indicators and GE service ports on the front panel of the EG4/EG4P. Additionally, the EG4P has a power caution label.

The EG4/EG4P can be inserted in Slots 1 to 14, which have consistent logical slot numbers on the NMS.

The FE/GE SFP ports on the EG4/EG4P support multiple types of SFP modules.

Functions and Features

Function and Feature		Description
