Quidway S9300 Terabit Routing Switch
Hardware Description

5.18.1 Introduction

The 24-Port 100/1000BASE-X and 8-Port 10/100/1000BASE-T Combo Interface Card
(EA,SFP/RJ45,1588) is called G24CEAS for short. The G24CEAS provides 8 electrical
interfaces and 24 optical interfaces. Among the 24 optical interfaces, there are eight Combo
interfaces.

5.18.2 Function and Application

Function Description
This board implements 16-channel line-speed switching on GE optical interfaces and 8-channel
line-speed switching on GE combo interfaces. The combo interface can work in optical or
electrical mode. The 100 Mbit/s optical/electrical interfaces and GE optical interfaces of the
G24CEAS support the Ethernet synchronization and 1588 clock synchronization functions.
When the combo interface works as a GE electrical interface, it supports 1588 clock
synchronization, but does not support Ethernet synchronization.
By default, a combo interface works in the auto mode. In the auto mode, if the electrical interface
is connected to a network cable first, the combo interface works as an electrical interface to
transmit data; if the optical interface is connected to a fiber first, the combo interface works as
an optical interface to transmit data.
On the G24CEAS, at most 24 interfaces, including the GE optical interfaces and Combo
interfaces, can work at the same time.
Application
The G24CEAS can be installed in any LPU slot of the S9312, S9306 and S9303.

When using the G24CEAS, install the CKM on the main control board. When the S9300 uses two main
control boards, install CKMs on the two main control boards.
