S7700 Smart Routing Switch
Hardware Description
The 24-port 100M/1000M Ethernet optical interface + 8-port 10M/100M/1000M Combo
electrical interface line card (SA, SFP/RJ45) is called G24CA and provides 8 electrical interfaces
and 24 optical interfaces. The first eight optical interfaces are used with the eight electrical
interfaces as combo interfaces.

5.15.2 Function and Application

Function
The G24CA provides 16 GE optical interfaces and 8 combo interfaces. The combo interfaces
can function as either optical interfaces or electrical interfaces.
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.
Application
A G24CA can be installed in any LPU slot of the S7712, S7706, or S7703.
