1 Ethernet port
2 Ethernet port LED
Each 100 Mbps Ethernet port has a green LED, indicating LINK/ACTIVE status.
Table 15 describes the 48-port 10/100BASE-T Auto-sensing FE module LED.
Table 16 describes the specifications of the 48-port 10/100BASE-T Auto-sensing FE
module.
See “Electrical Port Connector” on page 64 for an illustration of the RJ-45
connector and MDI/MDI-X pinout details.
8-port 1000BASE-X GE
Module
The 8-port 1000BASE-X GE module provides 8 external GBIC module ports. A
GBIC module is used for each data receiving/transmitting channel. The following
modules are available:
■ 3CGBIC91
■ 3CGBIC92
■ 3CGBIC97
Figure 7 illustrates the 8-port 1000BASE-X GE module.
