Table 29 describes the 20-port 1000BASE-X-SFP module LEDs.

Table 30 lists specifications of the 20-port 1000BASE-X-SFP module.

The 8-port 1000BASE-X GBIC 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
