Mini-GBIC Interfaces
Extreme Networks Consolidated ExtremeXOS Hardware Installation Guide
347
Extreme Networks recommends the following guidelines when installing or replacing mini-GBICs on an
active network:
● Use the same type of mini-GBIC at each end of the link, except for the 1000BX mini-GBIC. The
1000BX mini-GBIC consists of two SFP optical devices, the 1000BASE-BX-U SFP and the
1000BASE-BX-D SFP, which must be used as a pair to allow for a single fiber bidirectional
connection.
● Connect one end of the link to the Tx port. Without an attenuator, measure the total loss from the Tx
port to the other site of the link. The total loss must not exceed the total optical system budget.
Installing and Removing a Mini-GBIC
You can add or remove mini-GBICs from your switch without powering off the system. Figure 238
shows the types of mini-GBIC modules and connectors.
The 1000BX mini-GBIC consists of two SFP optical devices, the 1000BASE-BX-U SFP (Module C) and the
1000BASE-BX-D SFP (Module D), which must be used as a pair to allow for a single fiber bidirectional
connection.See Figure 238.
