OmniSwitch Troubleshooting Guide

The Firenze basically provides three functions: Media Access Control (MAC) Layer functions, Data buff-
ering, Flow Control and statistics accumulation and storage for each port. 

Firenze handles up to six Ethernet interfaces that can support independently either 10 or 100 or 1000 Mbit/
s throughput using independently either TBI or GMII interfaces.

The Firenze Based GNI is a 1Gbps Ethernet Switching Module for the Falcon system. Two Versions of 
the board are configured as below:

• GNI-U12, 12-port fiber Gigabit module equipped with twelve Pluggable SFP Transceivers which can 

support short, long and very long haul applications.

• GNI-C12, 12-port copper Gigabit module equipped with twelve RJ45 connector, individually config-

urable as 10/100 or 1000 Base-T.

The Firenze based GNI modules for Eagle OS-8800 are as follows:

• OS8-GNI2-C24, 24-port copper Gigabit module equipped with Twenty four RJ45 connector compati-

ble with cat5 or cat5e minimum cabling specification. Due to the use of Ten-Bit Interface

• TBI between the PHY and Firenze, the ports are limited to 1000BASE-T speed only.

• GNI2-U24, 24-port fiber Gigabit module equipped with Twenty four Pluggable SFP Transceivers.
