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