GNI Modules
Gigabit Ethernet Network Interface (GNI) modules provide up to twelve 1000 Mbps (1 Gbps) connec-
tions per module. GNI modules can be used for backbone connections in networks where Gigabit Ether-
net is used as the backbone media. GNI modules can also be used in the wiring closet.
The following wire-rate 1 Gbps GNI module is available:
•
OS7-GNI-U2.
Provides two GBIC slots. Refer to
for detailed information on this module.
The following high-density Gigabit GNI modules are available:
•
OS7-GNI-U12.
Provides twelve MiniGBIC slots. Refer to
for detailed information on this
module.
•
OS7-GNI2-U12.
Second-generation version of the OS7-GNI-U12. Provides twelve MiniGBIC slots.
Refer to
for detailed information on this module.
•
OS7-GNI-C12.
Provides 12 auto-sensing twisted-pair ports, individually configurable as 10BaseT,
100BaseTX, or 1000BaseT. Refer to
for detailed information on this module.
•
OS7-GNI2-C12.
Second-generation version of the OS7-GNI-C12. Provides 12 auto-sensing twisted-
pair ports, individually configurable as 10BaseT, 100BaseTX, or 1000BaseT. Refer to
for
detailed information on this module.
GBICs and MiniGBICs are Gigabit Ethernet port modules that are hot-pluggable—i.e.,they it can be
installed or removed while the GNI is powered on and operating without the risk of damage to the GBIC/
MiniGBIC module or the host circuitry.
For information on installing GBICs, refer to
. For information on MiniGBICs, refer to
Four GBIC types are available for OS7-GNI-U2 modules:
•
GBIC-SX
—1000BaseSX multimode fiber, supports distances up to 550 meters; uses SC connectors
•
GBIC-LX
—1000BaseLX single mode fiber, supports distances up to 10 km; uses SC connectors
•
GBIC-LH-70
—1000BaseLH long haul fiber, supports distances up to 70 km; uses SC connectors
•
GBIC-C
—1000BaseT copper connection, supports distances up to 100 meters; uses one RJ-45
connector
Three MiniGBIC types are available for OS7-GNI-U12 modules:
•
MINIGBIC-SX
—1000BaseSX multimode fiber, supports distances up to 550 meters; uses LC
connectors
•
MINIGBIC-LX
—1000BaseLX single mode fiber, supports distances up to 10 km; uses LC connec-
tors
•
MINIGBIC-LH-70
—1000BaseLH long haul fiber, supports distances up to 70 km; uses LC connec-
tors
Like ENI modules, GNI modules are also supported during CMM failover. Refer to
for details.
