Network Interface (NI)
Modules
The following section outlines front panel information for
Network Interface (NI) modules, including LED and port
descriptions. For detailed information on all modules, refer to
your
Hardware Users Guide
.
ENI Modules
Ethernet Network Interface (ENI) modules provide Ethernet
connectivity and are available in the following port configura-
tions:
•
OS7-ENI-C24
. Provides 24 twisted-pair ports, auto-
negotiating
and
individually configurable as 10BaseT or
100BaseTX.
•
OS7-ENI-FM12
. Provides 12 100BaseFX (fiber) ports.
•
OS7-ENI-P24
. Provides 24 Ethernet ports for use with
Power over (PoE) configurations. These PoE ports are
twisted-pair and are individually configurable as 10BaseT
or 100BaseTX.
GNI Modules
The Gigabit Ethernet Network Interface (GNI) modules
provide up to twelve 1000 Mbps (1 Gbps) connections per
module. GNI modules can be used for backbone connections
in networks where Gigabit Ethernet is used as the backbone
media. GNI modules can also be used in the wiring closet for
connections to workstations and other devices.
•
OS7-GNI-U2
. Provides two slots for use with hot-
swappable GBICs. Refer to
“Gigabit Interface Converters
(GBICs)” on page 53
for information on connections
supported by GBICs.
•
OS7-GNI-U12
. Provides 12 slots for use with hot-
swappable MiniGBICs. Refer to
“Miniature Gigabit Inter-
face Converters (MiniGBICs)” on page 53
for information
on connections supported by MiniGBICs.
•
OS7-GNI-C12
. Provides 12 auto-sensing copper ports
(10/100/1000BaseT).
