Application Example
The following application example shows one of the many ways OmniSwitch 7700 and 7800 switches can
be used in an Enterprise network setting.
•
Core Switch.
In this example, an OS7800 is used as the core switch. Because the example network has
a high-speed Gigabit Ethernet backbone, the Network Interface (NI) cards in the chassis will be
comprised mainly of Gigabit Ethernet Network Interface (GNI) modules. The core switch connects to
wiring closet switches as well as the company server farm and an OmniPCX, offering effective voice-
data convergence.
•
Wiring Closet Switches.
The switches in wiring closets 1, 2, and 3 must contain some GNI modules in
order to link to the Gigabit Ethernet core switch. However, in most cases, these switches will be largely
comprised of Ethernet Network Interface (ENI) modules. ENI modules support either 10/100 (copper)
or 100BaseFX (fiber) Ethernet connections. These Ethernet ports connect to various network devices,
such as workstations, IP phones, and servers.
