Backbone Example Application; Bridging Or Fiber Uplink Example Application - ZyXEL Communications GS1100 Series User Manual

The Switch is Power Sourcing Equipment (PSE) because it provides a source of power via its Ethernet
ports. A powered device (PD) is a device such as an access point or an IP phone, that supports PoE
(Power over Ethernet) so that it can receive power from another device through a 10/100/1000 Mbps
Ethernet port.
In the figure above, the IP camera and IP phone get their power directly from the Switch. Aside from
minimizing the need for cables and wires, PoE removes the hassle of trying to find a nearby electric
outlet to power up devices.

1.3.2 Backbone Example Application

The Switch is an ideal solution for small networks where rapid growth can be expected in the near future.
The Switch can be used standalone for a group of heavy traffic users. You can connect computers and
servers directly to the Switch's port or connect other switches to the Switch.
In this example, all computers can share high-speed applications on the server. To expand the network,
simply add more networking devices such as switches, routers, computers, print servers, and so on.

1.3.3 Bridging or Fiber Uplink Example Application

In this example, the Switch connects different company departments (RD and Sales) to the corporate
backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All
users that need high bandwidth can connect to high-speed department servers via the Switch. You can
provide a super-fast uplink connection by using a Gigabit Ethernet or SFP port on the Switch.
