1.1.1 Power over Ethernet (PoE)
The Switch is a Power Sourcing Equipment (PSE) because it provides a source of power via its Ethernet
ports. Each device that receives power through an Ethernet port is a Powered Device (PD).
The Switch is configured in consumption mode, that is, it supplies the actual power the PD needs.
The Switch supports the IEEE 802.3af Power over Ethernet (PoE) standard.
The Switch supplies power with the lowest numbered port having the highest priority by default. For
example, port 1 has the highest priority, port 2 the next, and so on.
Not all models support PoE. See Table 1 on page 5.
Key PoE feature comparison is as follows:
1.2 Applications
This section provides two network topology examples in which the Switch is used.
1.2.1 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 etc.

An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover
Ethernet cable.
2.2.2 IEEE 802.3az Energy Efficient Ethernet
The Switch supports the IEEE 802.3az EEE (Energy Efficient Ethernet) standard to help reduce power
consumption. This allows the Switch to go into power saving mode and switch off part of receive and
transmit circuitry when it is not transmitting or receiving data through an Ethernet connection. See
Section 1.1 on page 5 to check which devices support EEE.
An EEE-enabled device initiates Low Power Idle (LPI) signals to negotiate and wake up the remote
device when there is data to be transmitted. To use EEE, both devices should be EEE compliant.
EEE is configured on a per-system basis in the Switch. If one of the networking devices that connect to
the Switch doesn't support EEE, EEE may not work in the Switch to save power.
The EEE feature is enabled by default on the ES1100-16, ES1100-24 and ES1100-24E. Press in the IEEE
802.3az EEE ON/OFF button on the ES1100-8P and ES1100-16P front panel to turn on the EEE feature.
Disable it if the remote side doesn't support it or you don't want the network performance to be
impacted due to the latency from the additional time required for the sleep and wake transition.
2.2.3 Front Panel Connections
You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet cables for RJ-45 ports.
The following table describes the types of network cable used for the different connection speeds.
You can use either crossover or straight-through cables for all the ports.
