Ieee 802.3Az Energy Efficient Ethernet; Front Panel Connections; Front Panel Leds - ZyXEL Communications ES1100-16 User Manual

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
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.

2.2.4 Front Panel LEDs

The LED Indicators give real-time information about the status of the Switch. The following tables provide
descriptions of the LEDs.
