LED ecoFriendly Push Button
The LED ecoFriendly push button is located next to the Power LED on the
left-hand side of the front panel as illustrated in Figure 3. It enables the
LED Low Power Mode (LPM) feature. This mode allows you to conserve
power by turning off the port status LEDs when you do not required the
LED status indications on the front panel. To toggle the LEDs on or off,
press the ecoFriendly button. The LPM feature does not affect the the
Power LED or the network operations of the switch ports.

Twisted-Pair
Ports
Type of Connector
The twisted-pair ports feature 8-pin RJ-45 connectors. (For the port
pinouts, refer to “RJ-45 Twisted-Pair Port Connectors” on page 40.
Speed
The ports are 10Base-T and 100Base-T compliant and are capable of
10 megabits per second (Mbps) and 100 Mbps speeds. The ports are
IEEE 802.3u Auto-Negotiation compliant. With Auto-Negotiation, the
switch automatically matches the highest possible common speed
between each switch port and each end-node. For example, if an end-
node is capable of only 10 Mbps, the switch sets the port connected to the
end-node to 10 Mbps.
Duplex Mode
Each twisted-pair port on these switches can operate in either half- or full
duplex mode. The twisted-pair ports are IEEE 802.3u-compliant and will
Auto-Negotiate the duplex mode setting.
Note
In order for the switch to set the duplex mode for each port correctly,
the end-nodes that you connect to the switch ports should also use
Auto-Negotiation. Otherwise, a duplex mode mismatch can occur,
affecting network performance. For further information, refer to
“Duplex Mode” on page 18.
