LED Indicators
The front panel of the Ethernet Switch contains several LED indicators.
The function of each LED is described in the table below.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows connecting devices to an Ethernet
Switch’s 10/100BaseT(X) port without paying attention to the type of
Ethernet cable being used for the connection. This means that you can
use either a straight-through cable or cross-over cable to connect
devices to the Ethernet Switch.
Auto-Negotiation and Speed Sensing
Each RJ45 Ethernet port independently supports auto-negotiation for
recognizing the transmission speed 10 Mbps or 100 Mbps according to
the IEEE802.3 standard. This means that some of connected Ethernet
devices could operate at 10 Mbps, while at the same time other nodes
are operating at 100 Mbps. Auto-negotiation takes place each time when
a RJ45 cable connection is made and a link will be established. The
Ethernet Switch advertises its capability for using 10 or 100 Mbps
transmission speed to the connected device and expects this also from
the connected device. This procedure results in an agreement to operate
at a speed of either 10 or 100 Mbps.
The fiber optic ports operate at a fixed 100 Mbps speed and full-duplex
mode to provide the best performance.
