Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the Ethernet Switch’s
10/100/1000BaseT(X) ports to any kind of Ethernet device, 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 the
Ethernet Switch to Ethernet devices.
Triple Speed Functionality and
Switching
The Ethernet Switch’s 10/100/1000 Mbps RJ45 switched port auto negotiates
with the connected device for the fastest data transmission rate supported by
both devices. The Ethernet Switch is a plug-and-play device, so software
configuration is not required at installation or during maintenance.
The half/full duplex mode for the RJ45 switched ports is user dependent and
changes (by auto-negotiation) to full or half duplex, depending on which
transmission speed is supported by the attached device.
Auto-Negotiation and Speed Sensing
The Ethernet Switch’s RJ45 Ethernet ports independently support
auto-negotiation for transmission speeds of 10 Mbps, 100 Mbps, and 1000 Mbps,
with operation according to the IEEE802.3 standard.
This means that some nodes could be operating at 10 Mbps, while at the same
time other nodes are operating at 100 Mbps or 1000Mbps.
Auto-negotiation takes place when an RJ45 cable connection is made, and then
each time a LINK is enabled. The Ethernet Switch advertises its capability for
using 10 Mbps, 100 Mbps, or 1000 Mbps transmission speeds, with the device at
the other end of the cable expected to advertise similarly. Depending on what
type of device is connected, this will result in agreement to operate at a speed of
10 Mbps, 100 Mbps, or 1000 Mbps.
If an Ethernet Switch’s RJ45 Ethernet port is connected to a non-negotiating
device, the default values 10 Mbps speed and half-duplex mode will be set, as
required by the IEEE802.3 standard.
