automatically detects and configures the twisted pair port on the converter to the
correct MDI or MDI-X configuration allowing either straight-through (MDI) or crossover (MDI-X)
cables to be used – see figure 18. No user intervention is required.
* Eliminates an entire category of troubleshooting
* No need to identify cable type; straight-through or crossover
* No user intervention required to determine correct button / switch settings

Auto-Negotiation
(IEEE 802.3u)
Auto-Negotiation allows devices to perform automatic configuration to achieve the best
possible mode of operation over a link. The Industrial PoE Switch will broadcast its speed
(10Mbps, 100Mbps) and duplex (half, full) capabilities to other devices and negotiate the best
mode of operation between the two devices.
* No user intervention required to determine best mode of operation
* Optimal link established automatically
* Quick and easy installation
Note
:
If the Industrial PoE Switch is connected to a non-negotiating device over the copper
link, it will default to 10Mb/s speed, half duplex mode.
Pause
(IEEE 802.3xy)
PAUSE signaling is an IEEE feature that is used to temporarily suspend data transmission
between two devices in the event that one of the devices becomes overwhelmed. In the event
that a device needs some time to clear network congestion, it will send out a PAUSE signal to
the other end device, which will then wait a pre-determined amount of time before re-
transmitting the data. Transition's converters will pass PAUSE signaling unhindered; ensuring
that the message is delivered to the end device.
* PAUSE enabled devices allowed to work properly
* Prevents loss of valuable data transmission
* Reduces bottlenecks and allows for efficient use of network devices
Note
:
PAUSE signaling is not standardized over fiber media. Transition's Industrial PoE
Switches will communicate this signaling over fiber between the switches to pass this
signaling on to the other end device.
