Autonegotiation; Autocrossing - WAGO 852-1411/000-001 Manual

WAGO ETHERNET Accessories 852
852-1411/000-001 Industrial Eco Switch
In this operating mode, core pairs 1 and 2 (+), as well as 3 and 6 (-) are used for
the power supply. A 4-core or 8-core ETHERNET cable of at least category 5 or
5e can be used (see section "Appendix" > "RJ-45 Cable").
Operating Mode B
In this operating mode, the core pairs of the network cable not used for data
transmission are used for the power supply ("spare pair power").
Operating Mode B can be used with the following transmission standards:
• 10BASE-T
• 100BASE-TX
In this operating mode, open core pairs 4 and 5 (+) or 7 and 8 (-) are used for the
power supply. An 8-core ETHERNET cable of at least category 5 or 5e is
required (see section "Appendix" > "RJ-45 Cable").

Autonegotiation

Autonegotiation allows the switch to detect the transmission rate and operating
mode for each port and the connected subscriber or subscribers, and to set them
automatically. The highest possible mode (transmission speed and operating
mode) is set.
Autonegotiation is available to ETHERNET subscribers connected to the switch
via copper cable.
This make the switch a plug-and-play device.

Autocrossing

Autocrossing (MDI/MDI-X, "Medium Dependent Interface") automatically
reconfigures the receive and transmit signals for twisted-pair interfaces as
needed. This allow users to use wired and crossover cables in the same manner
1:1.
