[Notice]
1. The system will automatically retry to recover from the event failure every 20 seconds.
2. To clear the warning PoE Indicator of the recovered port, please re-plug the port cable or re-
open the PoE function of the port via DIP Switch(>=2sec).
2.8 Ethernet Ports
RJ-45 Ports
RJ-45 Ports (Auto MDI/MDIX)
: The RJ-45 ports (LAN 1~5) are auto-sensing for 10/100/1000Base-
T, or 100Base-Tx devices connections. Auto MDI/MDI-X means that the switch can connect to
another switch or workstation without changing the straight-through or crossover cabling. See the
figures shown below for straight-through and crossover cabling schematics.

All ports on this industrial Ethernet switch support automatic MDI operations. Users can use
straight-through cables (see figure below) for all network connections to PCs, servers, and other
switches or hubs. With straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are
connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table below
(
Table 2.3
) shows the 10BASE-T/100BASE-TX/1000BASE-T MDI port pin outs.
Note:
The “+” and “-” signs represent the polarity of the wires that make up each wire pair.
