2-3 RJ-45 Ports
HUG-500S(E) has 5 10/100/1000Mbps auto-sensing ports for 10Base-T, 100Base-TX, or 1000Base-TX
devices connection. The UTP ports can auto-sense for 10Base-T, 100Base-TX, or 1000Base-TX
connections. Auto MDI/MDIX function allows HUG-500S(E) to connect to another switch or workstation
without changing straight through or crossover cabling. See
Cabling
section for straight through and
crossover cable schematic.
2-3.1 RJ-45 Pin Assignments
RJ-45 pin assignments as described in the table below:
Pin Number
Assignment
1 Tx+
2 Tx-
3 Rx+
6 Rx-
“+” and “-” signs represent the polarity of the wires that make up each wire pair.
All ports on HUG-500S(E) support automatic MDI/MDI-X function, users can use straight-through cables
(see figure below) for all network connections to PCs or servers, or to other switches or hubs. When auto
MDI/MDI-X is enabled, either type of cable can be used and the interface automatically corrects any
incorrect cabling. The table below shows the 10Base-T/100Base-TX MDI and MDI-X port pinouts.
