RJ45 Ports
RJ45 Ports (Auto MDI/MDI-X): The RJ45 ports are auto-sensing for 10/100Base-T or 100Base-TX 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 below for straight-through and crossover cabling schematics.

Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
2.6 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ45 port connections. The cable between the switch
and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) in length.
2.7 Wiring the Power Inputs
Caution: Please follow the steps below when inserting the power wire.
Attention: Veuillez suivre les étapes ci-dessous lors de l'insertion du câble d'alimentation.
1. Insert the positive and negative wires into the PWR1 (V1+, V1-) and PWR2 (V2+, V2-) contacts on the terminal block
connector as shown below in Figure 2.6.
