Hardware Installation
The following table shows the RJ45 PoE pin-out assignment.
All of the Ethernet ports automatically detect the signal from the connected devices to negotiate the link
speed and duplex mode (half- or full-duplex). Auto MDI/MDIX allows you to connect another switch, hub, or
workstation without changing straight-through or crossover cables. Crossover cables cross-connect the
transmit lines at each end to the received lines at the opposite end.
Connect one side of an Ethernet cable into any switch port and connect the other side to your attached device.
The LNK/ACT LED is lit when the cable is correctly connected. Always make sure that the cables between
the switches and attached devices (for example, switch, hub, or workstation) are less than 100 meters (328
feet) and meet these requirements.
