2.6 Wiring Fast Ethernet RJ-45 Ports
The JetNet 4508 V2 series adopts several of RJ-45 connectors which
support 10/100Base-TX with link speed auto negotiation and auto
MDI/MDI-X functions.
All the RJ-45 ports will auto-detect the signal from connected devices to
negotiate the link speed and duplex mode. Auto MDI/MDIX allows users to
connect another switch, hub or workstation without changing straight
through or crossover cable.
Note:
that crossover cables simply 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 LED will light up when the
cable is correctly connected. Refer to the LED Indicators section for
descriptions of each LED indicator. Always make sure that the cables
between the switches and attached devices (e.g. switch, hub, or
workstation) are less than 100 meters (328 feet).
The supported cable types listed as below:
100Base-TX: 4-pair UTP/STP Cat. 5 Cable, EIA/TIA-568B 100-ohm (100 meters)
10Base-T: 4-pair UTP/STP Cat.3, 4 cable, EIA/TIA-568B 100-ohm (100meters)
