Connect 10/100BASE-TX Ports
You can use the following information to connect standard Ethernet cables between the RocketLinx ES7528 10/100BASE-TX
Ethernet ports and the network nodes.
Ports 1-24 are Fast Ethernet 10/100BASE-TX ports that are IEEE802.3af (PoE) and IEEE802.3at (PoE Plus) compliant. In
addition to the 10/100BASE-TX port features, the PoE ports can provide 48VDC at 350mA (maximum 15.4W/port) or provide
53VDC at 606mA (maximum 32W/port), auto-sensing and automatic power off when cables are removed. The following table
shows the RJ45 PoE pin-out assignment.
The Fast Ethernet ports support 10BASE-T and 100BASE-TX, full- or half-duplex modes. All the Fast Ethernet ports auto-
detect the signal from connected devices to negotiate the link speed and duplex mode. 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.
The Ethernet cables use Pins 1, 2, 3, and 6 of an 8-pin RJ45 connector. The signals of these pins are converted by the automatic
MDIX function, as shown in the following table.
Connect one side of an Ethernet cable into any switch port and connect the other side to your attached device. The LNK LED
lights up when the cable is correctly connected. Refer to
Device Front Panel
on Page 136 for descriptions of each LED
indicator. 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).
The wiring cable types are as follows.
•
1000BASE-TX: 4-pair UTP/STP Category 5 cable, EIA/TIA-568 100-ohm (100m)
•
IEEE 802.3af: 4-pair UTP/STP Category 5 cable, EIA/TIA-568 100-ohm (100m)
•
IEEE 802.3at: 4-pair UTP/STP Category 5e / 6 cable, EIA/TIA-568 100-ohm (100m)
