Connect the Ethernet Ports
You can use the following information to connect standard Ethernet cables between the ES7528 Ethernet
ports and the network nodes.
•
Ports 1-24 are Fast Ethernet (10/100BASE-TX) PoE ports that are IEEE 802.3af (PoE) and IEEE 802.3at
(PoE Plus) compliant. The ports provide 48VDC at 350mA (maximum 15.4W/port) or provide 53VDC at
606mA (maximum 32W/port). The following table shows the RJ45 PoE pin-out assignment.
•
Ports 25-28 are RJ45/SFP Combo Gigabit ports that support Gigabit/1000BASE-SX/LX/LHX/ZD/ZX
.
Connect SFP Transceivers (Combo Ports 25-28)
on Page 13 for information about SFP 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.
