1/10GBase-T autosensing Ethernet port
The S5130-28TP-EI, S5130-28TP-PWR-EI, S5130-52TP-EI, and S5130-52TP-PWR-EI switches
provide 1/10GBase-T autosensing Ethernet ports.

To avoid packet loss caused by interferences as a best practice, layer cables as follows:
•
Use category-6A or above cables and connectors.
•
Do not bundle cables in their first 20 m (65.62 ft).
•
Separate power cords and twisted pair cables at and around the distribution frame.
•
For ports adjacent to one another on the device, the peer ports on the distribution frame is
preferably not adjacent, for example:
{
If the device connects to one distribution frame, connect port 1 on the device to port 1 on the
distribution frame and port 2 on the device to port 3 on the distribution frame.
{
If the device connects to two distribution frames, connect port 1 on the device to port 1 on
distribution frame 1 and port 2 on the device to port 1 on distribution frame 2.
•
Keep the device and twisted pair cables away from the interference source, such as a two-way
radio and a high-power variable-frequency drive.
Combo interface
The S5130-28F-EI and S5130-28PS-EI switches each provide eight combo interfaces. A combo
interface includes an SFP port and a 10/100/1000Base-T autosensing Ethernet port. Only one of
these two ports can operate at a time.
