491/10GBase-T autosensing Ethernet portThe S5130-28TP-EI, S5130-28TP-PWR-EI, S5130-52TP-EI, and S5130-52TP-PWR-EI switchesprovide 1/10GBase-T autosensing Ethernet ports.Table 18 1/10GBase-T autosensing Ethernet port specificationsItem SpecificationConnector type RJ-45Interface attributes 1/10 Gbps, full duplex, MDI/MDI-X autosensingTransmission medium and maxtransmission distance• 55 m (180.45 ft) over category-6 unshielded twisted pair cable• 100 m (328.08 ft) over category-6 shielded twisted pair cable• 100 m (328.08 ft) over category-6A or above twisted pair cableCompatible standards • IEEE 802.3ab• IEEE 802.3anTo 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 ispreferably not adjacent, for example:{ If the device connects to one distribution frame, connect port 1 on the device to port 1 on thedistribution 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 ondistribution 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-wayradio and a high-power variable-frequency drive.Combo interfaceThe S5130-28F-EI and S5130-28PS-EI switches each provide eight combo interfaces. A combointerface includes an SFP port and a 10/100/1000Base-T autosensing Ethernet port. Only one ofthese two ports can operate at a time.LEDsSystem status LEDThe system status LED shows the operating status of the switch.
