suggest you to make exact connection with the Earth Ground.
On the bottom side of the switch, there is one earth ground screw. Loosen the
earth ground screw using a screw-driver; then tighten the screw after earth
ground wire is connected.
2.6 Wiring Fast Ethernet Ports
The switch includes 7 RJ-45 Fast Ethernet ports. The Fast Ethernet ports support
10Base-T and 100Base-TX, full or half duplex modes. All the Fast Ethernet 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 cables.
Note that crossover cables simply cross-connect the transmit lines at each end
to the received lines at the opposite end.
Straight-through Cabling Schematic
Cross-over Cabling Schematic
Note that Ethernet cables use pins 1, 2, 3, and 6 of an 8-pin RJ-45 connector. The
signals of these pins are converted by the automatic MDI-X function, as shown in
the table below:
