The front panel of GigaX1048 switch features forty-eight RJ-45 10/100Mbps ports (auto MDI/
MDIX), one RJ-45 10/100/100Mbps port, one Mini GBIC slot for fiber connection, and LED
indicators that indicate the condition of the switch.
RJ-45 Ports (Auto MDI/MDIX): The forty-eight RJ-45 10/100Mbps ports are auto MDI/MDIX
