Ethernet RJ45 port
Each RJ45 port has an adaptive function that supports automatic
MDI/MDI-X connections. You can connect the switch to a terminal device,
server, hub, or other switch using a straight-through or crossover cable. Each
port supports IEEE802.3x adaptation, so the most appropriate transmission
mode (half-duplex or full-duplex) and data rate (10Mbps, 100Mbps or
1000Mbps) can be automatically selected (connected devices must also
support this feature). If the devices connected to these ports do not support
auto-sensing, the port will force itself to work at the same rate as the other
party, avoiding full/half duplex mismatch, the transfer mode will default to
half-duplex, and flow control will be automatically disabled. Gigabit electrical
ports can support up to 1000Mbps.
SFP Gigabit Fiber port
The Gigabit optical port of this product is a 1000Base-LX full-duplex
single-mode/multimode fiber interface. It uses SFP hot-swappable devices and
