1.1. Features

Has wire-speed Layer 2 switching function.

Ports 1 to 44 are 10/100/1000BASE-T ports corresponding to auto
negotiation. Also their speed and communication mode can be switched
by configuration. Ports 45 to 48 can be used as a 10/100/1000BASE-T
port corresponding to auto negotiation or an SFP extension slot
exclusively. Also their speed and communication mode can be switched
by configuration.

All twisted pair ports support straight/cross cable auto sensing function.
Simply connect devices with straight cables, whether it is a terminal or a
network device.
(This function does not work if the port communication configuration is
set at Fixed or Link Aggregation. Ports 1 to 44 are set at MDI-X. (default))
