Connecting Network Cables
The DES-1228 has 24 ports that support 10/100Mbps Fast Ethernet; it also has 4 10/100/1000Base-T Ports and 2 Combo SFPs. It runs full/half duplex transfer mode for 10/100Mbps and full duplex transfer mode for 1000Mbps. Each port on the DES-1228 supports Auto- MDI/MDI-X. Auto-MDI/MDI-X is a feature that enables the switch to auto sense what kind of cable is used on a port (straight or crossover). This allows any type of cables to be used with the switch regardless of what device is being connected.
AC Power
The Switch utilizes an AC power supply of 100~240V AC, 50~60Hz. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The switch’s power supply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected.
