Subscriber's power outlet (110-240 VAC, 1A, 50/60 Hz, 50W)
Note: The ports of the SDA-4S models support Auto Negotiation, allowing
automatic configuration for the highest possible speed link (10BaseT or
100BaseT), and Full Duplex or Half Duplex mode. In other words, the speed
of the connected device (e.g. PC) determines the speed at which packets are
transmitted through the specific SDA-4S port. In addition, the SDA-4S ports
support MDI/MDI-X automatic crossover, allowing connection to straight-
through or crossover cables.
