Used original Advantech eki-2728 8-port full Gigabit unmanaged Industrial Ethernet switch

Eki-2728 equipment has EKI series standard performance. It provides 12 ~ 48VDC redundant power input design, reverse power polarity protection, overload resettable fuse and dual safety protection mechanism. The former can ensure that when the positive and negative ends of the power connection are reversed, the equipment will not be damaged and will still work normally. The latter can ensure that when the power connection returns to normal, the system will be free from the damage of overload current and return to normal working state. Each port of eki-2728 has indicators of connection status, transmission speed and conflict status. In case of power failure, the equipment will use relay output, LED indicator will light up and alarm to inform the administrator. Engineers can easily carry out rapid inspection and fault diagnosis of hardware through indicator lights. Provide 8 Gigabit adaptive Ethernet ports

It supports 10 / 100 / 1000Mbps adaptation, supports giant frame transmission of up to 9K bytes, has compact structure, supports DIN rail installation, supports 12-48vdc redundant power input and relay alarm, and provides broadcast storm protection.
