研華智能EKI-2725I非網(wǎng)管型交換機簡介：

The EKI-2725 supports Gigabit Ethernet. The power is a 12 ~ 48 VDC redundant input design, and is secured with a double protection mechanism:  EKI-2725 will automatically get back to normal operation state. Each port of EKI-2725 has 2 LED’s to show the link status transmission speed and collision status. It also provides a relay output for an event alarm. In the event of a power failure, the built-in LED will activate the alarm to notify administrators. Engineers can simply verify the hardware status by checking the LED, and have troubleshooting easy and quick.
