非網(wǎng)管型以太網(wǎng)交換機(jī)簡介：

   The EKI-2725F supports Gigabit Ethernet. The power rating is 12 ~ 48 VDC redundant input design, and is secured with a double protection mechanism: Power Polarity Reverse Protection and an Overload Current Fuse. The former tolerates reverse power wiring while the later secures the system from overload currents. As the power supply turns normal, EKI-2725F will automatically get back to a normal operating state. Each port of EKI-2725F 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, which makes troubleshooting quick and easy. EKI-2725F comes with compact metal housing rated at IP30 to protect against dusty industrial environments.
