2.4 Network Connection
The EKI-2525P has 5 x RJ-45 ports that support connection to 10 Mbps Ethernet, or 100 Mbps Fast Ethernet, and half or full duplex operation. EKI-2525P can be connected to other hubs or switches through a twisted-pair straight through the cable or a crossover cable up to 100m long. The connection can be made from any TX port of the EKI-2525P (MDI-X) to another hub or switch either MDI-X or uplink MDI port.
The EKI-2525P supports auto-crossover to make networking more easy and flexible. You can connect any RJ-45 (MDI-X) station port on the switch to any device such as a switch, bridge or router.
2.5 Power Connection
The EKI-2525P supports dual 48 VDC power inputs and power-fail relay output.

You can connect an alarm indicator, buzzer or other signaling equipment through the relay output. The relay opens if power input 1 or 2 fails (‘Open’ means if you connect relay output with an LED, the light would be off).
