THIS COULD DAMAGE THE EQUIPMENT. THE EQUIPMENT SHOULD BE IN A CONTROLLED ENVIRONMENT. v Safety Precaution - Static Electricity Follow these simple precautions to protect yourself from harm and the products from damage. 1. To avoid electrical shock, always disconnect the power from your PC chassis before you work on it. Don't touch any components on the CPU card or other cards while the PC is on. 2. Disconnect power before making any configuration changes. The sudden rush of power as you connect a jumper or install a card may damage sensitive electronic components.

The EKI-2525M or EKI-2526M includes a switch controller that can automatically sense transmission speeds (10/100 Mbps). The RJ-45 interface can also be auto-detected, so MDI or MDI-X is automatically selected and a crossover cable is not required. All Ethernet ports have memory buffers that support the store-and-forward mechanism. This assures that data is properly transmitted. 1.1.2 Dual Power Input EKI-2525M/2526M redundant power input design is with power reserve protection to prevent the switch device broken by wrong power wiring. When one of power input is fail, P-Fail LED will turn on and send an alarm through a relay output for notifying user. 1.1.3 Flexible Mounting EKI-2525M/2526M is extremely compact (37 x 140 x 95 mm) and can be mounted on a DIN-rail or a panel, so it is suitable for any space-constrained environment. 1.1.4 Advanced Protection EKI-2525M/2526M supports up to 3,000 VDC surge protection for power line, and also supports 4000V ESD for Ethernet ports. With these 2 strong protections, it can secure equipment against unregulated voltage and make systems safer and more reliable. Further, EKI-2525M/2526M provides currency overload protection with a resettable fuse to ensure that the device component won’t be damaged by overload current. 1.1.5 Wide Operating Temperature The operating temperature of the EKI-2525M/2526M is between -40 ~ 75 °C (wide operating temperature model) or -10 ~ 60 °C (standard model). With such a wide range, you can use the EKI-2525M/2526M in some of the harshest industrial environments that exist. 1.1.6 Easy Troub...
