CEF SRx is an efficiently controlled router/switch whose properties are easily scalable by connecting various data transfer modules on the basic device. The CEF SRx combines excellent data communications properties with first-class durability needed under extreme conditions.

The CEF-SRx is maintenance free. The end user only needs to change modules and cables and update the software.

The CEF-SRx is compact in size and its high 2U case is easy to install in a standard 19-inch rack with guide bars or fixed. The installation depth is approximately 50 cm. The aluminium case of CEF-SRx is splash water proof. Also the cable lead-throughs meet the requirements of the demanding IP54 protection class.

An active monitoring unit adds to the reliability of CEF-SRx, measuring temperature and operating voltages, among others. The monitoring unit is able to send an alarm to the user if necessary. The settings and alarm limits of the monitoring unit can be set through the serial communications port (HyperTerminal).
