Abstract

In today’s constantly advancing modern industries, any system downtime due to component interconnects failures can results in miscommunication, productivity reduction, and can harm financial growth. In recognizing this increasingly costly unplanned downtime, the industry introduced hot insertion and hot swapping technologies to minimize the impact of any such events. Using power off protected multiplexers in your module enables hot swapping support, and allows network admins to replace a failed units without powering down the system.
