This task can take approximately 60 minutes to complete.
The modular system can have up to six Ethernet switches. They work as redundant pairs and can be purchased only in configurations of 2, 4, or 6. Replacing one of a redundant pair can be done such as to not impact node and data network operation of a live system. However, due to the complexity of this operation, you might want to replace switches during a scheduled maintenance or nonpeak usage period.
