High and low thresholds High and low threshold values are the values at which potential problems might occur. For example, in configuring a temperature threshold, you can select the temperatures at which a potential problem can occur because of overheating or freezing. You can compare high and low - Dell 8 | Fabric Watch Administrator’s Guide - Page 36
