Description

Cisco?s StackPower technology enables the power supplies in a stack of 3750-X units to be pooled into a shareable resource, providing redundancy beyond the two PSUs available in one device. This can happen in two ways- power sharing mode, where the wattage of the entire stack is summed together and distributed evenly, or redundant mode, where the largest power supply is held in reserve, and used only in case of failure, at which point the power is again distributed equally.

The CAB-SPWR-30CM can be used to connect up to four 3750-X switches in a shared pool, meaning up to 8 individual PSUs can contribute to the reliability and uptime of the stack.
