Suppose I have a 3 member stack of 3750x switches. Members a, b and c.
I have all 3 members stacked with all 3 *data* stacking cables in a daisy-chain topology. The 50 cm data stacking cable from switch a (on the very top) to switch c (on the very bottom) just barely reached.
Of course, that means the 30 cm *power* stacking cable didn't reach between a & c. Right now, the power stacking cable goes from a to b, and then another cable from b to c. Leaving me with a useless extra 30 cm power stacking cable.
My question is, can switch "a" receive power from switch "c" through switch "b"? Is this just a big electrical "bus"? What if the power supply in switch "b" is removed?
Just wondering if there is a need for me to get a longer power stacking cable (one of the 150 cm power stacking cables). Would there be any benefit? Is only a certain amount of power shareable through each power stacking cable?
The Cisco Catalyst 3750-X and 3560-X Series Switches are designed for power supplies that provide a single power voltage. This approach simplifies the power supply design and allows aggregation of power, from power supplies in a single switch and across switches in a power stack. Cisco StackPower technology creates a pool of power that shares a common load consisting of all the switches in the power stack. This capability to manage power as share resource is unique to a stack of switches that can operate as a single unit. Therefore StackPower technology is available only on the Catalyst 3750-X switches.
Note that all power available in the power stack is combined into one single large pool of power, and the stack becomes a large single load to the power pool (Figure 2).
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
