Data Stack and StackPower Recommendation

[sklein]

Hello,

We recently purchased two 3750-X 48-port switches.  We are in the process of connecting the Data Stack and StackPower cables.  The question we have is what is the recommended Data Stack and PowerStack cable configuration if you only have two switches?  All of the documentation that we have seen is for three or more switches. 

Data Stack

Our assumption is that we will go from Stack 1 on the top switch to Stack 2 on the bottom switch.  Do we need to then connect another cable from Stack 2 on the top switch to Stack 1 on the bottom switch?  We would think not, but figure we should check.  We plan on adding another three in the next budget year, which starts in May.

StackPower

Our assumption is that we will go from S-PWR on the top switch to S-PWR XPS on the bottom switch.  Do we need to then connect another cable from S-PWR XPS on the top switch to S-PWR  on the bottom switch?  We would think not, but figure we should check.

Any help on this would be much appreciated. 

Thanks,

Scott Klein

Hello,

Data Stack and Powerstack: This applies to both.

Ideally you should connect stack 2 of the top switch to stack 1 of the bottom switch and connect stack 1 of the bottom switch to stack 1 of the top switch. This gives redundnacy incase a stack port or a stacking cable goes bad which will still result in your stack being up rather than if you just had one stacking unit.

WHen you get the other switches, you can now take the stack and power cables from the bottom and connect them to the now top switch as you've seen in the documentation where the stacks are more than two switches. I hope this helps.

Joel
