Full Power Stack across 5 Switches and Partitioned Power Stack between 3 and 2 switches

[blnprasad]

Hi,

We are planning to use 30cms Power Stack cable between our 5 Switches with 1 RU space between the switches as well. To maintain this 1 RU space and to make use of this 30cms Power stack Cable, I have designed two Options and those file are attached.

In both Option1 and Option2 Data Stack is fully redundant between 5 Switches.

In Option1- Power Stack is fully redundant- Can anyone please confirm whether it is fully redundant or not? Can we configure the Power Stack without any issues?

In Option2- Power Stack is partitioned- Here Power pool and redundancy will be between first 3 switches and second 2 switches separately, but not between all 5 switches. Data Stack is for all 5 Switches in Option2 also. Can we configure like this? Any disadvantages?

Please see the attachments and kindly let me know which option is fine to avoid complications during configuration.

Thanks

Hi,

The maximum number of switches you can power stack together is 4. So, I would do option2.

I have done similar setup as option2 and the power redundancy works just fine.

Hi,

So, will there be any difficulties to Data Stack with 5 switches when we use option2 (Partitioned Power Stack)

In your setup do you have the Data Stack for all 5 switches, for the one you are saying the Power Stack is as option2?

Thanks

Hi,

The power stacking is completely separate from data stacking.  So, you can data stack all 5 and power stack 3 and 2.
