There is no such restriction

There is no such restriction , not to use it. It is just possibly because if there is a master fail over, connectivity to the rest of the network would be lost. If you have redundant links, this should be fine to use the master uplink too.

We are upgrading to 2960 XRs.

How many power supplies do we need for a 4 stack?

I think 2 on the top unit and 1 each on the other 3?

3 stack would be the same, 2 on the top unit and 1 each on the other 2?

Hi,

Hi,

There is no restriction of power supplies for a stack, Stack can operate with all switches having single power supply, but if you want for a redundancy purpose, you can have two power supplies.

Re: Ask the Expert: Catalyst 2960-X and 2960-XR Switches Overview, Configuration, and Troubleshooting

Hi Cisco Experts,

 

I have a problem, I am about to deploy 4 new Cisco 2960-X 24 Ports +POE but my 2 switch are encountering intermittent connection due to uplink / trunk ports facing core switch are experiencing auto-reset. I hope somebody can help me / enlighten me why is it only the 2 switches are experiencing auto-reset on trunk port(s) while the other 2 are okay, knowing that they all have the same configurations and using the same Lan connection to Core switch.

 

Best Regards,

Not sure which image you are using on the 2960X. Can you please load 15.2(2)E8 and check if you see the issue? I think it is a known issue.

Thanks,
