Are Stackwise cables hot-swappable?

[tmpoff]

We have two switches that are stacked together with ONE stackwise cable. I now have another one that I would like to install to add redundancy.

Can I install the cable without powering down the devices?

Do I have to reload the switches to get them to recognize the new cable/path?

Thanks in advance for your help.

You should power them off, install the cable, and power them on. I tried a hot install in the lab and it did not recognize the cable until a reboot.

Hope that helps.

Hi,

Yes, you should be able to do with no trouble.

your existing stack have (powered up) with 1 or 2 stack cable, then make sure 1st install the 3rd (new) switch, connect the stack cables making sure its fully secured and then power up the 3rd (new) switch. You should not connect a stack cables between 2 live switches, thats what causes problems. Just make sure when making a stack-connection between w switches, 1 switch must be off-line.

Hope this helps....

Hi,

The switch that you are going to add the to stack must be powered off otherwise it may cause a stack a master re-election and the stack will be reloaded or your config may get lost.

That wasn't his question. Need to read the question.

"We have two switches that are stacked together with ONE stackwise cable. I now have another one that I would like to install to add redundancy."

He is asking if he can connect the second stacking cable to the existing pair of switches. The answer is YES, you can connect a stacking cable to an existing, running stack. It will be detected and folded into the backplane.
