I need to add a third stackable 3750G switch to an existing stack of 2 and was wondering if the first 2 need to be powered down before I install the third?
Do I need to configure the new switch with anything specifically? (aside from assigning ports, etc.)
I'm assuming since I'll have to move around the backend cable, there will be a traffic interruption?
I typically use tftpd32. it's very simple. You should really use the User Guide for 3750's. You may have to use the archive command if you have downloaded the .tar file. Also, in case you are not aware, you will have to reboot your production switches for the new IOS code to take.
