Can you hot swap the IPK II analog cards?

Yes

Thank you. I am most familiar with the Aspire UX, 8100, 9100 just wanted to make sure.

You can hot swap all cards except the CPU

And the LX Voicemail :-)

Make sure you turn off the busy out switch first. A slide switch on the front edge of the cards. For the VM card wait for it to cycle off after turning on the busy out switch.
