I am going to pull an analog CO trunk card from a CTX100 (no longer used as now on PRI), and replace it with an RSTU2 to give me 8 more analog extensions on the system.

I don't work on the CTX very much - wondering if it's okay to hot swap the cards, or do I need to shut the system down? Trying to decide if I can schedule this for business hours, or if I need to do an after hours shut down.

Hate to miss Wheel of Fortune.......
