CDV is my specialty
It is not necessary. But, they do periodic updates to the equipment in your home. If you leave it unplugged, you may or may not encounter issues. If you want, you can leave it unplugged and if its a Comcast modem and you experience issues restarting your modem after you restart your services, we will come out and swap the modem for no charge.
Now, if you have phone service with us and you have a monitored alarm, you must leave the EMTA plugged in. That way your alarm can call out in case your home is broken into.

No, it does not, but is recommended that way if there are area wide issues, there would be proper documentation because you modem will report either a connected or disconnect status to Comcast.

This is fine to do. When you return home simply plug the modem back in and it will get all updates and reinitialize at that time. Big B brings up a good point that if you have an alarm and our phone service the emta )phone modem that can do both phone and internet would need to remain plugge in for the alarm to function properly.

If you have cable boxes they will need to be replaced when you come back. As for the modem it is as the others have said the phone modem needs power if you have an alarm system.
Need a "Comcastic" guide? The Great Mog_ur will make Comcast issues disappear. I'm a Comcast...
If you have the phone service.... The answer is yes. This device is called an emta. If its internet only then no.
This expert is helping you out because there weren't many active Comcast experts.

Cable boxes do not need to be replaced and neither will the modem, both will work just fine when switched on again. Do not disconnect power from an EMTA (phone modem) you wont be able to use call forwarding or any other handy feature.
