And while you are up there, make sure all your fancy plenum and in ceiling speakers are properly secured by cable trays or other 'code compliant' support systems.
You'll never understand just what those "support systems" are all about until you're at a site where several generations of data, phone, 25 pair wire...are all lying on a drop ceiling, you pull on a wire, and 500 pounds of wire, dust, and old ceiliing tiles just mush down to the floor.
