I won this unit through a training program. I already have an ex 90 so I've only verified parts in box and unit functions normally. Cisco EX60 The Cisco TelePresence EX60 is an all-in-one video conferencing system.

These units are in excellent working and cosmetic condition in original box (almost like new). This auction is for the unit only, no additional accessory included. Note: No Power Adapter and no Touch Screen control panel included.
