3Com Corp has announced that following completion of its pending merger with US Robotics Inc (CI No 3,110), it will reorganize its business around three self-contained units. The enterprise systems business unit will design, market, manufacture and sell enterprise products including hubs, switches, routers and network management software, and will focus its efforts on the enterprise market. The carrier systems business unit will design, market, manufacture and sell carrier class communications systems targeting network service providers. The client access business unit will design, market, manufacture and sell client access products for LANs and WANs through reseller channels into all four served markets of enterprise, carrier, small business and consumer. Bob Finocchio, president of 3Com Systems, is to quit the company. He will continue with 3Com in a strategic counsel role and complete his transition out of the company following completion of its fiscal year, which ends May 31. 3Com would say only he was leaving for personal reasons.
