EXHIBIT 99.15 Avocent Announces Divisional Realignment HUNTSVILLE, Ala.--(BUSINESS WIRE)--May 23, 2006--Avocent Corporation (NASDAQ:AVCT) announced today that, effective June 1, 2006, it will realign its Embedded Software and Solutions Division to report to Tom Miller, Avocent's Senior Vice President of Global OEM Markets. "Based upon feedback from our OEM customers, we have decided to adopt an integrated relationship management approach. Both our traditional OEM appliance team within our Management Systems Division and our Embedded Software and Solutions team will now report to Tom and will work together to offer our OEM customers a more focused and coordinated product roadmap," stated John R. Cooper, Avocent's Chairman and Chief Executive Officer. "The AESS team has continued to create traction in the device management space with embedded management technology," continued Mr. Cooper. "These embedded `building blocks' include IPMI, DVC video compression and virtual media. In addition, AESS has been very successful incorporating these technologies into integrated products, such as remote access cards and blade server management modules marketed as complete management solutions in partnership with our OEM customers. By further expanding the collaboration of these `building blocks' with our appliances, exciting new opportunities present themselves - offering new revenue streams as we build out a complete management stack." Mr. Miller joined Avocent in 2002 and has been responsible for leading the company's sales and relationship development efforts with OEM customers on a worldwide basis, which represented approximately 48% of Avocent's sales in 2005. "Regrettably, Mark Lee, who joined Avocent with the acquisition of OSA Technologies and has been in charge of the AESS Division, has decided to leave Avocent at the end of May to pursue other entrepreneurial opportunities. We thank Mark for his leadership and vision and wish him well in his new ventures," concluded Mr. Cooper.
