Exhibit 99.6

                Avocent Completes Cyclades Acquisition

    HUNTSVILLE, Ala.--(BUSINESS WIRE)--March 31, 2006--Avocent
Corporation (NASDAQ:AVCT) today announced that it has completed the
acquisition of Cyclades Corporation, a privately-held company based in
Fremont, California. Cyclades was acquired for approximately $90
million in cash, plus the assumption of liabilities and payment of
certain transaction costs. Cyclades had unaudited revenues of
approximately $60 million in 2005.
    "The Cyclades acquisition accelerates our sales efforts in the
fast growing Linux server and networking infrastructure markets,"
stated John R. Cooper, chairman and chief executive officer of Avocent
Corporation. "Our products are very complementary and we expect to
leverage our respective product lines and relationships to provide our
customers with a more integrated platform for managing their IT
infrastructure in the future.
    "We anticipate the completion of the Cyclades acquisition to
extend the time we normally require to close our books for the first
quarter. As a result, we expect to issue our first quarter's financial
results on April 27, 2006. We expect the first quarter's GAAP results
to include a one-time charge for process research and development
costs. We do not expect Cyclades operational results to have a
material impact on Avocent's first quarter operational income,"
concluded Mr. Cooper.
    The Cyclades purchase was funded from Avocent's existing cash and
short-term investments.

    Forward-Looking Statements

    This press release contains statements that are forward-looking
statements as defined within the Private Securities Litigation Reform
Act of 1995. These include statements regarding the development,
introduction, and benefits of new products and technologies (including
those for the Linux server market), the revenue and earnings from new
products, technologies, and customers in the future, the market
penetration and opportunities for the combined businesses, operational
synergies, engineering and design activities, and the integration and
operation of Cyclades. These forward-looking statements are subject to
risks and uncertainties that could cause actual results to differ
materially from the statements made, including risks associated with
the acquisition and subsequent integration of businesses and
technologies, risks associated with general economic conditions, risks
attributable to future product demand, sales, and expenses, risks
associated with reliance on a limited number of customers, component
suppliers, and single source components, risks associated with product
design efforts and the introduction of new products and technologies,
and risks associated with obtaining and protecting intellectual
property rights. Other factors that could cause operating and
financial results to differ are described in Avocent's annual report
on Form 10-K filed with the Securities and Exchange Commission on
March 6, 2006. Other risks may be detailed from time to time in
reports to be filed with the SEC. Avocent does not undertake any
obligation to publicly update its forward-looking statements based on
events or circumstances after the date hereof.

    Use of Non-GAAP Financial Measures

    Operational income and the resulting calculation of earnings per
share on an operating basis are not measures of financial performance
under generally accepted accounting principles (GAAP) and should not
be considered a substitute for or superior to GAAP. Avocent's
management uses operational income as a financial measure to evaluate
performance and allocate resources within the Company. Management
believes this measure presents the Company's results on a more
comparable operational basis by excluding non-cash amortization
expenses, non-operational expenses associated with acquisitions, and
significant and unusual non-recurring gains and losses on sales of
investments made by Avocent. Avocent believes that operational income
is a measure of performance used by some investment banks, analysts,
investors and others to make informed investment decisions. Other
companies may calculate operational income in a different manner so
this measure may not be comparable to similar measures presented by
other companies.
