Avocent Delivers Multimedia KVM Switches Targeted at SMB Compact and
Versatile Solutions for the SOHO PC and/or Mac Desktop

HUNTSVILLE, Ala. — September 13, 2005 — Avocent Corporation (NASDAQ:
AVCT) today announced its new line of SwitchView multimedia keyboard, video
and mouse (KVM) switches. These switches enable desktop users to share
peripherals such as keyboards, monitor, mouse, scanners, speakers,
microphones, printers, cameras, PDAs and other USB peripherals with up to
four PC and/or Mac computers.

Avocent has been the leading innovator in KVM switching since the ’80s.
Since then the company has focused attention on developing the high-end
data center market as well as small and medium sized businesses. Avocent
technology appears in virtually every major data center around the globe.
The technology used to control mission critical corporate applications has
now been adopted in an affordable line of KVM desktop switches.

“Although we’ve done well selling entry-level two and four port switches in
the past, our focus has been on the mid-market and higher,” said Michael
Helms, desktop KVM product manager. “These new products provide many high
quality features at exceptional values.”

The Avocent SwitchView KVM switch line features a built-in USB hub which
enables the switching of KVM audio and USB hub ports independently or
jointly. For example, users can utilize the peripherals activated from one
PC while working on another. The SwitchView PC, SwitchView MM1, SwitchView
MM2, and SwitchView DVI KVM switches provide varying features depending on
users’ needs.

The SwitchView PC Switch allows users to control up to four PS/2 computers
from one keyboard, monitor and mouse – retaining valuable desktop space for
other peripherals.

The SwitchView MM1 Switch allows users to switch between USB or PS/2
systems, sharing USB devices and controlling multimedia applications. The
SwitchView MM1 model provides independent switching for KVM and two USB 1.1
hub ports With the SwitchView multimedia KVM switch you can use one compact
device to control multiple PCs and share access to your USB devices,
digital camera, CD- ROM, PDA, scanner or printer.

The SwitchView MM2 Switch provides independent switching for KVM and two
USB 2.0 hub ports. This model will support users who would benefit from the
faster speed associated with the USB 2.0 standard. The MM2 also provides
hot-key switching and supports the multimedia keys found on some USB
keyboards.

The SwitchView DVI Switch easily manages two USB DVI (digital visual
interface) computers from a single USB keyboard, mouse and DVI monitor.
With video resolutions up to 1600×1200, the SwitchView DVI switch delivers
crisp images for today’s high-end displays, making it an ideal management
tool for the video enthusiast. Audio, microphone and a built in two port
USB 2.0 hub are added benefits.

SwitchView KVM switches are backed by the Avocent two-year warranty and
technical support. Avocent SwitchView products are available at leading
resellers.
