Features and Benefits
Avocent DSR
®
switches combine analog and digital technology to provide flexible, centralized
control of data center servers and facilitate the OA&M (operations, activation and maintenance) of
remote branch offices where trained operators may be unavailable. They provide enterprise
customers with a significant reduction of cable volume, secure remote access and flexible server
management from anywhere at anytime.
Each DSR switch model consists of a rack mountable keyboard, video and mouse (KVM) switch,
configurable for analog (local) or digital (remote) connectivity. Video resolutions are supported
up to1280 x 1024 for remote users. Enhanced video quality of up to 1600 x 1200 is available to
local users via the video port.
The DSR switch has user peripheral ports for PS/2 and USB keyboards and mice and an SPC port
that may be used to connect to an SPC power control device. An SPC device is an 8- or 16-outlet
device that can be used to control the power state of any attached target devices using the
DS software.
The DSR switches work over standard LAN connections. Users can access target devices
across a 1000BaseT LAN port that is used to establish an Ethernet connection, or directly
through a local port. Each DSR switch model includes a MODEM port that supports V.34, V.90
or V.92-compatible modems that may be used to access the switch when an Ethernet
connection is not available.
The IP-based DSR switches give you flexible target device management control from anywhere in
the world.
Reduce cable bulk
With server densities continually increasing, cable bulk remains a major concern for network
administrators.The DSR switches significantly reduce KVM cable volume in the rack by utilizing
the innovative DSRIQ module and single, industry-standard Unshielded Twisted Pair (UTP) CAT
5 cabling. This allows a higher server density while providing greater airflow and cooling capacity.
The DSRIQ module is powered directly from the target device and provides Keep Alive
functionality when the DSR switch is not powered.
