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 DSR1021/1022 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 to 1280 x 1024 for remote users. Enhanced video quality of up to 1600 x 1200
is available to local users via the video port.
The DSR1021/1022 switch has user peripheral ports for PS/2 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 you can use to control the power state of any attached target devices through the
embedded web server or the DSView 3 software.
Users can access target devices across a 100BaseT LAN port that is used to establish an Ethernet
connection, or directly through a local port. Each DSR1021/1022 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 only significant difference between the two models described in this manual is that the
DSR1021 supports control of up to eight target devices, while the DSR1022 supports control of up
to four target devices. The IP-based DSR1021/1022 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 DSR1021/1022 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.
