Product Overview

Features and Benefits

Avocent DSR® switches combine analog and digital technology to provide flexible, centralized control of data center servers and virtual media, and to 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 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 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 DSView® management software. Additionally, virtual media such as generic removable media and CDROM drives can be connected to any one of five USB ports.

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.
