Chapter 1: Product Overview
Features and Benefits
The Avocent DSR™1021 switch combines 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. This solution provides enterprise
customers with a significant reduction of cable volume, secure remote access
and flexible server management from anywhere at anytime.
The DSR1021 switch is a rack mountable keyboard, video and mouse (KVM)
switch configurable for analog (local) or digital (remote) connectivity. The
DSR1021 switch has ports for connecting servers and serial devices via DSRIQ
modules. A video resolution of 1280 x 1024 is supported for remote users of
the DSR switching system. Enhanced video quality of up to 1600 x 1280 is
available for the local user via the keyboard, video and mouse ports.
The DSR1021 switch includes an SPC, LAN and MODEM port. The SPC port
may be used to connect an SPC power control device to the DSR1021 switch.
An SPC device is an 8- or 16-outlet device that can be used to control the power
state of any attached servers or serial devices using the DSView®software
residing on the user PC. The LAN port is used to establish an Ethernet
connection to the switch. The MODEM port may be used by remote users to
access the switch using a dial-up connection when an Ethernet connection is
not available.
The DSR1021 switch works over standard LAN connections. Users can access
servers or serial devices using:
•A 100BaseT Ethernet connection
•A V.34, V.90 or V.92-compatible modem for remote KVM access
and administration
•The local port
The IP-based DSR1021 switch gives you flexible server management control
from anywhere in the world.
Reduce cable bulk
With server densities continually increasing, cable bulk remains one of
the major concerns of every network Administrator. The DSR1021 switch
significantly reduces 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.

4DSR Installer/User Guide
The DSRIQ module is powered directly from the server and provides Keep
Alive functionality when the DSR1021 switch is not powered up.
The DSRIQ-SRL (serial) module is a DCE device that provides the primary
interface between a serial device and a DSR1021 switch. It provides VT100
terminal emulation, break suppression and port history in a compact,
convenient module.
Access the DSR1021 switch via network connection
No special software or drivers are required on the attached, or host, computers.
Users access the DSR1021 switch and all attached systems via Ethernet or
using a V.34, V.90 or V.92 modem from a PC running the DSView software
application residing on the user PC. User PCs can be located anywhere a
valid network connection exists. The DSR1021 switch can be configured on
a separate network from your data network, allowing access to your servers
even if your applications network is down.
Simple point and click access to any server
When a user activates DSView software, it will display a listing of all computers
and serial devices to which the user has access permission. When a user selects
a server from the list, the video of the selected server is displayed in a Video
Viewer window. Multiple servers can be accessed by one user. Each additional
computer’s video will appear in a separate program window.
Create and manage user permissions with DES
encrypted security
An Administrator describes the configuration of computers attached to the
DSR1021 switch using the DSAdmin management application. Once the
topology is described, the Administrator then establishes which computers a
user has permission to access. Usernames and passwords are derived from
Windows NT®, Windows®2000 or Windows XP, eliminating the need for
redundant user databases. Once the topology is established, the DSAuth
Server software manages the system’s user permissioning. The DSView
software polls the server running DSAuth Server software for access
permissions on power up and every time a switch is initiated for the most
current permissions possible. A refresh is also available for immediate
updates to a user’s access profile. In addition to the permissioning function,
the DSAuth Server software also stores pertinent information about attached
devices in a database. Room location, rack location and server type can all
be stored for quick reference.
