Chapter 1: Product Overview
Features and Benefits
Avocent’s DSR™appliances combine analog and digital technology to provide
flexible, centralized control of data center servers. This solution provides
enterprise customers with a significant reduction of cable volume, secure
remote access and flexible server management from anywhere at anytime.
The DSR appliance consists of a rack mountable keyboard, video and mouse
(KVM) switch configurable for analog (local) or digital (remote) connectivity.
Each DSR model has Avocent Rack Interface (ARI) ports for connecting
servers and serial devices via DSRIQ modules. Video resolution of 1280 x 1024
is supported for remote users of the DSR system. Enhanced video quality of
up to 1600 x 1280 is available for the local user via the keyboard, video and
mouse ports.
The DSR works over standard LAN connections. Users can access servers (or
serial devices) across a 100BaseT Ethernet connection or directly through a
local port on the DSR for remote KVM access and administration, depending
on the model selected. The IP-based DSR appliance 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 DSR significantly reduces
KVM cable volume in the rack by utilizing the innovative DSRIQ module and
single CAT 5 cabling. This allows a higher server density while providing
greater airflow and cooling capacity.
The built-in memory of the DSRIQ simplifies configuration by assigning
and retaining unique server names or Electronic ID (EID) numbers for
each attached server. This integrated intelligence enhances security and
prevents unauthorized access to a server through cable manipulation. The
DSRIQ module is powered directly from the server and provides Keep Alive
functionality whether or not the DSR appliance is powered up.
The DSRIQ-SRL (serial) module is a DCE device that provides the primary
interface between a serial device and a DSR appliance. It provides VT100
terminal emulation, break suppression and port history in a convenient
module. The DSRIQ-SRL is compatible with the ARI port of a DSR system.
These DSRIQ modules eliminate the need for extra rack space or additional
cables. The connection between the DSR system and DSRIQ modules is via
industry standard UTP cabling.

4DSR Installer/User Guide
Access the DSR via network connection
No special software or drivers are required on the attached, or host, computers.
Users access the DSR appliance and all attached systems via Ethernet from a
PC running the DSViewTM application residing on the user PC. User PCs can be
located anywhere a valid network connection exists. The DSR appliance 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, it will display a listing of all computers and
serial devices to which the user has permission to access. When a user selects
a computer from the list, the video of the selected computer is displayed in a
session 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 DSR
using an application called DSAdmin. 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®, eliminating
the need for redundant user databases. Once the topology is established, the
DSAuth software manages the system’s user permissioning. DSView polls the
server running DSAuth 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, DSAuth also stores pertinent information about
attached devices in a database. Room location, rack location and computer
type can all be stored for quick reference.
Access serial devices
If an Avocent CPS810 or CPS1610 appliance is attached to the DSR unit,
operators can gain access to serial devices through the DSView software. When
a user connects to the network using DSView, a listing of all computers and
serial devices to which the user has permission to access displays. Selecting a
serial device will initiate a Telnet session.

Safety Precautions
To avoid potential video and/or keyboard problems when using Avocent products:
•If the building has 3-phase AC power, ensure that the computer and monitor
are on the same phase. For best results, they should be on the same circuit.
To avoid potentially fatal shock hazard and possible damage to equipment,
please observe the following precautions:
•Do not use a 2-wire power cord in any Avocent product configuration.
•Test AC outlets at the computer and monitor for proper polarity
and grounding.
•Use only with grounded outlets at both the computer and monitor. When
using a backup Uninterruptible Power Supply (UPS), power the computer,
the monitor and the DSR appliance off the supply.
NOTE: The AC inlet is the main disconnect.

Rack mount safety considerations
•Elevated Ambient Temperature: If installed in a closed rack assembly, the
operation temperature of the rack environment may be greater than room
ambient. Use care not to exceed the rated maximum ambient temperature
of the appliance.
•Reduced Air Flow: Installation of the equipment in a rack should be such
that the amount of airflow required for safe operation of the equipment is
not compromised.
•Mechanical Loading: Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
•Circuit Overloading: Consideration should be given to the connection
of the equipment to the supply circuit and the effect that overloading of
circuits might have on overcurrent protection and supply wiring. Consider
equipment nameplate ratings for maximum current.
•Reliable Earthing: Reliable earthing of rack mounted equipment should
be maintained. Pay particular attention to supply connections other than
direct connections to the branch circuit (for example, use of power strips).

Installation

Chapter 2: Installation 11
Chapter 2: Installation
The DSR system requires that the DSView, DSAdmin and DSAuth software be
installed prior to use. DSView is the application that allows a user to view and
control a server attached to the DSR system. DSAdmin is used to configure and
maintain the system. DSAuth is a Windows NT or 2000 service used to prevent
unauthorized access to the DSR system. More information on the DS
Management Software suite can be found in your DSView Installer/
User Guide.
The DSR system uses Ethernet networking infrastructure and TCP/IP protocol
to transmit keyboard, video and mouse information between operators and
connected computers. Although 10BaseT Ethernet may be used, Avocent
recommends a dedicated, switched 100BaseT network.

Verification of Ethernet/computer connections
DSR appliance
The front panel of the DSR features two LEDs describing the Ethernet
connection. The top green LED is the Link indicator. It will illuminate when a
valid connection to the network is established and blink when there is activity
on the port. The lower amber LED, labeled 100M, will indicate that you are
communicating at the 100 Mb rate.
Additionally, there are two LEDs above each port number on the front of your
appliance: one green and one amber. The green LED will illuminate when the
attached system is powered. The amber LED will illuminate when that port is
selected by the DSView Client.
DSRIQ modules
PS/2, Sun and USB DSRIQ modules are available for attaching computers to
your DSR appliance.
The DSRIQ-SRL serial module is used to connect serial devices to your DSR
appliance and features two green LEDs: a POWER LED and a STATUS LED.
The POWER LED indicates that the attached computer is powered. The
STATUS LED indicates that a valid UTP connection has been made to a DSR
appliance. The DSRIQ-SRL prevents a serial break from the attached device if
the module loses power. However, a user can generate a serial break with the
attached device by pressing Alt-B in the Terminal Applications menu.
Setting up your network
The DSR system uses IP addresses to uniquely identify the server running
DSAuth, the DSR appliances and the computers running DSView. The DSR
supports both BootP (a subset of DHCP) and static IP addressing. Avocent
recommends that IP addresses be reserved for each appliance and that they
remain static while the DSR appliances are connected to the network. For
additional information on how the DSR uses the TCP protocol, see Appendix B
of the DSView Installer/User Guide. Figure 2.1 shows the DSR in a
network configuration.
