CHAPTER
1Product Overview
The DSView®3 management software version 3.3 is a secure, web browser-based, centralized
enterprise management solution that allows users to remotely access, manage, monitor and control
target devices through Avocent managed appliances. A session may be launched to a target device
with a single point of access.
Features and Benefits
Network rebooting and troubleshooting
The DSView 3 software uses industry standard IP connections so that you can easily troubleshoot a
server, or even reboot it, from the Network Operations Center (NOC), from your desk or from any
location in the world. With the DSView 3 software, you can access all of your data center devices
from a single screen - making complex network access and control remarkably easy.
Web-based access and control
The DSView 3 management software provides secure “point-and-click” web browser-based access
to control virtually any data center device using managed appliances from DSView 3 software
clients that may be located anywhere in the world.
The DSView 3 software supports the following browsers:
• Microsoft®Internet Explorer version 6.0 SP1 and later
• Mozilla version 1.7.3 and later
• Firefox version 1.0 and later
• Netscape version 7.2 and later
It is recommended that the browser be kept up to date with the latest version.
Secure authentication and communication
Secure Socket Layer (SSL) encryption may be used to encrypt data traveling within the DSView 3
software system. Users may be authenticated using the DSView 3 software server internal
database, or using an external authentication service.

Unit and user management
The DSView 3 management software provides centralized network access, control and security for
managed appliances. A DSView 3 software administrator may add, remove, delete and change
settings for managed appliances and target devices, including assigning permissions and per-device
contact information, which are stored on the DSView 3 software server. A DSView 3 software
administrator may also assign unique permissions which allow individual users or a group of users
access to units or groups of units.
Proxy server access
The proxy server feature allows keyboard, video and mouse (KVM) and serial sessions to be
proxied through the DSView 3 software server. When a session is initiated with a target device, the
viewer communicates using the Avocent Proxy Protocol (APP) and the DSView 3 software server
makes a direct connection to the appliance.
Virtual media
On certain DSR switch models, the DSRIQ-USB2 module and the virtual media feature allow the
client workstation user to load files onto USB2-compatible target devices when the usual network
resources are unavailable.
Mapping physical drives or image files on the client system as virtual drives on the target device
can accommodate critical tasks required on the target device, such as operating system installation
or recovery, BIOS updating and configuration backups.
System Components
The DSView 3 software system contains the following components.
DSView 3 management software
The DSView 3 software resides on the DSView 3 software server (host or hub computer) and
provides a web gateway and services for managing units (appliances and target devices) using a
web browser. The gateway allows for IP-based video, serial management, Telnet Viewer, third
party Telnet viewer, web browser and other supported session types.
Users may connect to the DSView 3 software server from DSView 3 software clients and use the
DSView 3 Explorer windows to communicate with the system.
DSView 3 software server
The DSView 3 software server contains the DSView 3 management software. The server provides
a centralized database for storing configuration, user, unit and system information. It also provides
services for authentication, access control, logging events, monitoring and license management.
You may configure one or more spoke (backup) servers in addition to the hub server.
The hub server is responsible for maintaining the master copy of the database in a DSView 3
software system. Only one server in a DSView 3 software system may be configured as the
hub server.
