CHAPTER
1Product Overview
The DSView®3.1 management software 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 management 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 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 management software provides secure “point-and-click” web browser-based access
to control virtually any data center device using managed appliances from DSView software clients
that may be located anywhere in the world.
The DSView 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.
A Video Viewer window allows you to control the keyboard, monitor and mouse functions of
individual target devices connected to a DS1800 digital switch or DSR switch in real time. You
may also use predefined global macros to perform actions within the Video Viewer window, or
create new macros within the window for the device.
Devices connected to a CPS serial over IP network appliance or a CCM console management
appliance may be accessed using a Telnet/SSH applet window.
Devices connected to a DSI5100 proxy appliance may be accessed using an IPMI Viewer window.

2DSView Installer/User Guide
Secure authentication and communication
Secure Socket Layer (SSL) encryption may be used to encrypt data traveling within the DSView
software system. Users may be authenticated using the DSView software server internal database,
or using a Lightweight Directory Access Protocol (LDAP), Active Directory®or Windows NT®
domain external authentication server.
Creating and managing user permissions
The DSView management software provides centralized network access, control and security for
managed appliances. A DSView 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 software server. A DSView software
administrator may also assign unique permissions which allow individual users or a group of users
access to units.
Users may be authenticated using the local DSView software internal database or by an
external server.
Proxy server access
The DSView management software also contains a proxy server feature that allows keyboard,
video and switch (KVM) and serial sessions to be proxied through the DSView software server.
When a session is initiated with a target device, the Video Viewer communicates using the Avocent
Proxy Protocol (APP) and the DSView 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 allows 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 following components comprise a DSView software system.
DSView management software
The DSView management software resides on the DSView software server (host computer) and
provides a web gateway and services for managing units (managed appliances and target devices)
using a web browser. The gateway allows for IP-based video, serial management, Telnet/SSH
applet or web browser sessions.
Users may connect to the DSView software server from DSView software clients and use the
DSView Explorer window to communicate with the system.
